摘要： A source node, along with transmitting an optical path setup request, notifies towards a destination node available resource information related to itself, pre-assigns the available resources which its own node has notified. Each of transit nodes, along with relaying towards the destination node the optical path setup request which has been received from a previous hop node, notifies towards the destination node available resource information related to itself, and pre-assigns the available resources which each of their own nodes has notified. The destination node, along with reserving a resource which is to be used for setting up an optical path based upon an optical path setup request which has been received, transmits a resource reservation request towards the source node. The transit nodes and the source node actually reserve an available resource which has been pre-assigned, based upon a resource reservation request from a next hop node.

The multi-layer photonic network comprises a packet network which performs switching and transfer in packet units, and a photonic network comprising optical transmission lines and photonic switches, and which accommodates the packet network. The multi-layer photonic network also has a two layer structure of optical wavelength links (O-LSPs) and packet links (E-LSPs). The O-LSPs are constituted by the optical transmission lines and comprise optical wavelength switching capability (LSC) which is capable of switching in optical wavelength units and packet switching capability (PSC) which is capable of switching in packet units at both their ends. The E-LSPs include the O-LSPs and PSCs at both their ends. Each node includes a section for automatically establishing an O-LSP according to an establishment request for an E-LSP while taking account of path information including path cost, resource consumption, and traffic quantity.

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