Abstract: This
tutorial provides a comprehensive analysis of broadband networking technologies
with focus on network, service, and policy management. The broadband coverage
includes access, metropolitan, and high-speed multimedia backbone networks.
Current and emerging underlying optical transport and networking technologies
that compose broadband networks are evaluated for their functionality and
performance: WDM/DWDM, POS, Resilient Packet Rings, 10 Gigabit Ethernet are
analyzed along Gigabit Ethernet, xDSL, Cable modem, Wirelesss access, and
Wireless metro. The tutorial also includes analysis and evaluation of
management platforms/systems and associated management applications used in
commercial off-the-shelf products that provide broadband network and service
management.

17:30 Tutorial Session 2
Peter Altenbernd, Siemens Business Services,
Simon Schneider, Nokia Research Center, Michael Ditze, Paderborn
University/C-LAB
Abstract: The goal of this full day tutorial is to
give a broad overview of QoS aspects for multimedia applications in modern
wireless networks, focusing on UMTS and WLAN (IEEE 802.11) technologies as well
as heterogeneous combined approaches. Hence, it will introduce video streaming
compression techniques as a core component for multimedia premium services and
identify respective QoS parameters. The term QoS will be defined and Mobile IP
along with respective QoS models for network traffic control (Differantiated
Services, Integrated Services) and real-time information processing (real-time
systems, real-time scheduling) will be introduced. The main part of the
tutorial will examine how these models are currently adapted to 3G and WLAN
networks. The QoS concepts and architectures that will enable reliable premium
multimedia services, are covered. Therefore, it will also give a broad overview
of the relevant principles and architectures of UMTS and WLAN from both, the
industrial and research point of view. It will also try to answer some basic
questions of why and where UMTS and wireless local area networks can be used
and whether UMTS and WLAN are competing or complementary technologies. By
featuring two presenters with industrial background from leading-edge companies
Nokia and Siemens and one presenter with academic background from Paderborn
University, this tutorial addresses industrial practical topics complemented by
scientific research background. The target audience for this tutorial includes
both interested academics as well as technology decision makers from the
Telecommunications and Service Provider business, who want to gain deeper
understanding about QoS aspects of future wireless services.
Biography: Michael Ditze
(Paderborn University/C-LAB) has studied Computer Science and Economics at the University of Paderborn, Germany and
the University of New South Wales in Sydney, Australia (1997). Since he joined
C-LAB in 1998, a joint collaboration between the university and Siemens
Business Services, he has been doing practical industrial research in the field
of real-time networking systems and media processing (QoS) within EU funded
projects (Roxy, East). Michael has published 5 papers on this topic during the
last two years with one filed patent. He is currently preparing his PhD that
addresses adaptive scalability of video content in heterogeneous wireless
networks. He is further responsible for EU project acquisition and hence
familiar with the state of the art in the addressed technologies. Having taken
courses on English technical writing and presenting at Oklahoma State
University, he also offers commercial 2-day media processing tutorials on behalf

Albert M. K. Cheng, University of Houston, USA
Abstract: Multimedia and real-time systems are becoming
increasingly popular in a variety of applications. These applications include
group collaboration, remote medical diagnosis/treatment, conferencing systems,
on-demand video services, and distance/remote sensing, learning, and
monitoring. One major requirement for the implementation of such systems is the
efficient transmission of multimedia information (video, image, audio, text)
over a communication or computer network. Another major requirement is the
bounded-time access and storage of multimedia information. Current image (JPEG)
and video (MPEG) transmission techniques using precise or progressive
algorithms work well if sufficient processing power, network bandwidth, and
transmission time are available, but do not adapt properly to a reduction in
one or more of these resources. A precise algorithm must be executed in its
entirety before an output can be produced whereas the execution of an imprecise
algorithm can be ended at any time prior to normal completion and a usable
output can still be produced. Furthermore, the correctness of an imprecise
algorithm is monotone increasing. The more resources such as time are spent in
the imprecise algorithm's execution, the more accurate is the obtained output.
However, current transmission algorithms are not in the proper imprecise form
and must be significantly modified to implement the imprecise approach. This tutorial presents an application of
imprecise computation techniques to yield a balanced tradeoff between the
quality of the multimedia information transmitted and the available resources
for transmission in a networked environment. It also describes real-time
scheduling and routing techniques for networks with multimedia applications.
Proxy caching for web servers are also discussed. Then the tutorial evaluates
and assesses the practicality of the available techniques and tools for
building the next generation of real-time and multimedia networking systems.
Topics covered include the real-time aspects of multimedia systems; and the
analysis and verification techniques/tools based on schedulability analysis,
model checking, Statechart/Statemate, Modechart, timed automata, timed Petri
nets, process algebra, real-time temporal logic, and semantic rule-based
analysis.

12:30 Tutorial Session 4
Sandeep Chatterjee, FoundationalNet, Inc.
Abstract: The next stage in the evolution of enterprise applications will be based
on Web services. Web services are pieces of application functionality that are
exported through a set of standard application programming interfaces (APIs),
and allow applications to be constructed by locating and binding to the
exported functionality. More interestingly, multiple Web services can be
coordinated together in unique combinations in an Internet application to
implement value-added services for users. In this tutorial, we describe the
design, development, deployment, and maintenance of Internet applications based
on Web services. We also describe the emerging mobile Internet environment, the
unique issues inherent to these environments, and the challenges in developing
mobile applications based on loosely coupled Web services. In addition to a
broad coverage of the fundamental topics, industry standards, and technologies
(e.g., Java, J2EE, application servers, XML, SOAP, WSDL, UDDI) underlying the
development of Web services and applications based on Web services, the
tutorial will provide practical, step-by-step instruction for the development
and deployment of enterprise-class Web services and applications based on
standard Java 2 Enterprise Edition (J2EE) application servers and SOAP servers.
We also touch on .Net technologies in support of enterprise Web services.

17:30 Tutorial Session 5
Towards Self-Manageability through Dynamic Policy-driven Control in Distributed Systems
Petre Dini,
Cisco Systems, Inc.
Abstract:
Enterprises and small businesses are increasingly evaluating their outsourcing
options, and looking for a range of converged voice, video and data services.
As the converge occurs, the challenges of operating and managing an integrated
network intensifies. A resilient, flexible operational infrastructure becomes
the critical success factor in offering a granular and subscriber self-managed
portfolio. The tutorial will focus on several of the operational challenges of
a "policy-driven self-management", and offer a strategy, vision, and
concrete policy-enabled solutions toward adaptive and self healing networks of
the future. Emphasis will be given to the increasing function of the
"programmable layers, a policy-enabled management and service paradigm for
enabling network and service convergence, feature interaction free, and robust
through failure-avoidance. The tutorial will gradually introduce the topics in
four steps.
