The Danish network for research and
education, DENet, which is operated by UNI-C, will be upgraded to a high speed
network before the end of this year when UNI-C establishes 34 Mbps connections
to universities in five major Danish cities. The connections are integrated with
the present network structure. This high speed network has been preceeded by one
and a half year of preparation. It is a tale of cooperation between three
ministeries.
The Ministry of Industry designed a program to fund
increased cooperation between public research and industrial development. In the
beginning of 1994 this inspired the Danish ministry of Research to combine the
possibility of pushing for improved highspeed networking technology with the
provision of a fullblown high speed networking service for research, education
and industrial development.
The third ministry, the Ministry of
Education -- represented by UNI-C in this context -- took on the task of writing
the applications and performing the procurement by invitation to tender and
subsequent negotiation of terms with the chosen partners. The whole procedure
took nearly two years and would have failed without the support from all three
ministeries.
The new service is supplied by the Danish telecom
operator, TeleDanmark. It consists of 34 Mbps connections to their new ATM
structure, which is inaugurated at the same time. The service is in the first
instance pure IP, later on it may be relevant to employ native ATM virtual
connection through the network. The developmental aspects of the contract are
added by the company Telebit Communications A/S, who recently were the first in
the world to demonstrate a running implementation of the new IP version 6 on
their router equipment. Their main contribution will be to provide a suite of
additional IPv6 functions in their terminating equipment. It is important to
stress that industry is invited to use this network to develop new services and
applications. UNI-C plans to use the high speed network as a basis for a
multimedia-oriented EU-project, Mediator 2, where the purpose is to construct a
market for multimedia halfproducts on the net.

Dr David Hartley (UKERNA)
The opportunities and challenges
afforded by broadband technology are now understood even though the real
applications have yet to be discovered. As with previous networking
developments, the best way to develop and discover those applications is to
faciltate them in the world-wide education and research community. This is the
mission of the national research networks. European national research networks
are at various stages of development in the broadband area and the time is ripe
to seek to develop a broadband interconnection between them. The European
Commission has recognised this opportunity in the context of their programmes
for the support of research, and they have invited proposals under a joint
ESPRIT/Telematics initiative. The TEN-34 group, which includes in essence all
the European national research networks, was formed to respond to the need and
to the Commission's invitation.The challenges of this project are many and
include reconciling the different detail desires and aspirations of a large
number of countries, addressing the European Commission's politics and
procedures and, not least, persuading the Public Network Operators of the
requirements and opportunities for supporting advanced and innovative research
networking. This is proving to be no mean task.

The Faroese flag was hoisted on the Internet map in January this year when
the research institutions in the campus area in Tórshavn got their
Internet connection through a 64 Kbit/s leased line between the University of
the Faroe Islands and UNI-C in Lyngby, Denmark. An optical fibre backbone net
connecting the LAN¦s gives the users on the campus directaccess to the
Internet. Other users, mostly schools and educational services, use a dial-up
connection. A NetWare server is acting as an SMTP gateway for the "sleipnir.fo"
domain and providing POP3-services as well. This simple information
infrastructure - including a combined FTP- and WWW-server - will hopefully put
the Faroe Islands in a feasable place in cyberspace.
Iceland - who was connected to the Internet in 1989 - has experienced an explosive increase in the use of Internet. At the time of writing approximately 120 institutions/companies are connected and around 40 WWW servers are registered. Upgrades of the leased line to Stockholm (established 1990) from 128 Kb/s to 256 Kb/s in May 1994 and further to 1 Mb/s in September this year have appeared to be exploited almost from day one.

9:00 - 10:30 Scientific publishing on the net - Practice and perspectives
Stevan Harnad
Trade periodical publishing differs from
scientific/scholarly periodical publishing in that trade authors publish to sell
their words whereas scientific/scholarly authors write to disseminate their
ideas and findings. In the Gutenberg Era of print on paper, these two distinct
motivational structures could not be distinguished, because both trade and
nontrade authors had to adopt the trade model owing to the high expense of paper
publication. Nontrade authors had to make the "Faustian Pact" of
assigning copyright to their publishers so their work -- and the publishers'
substantial investment -- could be protected from "theft," even though
only the publishers' revenues were at issue: nontrade authors would just as soon
readers stole their words (as long it was just to read them, rather than to
claim them as their own!). The consequence of the Faustian Pact was that the
scientist/scholar's potential readership of fellow specialists, already tiny at
the best of times, was further reduced by the necessity of paying for access to
the printed words; moreover, the print was slow in appearing and the access to
it neither easy nor efficient. In the PostGutenberg Era of electronic networked
publication this Pact is no longer necessary. For a small page-charge, nontrade
authors can make their work universally and permanently accessible for free in
refereed electronic journals and preprint/reprint archives. The enhanced impact
and productivity this will bring to science and scholarship will issue not only
from the unprecedented increase in access to ideas and findings, but from an
interactive dimension that had been absent ever since the word first parted
paths, with the advent of writing, with the speed of thought that it and enjoyed
since the advent of speech. This "scholarly skywriting" may prove to
be the PostGutenberg Era's greatest legacy.

11:00 - 12:30 Libraries on the net - Practice and perspectives
Søren Christian Hansen, Silkeborg Bibliotek
The aim of
the project is to establish the library as a local center for online information
and communication. Since April 1995 our patrons, as the first Public Library in
Denmark, have free access to the Internet from six computers. We estimate, that
access to the net means 20.000 library visitors per year. Recently we have
developed the 3rd release of our Homepage. By now the citizens of Silkeborg will
have modembased access to Internet and to local conferences. These conferences
are called "The Electronic Community Center". Library staff and
volunteers are overseeing the conferences, which enable the citizens to
participate in discussions about local politics, get advice from an expert or
colleagues or publish your own poems. The WWW-based library catalogue is now
available through our Homepage. "Silkeborg - Digital City": The aim of
this part of the project, which will be implemented during Spring 1996, is to
provide information from Silkeborg to citizens and to the Internet. "The
Elektronic Town Hall". The aim of this part of the project, which will be
implemented during Autumn 1996, is to establish contact to the Town Hall, so
that citizens can communicate with local authorities and the town councillors.
In Denmark the IT debate is focusing on the A-team and the B- team, where the
A-team is skilled IT users and the B-team is nonusers. This debate points at the
Danish public libraries having a responsibility to educate the B-team.

The Internet and the network services are
joint important forces shaping the library from a physical place to a virtual
library. This new library will be available through the network and a computer
at the users desktop. Today we experience the beginning of this transformation.
We have on-line catalogues, CD-ROM access trough network, information and
fulltext articles in the World Wide Web etc. In the virtual library most of the
information will be books, articles and multimedia information stored in huge
databases and distributed through the network. The information can be accessed
instantly, independent of time and physical distribution constraints. This
presentation gives an overview of ongoing activities within the field Digital
Libraries, Virtual Libraries, Cybraries or Electronic Libraries.

Ole Husby, BIBSYS
Some 2 years ago, with everybody busy
discussing what "Virtual Library" might possibly mean, the VLs emerged
overnight. Made possible by a syntheses of (1) the fact that the hypertext
paradigm is just what libraries need, (2) the tools HTML and HTTP for handling
hypertext and (3) the rapid connection of everyone and everything to the
Internet.
I will treat 3 main topics:
Delivering traditional library services via the Internet: Involving
the "competing" network standards HTTP and Z39.50, and how they might
interoperate.
Cataloguing the Internet: Using traditional library techniques like
cataloguing and classification, or "automatic" indexing engines.
Integrating the primary and the secondary documents: Implementing the
obvious hyperlinks between the catalogue card and the book, or merging the
metadata into the electronic document itself. Considering electronic publishing:
is this a task for libraries?

Erla Sigurðardóttir
What is ODIN?
In the autumn of 1993 the Nordic Ministers of Culture and Education decided
to establish a Nordic School Data Network
- later to be named ODIN. The Network was introduced by the five Nordic
Prime Minister in March 1994.
There is a political wish to create a Nordic infrastructure to stimulate
and support a Nordic school community. There is a political wish to give high
priority to a further development of the Nordic dimension in school curricula.
It is easy to see the need for a powerful tool to enhance ongoing activities and
to make it possible for many more to get involved in Nordic educational
co-operation. The learning activities in schools become more and more oriented
on independent and investigative learning. The ability to acquire skills and
knowledge has a close connection with the ability to use new information
technology.
The components of the ODIN-network are the national school data
networks of the Nordic countries including the autonomous areas, i.e. Denmark,
Faroe Islands, Greenland, Finland, Åland, Iceland, Norway and Sweden. The
nineth component is the Nordic "plaza", where you will find Nordic
projects, institutions etc. described.
How is ODIN organised?
The organisation of the Nordic School Data Network is decentralised, with
the main responsibility placed with the educational authorities in each
country.
The aim of the Nordic co-operation is to solve common problems and exchange
know-how. The Nordic Council of Ministers supports certain common tasks
financially, such as courses in how to use the network. The main part of the
development of the national networks is though taken care of by each land.
ODIN working groups
The Steering Committee of Nordic School Co-operation (NSS) appointed three working groups with one member from each Nordic country:
The pedagogical group and the technology group have five members, i.e. from
Denmark, Finland, Iceland, Norway and Sweden. The information group consists of
nine persons, as the autonomous areas, i.e. Faroe Islands, Greenland and Åland
also are represented in that group. The nineth person is a a Nordic
co-ordinator who is the chairman of the group.
What is the purpose of ODIN?
The purpose is to create a complex environment for relevant information
from the entire Nordic area, accessible by each individual school. By making
the electronic traffic easier within the Nordic region, Nordic references still
remain as a realistic choice for today's school-children and teachers, a choice
where one has the possibility of finding other people, items or information of
interest.
Another purpose is to create a communication tool which utilises the Nordic
languages correctly, and which can be used for advanced pedagogical purposes
for pupils, teachers and other interested parties. The different languages - at
least the Scandinavian ones - become natural tools, when finding the goals you
search for. Swedish is not solely the school subject you once neglected, but a
code that guides you through the net. The special Nordic letters, such as ð,
þ, ä and ö, remain unaffected in spite of the Anglo-dominance in
the (cyber)world out there.
The future?
The ODIN-network is still young and many possibilities are still to be
discovered and taken advantage of.
Official Nordic institutions are making their own home-pages. Nordic
Museums and Nordic Broadcasting Companies see a probable forum for their
information on the ODIN-network. The Baltic countries are curious about the
advantages of participating in the ODIN concept.
New R&D-projects are
being launched within the frames of ODIN.
The ministerial decision of
establishing the ODIN network initiated and speeded up the development of the
national school data networks in the Nordic countries. It will be interesting
to see how the innovation will take form in the different countries, find how
not only school children but also their teachers will benefit from the network.

Although there is a tremendous interest by
schools world wide in using the Internet, setting up an Internet program for an
individual school is difficult. Like many schools, the Bernadotte School has too
few computers. We are limited to a single dial-up Internet connection. And like
all schools, we are having to learn by trial and error how to integrate Internet
use into the curriculum. In spite of these problems, three classes at our school
have started using the WWW and e-mail to publish their own work and to
communicate with other classes around the world.
In my talk I will report
on one of these projects and mention some other ways the Internet is being used
at the Bernadotte School and
other schools.

The presentaion will start by giving a brief
overview of the current Hypertext Markup Language (HTML), and the development
trends we are seeing today.
The talk will focus on one of these trends: style sheets. Web
publishers commonly request more influence over the presentation of documents,
and HTML is under constant pressure to add visual markup. Allowing publishers to
attach style to documents will enhance the aesthetics of the web, but visual
tags are not best right solution.
Using style sheets, authors attach style to existing HTML tags. A
simple style sheet might suggest that the headlines of a document are rendered
in blue on a white background. By attaching style (colors) to the structure of a
document (headlines), style sheets ensure device-independence and the
preservation of document structure. A style sheet can be stored separately from
the document it applies to, and it's easy to change the presentation of a
document by applying a different style sheet. Also, one style sheet can be
applied to many documents.
The talk will also discuss how style sheets relate to other
technologies, e.g. page description languages and multimedia.

FUNET begun piloting ATM among the first
organizations in the word in spring 1993. In the beginning emphasis was with
multimedia using direct ATM connections between workstations. In fall 1994
FUNET started to experiment with carrying normal IP traffic between ATM
connected routers. This lead in summer 1995 into production use of ATM in
FUNET's national IP backbone. The presentation describes the current

The topic of "security" in network systems
is so pervasive and multi-faceted that it is often difficult to make sense out
of it all. This introduction aims to define the components of network security
and describe their complex interrelation. Common security technologies, such
as cryptography and firewalls, are examined in terms of their objectives,
applications, and the threats motiviating their use. With this overview, it
should be easier to understand how the particular security systems fit
together.

In recent years, we have seen a rise in the number
of incidents, where intruders have succeded in seizing control of all the
machines on the network of an entire institution or company. This is to some
degree due to the proliferation of a range of tools, used by the so-called "hackers":
- Various programs exploiting send mail vulnerabilities
- The
internet sniffer and the potential danger of IP-spoofing.
As the
various services on the Internet, especially WWW, become more and more in demand
by companies and institutions, they are faced with a dilemma: For strategic
reasons they have to be connected to the internet, and for security reasons,
they are afraid to.
Therefore, secure ways to be connected to the Internet
are very much in demand. This speech deals with the tools and methodologies used
in making today's secure internet connections. The following topics will be
covered from a security point of view:
- The tools: COPS, Tiger, Tripwire,
SATAN
- Password quality: crack, passwd
- Network topology
-
Router configuration
- Packet-filtering firewalls
- Application-level
firewalls

The explosive popularity of the World Wide Web has led
to calls for increased security in this new environment. Numerous technologies
are being developed to address the need for strong authentication,
authorization and confidentiality systems in order to enable sophisticated use
of the Web and pave the way for WWW-based digital commerce.
This
presentation provides an overview of the issues, requirements and development
activity pertaining to security on the Web. After discussing some system
security concerns involved in using Web browser and servers, we examine a few
specific technologies for Web security, such as S-HTTP and SSL. We then
consider the relationship between these mechanisms and the many schemes
proposed for online digital payment, and finish with a look at directions of
future developments.

Allan F. Ottosen, (PBS A/S)
The Internet provides universal
access to a new and promising electronic marketplace, but secure and reliable
means of payment are vital if shopping on the net is to take off. Banks have for
years provided the payment means, e.g. credit and debit cards, for the existing
marketplaces. It is therefore a matter of high priority for the banks also to
satisfy the cosumers' and merchants' needs to make payment transactions in
cyberspace, but what is happening?
The presentation will focus on
discussing the following questions: What are the business requirements for
payment systems in cyberspace? What kind of payment systems are underway and how
might they evolve? Why is it important to support the achievement of a single,
open, non-proprietary standard for secure payment card transactions in
cyberspace?

Today the Internet offers vast resources of
free scientific information, available from preprint servers or electronic
journals, operated by the scientists themselves. However, even greater
information resources are waiting to enter the digital networking age. The
traditional scientific journals, published by learned societies or commercial
publishers and distributed by libraries, need reliable and attractive payment
systems in order to be offered via the networks. Likewise, the international
indexing and abstracting services that facilitate the access to
thesepublications need networked cost recovery mechanisms in order to migrate
from the proprietary online systems to the open network.The EU supported COPINET
project sets out to investigate and trial such payment systems that may meet the
requirements of publishers as well as libraries and end-users. The project
partners include the Institution of Electrical Engineers, a publisher of primary
scientific journals as well as abstract databases, MARI Computer Systems, a
software developer, andthe Technical Knowledge Center & Library of Denmark,
a distributor of scientific information to research and industry.The COPINET
trial system is based on a WWW server complex, able to support searching of the
abstracts database with automatic linking to the full-text archive. This
infrastructure is used for experiments withauthentication, charging, billing and
payment systems which can handleregistered as well as unregistered users. The
aim is to produce imple-mentation guidelines based on practical experiments with
a number of payment schemes, ranging from off-line invoicing to digital cash
transfer, and on feedback from publishers, libraries and end-users participating
in the project trials. The talk will focus on the user requirements and user
interface design issues rather than the technology components.

type operating system, from the ground up. How can this loose team of hackers
produce such high quality software, in the anarchistic world of the Internet?
In this talk, we will describe the "Linux approach" to
collaboration, exchangement of idea, development, test, and support across the
Internet.

In the annals of intercontinental Internet
connectivity, the cooperation between NORDUnet and the National Science
Foundation (NSF) ranks as one of the earliest and most successful
collaborations. From a 56 kbps connection from KTH to the NSFNET via JvNCnet in
1988 to a 24 Mbps share of the new 34 Mbps "huge Pipe" between the
U.S. and Sweden in 1995, NSF-NORDUnet networking has led the field. The upgrade
path has often been difficult because of funding limitations and implementation
delays, and most recently, we have encountered uncertainties about backup and
restoration. If we regard these as teenage growing pains, what kind of an adult
future might we anticipate? What are NSF's plans for follow-on high capacity
intercontental Internet services? The topics will be covered in light of the
replacement of the NSFNET Backbone service by commercial service providers under
a new architecture and the growing dominance of the U.S. Internet scene by
competitive service providers.

As many new networked services to identify,
access, and retrieve information resources have been established, the Internet
Engineering Task Force (IETF) has been interested in the integration and
coordination of information resources developments in the Internet. An
Integrated Information Architecture Plan (IIA) was written in September 1992 to
focus on how to integrate the many new services into a single coordinated
Internet information naming, discovery, and retrieval system. This presentation
provides a background of the IIA, explores the progress of the network
information services development in the IETF, and the IIA's future.

The Internet has been on an exponential growth curve
since about 1988. We are starting to see the side-effects of globalization and
use by segments of society that were not normally associated with the Internet
during much of its development since 1973. It is evident that the Internet is
becoming a business tool unlike anything else ever before. It combines aspects
of mass media with the personal interaction of telephone. It allows group to
interact and collaborate in ways not feasible before and it exploits the power
of computing to enable users to enhance their productivity.Of course, such a
pervasive and powerful phenomenon has its other unexpected side-effects. There
are many legal questions that this technology raises which will need to be
explored indepth for solutions. Intellectual property rights, freedom of speech,
libel/slander, harrassment and other matters of that kind are of concern, and
privacy and integrity of networked information raise technical and legal
questions.We are seeing some interesting social side-effects of the network
which may not have been anticipated, included an apparent increase in travel
induced by discoveries on the Internet. As we stand on the threshhold of a new
millenium, the Internet may be the escalator that takes us forward.
