     Methodology for Benchmarking MPLS Traffic Engineered (MPLS-TE)
                        Fast Reroute Protection

Abstract

   This document describes the methodology for benchmarking MPLS Fast
   Reroute (FRR) protection mechanisms for link and node protection.
   This document provides test methodologies and testbed setup for
   measuring failover times of Fast Reroute techniques while considering
   factors (such as underlying links) that might impact
   recovery times for real-time applications bound to MPLS Traffic
   Engineered (MPLS-TE) tunnels.
