Stefano Vissicchio and Olivier Tilmans, together with their co-authors, Laurent Vanbever (ETH Zurich) and Jennifer Rexford (Princeton University) have received the best paper award at SIGCOMM 2015 for their paper entitled Central Control Over Distributed Routing that demonstrates how it is possible to efficiently construct SDN-like paths in a traditional network running OSPF.

Hybrid Software Defined Networking

Mon, 07/06/2015 - 18:42 by Stefano Vissicchio • Categories:

Software Defined Networking (SDN) promises to ease design, operation and management of communication networks. However, SDN comes with its own set of challenges, including incremental deployability, robustness, and scalability. Those challenges make a full SDN deployment difficult in the short-term and possibly inconvenient in the longer-term.
We explore effective hybrid SDN architectures that combine SDN with a more traditional networking approach based on distributed protocols. In a number of use cases, hybrid SDN architectures combine the strengths of traditional and SDN approaches, mitigating their respective limitations. As such, they provide incentives to (partially) transition to SDN, and can be appealing even as long-term design points.
