GMPLS Technology
GMPLS control plane supports:
- domain and unified service model
- overlay, augmented & peer control plane interconnection model (known as overlay and peer models)
GMPLS control plane architecture includes several extended MPLS-TE building blocks:
- Signalling Protocols: RSVP-TE and CR-LDP
- Intra-domain Routing Protocols: OSPF-TE and ISIS-TE
- Inter-domain Routing Protocol: BGP
- Link Management Protocol (LMP): new
TE-Routing enhanced scalability and flexibility
- Link Bundling (TE-Links)
- Generalized Unnumbered interfaces
- Extended Explicit Routing
