GMPLS network and IP network/MPLS network Interworking

摘要

When the nodes that support GMPLS (Generalized Multi-Protocol Label Switching) are introduced to networks, the novel GMPLS nodes may connect to the networks consist of conventional IP/MPLS nodes that don't support GMPLS. In this case, the GMPLS nodes must interwork to IP/MPLS nodes. This paper addresses the GMPLS and IP/MPLS interworking architecture, and examples both routing and signaling aspects. This paper proposes novel interworking scheme. In this scheme, some nodes in GMPLS network are advertised to MPLS network for in understandable way for IP/MPLS nodes. MPLS LSP (Label Switched Path) is established through GMPLS LSP tunnel. We experimented LSP establishment in the network consists of IP/MPLS nodes and GMPLS nodes.
