Abstract: By connecting multiple virtual machines in different hosts in different networks, the virtual network is set up. The relevant management scheme is proposed. P2P communication mode is used between one-to-one nodes, while multicast communication mode is used among ont-to-many nodes, which need not other node to transmit the communication, and promote the efficiency of data transmission in virtual network. This scheme is tested and analyzed, and the results show its feasibility.

Key words: virtual machine network, P2P mode, transmission efficiency

摘要： 通过连接分布在不同网络中不同宿主机上的多个虚拟机构建虚拟网络，并提出相应的管理方案。对于一对一节点间的通信采用P2P模式，而一对多节点间的通信采用组播模式，使节点间的通信无需其他节点转发，从而提高虚拟网络中数据的传输效率。对该方案进行实验分析，结果验证了其可行性。
