Analysis of an Equal-Cost Multi-Path Algorithm
RFC 2992, “Analysis of an Equal-Cost Multi-Path Algorithm”, is an Informational document published in November 2000 by C. Hopps. The canonical text is published by the RFC Editor.
Abstract
Equal-cost multi-path (ECMP) is a routing technique for routing packets along multiple paths of equal cost. The forwarding engine identifies paths by next-hop. When forwarding a packet the router must decide which next-hop (path) to use. This document gives an analysis of one method for making that decision. The analysis includes the performance of the algorithm and the disruption caused by changes to the set of next-hops. This memo provides information for the Internet community.
