Abstract

Abstract

An LSP extension mechanism is proposed to decrease the signaling overhead and handoff delay and to eliminate the packet loss in MPLS based mobile IP networks. For the LSP extension mechanism, some loops may exist in extended LSP, and the criterion used for breaking down the extended LSP is not proposed. Aiming to these problems, this paper firstly gives a method to avoid forming loops in extended LSP. Then, a criterion, i.e. user information cost function and signal information cost function, are defined to breaking down the extended LSP, and the analysis is provided to calculate these cost functions. How to utilize the cost functions to break down the extended LSP is also discussed. The performance evaluation results denote that overhead of LSP extension mechanism can be decreased by breaking down the extended LSP according to the proposed criterion.
