Abstract
A method for realizing route forwarding in a network, including: establishing LSPs in a bearer network; setting an entrance label in the starting node of each LSP pointing to forwarding information of the LSP; a bearer control entity assigning a transfer path for the service flow and sending the information of all corresponding entrance labels of the transfer path to the ingress edge node of the transfer path; when the service flow needs to be forwarded, the ingress edge node puts the label stack into the data packet of the service flow to generate an MPLS exchange packet; and forwarding the MPLS exchange packet in the bearer network according to the label stack until the packet reaches the egress edge node of the transfer path. The present invention grants high compatibility to the network, minimizes the network investment, and reduces the difficulties in network implementation.
