GMPLS+IP/MPLS NODE AND IP/MPLS NODE

摘要

A network is realized having GMPLS and IP/MPLS mixed, in which anIP/MPLS node can be operated as is without replacing the IP/MPLS node with anodehaving a GMPLS function, even if the GMPLS and IP/MPLS are mixed. To matchwiththe protocol of the IP/MPLS node outside of a GMPLS cloud, the GMPLS+IP/MPLSnode (edge) establishes a PSC-LSP between GMPLS+IP/MPLS nodes (edge), uses thePSC-LSP as an IP/MPLS link from the viewpoint of the IP/MPLS node, andoperatessignaling of an MPLS-LSP establishment requested from the IP/MPLS.
