Capacity Sharing Workshop (CSWS) - Call for Contribution

Call for Contributions
NEC Laboratories Europe and the Institute of Communication Networks and Computer Engineering (IKR) of the University of Stuttgart invite you to a one-day workshop on the topic
Capacity Sharing
With the increasing amount of IP traffic in fixed and mobile access networks, the question how to share the available resources in a fair, efficient and demand-oriented way becomes more and more prevalent. With the variety of services one can find in today's Internet, the requirements in rate, data volume and latency differ strongly. To maximize resource utilization and, at the same time, provide satisfying performance to all users, application layer knowledge is needed. As different resource allocation and adaptation mechanisms already exist in MAC, transport and application layer, an integral consideration of the problem space is required.
In wireless networks, the problem is particularly relevant due to the inherently limited resources, which render a simple ?throwing bandwidth at the problem? solution impossible. Because large over-provisioning factors are economically unfeasibly, similar questions on capacity sharing also arise in fixed access networks, such as high bandwidth passive optical networks or cable networks.
The objective of this workshop is to bring together stakeholders of mobile and fixed access networks, the classic Internet world and of the application and transport community. We solicit presentations on the state-of-the-art, results of ongoing research, open issues, trends and new ideas. We are especially looking forward to (possibly provocative) visionary presentations to foster a lively discussion about how to face the upcoming challenges in the future mobile Internet.
