Workshop on QoS and Traffic Control 7-9 December 2005 Ecole Normale Supérieure, Paris

Workshop Description

The accelerating trend towards network convergence for both services and technologies is bringing back to the fore the crucial issues of quality of service and cost-effective traffic control. How can the so-called triple-play of voice, video and data services co-exist and share resources in the access and core networks? To what extent can we create the same qualities of service in fixed and mobile networks allowing seamless integration? How can the network allocate resources to meet the terms of Service Level Agreements?

To answer questions like these depends on a sound understanding of the key networking mechanisms of congestion control, traffic management and traffic engineering. It is therefore particularly opportune to organize the present workshop on the design, modelling and performance evaluation of these mechanisms. It will allow us to highlight key issues, appraise current understanding and highlight those areas in need of further research. The workshop will focus on topics covered by the Euro-NGI work packages in Joint Research Activity 2 including the following:

• congestion control protocols • active queue management and scheduling • realizing differentiated qualities of service • flow-aware networking • traffic matrix inference • constraint-based routing

• bandwidth sharing and fairness issues • impact of pricing on congestion control and QoS • admission control • SLA management • intra- and inter-domain traffic engineering • adaptive load-sensitive routing

Specific attention will be paid to QoS and resource management issues in wireless and spontaneous (ad hoc and sensor) networks:

• congestion control over wireless links	• QoS and service differentiation in WiFi, WiMax
• engineering multiservice cellular networks (GPRS, UMTS,...)	• routing and traffic control in ad hoc and sensor networks
• cross-layer issues

Presentations at the workshop will be given by members of Euro-NGI and by a number of invited experts in the domain. The in-network presentations will be chosen on the basis of extended abstracts submitted to the technical programme committee according to the call for presentations. The intention is to create a balanced programme covering the scope of Euro-NGI research in the above areas and presenting the most interesting results obtained.
