60th IFLA Conference: Havana Cuba
The 60th IFLA Conference, held August 21- 27, 1994, marked the first time IFLA's annual
meeting was held in Latin America. The Cuban Organizing Committee can be proud of having
hosted a very successful conference under less than ideal conditions.
The Havana Conference also marked the first time that conference participants were provided
with access to the Internet that allowed them to send messages to and from the Conference site.
This popular service was provided by the National Library José Marti and the Center for the
Automated Exchange of Information (CENIAI) in Cuba. An important component of many of the
conference sessions was accessing the information resources available via the Internet to
support various types of library and information services.
Workshop: Telecommunications Options for the 90s
Approximately 250 participants attended the workshop entitled "Telecommunications Options for
the 90s" co-sponsored by the UDT Core Programme, the Section on Information Technology, the
Section on Social Science Libraries, and the Section on Science and Technology Libraries, held
Thursday, August 25. Though IFLA Conference workshops are generally limited to 50
participants, a larger facility was made available to accommodate as many participants from
Latin America and the Caribbean as possible.
The objective of the workshop was to provide libraries in Latin America and the Caribbean with
information on Internet resources and the various telecommunications options to access these
resources. The morning session included presentations on Internet basics, Internet protocols
and the navigation tools that can be used to access networked information. The afternoon
session focused on the communications options including wired, wireless and satellite-based
network access available to users in Latin America and the Caribbean. This was followed by a
panel discussion on user and technical issues specific to establishing network connections in this
region. The workshop materials also included a diskette of files containing information about the
Internet and details on accessing publicly available Internet software tools (courtesy of Apple
Computer, Inc.).
In general, participants indicated that workshop provided very relevant information and
discussions on Internet use. They also suggested that the use of the Internet to support library
operations and services should remain a priority for future IFLA Conferences.
IFLA President announces IFLANET
During his presidential address at the opening of the 60th
IFLA General Conference in Havana, IFLA President Robert
Wedgeworth announced the establishment of IFLANET. IFLANET
will initially offer a listserv and document server to
facilitate the electronic exchange of information between
IFLA HQ and the membership and provide a forum for IFLA
members to communicate with each other. In his address,
Wedgeworth noted that "IFLANET will transform IFLA into a
worldwide communications network for libraries and
librarianship that will transcend the barriers of time,
place and level of development."
IFLA patron sponsor SilverPlatter Information Inc. (U.S.A)
is providing IFLA with the facilities needed to operate an
electronic discussion group and document server to be
established by the UDT Core Programme in conjunction with
staff at SilverPlatter. Initial efforts will focus on
establishing the discussion list for use by IFLA membership
and making general information on IFLA and some IFLA
publications available on a document server. The long-term
objective is to establish a well-managed electronic document
server for use by the IFLA membership and the international
library community that will provide access to IFLA meeting
notices, directory information, publications, conference
proceedings, and other information via the Internet.
The IFLA listserv (IFLA-L) is currently available and
readers are encouraged to subscribe and use the list as a
forum.

Common document formats on the Internet: a brief introduction
There is no doubt that the Internet, in a few short years,
has become a vast repository of electronic information. Yet,
one of the by-products of this ever increasing amount of
information is the multiplication of document formats and
standards used to store it. The spectrum of document formats
moves from simple unstructured text to multimedia documents
that can contain networked links to remote items like images
and sounds. This short article introduces some of the more
prevalent document formats on the Internet.
1. Unstructured text
Unstructured text documents are the simplest form of
document on the Internet. Often denoted by the ".txt" file
extension, these documents contain only a simple string of
characters and are devoid of more complex information. For
example, they do not include information about their
structure e.g., explicitly identified titles, paragraphs,
authors, page layout e.g., font size, or other, more
sophisticated elements, such as diagrams, tables, binary
pictures, sound, or links to other documents. The most
common encoding standards for unstructured text are ASCII,
ISO LATIN 1 and UNICODE.
ASCII
ASCII stands for American Standard Code for Information
Interchange and was developed more than 20 years ago. The
terms "ASCII text" and "DOS text" are interchangeable. ASCII
files contain no formatting -- only text, spaces and
carriage return codes. When a file is in this format, it can
be retrieved into many other programs without additional
conversion, since the software-specific codes have been
removed. Virtually all PC applications accept ASCII data and
can transfer data in the ASCII format. The problem with
ASCII transfer is that it strips the file of typographic,
graphic, and layout elements. In other words, ASCII is a raw
data transfer format. To maintain document formatting, the
sender of a file or document and the receiver still must
have compatible hardware and applications.
ISO LATIN1
The next level up from ASCII attempts to create larger
character sets. ASCII, a seven-bit code, represents only 128
characters, and, thus, is unable to encompass most languages
of the world. The number of bits is important for extending
the number of special characters that can be presented. Even
languages represented in the Latin alphabet use various
diacritics not depicted in ASCII, and many languages use
different alphabets altogether. The International Standards
Organization (ISO) has created an extension to ASCII called
ISO Latin1 that handles some diacritics. This standard
provides a complete set of characters for the processing and
interchange of electronic data in English and French. It
represents an eight-bit character set that provides all the
alphabetic characters, diacritics, and other symbols
commonly used in English and French.
UNICODE
An emerging standard that may replace ASCII is the UNICODE
standard. The Unicode Consortium -- including IBM, Novell,
Microsoft, DEC, Apple and other industry leaders -- has
generated Unicode, a 16-bit code that allows the
representation of 65,536 characters. Latin Alphabet #1 is a
part of the UNICODE proposal and is being considered for
adoption by the International Standards Organization. If
adopted, this encoding scheme will be the basis of a single
world-wide standard for character representation. Since
UNICODE has strong industry support, it is well positioned
to become the new standard character-encoding system for all
the world's languages. ASCII has, hitherto, represented the
only real standard among computers other than IBM
mainframes, but ASCII is limited as it represents only
English.
Rich text format (RTF)
Moving up from ASCII and UNICODE are those standards which
detail how the information is displayed, that is, the actual
formatting of the document. One of the simplest and most
common of these standards is Rich Text Format (RTF). RTF is
an open format which Microsoft developed and is promoting
and which allows the creator of a text file to save some
minimal kinds of formatting, such as bold, italics and
underlined characters. Many programs now allow documents to
be translated easily to and from RTF.
2. Proprietary electronic document standards
Another document format available on the Internet are files
stored in proprietary document standards, such as those
output by commercial software packages. One of the problems
with proprietary standards is that there is no market
incentive for most companies to ensure the cross-platform or
cross-software compatibility of documents. Thus, to be able
to read a document in a proprietary format with all of its
original formatting intact, the appropriate program must be
used. Because Microsoft and WordPerfect are the largest
competitors dividing most of the market share in this field,
most word-processing will translate between Microsoft Word
documents and WordPerfect documents.
To some extent, simple translation across major software
packages is now quite routine. Unfortunately, as packages
have become more complex and have allowed users a greater
range of text-processing options, such as the addition of
graphics, tables, equations, and even sound and motion
picture files, the problem of translating these formats
across applications has increased proportionately.
3. Page description languages
To circumvent some of the problems of proprietary document
production, a picture of the pages of the document is
"captured" or "encapsulated", using what is known as "page
description languages". It is then printed on an
appropriate printer or shown on a screen with a display
program. In general, a page description language is a
programming language used to specify the location and nature
of graphical elements on the output page. This program is
sent to the printer (or another output device), that
contains a computer processor and software enabling it to
interpret the program and produce the printed page as
described.
Because page description languages enable software
applications to transmit an accurate picture of a page
between almost any microcomputer and any compatible printer,
it has become very useful on the Internet to exchange
complex documents. The best-known page description language
is PostScript, a proprietary language developed by Adobe
Inc., and widely implemented on many different kinds of
printers. Adobe has also developed ACROBAT in an attempt to
enrichen ASCII code.
POSTSCRIPT
Today, the dominant page description language is Adobe
PostScript. PostScript is most widely used for transferring
information between applications and platforms, particularly
in service bureau and similar environments. The problem with
page description languages is that once the file has been
transported or imported into another application, it cannot
be changed, apart from basic sizing and positioning
information, without going back to the original file and
originating application, which are not always available. A
PostScript file becomes uneditable (except by gurus who
manipulate the code within the file itself). Sharing a
PostScript file also assumes that the recipient has the
ability to print it.
ACROBAT
Adobe Systems has introduced a new computer file format
called ACROBAT that will function as a graphically enhanced
version of the ASCII file format. Acrobat is an extension of
Adobe's PostScript page-description language: a hardware-
and applications-independent system that allows computer
users to print documents with high-quality graphics and
typography. The Adobe Acrobat system allows users to
transfer, display and print documents with their typography,
graphics, and layout intact, regardless of the receiver's
hardware or applications. The catch is that the receiver
must have the Acrobat file reader. The Acrobat file format
will not immediately replace ASCII as a file exchange
standard because, once a document is put into Acrobat's
Portable Document Format (PDF), it cannot be directly edited
or converted to its original format or ASCII. One of the
benefits of Acrobat over PostScript is that the file sizes
are smaller, which means that they can be transferred more
quickly over slow networks and are faster to print than
Postscript files.
4. Complex documents
More complex documents have begun to emerge on the Internet
with the advent of the World Wide Web (WWW) and the
graphically-oriented WWW interfaces.
Through a format called Hypertext Markup Language (HTML),
users of Mosaic and WWW have access to documents that
contain still images, video, sound, interactive buttons,
forms processing, and a growing list of elements. HTML is
subset of Standard Generalized Markup Language (SGML) -- a
device-independent ISO standard for adding "tags"
identifying content elements, such as headings, chapters,
and paragraphs. HTML has become the de facto standard for
specifying how users can mark up text documents for rich-
text displaying and creating hypertext links to other
objects on the Internet.
A central aspect of HTML documents is embedded links to
other objects, such as images, sound files, video clips,
gateways to databases, or other HTML documents. These links
are in a format known as an URN (Universal Resource Name)
and contain three pieces of information: the protocol
necessary to obtain the information, the system where the
information is located, and the location of the information
on that system.
Depending upon whether the document contains graphics or
other complex elements, the client and server software
"negotiate" over formatting. This negotiation is hidden from
the end user. As part of its request, the client software
sends a list of formats that it understands. If a server has
a choice of formats, or if it can convert one format to
another, it will send the formats that the client
understands.
Once the HTML document is received by WWW client software,
the client reads the formatting commands embedded in the
document and displays the document in the way appropriate
for the system. For example, a client running under Windows
(e.g., Mosaic) could display text marked with HTML as a
"Title" with a large-sized, bold typeface, while a client
designed for a character-based terminal could display the
text in capital letters.
The development of the World Wide Web, and the power of its
client software in displaying multimedia documents, is
considered one of the most revolutionary developments on the
Internet.
This overview provides a brief introduction to common
formats and standards on the Internet for representing
documents. Librarians should also be aware of many other
types of standards and file formats used on the network.
These include formats and standards for storing digital
images, sound and video, for data compression, and for file
archiving. These formats and standards will be discussed in
upcoming issues of the UDT Newsletter.
The Present and Future of the Internet: Five Faces
The following article was written by Anthony-Michael
Rutkowski, Executive Director of the Internet Society. It
was prepared as the keynote address for the Networld+Interop
94 Conference held in Tokyo, 27-29 July 1994. It is
reprinted here with the author's permission. A version of
this presentation with associated Internet graphs and charts
is available on World Wide Web at:
http://www.isoc.org/speeches/interop-tokyo.html
Seven weeks ago, on the way to the Internet Society's annual
International Networking Conference in Prague, I visited
Geneva to meet various international organization officials
and give a seminar on Internet. It was envisioned as a
small gathering for a few interested staff at one of my
former employers, the Telco World's International
Telecommunication Union (ITU).
As it turned out, news of the subject had spread around
Geneva and the event became three separate sessions of
nearly 300 people each in the largest conference room at the
ITU. It attracted people from virtually every global
organization in the city, including 30 different foreign
missions and six ambassadors who participated actively. The
Pakistani ambassador -- who is also the chair of the UN
Humanitarian Affairs Committee and provides his Internet
address on his business card -- addressed the audience
stating that this was one of the most important things now
occurring for developing countries. At the same time, the
ITU itself announced that it had become the largest Internet
access provider in Switzerland and its traffic was
increasing at 20 percent per month.
The Society's own INET conference at Prague more than
doubled over the past year and attracted 1200 people from
105 different nations. Billionaire Wall Street investor
George Soros, in his keynote address to the conference,
called the Internet a critical component for the Open
Society, which was the basis for political and economic
stability and organizational and individual success and
self-fulfillment in the 21st century.
A few weeks ago, in reviewing the "metrics" of the Internet
at the Society, we found that all measures of the network
and its use continued to scale inexorably: ever more
connected countries, gateways, networks, hosts, users,
services and traffic. A network analyst recently noted that
if one of those services -- the World Wide Web -- continues
its traffic increase at present rates, it will exceed the
world's digitized voice traffic in three years. We are now
watching a global internetworking revolution scale in near
real-time. Every 30 minutes, another network connects.
At the beginning of the month, the Washington Post carried
the latest in a series of articles dealing with economic
growth and contours of the "New Economy." Much of the new
growth is coming from many thousands of small, fleet-footed
companies. At the same time, many of the old giants are
being dramatically reshaped by young entrepreneurs who are
in the vanguard of a productivity revolution that is
reshaping the economy. "With the aid of new technology and
new forms of corporate organization, they are finding ways
to do things faster, better and cheaper, revitalizing entire
industries and redefining the terms of economic competition
at the same time."
On this Monday, the 30th Meeting of the Society's internet
standards body -- the IETF -- began in Toronto. This body
conducts its work on the Internet almost continually and
physically gathers three times a year -- typically bringing
together more than 500 people at the meeting location and
multicasting to more than 600 additional sites around the
world. More than developing standards, the IETF is a
sophisticated technology transfer engine in which creative
developers in academic, research, and business environments
are joined in a kind of robust creative "soup" wherein they
imagine, write code, criticize, test, and very rapidly scale
new information tools and services free from stifling
formalities and positions.
And now here at Interop -- Tokyo, we witness the event that
more than any other has come to represent the rapidly
growing one-trillion-Yen, internetworking marketplace and
the enormous networked Information Infrastructure that is
now diffusing into businesses, governments, and homes around
the world. Indeed, at Interop Las Vegas in May, Microsoft
representatives said that PC technology has diffused faster
than any other form of electronic system, and, at about the
same time, they announced that the next version of PC
Windows would ship with the Internet Protocol.
Five Faces of Internet
These different experiences over the past few weeks
symbolize what I call "five faces of Internet" and comprise
the primary focus of my presentation today. Internet is
much more than just a new kind of network for transporting
data. Rather, it is a broad "redefining paradigm" -- in
other words, a fundamental transformation that encompasses:
- the building of information infrastructure from the
bottom-up;
- a robust global mesh for directly linking billions of
computers and thousands of computer processes on telecom
and computer platforms anywhere in the world;
- a means for open collaboration in the hyper development
and evolution of new technologies and applications;
- transformation of the structure, methods and individual
skills within enterprises, institutions, and professions
of all kinds;
- a huge, rapidly growing market sector for internet-
related products and services.
1. Bottom-up Information Infrastructure
The last decade has profoundly transformed the way we
conceptualize and create information infrastructure. The
"old world" was oriented around highly structured monoliths
of the telco and early computer worlds that were planned and
operated by big government and corporations. The basic
plans flowed "top-down" from millions of hours of huge
formal meetings and literal mountains of paper which
purported to chart the future of information infrastructure
for decades to come. They provided a plethora of
abstractions that no one quite understood, under the aegis
of never-quite-defined nor accepted concepts like ISDN, OSI,
and next generation mainframes. Enormous directed monies
were to flow into these projects pursued by national
monoliths, and trickle-down information infrastructure would
eventually settle into place.
There is no intent to denigrate these top-down efforts or
the many people who were involved. Indeed, several years of
my own career and those of many colleagues were invested in
these efforts. However, top-down just did not happen as
planned. Instead, a combination of VLSI, PCs, workstations,
Local Area Networks, routers, and elegant user-friendly
software found an enormous marketplace that motivated
individual initiative and investments. At the same time,
long-haul transport technology offered increasingly cheap
bandwidth, and national governments allowed facilities-based
competition among telecoms and deregulated value-added
services. Under combined pressures from rapid technological
change, competition, and affordable new systems, the world
of information infrastructure began a speedy transformation.
At just the right time, robust TCP/IP technologies were
available to serve as the universal, intelligent interface
among computers. As a result, enterprise networks,
distributed network management and applications, and the
global Internet became universally implemented. Massive
bottom-up infrastructure happened, proliferated, and a new
paradigm prevails.
This has been a remarkable decade-long learning experience
about what information infrastructure is all about, and in
nurturing its development. It's discovery time in
cyberspace, and we are constantly learning about what works
and what doesn't. This is not to say that all top-down
activities are frivolous -- no more than asserting that all
bottom up activity will produce meaningful infrastructure.
Similarly there is a lot more to information infrastructure
than just the Internet.
This "face of the Internet" provides some invaluable models
and lessons about key components of national and global
information infrastructure and where we are heading in the
future. The most prominent of these lessons is that bottom-
up infrastructure succeeds most efficiently and
spectacularly!
2. The Internet Global Mesh
Constant Evolution: Three Stages
The Internet and internet technology has been growing and
evolving since its inception in Vint Cerf's imagination and
first articulation more than 20 years ago on the back of an
envelope in San Francisco. At the outset, it had multiple
facets that addressed real needs: a means to share
information-system resources across multiple diverse
platforms, a highly robust self-healing network that could
operate across almost any medium to survive nuclear
holocaust, and a way to bring together experts spread across
the world in "collaboratories" to create, innovate, improve
and produce in many different research areas.
It is now into the third stage of that evolution. The first
stage was the early years under the aegis of the US DOD ARPA
and the province of a relatively small, closed community.
Those people not only developed the technology, but the
cooperative mechanisms and institutions that allowed it to
scale the network and further innovation to occur. The
genius of it all can still be appreciated at major Internet
meetings, which typically bring together a significant
cross-section of world's most highly motivated and
innovative computer networking communities.
Following DARPA's divestiture of the network and the
technologies in the mid-80s, the second stage unfolded. It
represented a period of major development by: 1) vendors for
a growing enterprise internet market, 2) the USA National
Science Foundation, NASA, and Dept of Energy and their
counterparts in other countries who scaled the network to
support open global academic and research activities, and 3)
early innovators in the business sector who began using the
capabilities to provide public access services. Interop
itself was a key part of this second stage, as it fostered
massive investment in private, open-systems infrastructure.
The third stage is now unfolding as almost everyone,
everywhere who provides, uses, promotes, or funds
information systems and infrastructure becomes involved in
the growth and use of the Internet, its technologies, and
applications. If the first stage took us to 2000 hosts over
the first 10 years, and the second state scaled the
connectivity from 2000 to 1 million over eight years, the
third state of Internet growth is now marked by host counts
that will likely proceed from 1 million to 100 million over
the next five years. The growth of the attached networks is
now publicly announced every three days, and we are
literally watching it grow before our eyes.
Dimensioning Internet
The Internet is generally dimensioned two different ways.
The core portion consists of the subset of registered
internetworks that are known to have IP connectivity among
themselves; the larger Matrix Internet popularized by John
Quarterman consists of the core Internet plus all the
networks known to be connected to it by some lowest-common-
denominator application like messaging.
The Core Internet and its metrics
At the end of May, there were 435 760 allocated network
addresses, 47 846 registered at the global Network
Information Center, and about 35 000 known to have
connectivity among themselves. For the last several years,
the most widely used backbone network -- the NSFNet -- has
provided a useful reference point for making consistent
measurements.
Total networks increased at the rate of 160 percent last
year; 183 percent outside the USA. As of July 1, IP traffic
is being routed to networks in 83 different nations. It's
known that the European CERN backbone usually sees more
reachable networks, and with the emergence of commercial
public Internet backbones as well as the termination of
NSFNet next year, the total number is likely to increase
even faster.
Another major trend -- in addition to globalization and the
rapid increases -- is revealed in analyzing the kinds of
new networks attaching. Most are commercial in nature.
Specific focus on both the Asia-Pacific and European regions
shows that about a year ago, the number of networks in most
countries with significant GNPs began to scale significantly
with about 1500 connected networks in each country. The
trend seems unabated.
In addition to dimensioning the Internet in terms of
networks, it is also possible to do so by reachable computer
hosts. Since the earliest days of the Internet, Mark Lottor
has been executing an Internet Walk script over several
weeks to produce an actual list of every reachable machine.
The results are generally released every three months. At
the end of December 1993, the number of hosts was 2.217
million. The count increased 69 percent over 1993.
Lottor's hosts reachable dimension of the Internet is
regarded as particularly significant because the Internet's
most basic function is providing connectivity among
machines. It is also used in estimating the number of
Internet users based on a 10:1 ratio of users per host --
realizing that this is an enormously variable ratio that
encompasses everything from the PC on someone's desk to a
gateway host supporting millions of users on some other
network or commercial service.
Internet traffic is also highly important in understanding
usage patterns among countries and among the hundreds of
technologies employed as services on the Internet. Traffic
on the largest backbones has been doubling every year, and
for 1994, seems likely to triple. Many smaller local
backbones have experienced regular traffic increases of 20
percent per month. Outside the USA, many nations have
experienced initial annual traffic increases measured in the
thousands of percent.
At the individual service level, it is worth noting that
file transfers account for the largest amount of traffic
(around 37 percent currently), with messaging totaling only
around 18 percent. The most interesting new services from a
metrics standpoint are the browsing variety like World Wide
Web and Gopher. WWW, in particular, has grown spectacularly
to account for 6.1 percent of the entire NSFNet backbone
traffic and grew at the unprecedented rate of 341 000
percent in 1993. New Web servers have been added at the
rate of 12 per day over the past three months, and each can
support many implementations. This currently amounts to
almost a terabyte a month of Web traffic. If this growth
pattern persists, some have calculated that, in three years,
it will exceed the total world voice communication traffic.
The Matrix Internet
The core Internet's massive size, high performance, and open
connectivity has proved a magnet to nearly every other kind
of computer network. As a result, many other large and
extensive networks have attached themselves to the core
Internet's periphery. This includes networks based on
specific platforms like BITNET, FidoNet, AppleLink, Minitel,
and UUCP networks, as well as specific application networks
for Email -- for which there are numerous examples like
X.400, AT&T mail, MCIMail, SprintMail, CompuServe, etc.
These peripheral networks create a larger Matrix Internet
that currently reaches 154 countries, and provide many
millions of people with lowest common denominator Email
connectivity. In this capacity, the Internet is truly the
world's universal electronic messaging backbone.
3. Open Collaboration and Development
Just as the Internet is technologically a virtual matrix
among up to 4 billion computers and 64,000 process ports on
each of those computers, so it is also a matrix among 20-30
million people who are directly or indirectly using those
computers and processes. This is an enormously empowering
capability that allows almost instant creation of
workgroups, discussion groups, and audiences of all kinds.
The capability transcends time zones, national and
organizational boundaries, and, in the near future, even
language. In its ultimate extrapolation, it is the ultimate
open society where anyone, anywhere can provide or receive
any information to anyone within seconds.
From its inception, the Internet was intended as more than
just a computer network. It is also a means of facilitating
collaboration and development at great speed -- sometimes
described as technology transfer among disparate groups with
different strengths like academics, industry researchers,
and business entrepreneurs. This activity has taken two
forms: 1) research and development of new, distributed,
network techniques and applications, and 2) innumerable user
populations employing the Internet and its technologies as
tools to enhance their specific professional activity or
pursuit.
An entire new engineering and research discipline has been
cut out of whole cloth -- distributed, autonomous networking
-- complete with its own development dynamics and methods.
Mosaic, httpd, Gopher, Archie, Veronica, Collage, Eudora,
POP, SMTP, Netfind, Knowbots, NFS, NNTP, VAT, and SNMP are
examples of some of the more popular, client-server products
to come out of the Internet innovation "soup".
With amazing rapidity, ideas for a new application or
service are vetted by a discussion group or at IETF "BOFs"
and proceed through a standards working group. At the same
time, the code is placed on a network server. In the
process, innumerable users employ the code, increase the
market, refine the code, and a large commercial market that
is finely tailored to end user needs emerges in a matter of
months. Even commercial proprietary code is being
distributed on the network to test the marketplace -- as is
the case currently with 32-bit versions of Microsoft Windows
operating-system code being distributed concurrently with
new versions of Mosaic. This process of developing running,
standardized code through the Internet has been highly
successful.
It is the more general user populations, however, who are
embracing the tools in vast numbers across the planet. The
enormity of the implications is just beginning to be
understood. For example, it is asserted that 80 percent of
all the scientists who ever lived are on the Internet today!
And in each of these fields, the people "networked"
constitute the majority of early adopters and innovators.
4. Transforming Enterprises, Institutions, and Professions.
The effects of large-scale networking of enterprises,
institutions and people are now being realized. Certainly
traditional barriers, whether they are reporting
hierarchies, institutions, country or geography, are being
obliterated. There is also a certain "compelling" effect
that, beyond a certain point, promotes ever larger numbers
of people to become networked. Not having an Internet mail
address today has become a major liability in many
businesses and professions.
The result has been to transform old institutions, create
new network-based enterprises, and bring about programs to
implement these transformations. The best known of the
latter is the Clinton Administration's Reinventing
Government initiative. However, on a smaller scale, efforts
are now underway in Canada, Chile, Argentina, France, and
Poland -- as well as many international organizations.
Some major older corporations like IBM and Chrysler have
embarked on well-known efforts to get Internet technologies
introduced among their employees to break down internal and
external barriers. In an increasingly competitive
environment, lacking network connectivity and employees,
with the skill to use the network tools, is a major
liability that is quickly reflected in either diminishing
market share or lost opportunities.
An entirely new and potentially massive field is now
emerging around the Internet and distributed networking.
Connectivity is only one component. More significant (and
perhaps more difficult) is obtaining and retraining people
to use these tools effectively in many different
enterprises. This daunting task involves not only
equipment, but cultures and attitudes. And, it also
pervades every office in a corporation or institution, from
the CEO to the average staff member in every department.
Not suprisingly, there is now a focus on developing these
skills at the elementary and secondary school levels so that
children, from an early age, are able to use and create
information on computers, to discover and make available
networked information resources, and to collaborate
seamlessly across networks with their peers. These are the
survival skills of the rapidly emerging, global,
internetworked environment.
5. A Huge Market Sector
The estimated 20-30 million users on the Internet constitute
an ideal market. The users are predominantly young, middle
to upper class, well-educated, and highly motivated. As the
number of Internet users grows another two orders of
magnitude, these characteristics are likely to remain, in
addition to becoming ever more global.
The Internet provides an exceptionally low cost mechanism
for interacting with this audience. This interaction not
only includes public relations and advertising, but testing
of target audiences, sales, and customer support.
The principal caveat concerns the strong traditions for
propriety and privacy that rule out mass mailing or other
intrusive techniques. Such misconduct or fraudulent
behavior can also propagate very quickly.
The Future
These different facets of Internet will assure an exciting
and constantly evolving future.
It seems meaningless to talk about "what's after the
Internet" anymore than to talk about what's after the
telephone. As long as we have computers speaking to other
computers via distributed networks, we will have internets.
Indeed, a 100 years from now, history may well record the
emergence and implementation of an Internet protocol as a
profound turning point in the evolution of human
communication -- of much greater significance than the
creation of the printing press.
No other form of human communication other than actual
meetings allow people to interact with each other in a
collaborative fashion in short time-scales. It is this
capability of rapid, large-scale, low-cost interaction of
people and sharing of information that are unique Internet
properties -- which have profound implications across a
broad spectrum of human activities.
Important Indicators
It is difficult to predict where all the different facets of
the Internet are leading us. In the near-term, we can look
at events currently underway to chart likely developments in
the coming months.
Business on the net
Certainly, the many initiatives using applied encryption
technologies and dove-tailing with pre-existing EDI work,
point to all kinds of business-related activity on the
Internet. However, this is not likely to displace "free
information" given the ever increasing use of the Internet
by public institutions, for commercial public relations, or
individuals sharing information.
Ubiquity
Other major indicators include both the ubiquity of the
access, and the ease of setup and use by ordinary people.
Access involves the diversity of the media being employed
(such as local dialup, freephone dialup, CATV LANs, N-ISDN,
and VSATs) and the ever expanding number of service
providers -- especially major carriers and local resellers.
Resellers are especially important in this phase of internet
evolution because of the frequent significant level of
interaction with customers in using the technology.
However, some of the newly emerging software for PC
environments is so object-oriented and self-configuring that
only minimal computer skills are required.
What Modulates Internet Development?
In the face of all these positive indicators, however, it is
useful to consider what kinds of conditions result in the
growth or stifling of internet developments. Over the past
few years, some specific information on Internet diffusion
has become evident.
Plainly, many external conditions modulate implementation
and use. For example, available capital for investment is
always a major factor with any new technology. Even with
basic telephone systems, the correlation of telephone lines
versus national GNP is almost a straight line. However, the
diffusion of internet technologies, networks, and use
require conditions that are unique and go well beyond just
capital investment to a host of factors that collectively
are sometimes called "culture."
A threshold condition is the freedom to introduce and
operate Internets without significant governmental or
institutional impediments. The Internet consists almost
entirely of tens of thousands of private networks,
constructed and operated by largely private initiative. The
Internet functions very effectively on a global scale
through a number of multilateral and bilateral agreements
among backbone service providers and end-user networks.
The Internet is a creature of the unregulated, highly
dynamic computer networking field -- not the traditional
regulated monopoly telecom environment. The Internet does
best where the environments are subject to little or no
regulation of any kind.
Internet monopoly environments are invariably the worse kind
-- being antithetical to the very concept of what the
Internet is all about. Such environments are also contrary
to the Annex on Telecommunications in the new General
Agreement on Trade in Services (GATS) and the appended
schedules of specific commitments by 96 signatory countries
plus the European Union. These provisions elaborate on some
of the desirable conditions needed for Internet fertility,
namely access to markets and cost-oriented underlying
transport circuits.
However, even in competitive environments, some regulatory
authorities have a penchant for becoming involved in the
operations of Internet providers -- either reviewing
business plans or operational agreements. Given the
incredibly fast, changing operational dynamics of the
Internet scene, such intrusive regulation is inevitably
stifling, as backbone providers increase in number and move
from bilateral to multilateral arrangements among themselves
to lessen the complexities and enhance ubiquitous
connectivity.
Other major diffusion factors include the cost of underlying
transport bandwidth and the ability to acquire current-
technology computers and software at low-cost. These
factors go both to the national competitive conditions for
basic telecom services and overseeing the pricing practices
of dominant carriers.
Dominant carriers in most countries often attempt to charge
prices for underlying circuit capacity that are much greater
than the actual costs -- principally in a misguided attempt
to force customers to use the carrier's own value-added
networks and technologies, and to prevent competition. The
great circuit price disparities between Europe and the USA,
for example, prompted the European Nuclear Research Center
(CERN) two years ago to document these practices publicly
and plead for a change.
Because end user computers and peripheral hardware are such
a fundamental component of Internet growth and development,
national practices which heavily tax and restrict computer
imports and use, also have a major adverse effect on
Internet diffusion. Restrictions or taxes on the use of
modems, for example, have widespread negative effects.
The Challenges and Promises
No electronic network mesh has consistently grown on the
scale at the speed of the Internet. As a result, it has
throughout its history been constantly challenged to develop
new technologies, standards, and administrative techniques
to provide greater bandwidth and additional services to more
users through ever more complex architectures. However,
each order of magnitude scaling becomes more difficult.
Problems associated with addressing and security seem
largely transitory -- with a combination of technology, new
standards, and administration providing effective solutions.
The next few years will likely witness nearly every computer
in the world being potentially connected to an internet.
This seems well within the realm of feasibility. However,
what numbers are actually connected to the Internet or
accessible -- through the Internet and at what bandwidths or
time periods -- depends largely on the available underlying
infrastructure and cost of service.
Bandwidth seems destined in the long-term to approach zero
within and among most metropolitan areas of the world, but
the increasing complexities of managing ever larger numbers
of Internet networks is going to drive operating and
maintenance costs up. The result for end users may mirror
the computer world where the performance just keeps on
increasing at relatively constant cost. In fact, the
evolution of computers and computer networks is sure to
proceed concurrently. And collective innovative Internet
genius will doubtlessly produce an endless stream of
imaginative applications and tools.
It is at the human and institutional levels that major
unknowns arise -- but also offer the greatest promise. The
autonomous, heterogeneous, flat model of the Internet seems
intrinsically a good one. It will be constant discovery
time in Cyberspace, but a world of shared minds that
transcends the accidental boundaries of history, the
distance of geography, the machinations of institutions, and
the mischief of manipulation, is potentially one filled with
discovery, fulfillment and fascination for all peoples --
individually and collectively.
The Internet Society, as the international organization for
the Internet, is dedicated to help make this happen.
