proposal: IP-Oriented QoS in the Next
Generation Networks: application to wireless networks (Half Day)
Emerging Internet Quality of
Service (QoS) mechanisms are expected to enable wide spread use of real time
services such as VoIP and videoconferencing. The "best effort"
Internet delivery cannot be used for the new multimedia applications. New
technologies and new standards are necessary to offer Quality of Service (QoS)
for these multimedia applications. Therefore new communication architectures integrate
mechanisms allowing guaranteed QoS services as well as high rate
communications.
The service level agreement with a mobile Internet user is hard to satisfy, since there may not be enough resources available in some parts of the network the mobile user is moving into. The emerging Internet QoS architectures, differentiated services and integrated services, do not consider user mobility. QoS mechanisms enforce a differentiated sharing of bandwidth among services and users. Thus, there must be mechanisms available to identify traffic flows with different QoS parameters, and to make it possible to charge the users based on requested quality. The integration of fixed and mobile wireless access into IP networks presents a cost effective and efficient way to provide seamless end-to-end connectivity and ubiquitous access in a market where the demand for mobile Internet services has grown rapidly and predicted to generate billions of dollars in revenue.
This tutorial covers to the
issues of QoS provisioning in heterogeneous networks and Internet access over
future wireless networks as well as ATM, MPLS, DiffServ, IntServ frameworks. It
discusses the characteristics of the Internet, mobility and QoS provisioning in
wireless and mobile IP networks. This tutorial also covers routing, security, baseline architecture of the inter-networking
protocols and end to end traffic management issues.

France. Between 1990 and 1995 he was a research engineer at WorldFIP Europe and
at Alcatel-Alsthom. He is a professor at the University of Haute-Alsace and
responsible of the Network and Telecommunication Research Group. His research
interests include QoS, wireless networks and high-speed networks. He was the Program
and Organizing Chair of the IEEE ICATM'98,
ICATM'99, ECUMN'00, ICN'01, ECUMN'02 and ICT'03, ICN’04 conferences and co-program
chair of ICC’04. Since 2000, he is a
Technical Editor of the IEEE Communications Magazine Editorial Board. He is the
secretary of the IEEE ComSoc Communications Systems Integration and Modelling
Technical Committee. He is senior member of the IEEE, member of many
international program committees and he has served as a guest editor for a
number of journals including Telecommunications Systems, IEEE Communications
Magazine and LNCS. He has organized and chaired several technical sessions and
gave tutorials at major international conferences. He is the author of 3 books
and 135 international publications in journals and conferences.
