| 摘 要： | 针对单个低速节点的网卡吞吐量无法提供被测链路所需带宽的问题，基于TCP协议，通过多节点并行生成网络流量方式向被测系统输出高带宽负载，从而对被测链路进行带宽测量。实验验证了该并行测量方法的可行性，并通过分析得到TCP协议中影响被测链路带宽的主要因素为TCP窗口大小与缓冲区大小。

| Abstract: | Aiming at the problem that single node network card throughput can not satisfy the bandwidth of the tested link, based on TCP protocol, this paper outputs high bandwidth load for tested system by using multiple nodes to parallel generate network flow, and goes on bandwidth test for link. Experiment validates the feasibility of this parallel measurement method, and gets the main factors which are TCP window size and buffer size in TCP protocol by analyzing. |
