Performance analysis of the reachability protocol for ipv6 multihoming

Abstract. There is ongoing work on the IETF aimed to provide sup-port for different flavors of multihoming configurations, such as SHIM6 for multihomed sites, multiple CoAs support in MIP for multihomed mo-bile nodes and HIP for multihomed nodes and sites. A critical aspect for all the resulting multihoming protocols is to detect failures and gain in-formation related with the paths available between two hosts. The Failure Detection and Locator Path Exploration Protocol (in short REAchabil-ity Protocol, REAP) being defined in the SHIM6 WG of the IETF is a good candidate to be included as a reachability detection component on protocols requiring this functionality. Performance study is performed by combining analytical estimations and simulations to evaluate its behavior and tune its main parameters
