摘要
SDN的出现开展了计算机虚拟网络模式新的转变,实现了将控制层面与数据转发分离的功能。利用OpenFlow协议对控制器与交换机进行交流。针对网络传输的能耗问题,提出虚拟网络动态切换技术,在该系统中虚拟机之间通信有两条路径可供选择,即光交换机和电交换机。通过对交换机的切换,实现虚拟网络流量的整合,减少物理网络资源的冗余浪费,从而达到优化数据网络能耗的目的。通过Ping与Netperf这两个测试工具测出丢包率、延迟及流量值,这些数值的变化证明了所提系统可正常运行。
The emergence of SDN has carried out a new transformation of computer virtual network mode and realized the function of separating control level from data forwarding.The OpenFlow protocol supports the communication of the controller and the switch.In allusion to the energy consumption of network transmission,a virtual network dynamic switching technology is proposed.In this system,there are two paths for communication between virtual machines,namely optical switch and electrical switch.By switching the switch,the integration of virtual network traffic is realized,and the redundancy and waste of physical network resources are reduced,so as to optimize the energy consumption of data network.Ping and Netperf are the system’s test tools,by which the packet loss rates,latency,and traffic value are measured.It proves that the proposed system can run normally.
