Abstract: The multihoming is one of the effective ways to defeat path failure and increase the reliability of site network service. However, limited by the hCP/IP naming and addressing architecture, the mulithoming has not been well deployed. One of the most important reasons is the problem of semantic overloading of IP address. Current IP address hasdual semantic functions, which indicates both the network node' s routing locator and its endpoint identifier. We proposed a sit mulithoming path failure recovery mechanism(LISA-Recovery) based on the LISA(Locator Identifier Split Architecture) architecture. The results of simulation test prove that LISA-Recovery can effectively detect the path failure and performance reduction, and make a rapid path switch. It will greatly strengthen the reliability of application service. We also gave a theory analysis of the bandwidth overhead brought by LISA-Recovery. It shows that the bandwidth overhead is very small and our approach is feasible.
