随着云计算的发展，越来越多的公司开始部署自己的数据中心，虚拟化技术在数据中心中得到了广泛的应用，而虚拟交换机作为虚拟化中的一项重要技术，对数据中心中虚拟机间通信的性能起着重要作用。近些年以Open vSwitch为代表的一些软件实现的虚拟交换机逐渐发展了起来，Open vSwitch部署在系统内核的hypervisor层，与系统内核协同完成数据包交换功能，但是这种纯软件实现的交换机存在一些缺点，主要体现在运行期间占用过多的系统资源，影响了虚拟机的性能，另外由于受系统资源限制，导致数据包的处理效率比较低。本文提出了一种用NetFPGA硬件方式实现Open vSwitch核心态的方案，并实现了硬件中的功能模块的源码，即使用硬件处理的方式数据包处理的功能，这样既减少了处理数据包时的系统资源的消耗，同时也提高了数据包的处理速度,最后搭建环境对该硬件实现方案的功能做了简单的测试。

With the development of cloud computing, as a key technology of datacenter, virtualization is becoming more and more important. In order to solve the problem of communication between the virtual machines, the virtual switch technology has been rapid development. The most famous virtual switch is Open vSwitch which is a software switch, it works in Linux kernel, to finish the switch of packets between different virtual machines. however, it consume a lot of system resources, in addition, due to resource constraints, the packet processing efficiendy of Open vSwitch is low. In this paper, we give a proposal that use NetFPGA to realize the function of packets process, Using the hardware like NetFPGA can be more efficient to process data packets than software, simultaneously, the NetFPGA takes up less system resources. At last, we built a test environment to test the hardware proposal.
