Abstract

The migration of virtual router has attracted a lot of attention from researchers in the new network architecture field, due to the potential to cope with emerging challenges, such as energy consumption and resource fragmentation problem. In this paper, we focus on general virtual router architecture VRSM (Virtual Router Supporting Migration), composed by a cluster of servers. Compared with other architectures, VRSM introduces intelligently interface plane, management switch and data switch. The interface plane is used to switch data traffic to new forward instances and other two switches can guarantee bandwidth separation between migration traffic and data traffic in migration process. Based on VRSM architecture, we put forward a migration strategy DMVR (Dynamic Migration of Virtual Router), which can dynamically migrate a virtual router instance from one physical server to another without disrupting the network topology. Our experiment shows that DMVR strategy results in minimal impact in the data plane and brief downtime in the control plane.

虚拟路由器的动态迁移

虚拟路由器的迁移由于具有应对能源消耗和资源碎片化等新挑战的潜力，引起了新网络架构领域研究者的广泛关注。本文主要研究由服务器集群组成的通用虚拟路由器体系结构VRSM (virtual router support Migration)。与其他架构相比，VRSM引入了智能接口平面、管理交换机和数据交换机。接口平面用于将数据流量切换到新的转发实例，另外两个交换机可以保证迁移过程中迁移流量和数据流量的带宽隔离。基于VRSM架构，提出了虚拟路由器动态迁移策略DMVR (Dynamic migration of Virtual Router)，该策略可以在不破坏网络拓扑结构的情况下，将虚拟路由器实例从一台物理服务器动态迁移到另一台物理服务器。我们的实验表明，DMVR策略在数据平面上的影响最小，在控制平面上的停机时间很短。
