IFIP -The International Federation for Information Processing
IFIP was founded in 1960 under the auspices of UNESCO, following the First World
Computer Congress held in Paris the previous year. An umbrella organization for societies
working in information processing, IFIP's aim is two-fold: to support information
processing within its member countries and to encourage technology transfer to developing
nations. As its mission statement clearly states,
IFIP's mission is to be the leading, truly international, apolitical organization which
encourages and assists in the development, exploitation and application of information
technology for the benefit of all people.
IFIP is a non-profitmaking organization, run almost solely by 2500 volunteers. It operates
through a number of technical committees, which organize events and publications. IFIP's
events range from an international congress to local seminars, but the most important are:
• The IFIP World Computer Congress, held every second year;
• open conferences;
• working conferences.
The flagship event is the IFIP World Computer Congress, at which both invited and
contributed papers are presented. Contributed papers are rigorously refereed and the
rejection rate is high.
As with the Congress, participation in the open conferences is open to all and papers may
be invited or submitted. Again, submitted papers are stringently refereed.
The working conferences are structured differently. They are usually run by a working group
and attendance is small and by invitation only. Their purpose is to create an atmosphere
conducive to innovation and development. Refereeing is less rigorous and papers are
subjected to extensive group discussion.
Publications arising from IFIP events vary. The papers presented at the IFIP World
Computer Congress and at open conferences are published as conference proceedings, while
the results of the working conferences are often published as collections of selected and
edited papers.
Any national society whose primary activity is in information may apply to become a full
member of IFIP, although full membership is restricted to one society per country. Full
members are entitled to vote at the annual General Assembly, National societies preferring
a less committed involvement may apply for associate or corresponding membership.
Associate members enjoy the same benefits as full members, but without voting rights.
Corresponding members are not represented in IFIP bodies. Affiliated membership is open
to non-national societies, and individual and honorary membership schemes are also offered.

Preface
SmartNet'2000 is the sixth in a series of conferences on Intelligence in
Networks started by IFIP TC-6 Working Group 6.2 (Broadband
Communications), the events being a preceding Workshop on IN,
Lappeenranta (August 1994), the Working Conference on IN, Copenhagen
(August 1995), the Workshop on Broadband Network Intelligence
(WBNI'96), Espoo (November 1996), and the Conference on Intelligent
Networks and Network Intelligence (2IN97), Paris, (September 1997). The
series now belongs to the area of Working Group 6.7 (Smart Networks) with
previous conferences held in Moscow (Smartnet'98, February 1999,
postponed from 1998) and Bangkok (Smartnet' 99, November 1999). The
conference series has been established to be a forum for discussion of issues
related to the development of intelligent capabilities in telecommunication
networks. These topics generally include the creation, distribution, and
management of telecommunication services in narrowband networks,
broadband networks as well as mobile networks.
In the world of telecommunications, the ultimate goal is to provide
network customers with a variety of versatile services. Today flexibility is a
key design issue for emerging network architectures and service platforms in
order to be able to adapt instantly to changing customer service demands. In
contrast to the traditional way of implementing intelligent network services
in centralized service nodes which control the switching nodes of the
transport network using a dedicated signaling network, the current trends are
towards implementing distributed network intelligence, eventually supported
by mobile software agents and active networks. The basic idea of these last
two directions is the movement of service code directly to network switching
nodes and network control nodes as well as between all kind of applications
in the end systems. In addition, this service code movement should be
possible in a highly dynamic manner, thus allowing automated, flexible, and
customized provision of services in a highly distributed manner. This would
enable better service performance as well as optimized control and
management of the transport network capabilities.
Two enabling technologies are crucial in open, active and programmable
networks: programmable network nodes providing flexibility in the design of
connectivity control applications, and platforms for mobile software agents
allowing dynamic downloading and movement of service code to specific
network nodes. The intelligence inside the service agents permits distributed
configuration and provision of service intelligence inside the network,
x
thereby relaxing the load of service control and management systems as well
as that of the signaling traffic.
Research in networking and flexible service platforms is exploring ways
in which network nodes and end systems may be dynamically programmed
by network operators, their customers, and third parties. The advantages of
customized routing and communication protocols, dynamic allocation and
reallocation of resources among service classes, flow-specific information
processing in network nodes, and fast and adaptive service creation are
extremely attractive, but the basic conditions of security, reliability, and
performance still require considerable efforts.
The proceedings of SmartNet'2000 reflect research activities all around
the world for achieving these goals. The discussed topics in the conference
are on telecommunication service architectures, flexible service creation,
service distribution and management, security services, advanced
intelligence in networks, application of agent technology for routing and
network control, performance monitoring, network management, QoS
management, mobility management, interactive multimedia as well as
dynamic switching and active networks.
Many persons have contributed to make this conference a success. I
would like to thank the members of the organizing and technical committees,
the authors and reviewers, the Vienna University of Technology, the
sponsors of the conference, and the staff of the Institute of Communication
Networks. Particular thanks are due to Johanna Pfeifer of my institute and
Dr. Reda Reda of Siemens Austria for their very successful and highly
appreciated organizational support.
