Orchestration of Ethernet services in software-defined and flexible heterogeneous optical networks


The STRAUSS project aims to define a highly efficient and global (multi-domain) optical infrastructure for Ethernet transport, covering heterogeneous transport and network control plane technologies, enabling an Ethernet ecosystem. It will design, implement and evaluate, via large-scale demonstrations, an advanced optical Ethernet transport architecture. The proposed architecture leverages on software defined networking principles, on optical network virtualization as well as on flexible optical circuit and packet switching technologies beyond 100 Gbps. In this talk an overview of the STRAUSS project will be given and the proposed orchestration architecture introduced. The talk will then highlight current activities and first results of the project.


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 networks, control plane, and SDN 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. Achim is a member of IEEE and VDE/ITG, he authored or co-authored more than 75 reviewed and invited scientific publications and he is technical program committee member of ECOC, DRCN, and RNDM.

Preventive Start-Time Optimization Against Network Failure


This paper reviews research on preventive start-time optimization (PSO). PSO determines a suitable set of link weights in an open shortest path network at the network operation start time that can handle any link failure scenario preventively.PSO minimizes the worst-case congestion ratio in case of failure. PSO can avoid both unexpected network congestion and network instability. We formulate the original PSO problem as a mixed integer liner programming problem by extending the start-time optimization model and describe heuristic approaches. We also introduce mathematical programming models for the PSO variations. In addition, we expand PSO into generalized preventive start-time optimization (GPSO) to find a link weight set that balances both congestion ratios under no failure and the worst-case failure.


Eiji Oki is a Professor at The University of Electro-Communications, Tokyo, Japan. His research interests are network control, traffic engineering, network optimization, switching and routing in networks. He is a Fellow of IEEE and a Fellow of IEICE.


The University of Electro-Communications (UEC) dates back to the year 1918 when the Technical Institute for Wireless Communications was founded. It was then elevated to university status in 1949. UEC opens a variety of courses in communication Engineering, informatics, electronics, mechanical engineering, material science and computer sciences.

Network Reliability – the Role of Excellence in Network (Dai Davies)


Network resilience is often considered principally in the terms of the initial, static design. Whilst this is a vital element, the way that the network actually performs for its users, both in the short and longer term, are equally important, often neglected areas. This paper considers the importance of Network Operations in ensuring network reliability and resilience. It analyses the structures of Network Operations and explains how, in addition to resolving faults, excellence in Network Operations contributes to, improved performance, greater security and long-term maintenance of network reliability.


Dai Davies has degrees in Engineering and Computer Science from the University of Cambridge.  His initial career was as a development engineer in telecommunications at BT, working on projects in both voice and data communications. Following a subsequent period leading Business Development for the International division of BT, he returned to a more technical role in the area of Research Networking in 1991 when he became director of the COSINE project. The main objective of COSINE was to create a pan-European infrastructure to provide services for National Research and Education networks in Europe and globally. The project led to the creation of the organisation DANTE. Davies was a founding General Manager of DANTE, a post he held until 2011, when he stepped down to return to his engineering roots, working on projects for DANTE in the area of Future Internet developments.


Delivery of Advanced Network technology to Europe (DANTE) was established in 1993 to provide a corporate structure for the co-operation among European NREN’s to provide them pan-European and global services. Its principal activity is the operation of the pan-European research network GEANT. It has also a long and successful track-record and providing technical and organisational help in the establishment of similar organisations in other world regions most notably, Latin America, South East Asia and, most recently Africa.
