INTER-LAYER TE LINK RESOURCE MANAGEMENT METHOD FOR FA-LSP OF MULTI-LAYER TRANSFER NETWORK

摘要

PROBLEM TO BE SOLVED: To provide an inter-layer traffic engineering (TE) link resource management method for a forwarding adjacent-label switching path (FA-LSP) in a multi-layer transfer network.

SOLUTION: The disclosed method includes steps of: searching for a connection route available for an inter-termination route of a first layer, in a second layer, when the first layer requests inter-layer call setting for the second layer; setting a connection route available for the inter-termination route to FA-LSP; and registering the FA-LSP to the first layer and setting the FA-LSP to a TE-link for the inter-termination route.
