  1. PCEP Extension for WSON Routing and Wavelength Assignment <draft-lee-pce-wson-rwa-ext-05.txt> Young Lee (Huawei) Ramon Casellas (CTTC) Fatai Zhang (Huawei) Cyril Margaria (NSN) Oscar González de Dios (Telefonica) Greg Bernstein (Grotto) IETF 86, Orlando, FL

  2. Updates from the last version Section 4.3 • Old: signal-compatibility-restriction ::= <MODULATION-FORMAT-LIST>|<FEC-LIST> • New: signal-compatibility-restriction ::= <Optical Interface Class List> • Encoding for <Optical Interface Class List> is referenced to WSON Encoding Draft Section 5 : Encoding of WA for Explicit Label Control (ELC) • For ELC, there should be a mechanism to indicate a set of labels (wavelengths) on each hop (i.e., in ERO Object). • Follows generalized GMPLS approach (instead of a separate encoding for WSON) by referencing <draft-margaria- ccamp-lsp-attribute-ero> and [WSON-Signaling]. IETF 86, Orlando, FL

  3. Summary & Next Steps • Aligned with Generalized Approach (GMPLS) as much as possible. • Most pending issueshave been addressed. • Ready to be adopted as WG document  IETF 86, Orlando, FL
