    • P-OTS: Don’t Forget About the Control Plane
      Control plane functions
      Automated LSP set up, tear down
      On-Demand provisioning
      Automated protection & restoration
      Link bundling
      Automated discovery
      Control plane benefits
      Reduced OPEX
      Facilitates network migration
      OAM negotiation
      Increased availability
      Quicker service set up time
      Reduced human errors
      New services
      Key application for service providers:
      ASON/GMPLS Control Plane

    • Multi-Layer Control Plane
      Multiple layers can include
      MPLS-TP transport service sublayer
      MPLS-TP transport sublayer
      TDM layer (ODU)
      WDM layer (OCh)
      GMPLS is common
      Carriers use only the layers needed
    • Multi-Layer Control Plane: Making it Work
      Client – Server model
      Common in our industry: see IETF, MEF, OIF UNI implementations
      Horizontal and vertical interoperability
      Source: OIF

      = TE Path
      More than just inter-area solution
      Lower CAPEX
      Optimal relocation of network intelligence
      Solves complex routing issues (WDM/OTN)
    • Summary
      Control plane has significant benefits
      Large demand by service providers
      P-OTS/OTN = Multi-layer Multi-layer control plane
      GMPLS is common across layers
      GMPLS standardized and well understood for years
      Inter-area and client-server considerations to be made
