  1. OSPF Extensions for WSON and General Constraints draft-zhang-ccamp-rwa-wson-routing-ospf-03.txt draft-ietf-ccamp-wson-signal-compatibility-ospf-01.txt Fatai Zhang (zhangfatai@huawei.com) Young Lee(ylee@huawei.com) Jianrui Han(hanjianrui@huawei.com) Greg Bernstein (gregb@grotto-networking.com) Yunbin Xu (xuyunbin@mail.ritt.com.cn) 78th IETF – Maastricht Netherlands, July 2010

  2. Current Document Flow WSON Information Model (WG draft) Informational RWA WSON Encode (WG draft) General Constraint Encode (WG draft) Standards Track RWA WSON Routing (individual draft) WSON Signal Compatibility OSPF (WG draft) Standards Track OSPF Specific 78th IETF – Maastricht Netherlands, July 2010

  3. B Node LSA Connectivity Matrix A A C C WDM links LSAs WDM links LSAs Ingress ports Egress ports D D OEO pool LSA OEO pool LSA Reconciliation with Peloso Draft One connectivity matrix for both optical and OEO connectivity Figure from Pierre Peloso Keeps track of wavelengths on these internal links 78th IETF – Maastricht Netherlands, July 2010

  4. Reconciliation with Peloso Draft (cont.) Ingress ports Egress ports Connectivity Matrix A A C C D D General Constraint OSPF extensions OEO Ingress Matrix OEO Egress Matrix OEO pool LSA OEO pool LSA Info model & encoding updated to include Wavelength availability info. WSON signal compatibility OSPF 78th IETF – Maastricht Netherlands, July 2010

  5. Next Steps • WSON Signal Compatibility OSPF • Update to reflect latest changes to RWA WSON encoding draft • RWA WSON routing • Rename from: “OSPF Extensions in Support of RWA in WSONs” to: “OSPF Extensions for General Network Element Constraints” • Adopt as Working Group Document • Clean up text to describe “generality” and alignment with general constraints encoding 78th IETF – Maastricht Netherlands, July 2010
