2. © 2010 MAINS Consortium WP1-Objectives for the reporting period Technoeconomic analysis to be reported in D1.2 (M15): The proposed MAINS architecture will be analysed under a technoecomic point of view in order to identify potential application scenarios in an operator network. Standardization activities to be reported in D15 (M15): One of the project objectives is the control plane standardization (e.g GMPLS extensions for sublambda granular networks). The main targeted SDOs are the Internet Engineering Task Force (IETF, in particular the Common Control and Measurement Plane and Path Computation Element Working Groups) and ITU-T SG15.

12. © 2010 MAINS Consortium WP1-Standardization at IETF Internet draft “Framework for GMPLS and path computation support of sub- wavelength switching optical networks” The IETF draft, which was fully prepared within MAINS project, discusses the framework for enhancements to the GMPLS architecture to control sub-wavelength switching optical networks. Main topics addressed in this framework are as follows: — Introduction to sub-wavelength optical networks: research and applicability scenarios — Sub-wavelength network resource control: control functions and time-scales, network resource modeling. — GMPLS implications: Impact on GMPLS signalling, sub-wavelength resources and labels, sub-wavelength traffic specification — Impact on GMPLS routing: sub-wavelength network resource availability — Route computation and sub-wavelength resource assignment scenarios: – centralized PCE and centralized sub-wavelength resource assignment – centralized PCE and distributed sub-wavelength resource assignment – distributed PCE and distributed sub-wavelength resource assignment

This data plane standardization work at ITU will pave the path for further control plane standardization activities in 2012.

14. © 2010 MAINS Consortium Next Steps in WP1 Exploitation Plan (M30) Use cases Business model Standardization activities MAINS contributions in the ITU will be mainly focused on the definition of a common terminology for existing sub-wavelength switching technologies Contributions to IETF will extend the GMPLS control plane extensions proposed in 2011 to the frequency domain
