Abstract:

This paper presents new definitions to evaluate fairness and efficiency in bandwidth allocation. Based on these definitions, we compare the fairness and efficiency among different bandwidth allocation algorithms. The bandwidth allocation problem can be treated as solving a utility maximization problem. We propose a new utility function and compare the bandwidth allocation algorithm using this function with other fairness algorithms,and establish the relationship between them.
