Scope and Goal

Self-organizing Service Overlays and Network Virtualization Architectures for Service Provisioning and Data Management


A rapidly changing application landscape poses new challenges to the Internet infrastructure. On the one hand, new applications call for in-network support of specific communication services, e.g., group communication or QoS support. On the other hand, huge amounts of data, e.g., generated by users in a Web 2.0 fashion or collected by network-enabled appliances, ambient technologies, or sensors in a future "Internet of Things", must be managed. Mobility of users and devices increases due to new access networks such as LTE and WiMax and requires migration of both services and data. Upcoming exhaustion of IPv4 adresses and introduction of IPv6 increase the protocol heterogeneity for such scenarios, thus complicating connectivity for such applications.  Recent advances in network virtualization and self-organizing service overlays provide appealing solutions to trim the Internet for these requirements. However, despite of the rapid progress in both areas they only face limited deployment in real-world applications. To bridge the gap between conceptual work and real-world deployment, challenges and requirements must be revisited from the application's point of view.

This workshop offers an opportunity to discuss challenges and requirements with respect to building network architectures enabling flexible service provisioning and data management form the viewpoint of practitioners and users. A special focus lies on the requirements that arise from different application scenarios in such a context. Questions in this context might be: What issues in the Internet have to be solved for enabling such future applications? What kind of support from the network is required? Which supporting services in the network would be helpful?
