9. 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

10. Tunnel LSP: Example Labels distributed between specific end-points 1535 47 15 92
Data flow 28
Ingress initiates LSP
Request propagated to egress
Egress responds with label
Response propagated upstream to ingress

11. Controlled Light Path Reuse of MPLS and IP Control λ5 λ8 λ2
Data flow λ8
Ingress initiates light path setup
