| 摘 要： | 近年来，UDP等非响应流抢占TCP等响应流的现象越来越严重。提出全局主动带宽调整算法（GABA），通过网络中核心路由器与边缘路由器之间的协作，在核心路由器获取非响应流的信息，在边缘路由器阻止非响应流的大量进入。通过NS2仿真表明，GABA可以有效提高网络利用率和带宽分配的公平性。 |
| 关 键 词： | 响应流 非响应流 全局主动带宽调整 核心路由器 边缘路由器 |

| Abstract: | In recent years, there has been a more and more serious phenomenon that the unresponsive flows such as UDP have occupied the bandwidth of responsive flows such as TCP. An algorithm called GABA (Global Active Bandwidth Adjustment) algorithm was proposed with the cooperation of edge routers and core routers. Core router got the information of unresponsive flows and edge router blocked invalid unresponsive flows. The NS2 experiment proves that GABA can improve the network utilization and the bandwidth fairness. |
| Keywords: | responsive flow unresponsive flow Global Active Bandwidth Adjustment (GABA) core router edge router |
