摘　　要：为解决数据中心多网络设备、多网络端口的问题,采用IRF将多台网络设备进行连接,"横向整合"起来组成一个"联合设备",实现跨设备链路聚合,增加带宽并提高链路可靠性。为解决数据中心各个虚拟机的安全性问题,在虚拟机网络内部采用PVLAN技术隔离各个虚拟机,提高网络的安全性。将两种方案应用于实际的校园数据中心网络建设中。测试结果表明,该方案能扩展网络端口数量和交换能力、增强网络的可靠性和提高网络的安全性。In order to solve the problem that too many of network equipments and network ports con- centrate in data center, one horizontally integration scheme is used to connect multiple network e- quipments with IRF, which is able to realize cross-device link aggregation and increase the band- width and reliability. In order to solve the security problem of each virtual machine in data center, PVLAN is used to separate virtual machine inside the network of virtual machines to enhance the se- curity of the network. After applying these two schemes to the actual campus network construction, the experimental results show that the proposed schemes are able to extend the amount of network ports and switching capabilities, also can enhance the network reliability and improve the network security.
