网络性能的分析、评价模型及其软件实现

通过网络参数设置、建立性能分析模型、采用新网络测试技术和使用开源网络测试软件Cacti进行具体网络测试与分析。搭建一个小型的骨干网络来模拟运营商的IP承载网,在IP网络的核心,以具体的网络故障排除作为分析实例,使用Cacti对网络流量进行监控和对流量图进行分析,以及性能测试与网络性能瓶颈分析,最后提出相关优化解决方案。

Network performance analysis,evaluation model and software implementation

Specific network was tested and researched in this paper through setting the network parameters,establishing performance analysis model,adopting new testing techniques and using open source network testing software Cacti.An experimental platform based on a small backbone network was used to simulate the operator’s IP bearer network,and a specific network failure analysis was taken as an example for validating the method.In the analyses,Cacti was used to monitor the network traffic,analyze the flow diagram,test the performance and analyze the network performance bottleneck orderly to make optimization solutions for the core of the IP network.
