一种区分服务网络边缘路由器动态阈值的公平性标记算法
Fairness marker algorithm based on dynamic thresholds for edge routers in DiffServ networks
摘要
Abstract
DiffServ packet marking algorithms have not considered traffic features. This result in that fairness is present in the bandwidth competition between different flows. In order to solve the fairness problems, this paper presented dynamic threshold three color marking(DTTCM) algorithm appling in network edge routers. It marked packets according to certain strategy by changing threshold of flow speed minth and maxth. This ensured that flows enjoy network resources fairly when bandwidth was insufficient. The simulation indicates that DTTCM has better performance in the assignment of bandwidth among UDP and TCP, as well as the assignment of excess bandwidths among the aggregates.关键词
