GMPLS Superset of MPLS Unified control of diverse network technologies 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

Tunnel LSP: Example Labels distributed between specific end-points 15 35 47 15 92 Data flow 28 Ingress initiates LSP Request propagated to egress Egress responds with label Response propagated upstream to ingress
