摘要:
在DiffServ网络中,存在一些对带宽利用的不公平性。为了解决这些不公平性,该文提出了一种基于TSW的标记算法,称之为TCP友好的公平数据包标记算法,它能以一种近似按比例的方式在各个汇聚流之间公平地分配网络中的剩余带宽,同时还能在汇聚流内部对TCP流和UDP流进行公平的带宽分配。通过仿真试验对算法进行了验证,并与其它几种标记算法进行比较,结果证实本算法比其它几种算法具有更好的公平性。
Abstract:
Researchers found unfairness in DifFServ network, to solve this problem, a TSW-based marker is proposed, which is called TCP-friendly Fair Packet Marking algo-rithm(TFPlV[). With this marker, proportional fair sharing of excess bandwidth among ag gregate can be achieved, and so the better fairness between TCP and UDP flows in an aggregate. The validation of this marking algorithm through simulation experimentation is made, and the simulation result is compared with some other marking algorithms, which verifies that the TFPM algorithm has better fairness than other algorithms.
