17. ContractAmmendment • A contact amendment was requested and approved in order to increase project duration in 3 months. • This time extension would enable : • to organize a workshop at ECOC • extend standardization activities within the project. • MAINS Description of Work (DoW) was updated according to the project extension.

18. Concertationactivities • MAINS is actively participating in the CAON and Concertation meetings organised at programme level relating to the ICT Future Networks area. • Juan Fernández-Palacios is co-chair of the CAON (Convergent Access and Optical Networks) cluster where is coordination the standardization activities carried out within the cluster. • Furthermore, MAINS has also contributed to NEXT!WORK and CAON white papers providing its vision on metro network evolution.

Collaboration activities between STRONGEST and MAINS are focused on control plane interworking issues between GMPLS subwavelength domains implemented in MAINS and multilayer L2/WSON GMPLS domains implemented in STRONGEST. • MAINS have organized two workshops in collaboration with other projects during this period: • ONDM 2011 workshop about “Network Control Plane Evolution”. This workshop was done in collaboration with SRONGEST, GEYSERS and ETICS • Joint MAINS and GEYSERS ECOC workshop on Convergence of Optical Networks and Clouds.

20. Conclusions and nextsteps • Data and control planedesignand implementationactivitiesactivitiesare almostcompleted • Main activities to be carried out during the rest of the project can be summarised as follows: • Exploitation Plan Technoeconomicanalysis • Standardization • Implementation and Demonstration • MAINS implementation activities in 2012 will initially focus on creating and establishing a TSON network transport testbed. • TSON testbed will be interconnected with OPST ring (Intune NXT Beta nodes) to create the MAINS multi-technology multi-topology data plane testbed. • The testbed will be used to evaluate the end-to-end performance as well as validate different service scenarios (e.g. Virtual PC, UHD video). • Integration/interfacing of sub-wavelength enabled GMPLS control plane with the SLAE (Sub-Lambda Assignment Element) as well as the OPST and TSON nodes will be carried out. • The GMPLS control plane together with the SLAE will be used to provide dynamic control and provisioning of sub-wavelength services over the interconnected OPST-TSON transport network.
