WSON RWA Framework
  • Describes wavelength switched optical networks (WSON), subsystems, models and associated processes. Emphasizing those aspects that are different from other technologies that utilize a GMPLS control plane.
  • Provide computation architecture options and a high-level information necessary for path computation (RWA).
    • Info draft provides details of information model: Routing and Wavelength Assignment Information Model for Wavelength Switched Optical Networks (draft-ietf-ccamp-rwa-info-03.txt)
  • Summarize implications to GMPLS routing and signaling, and to PCE protocols.
  • Does not address optical impairments

Possible Next Steps
  • Start finalizing for last call



  • Extend Framework draft to include signaling/routing for regenerators, OEO switches
    • Changes are detailed in “draft-bernstein-ccamp-wson-signal-00.txt”
    • Align with ITU-T terminology for optical signals: Optical Tributary Signals (G.959.1). (This terminology is also used in G.698.1 and G.698.2). Along with their parameters.
    • Update routing model to include “signal compatibility”
