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.
