<p>The present invention discloses a method for tunnel mapping involved with the field of the next generation network. The method of the present invention comprises: according to a service data stream resource information request received, selecting, by a transport resource control function entity (TRC-FE), a corresponding label switch path (LSP) tunnel, and after completing allocation of the service data stream, instructing a transport resource enforcement function entity (TRE-FE) to update a stream label mapping table; and completing, by the TRE-FE, the update of the stream label mapping table, and according to mapping information in the table, mapping the service data stream to the LSP tunnel designated. The present invention solves the problem that a mapping between a service data stream and LSP tunnel resource in a NGN based on MPLS-TE can't be implemented according to current standards, and fills a gap in implementation of resource allocation in a bearer network.</p> |
