This paper characterizes analytically the performance of REAchability Protocol (REAP), a network layer end-to-end recovery protocol for IPv6. REAP was developed by the IETF SHIM6 Working Group as part of its
multihoming solution. The behavior of REAP is governed by a small number
of parameters: three timers, a simple characterization of the
application traffic, and the communication delay. The key figure of
merit of REAP performance is the time to recover from a path failure as
seen by the upper layers, figure that cannot be trivially obtained,
despite the apparent simplicity of this reachability protocol. In this
paper we provide upper bounds for the recovery time of REAP for
different deployment scenarios, applying these analytical results to two
interesting case studies, TCP and VoIP traffic.
