Title: Network Virtualization and SDN/OpenFlow for Optical Networks - EU Project OFELIA

Network Virtualization, in addition to server and storage virtualization, will be the next important step for cloud computing and data center interworking. An important ingredient for the ability to perform network virtualization is the decoupling of data plane and control plane, and the availability of a centralized network control which enables network programmability though open Application Programming Interfaces (API). This is commonly referred to as Software Defined Networking, and OpenFlow is today the most prominent SDN protocol between a centralized controller and the network elements or between a virtualization visor and the controller. However, OpenFlow is still quite immature. As it developed from a packet-based campus environment, several concepts and features are missing for application in carrier class circuit or lambda-switched transport networks.

The EU Project OFELIA – "OpenFlow in Europe - Linking Infrastructure and Applications" offers a Pan-European testbed to the research community for conducting experiments in an OpenFlow-enabled wide-area network. Within OFELIA, the OpenFlow protocol is applied to and extended for the optical domain to support lambda switched ROADMs networks. In this paper the concepts and challenges of network virtualization for optical transport networks is presented, and the authors discuss, how SDN and specifically OpenFlow can be used to address some of these challenges. After an introduction of the OFELIA project, the network models and protocol extensions developed for OpenFlow in optical networks and experimentally verified in the OFELIA testbed will be presented, and key results will be highlighted.


Dr. Achim Autenrieth is currently Principle Research Engineer Advanced Technology in the CTO Office at ADVA Optical Networking, where he is working on the design and evaluation of multilayer transport networks, control plane, and software defined networking concepts. He received his Dipl.-Ing. and Dr.-Ing. degree in Electrical Engineering and Information Technology from the Munich University of Technology, Germany, in 1996 and 2003. Before joining ADVA Optical Networking in June 2010, he was with Siemens AG and Nokia Siemens Networks, where he was last working as Head of BCS R&D Innovations. Achim is a member of IEEE and VDE/ITG, he authored or co-authored more than 60 reviewed and invited scientific publications and he is technical program committee member of ECOC, DRCN, and RNDM.

Dr. Jörg-Peter Elbers received the diploma and the Dr.-Ing. degree in electrical engineering from Dortmund University, Germany, in 1996 and 2000, respectively. From 1999-2001 he was with Siemens AG – Optical Networks, last as Director of Network Architecture in the Advanced Technology Department. In 2001 he joined Marconi Communications (now Ericsson) as Director of Technology in the Optical Product Unit. Since September 2007 he is with ADVA AG Optical Networking, where he is currently Vice President Advanced Technology in the CTO office. Dr. Elbers authored and co-authored more than 60 scientific publications and holds 14 patents. His research interests include optical network architectures for core/metro/access, broadband optical access systems, robust & high speed optical transmission, optical system automation and programmability and optical/electronic communication network & node design.
