Multiple LSP routing network security for MPLS networking

In this paper, network security algorithms and control protocol enhancements for multiple label switched path (LSP) routing in multiprotocol label switching (MPLS) networks are investigated. Most of the former research on multiple-path routing has been focused on using multiple paths as a topology to improve the throughput and the robustness of data transportation over packet switching networks. The developed topology absorbs these benefits and extends the features to provide enhanced wide area network (WAN) security. The proposed multipath technology uses the MPLS networking topology to provide enhanced levels of protection against path information sniffing and deciphering.
