GMPLS
  • Superset of MPLS
    • Identical concepts, mechanisms, protocols
      • IP-based, reuse existing stable/tested/battle-hardened protocols
    • Expands the concept of a “label”
      • In MPLS, a label ties a packet to a flow
      • In GMPLS, labels can identify TDM streams (SONET/SDH), Wavelengths (DWDM), Fibers (OXCs), as well as packet flows
  • Unified control of diverse network technologies
    • One set of concepts to learn, tools to deploy
      • LSPs, labels, signaling, routing, path computation
    • Manage different types of flows using single set of tools
      • Same provisioning methods for IP and optical networks
    • Lessons learned from MPLS deployments
      • Bidirectional LSP setup, support for out-of-band communications, etc
