摘　　要：针对源抑制机制在内网流量控制中存在的带宽利用率不高的问题,提出一种基于源抑制的内网流量自适应控制算法。该算法在网关上监视网络流量,当总流量小于阈值时,不执行流量控制;当总流量超过阈值时,开始统计每个用户的流量,找出流量较大的用户,对于下载流量直接在网关上限速,对于上传流量通知接入交换机控制用户流量。在Linux中实现基于源抑制的内网流量自适应控制算法,并对其进行测试,结果表明该算法能够有效控制内网流量,实现带宽公平和高效利用。Aiming at the problem that bandwidth utilization is not high in source quench based LAN traffic control, a source quench based LAN traffic adaptive control algorithm is proposed. The algorithm monitors LAN traffic in gateway, when total flow rate is smaller than threshold, it does not perform traffic control; when total flow exceeds threshold, it begins to compute each user＇ s traffic, then finds out larger users, for download traffic it directly limits traffic in the gateway, and for upload traffic it notifies access switch to control user traffic. The source quench based LAN traffic adaptive control algorithm is implemented and tested in Linux. The test results show that the algorithm can effectively control network traffic to achieve fair and efficient use of bandwidth.
