Abstract: The network redirection model is proposed and cross-domain migration of Virtual Machine(VM) is achieved Local Area Network (LAN) or in Wide Area Network(WAN). With Address Resolution Protocol(ARP) synchronization, the unidirectional IP tunnel is quickly established between the source node and the migrated VM. The data is redirected to the VM. With dual IP stacks, all new requests are responded by the new IP and old sessions are maintained. Experimental results show that the model can effectively reduce the deployment time, optimize forwarding path, lower latency, achieve transparent cross-domain migration.

摘要： 提出一个网络重定向模型，实现局域网或广域网环境下的虚拟机跨域迁移。利用地址解析协议同步策略，在源节点和迁移后的虚拟机之间快速建立单向IP隧道，将数据重定向至虚拟机。采用IP双栈方式，使虚拟机在保持原有会话的同时，通过新增IP响应所有新的连接请求。实验结果表明，该模型能减少部署时间，优化数据转发路径，降低响应延迟，实现跨域迁移。
