Correct router interface modeling

Abstract

The aim of this paper is to determine how to model router interface in order to accurately predict packet drops. There is an enormous amount of research on traffic models reported, however, a model of router interface has not gained proper consideration yet.Our experiments reveal that an incorrect model of the router interface can result in a significant disparity between drop probabilities measured on a physical interface and derived from a trace-driven simulation study. In this paper an accurate model of the router interface (Cisco IOS-based routers with a non-distributed architecture) was presented.
