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

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

Controlled Light Path
• Reuse of MPLS and IP Control
Data flow
λ2
– Ingress initiates light path setup
– Request propagated to egress
– Egress responds with lambda
– Response propagated upstream to ingress
