GMPLS TE-Routing Extensions
GMPLS based on IP routing and addressing models
IPv4/v6 addresses used to identify PSC and non-PSC interfaces
Re-using of existing routing protocols enables:
- benefits from existing intra and inter domain traffic-engineering extensions
- benefits from existing inter-domain policy
To cover SDH/Sonet, G.709 OTN transmission technology GMPLS-TE defines technology dependent TE extensions
Increasing scalability using Link bundling and unnumbered interfaces
LSP Hierarchy (and region) through Forwarding Adjacency concept (FA-LSP)
