互联网的发展需要网络设备具备支持网络虚拟化和可扩展可编程两大特性。基于此出现了许多原型系统，虚拟路由器通过采用虚拟化技术和可扩展路由器软件来满足上述要求。但由于虚拟化本身所带来开销，虚拟路由器的数据包转发性能会受到影响。该文对不同的虚拟技术和可扩展路由软件进行介绍，搭建实验平台，在不同的虚拟环境下测试和评估了其数据包转发性能，并评估了几种常见的虚拟I/O加速技术。

Virtualization and scalability & programmability are two key characteristics to be supported by network devices for the development of Internet. In recent years, researchers have proposed many prototypes based on these two requirements. The virtual router is one representative prototype, which realizes these two requirements by the virtualization technique and scalable routing software. However, due to the overhead of virtualization techniques, the forwarding performance of a virtual router is usually limited. This paper investigates different virtualization techniques and scalable routing software, establishes the test-bed and evaluates the forwarding performance under different virtualization techniques, and conducts the assessment on several typical virtual I/O acceleration techniques.
