基于网络功能虚拟化的网络试验平台的设计与实现

Design and Implementation of Network Test Platform Based on Network Function Virtualization

21世纪已进入了信息时代,网络平台的使用越来越广泛,新型的网络设备在投入使用之前要经过严格的测试把关,但是这种测试在越真实的网络环境下进行效果才会越明显,所以要通过购置大量的网络设备来搭建虚拟的网络环境,越接近真实的网络环境会越成功。然而,对于很多较为复杂的网络系统来说,这样做会面临很多现实问题,比如,成本巨大、技术要求过高、耗时过长等。虚拟化技术是将现实的资源转化成虚拟的资源,并且使其更为抽象,使用虚拟技术,用软件来实现网络的功能,以此来代替传统的硬件加软件方式实现各种网络功能。可以通过网络试验平台来实现对资源的管理以及远程访问,同时还能描述服务器端性能监控以及绘制和存储网络拓扑等,基本上可以满足网络试验的常规要求。

In the 21st century,the information age has entered into force.The use of network platforms is becoming more and more widespread.New types of network equipment undergo rigorous tests before they are put into use.However,this test is more effective in a real network environment will be more obvious,so through the purchase of a large number of network devices to build a virtual network environment,the closer the real network environment,the more successful.However,for many more complex network systems,this will face many practical problems,such as the cost is huge,the technical requirements are too high,take too long and so on.Virtualization technology is the real resource into virtual resources,and let it appear more abstract,the use of virtual technology,software to achieve the function of the network,as a way to replace the traditional hardware and software to achieve a variety of network functions.We can manage the resources and remote access through the network test platform,meanwhile we can describe the performance monitoring of the server and the drawing and storage of the network topology,which basically meet the general requirements of the network test.
