由于传统网络性能评测[1]存在不足,网络研究者更倾向使用仿真器构建网络测试床进行协议评测。计算机网络逐渐趋向于核心高速化和边缘无线化[2],网络协议必须随之改变,尤其是高速数据传输协议[3]。目前网络实验床构建方式较单一,链路速率低且端主机平台限制为Linux系统,难以实现精准网络流量控制,不利于协议的评测。本文提出了兼容多系统网络实验床的构建方法,并提供多种检测手段验证实验床的流控配置。实验表明方案可行,且能够实现高速网络的流量控制。
Due to the shortcomings of the traditional network performance evaluation [1], network researchers are more inclined to use the simulator to build network test bed for protocol evaluation. Computer networks gradually tend to be core high-speed and edge wireless [2]. The network protocols must be changed, especially the high-speed data transfer protocol [3]. At present, the construction of network experimental bed is relatively simple, the link speed is low, and the end host platform is limited to a Linux system, so that precise network traffic control is difficult to achieve, which is not conducive to protocol evaluation. In this paper, a method of constructing a multi-system network experiment bed is proposed, and a variety of testing methods are provided to verify the flow control configuration of the experiment bed. Experiments show that the scheme is feasible and can realize the flow control of high-speed network.
