摘要： 在分析了现有迁移机制的基础上,提出了一种基于迁移计划图的结构化迁移机制。迁移计划图能有效地描述Agent的迁移语义;载有迁移计划图的Agent能根据迁移计划图和当前网络的软硬件环境及其它负载信息,动态地规划出最佳迁移路径,充分体现了Agent迁移的自主性和反应性。该机制还可避免网络断连、主机故障及服务失效引起的迁移失败。给出了该机制的实现。

Abstract: After analyzing some representative migration mechanism, the paper presents a new structured migration mechanism of mobile agentbased on itinerary graph. Itinerary graph can effectively describe the migration semantics; mobile agent with itinerary graph can perceive the changesof network environment and dynamically choose the best migration path based on these changes, which embodies fully the reactivity and autonomyof agent. The mechanism also avoids migration failure caused by network disconnection and compute node crashing and service invalidation. Thepaper gives the mechanism implementation.
