EWSDN 2012 - European Workshop on Software Defined Networks

Software Defined Networking (SDN) is emerging as a promising architectural solution to support and foster innovation in telecommunication networks. Several switch/router vendors are “opening” their hardware, offering APIs to allow a “software defined” control of the networking operations. The vitality of the SDN approach is witnessed by the release of several SDN tools and development environments, most of which are open sourced.
OpenFlow
The OpenFlow specifications, now standardized by the Open Networking Foundation, can represent a key component in a SDN architecture, but the SDN scope and concept is much wider than the OpenFlow APIs. In particular there is the need of higher level SDN abstractions and higher level SDN APIs, as the ones that should be offered to applications (e.g. SDN “north-bound” interfaces).
European?
What makes an SDN workshop “European”? Traditional strengths of European research and development have been in optical transmission and wireless, especially cellular networks. The workshop emphasizes aspects of Software Defined Networks that come up when extending SDN 'beyond Ethernet'. In this regard, “European” does not mean that we restrict to a geographic scope, we welcome contribution and participation from all over the world.
Motivation
One goal of the workshop is to bring together industry and academia on the topics of SDN, in particular the workshop will feature an “industry forum”, i.e. a session with presentations of key industrial players (manufacturers, telecom operators, ...).
A special session will include presentation and discussion of the highest ranked proposals to the 2nd open call of the OFELIA project.
Contributions to the workshop
We are interested in both papers showing consolidated results and in position papers bringing up innovative ideas. We welcome contributions including, but not limited to, the following topics:
Optical extensions to OpenFlow, SDN
Wireless integration, characterization of wireless interfaces, flows, handover support
Evolved packet core, LTE support for OpenFlow
New controller architectures, Application Programmer's Interfaces, SDN “north-bound” interfaces
Higher level SDN abstractions, APIs, object models
New networking paradigms like Content or Information Centric Networks (CCN/ICN) and their relation with SDN
Carrier-grade SDN architectures and equipment
Network Virtualization techniques based on SDN
Practical experiments on OpenFlow / SDN based testbeds
Identification of use cases for SDN, SDN related business models
SDN frameworks and tools, SDN based equipment: controllers, switches, integrated development environment, testing and debugging environment
