Abstract

Abstract: In order to improve the unfairness of each flow’s bandwidth allocation in the Internet，a NFTFP algorithm is proposed to punish non-friendly TCP flows based on buffer management.The algorithm will record the bandwidth of each connection in the buffer，discriminate and punish non-friendly TCP flows，then enhance the fairness to occupy the bandwidth for different flows.In the coexistence environment between the normal TCP flows and non-friendly TCP flows，the simulations validate that NFTFP can raise the punishment strength to non-friendly TCP flows，obtain better fairness than RED，as well as keep high link utilization.

摘要： 为了改善Internet中各流量带宽分配的不公平性，提出一种适于缓存管理的非TCP友好流的惩罚算法（NFTFP算法）。通过在缓冲区记录每个连接所占用的带宽，对于非TCP友好流量进行识别和惩罚，从而提高不同数据流享用带宽的公平性。仿真实验表明在标准TCP流量和非TCP友好流共存的环境下，NFTFP算法能提高对非TCP友好流的惩罚力度，在保持较高的链路利用率的同时，获得比RED算法更好的公平性。
