Evaluation of IP Fast Reroute Proposals

Abstract— With the increasing demand for low-latency applications in the Internet, the slow convergence of the existing routing protocols is a growing concern. A number of IP fast reroute mechanisms have been developed by the IETF to address the issue. The goal of the IPFRR mechanisms is to activate alternate routing paths which avoid micro loops under node or link failures. In this paper we present a comprehensive analysis of these proposals by evaluating their coverage for a variety of inferred and synthetic ISP topologies.
