Fairness comparison of FAST TCP and TCP vegas

Abstract

In networking, it is often required to quantify by how much one protocol is fairer than another and how certain parameter setting and/or protocol enhancements improve fairness. This paper provides a framework to evaluate the fairness of various protocols in a general telecommunications network. Within this framework, there are two key components: (1) a benchmark and (2) a single dimension metric. We suggest to use the max-min fairness bandwidth allocation as the benchmark and the Euclidean distance between any bandwidth allocation under any protocol and the max-min bandwidth allocation as the metric. Explicitly, we provide a method to compare the fairness of two sets of bandwidth allocation ..
