Abstract

This document discusses the applicability of various tests for measuring single router control plane convergence, specifically in regard to the Open Shortest First (OSPF) protocol. There are two general sections in this document, the first discusses advantages and limitations of specific OSPF convergence tests, and the second discusses more general pitfalls to be considered when routing protocol convergence is tested.

Abstract

   This document discusses the applicability of various tests for
   measuring single router control plane convergence, specifically in
   regard to the Open Shortest First (OSPF) protocol.  There are two
   general sections in this document, the first discusses advantages and
   limitations of specific OSPF convergence tests, and the second
   discusses more general pitfalls to be considered when routing
   protocol convergence is tested.

1.  Introduction

   There is a growing interest in testing single router control plane
   convergence for routing protocols, and many people are looking at
   testing methodologies that can provide information on how long it
   takes for a network to converge after various network events occur.
   It is important to consider the framework within which any given
   convergence test is executed when one attempts to apply the results
   of the testing, since the framework can have a major impact on the
   results.  For instance, determining when a network is converged, what
   parts of the router's operation are considered within the testing,
   and other such things will have a major impact on the apparent
   performance that routing protocols provide.

RFC 4063          Considerations in OSPF Benchmarking         April 2005


   This document describes in detail various benefits and pitfalls of
   tests described in [BENCHMARK].  It also explains how such
   measurements can be useful for providers and the research community.

   NOTE: In this document, the word "convergence" refers to single
   router control plane convergence [TERM].
