摘要 解决了实现逻辑节点迁移的两个主要问题。首先是逻辑节点的状态迁移;其次是,迁移过程中被迁移的逻辑节点与系统其余部分通信链路的保留以及逻辑节点的并发迁移处理。为了有效地进行负载均衡,迁移行为对系统产生的影响应减至最小。文章实现的迁移机制只用到较少的系统拓扑知识,而且只有迁移逻辑节点本身在移动时被要求停止计算。此算法同样适用于其它的分布式计算。 This paper solves two main problems in implementing migration of logical node. The first is how to capture states of the migrated logical node; the second is how to maintain the communication links between the migrated logical nodes and other parts of the system during migration and how to handle the concurrent migration. To allow efficient load balancing, migration should have the minimal effect on the system. The implemented mechanism uses minimal knowledge of the system topology and requires only the migrated logical node to stop computing while in transit, which makes this algorithm applicable to other distributed computations.
