网络通信控制实验平台的设计与实现

Design and realization of network communication control test platform

为了实现从网络通信控制算法的研究到应用转化,设计和构建了网络通信控制实验平台。根据通信控制实验对平台的要求,给出了平台的设计方案和思想,详细阐述了平台的构建过程。该实验平台可以通过网卡、路由器、源端数据发送量等设置,模拟实际通信网的不同拥塞程度、丢包率、延时等状况,并能在网络中的各个节点纪录包的通过和丢弃时间,最终得到吞吐量、延时、延时抖动、丢包率等实验数据。平台实际测试表明,构建的实验平台达到了预期的设计目标。

In order to implement the transformation from network communication control algorithm to application, a network communication control test platform is designed and constructed. According to the request of communication control test platform, the design proposal is given and the process of platform construction is discussed in detail. By setting the net cards, routers, and data which are sent by sources in the test platform, simulate the different situations of congestion, drops, delay and so on in practical network. The time of every packet which passes or drops at any node is recorded; so that throughput, delay time, jitter is calculated. The tests on the platform show that the test platform constructed has achieved the desired design destination.
