基于OPNET的网络压力仿真

针对网络规划和优化过程中压力测试工具使用的不足，提出基于OPNET的网络压力仿真方法，建立包含不同网络负载的多个仿真场景，以对FFP服务的压力仿真为例，收集并对比这些场景中服务器和网络的吞吐量、时延及丢包率，分析各种网络运行数据，得出网络负载情况。结果表明，利用OPNET软件可以有效地进行网络压力仿真。

Simulation of Network Pressure Based on OPNET

Aiming at the deficiency of pressure testing tool in the process of network planning and optimization, a network pressure simulation method based on OPNET is proposed. Through the establishment of several network simulation scenarios with different load in OPNET, taking the network pressure simulation on FTP service for an instance, several simulation statistics such as CPU utilization, throughput, delay and packet loss rate can be collected and compared, and all the network running data can be analyzed. The network load can be shown. Results show that the network pressure can be simulated efficiently based on OPNET software.
