1 A Yang Data Model for WSON Optical Networks 1CCAMP IETF 103 Bangkok draft-ietf-ccamp-wson-yang-15 Y. LEE, D. DHODY, A. GUO (HUAWEI) V. LOPEZ (TELEFONICA) D. KING (U. OF LANCASTER) B. YOON (ETRI) R. VILALTA (CTTC)
2 Updates Since IETF 100 2CCAMP IETF 103 Bangkok Created Github to manage all L0 models aross WSON & Flexi-grid: Introduced a new ietf-layer0-types module ( /ietf-layer0-types% yang ) to define groupings that are used to both WSON and Flex-grid modules, e.g., Node types, Application code based on ITU-T G.698.2, Wavelength Assignment Policy. Client types, etc. Complete augmentation of TE-topology model is now available; in particular, on all modules that require WSON specific labels and bandwidth types.

9 Current Status & Next Steps 9CCAMP IETF 103 Bangkok The draft depends on te-tunnel model stability, which should be soon attained. Other than the dependency of te-tunnel model, the model is ready for YANG doctor s review and WG LC.
