Benchmarking Terminology for Protection Performance
Abstract
This document provides common terminology and metrics for
benchmarking the performance of sub-IP layer protection mechanisms.
The performance benchmarks are measured at the IP layer; protection
may be provided at the sub-IP layer. The benchmarks and terminology
can be applied in methodology documents for different sub-IP layer
protection mechanisms such as Automatic Protection Switching (APS),
Virtual Router Redundancy Protocol (VRRP), Stateful High Availability
(HA), and Multiprotocol Label Switching Fast Reroute (MPLS-FRR).
