基于OPNET的以太网性能仿真研究

Research of Simulation for Ethernet Based on OPNET

以太网应用越来越普遍,而实时性是影响以太网应用的重要指标。本文利用OPNET软件建立了办公室内的小型局域网,对它的以太网时延进行仿真,然后仿真加入视频业务后的以太网时延。研究结果表明,标准以太网的带宽不足以满足视频业务,需要拓展带宽。

Ethernet is more and more widely used nowadays and the real-time performance is the most important factor for the application of the Ethernet.Based on the software OPNET,a small office local area network is built and the Ethernet delay is simulated by inserting the video service.The result indicates that it is necessary to expand the bandwidth because the bandwidth of standard Ethernet is not big enough to meet the needs of video service.
