Session 1A

Content Creation

and Learning in Virtual Universities

Chair:

Leif Laaksonen, Center for Scientific Computing, Finland


Universities create new knowledge through research and distribute it through teaching. Traditionally,
both of these activities have been conducted insid
e the university walls. However, research can only
be conducted successfully through collaboration and the concept of life long learning is putting new
demands on the information content itself and the way it is distributed.


Computer networks enable both

scientists and students to access new sources of information,
independent of time and place. Whole courses can be put on the network and teachers reached through

videoconferencing; research groups can join together in more powerful virtual research group
s using
scientific equipment over the network; and departments can join together to create new virtual research
centres. This session will include a presentations which address the technical, organisational and
pedagogical challenges involved in content c
reation and learning in virtual universities.

Improving the Quality of Service (QoS) guarantees will be the major challenge of tomorrow’s Internets
and Intranets. Several approaches were proposed by t
he IETF, ranging from reservation

'Telematics for Research' Open Seminar (Part 1)

Chair:

Karel Vietsch, TERENA


In the ‘Telematics for Research’ sector of the Fourth Framework Programme, the European Uni
on
currently supports 12 research and development projects addressing the needs of users in the European
research community. These projects are working on diverse telematics applications covering many user
disciplines. Topics include videoconferencing to
ols, collaborative working using the Web, security and
the underlying network infrastructure.


In this Seminar, which is also open to persons who have not registered for the conference, a number of
the ‘Telematics for Research’ sector projects will present

their most recent results. During the
conference, some of the projects will also demonstrate the services and software that they have
developed in the conference exhibition area.

Remote Control

Chair:

Petter Kongsha
ug, UNINETT, Norway


This session describes how networks can be efficiently used to control facilities, objects, etc. remotely.
Currently the most suitable graphical interface, or at least the most easy to implement, is a Web
-
based
interface. Specific or

generic remote control applications can thus enable many activities to be
performed from remote sites, and implement what some people call "tele
-
presence".

WWW Tools

Chair:

Claudio Allocchio,
INFN
-
GARR
, Italy


For some time, World Wide Web (
WWW) browsers have gained a new role in the network, which
extends beyond their original scope. In fact, many new tools and applications are developed using the
WWW browser as a common Graphical User Interface (GUI) for the application itself. An obvious

advantage of this approach is that the application does not require a specific “client” installed on the
user’s computer. This session is dedicated to presenting new tools which interact with the WWW
service itself, including searching WWW information an
d interacting with the WWW service via the
WWW interface.

IP Technology Update

Chair:

Ton Verschuren, SURFnet, The Netherlands


Compared to the recent rapid development in application

level technologies, the underlying protocols of

the Internet might appear to be developing slowly.

Recently, however, a new era of deployment has
begun and this session will attempt to look at some of the key developments in the very fabric of the
Internet itself which have come to fruition over the last year or so, including the emergence of the
“Mid
dleware” concept for supporting applications; and the wide
-
scale deployment of replication and
caching services.

Video transmission is an integrated part of distance learning and videoconferencing. However, the
availability of a broad range of network bandwidths has introduced a spectrum of transmission
protocols and CODECs to sustain an acceptable video qual
ity and frame rate. This session will deal
with the technical aspects and challenges involved in low

bit rate video transmission
in uni

speed switching and routing functions. The session will deal with LAN
switching and Ethernet switching; when to switch and when to route;
and how do the different
techniques scale when we move from Gigabit to Terabit?

Session Sponsored by Elsevier Science


The development of new security products, services and infrastructures is a great enabler for electronic
applications that were previously not possible on the I
nternet. Previous concerns about the integrity
and confidentiality of data transfer, and the authentication of remote users, can now be overcome using
the latest encryption techniques. This session will look at a range of recent developments in this area
,
introducing some of the new applications that have now become possible thanks to the introduction of
enhanced Internet security.

IP Telephony

Chair:

IP has become the preferred protocol
not only in academic but also in public and private networks. The
deregulation of telecommunications is leading to a fundamental restructuring of the industry and packet
switched data networks will soon be taking market shares from circuit switched voice
telephony. This
session will take a look at some issues surrounding IP Telephony including: which standards ensure
speech quality in Voice over IP (VoIP); what experiences are there in running VoIP; and what new
services in VoIP, multimedia and mobility w
ill be provided by the telecommunications suppliers?
