Terminology for Benchmarking Link-State IGP Data-Plane Route Convergence
Abstract
This document describes the terminology for benchmarking link-state
Interior Gateway Protocol (IGP) route convergence. The terminology
is to be used for benchmarking IGP convergence time through
externally observable (black-box) data-plane measurements. The
terminology can be applied to any link-state IGP, such as IS-IS and
OSPF.
