A New Loop-Free LSP Extension Mechanism for Integration of Mobile IP and MPLS

A LSP extension mechanism is proposed for integration of mobile IP and MPLS to decrease the signaling o- verhead and handoff delay and to eliminate the packet loss. For the LSP extension mechanism, some loops may exist in extended LSP. This paper discusses this problem in detail and gives a method to avoid forming loops in extended LSP. The network resources can be saved and the packet delay can be decreased by this method.
