摘要 实体迁移技术有利于改善大规模分布式仿真系统的性能,其中迁移期间的时间同步是其关键与难点.基于HLA联邦仿真框架,研究了实体迁移中的时间同步机制;分析了迁移期间邦元的状态变迁情况;给出了旧邦元转发消息以及新邦元接收和处理消息时所需的同步策略;保证了按时戳序处理消息.迁移期间新旧邦元逻辑时间同步,防止了丢失消息或重复处理同一消息等现象,也能撤销消息,以便乐观同步. Migrating entities are beneficial to improve performance of large-scale distributed simulation systems, while time synchronization during migration is the key and difficult issue. The time synchronization mechanism for migrating entities in HLA (high level architecture) federated simulation is studied. Transition of federates' states is analyzed, and synchronization strategies for the old federate to relay messages and for the new federate to receive and process messages are proposed. Under these strategies, messages are processed in time-stamp order, the logical time of both sides is synchronized, and messages are never lost or duplicated. Message retraction is also supported to enable optimistic synchronization.
