  6. Although the congestion control research of host - ends has made great strides, the current queue management mechanism in router is not able to provide end - to - end congestion control mechanism to sustain the above environment, namely, the unfairness of assigned bandwidth or drop - rate for different types of flows and the synchronization of all tcp flows in network. so it is necessary to improve the classical queue management mecnanism such as drop _ tail and red in order to boost the qos ( quality of service ). this article analyzes the main traits of host - ends congestion control and all kinds of fashionable queue management machanism, which include queue mechanism with absolute priority, weighted fair queue mechanism and class - based queue mechanism

    本文分析了主機端的擁塞控制機制和網路中路由器的現有各種隊列管理機制：絕對優先級隊列機制、加權公平隊列（ weightedfairqueue ） [ 1 ]機制、基於類的隊列（ class - basedqueue ） [ 2 ]機制以及red （ randomearlydetection ） [ 3 ]機制的主要特點，並重點針對ietf （ internetengineeringtaskforce ）推薦的把red演算法與明確的擁塞通告ecn （ explicitcongestionnotification ） [ 4 ]結合的方法進行了分析，發現隨著internet流量的日益遞增， red機制的依賴平均隊列長度來管理擁塞控制的演算法並不能有效地阻止包丟失：與drop - tail相比， red確實消除了對陣發流量（ tcp ）的偏見，但是增加了平滑流量（ udp ）的丟包概率。
