Abstract

This document describes the terms to be used in a methodology that determines the IP packet forwarding performance of IP routers as a function of the forwarding information base installed within a router. The forwarding performance of an IP router may be dependent upon or may be linked to the composition and size of the forwarding information base installed within a router. This memo provides information for the Internet community.

1. Introduction

This document defines terms that are to be used in a methodology that determines the IP packet forwarding performance of IP routers as a function of the forwarding information base installed within the router.

The objective of this methodology is to evaluate the performance levels of IP routers...
