We have published a short report of last week's ICN workshop at SIGCOMM. It was a really interesting event, with excellent papers and presentations and an inspiring panel discussion.

The two selected best papers are:

Ali Ghodsi, Teemu Koponen, Jarno Rajahalme, Pasi Sarolahti and Scott Shenker; Naming in Content-Oriented Architectures

Diego Perino and Matteo Varvello; A Reality Check for Content Centric Networking

You can download them and all the other papers at the workshop website.

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.

NEC Laboratories Europe and the Institute of Communication Networks and Computer Engineering (IKR) of the University of Stuttgart are organizing workshop on Capacity Sharing to address these topics. 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. Topics of particular interest include, but are not limited to

• Application-layer adaption for mobile services
• Transport layer solutions and possible interactions with cellular/fixed access networks
• Context-aware resource allocation & cross-layer adaptation
• QoE and fairness definitions, metrics and evaluation
• Data traffic characteristics in fixed and mobile Internet
• Economic aspects on capacity sharing and business models
• Similarities and differences of capacity sharing in mobile and fixed access networks
• Related standardization activities and projects

The workshop takes place in Stuttgart on Thursday, October 13, 2011, and is organized by Mirja Kühlewind (IKR), Christian Mueller (IKR) and myself.

Information-Centric Networking (ICN) is one of the significant directions of current networking research. In ICN, the principal paradigm is not end-to-end communication between hosts - as it is in the current Internet architecture. Instead, the increasing amount of content that must be distributed requires alternatives: Architectures that work with information objects as a first-class abstraction; focusing on the properties of such objects and receivers' interests to achieve efficient and reliable distribution of such objects. Such architectures make in-network storage, multiparty communication through replication, and interaction models such as publish-subscribe generally available for all kinds of applications, without having to resort to dedicated systems such as peer-to-peer overlays and proprietary content-distribution networks.
