【摘要】 本文提出了新的衡量网络带宽分配算法的公平性和效率的定义。基于这个定义对不同的网络带宽公平性分配算法之间的公平性和效率进行了比较。带宽分配问题可以看作是求解一个最大化效用函数的问题,给出了一个新的效用函数,对它在具体网络中的分配和其他公平性分配算法进行比较,建立了它们之间的一种对应关系。更多还原

【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.更多还原
