Embodiment Construction
[0028] The present invention mainly does the following work: through the improvement of FRP and BRP resource reservation technology, a new resource reservation method applied to multi-layer multi-domain intelligent optical network and supporting service priority is proposed: priority-based domain The technical solution of IDRPBP is illustrated by the following example:
[0029] Set the network environment as image 3 As shown in , it is assumed that the boundary nodes of each control domain have the wavelength conversion capability. The source node of the client sends a connection establishment request, requesting to establish an LSP from the source node to a destination node in domain n through multiple control domains. According to the respective characteristics of different services passing through multiple control domains, each service is assigned a number from 0 to 7 to represent different priorities, among which 7 indicates that the service has the highest priority...
