泛在末梢环境下,当各移动终端为用户提供业务时,终端的移动性或电量有限性会导致业务路径发生故障.为了快速高效地为用户恢复业务,提高业务传输的可靠性,提出了动态业务恢复机制,可灵活地维护在业务传输路径上的数据,在数据传输失败时,上游恢复点为下游恢复点直接恢复数据.仿真实验结果证明,该机制能够有效降低业务请求失败率,缩短执行时间.
In the ubiquitous peripheral environment, when mobile terminals provide services to users, terminal mobility or power limitation will lead to the failure of the service path.In order to restore services to users quickly and efficiently and improve the reliability of service transmission, a dynamic The service recovery mechanism can flexibly maintain the data on the service transmission path, and when the data transmission fails, the upstream recovery point directly restores the data to the downstream recovery point.The simulation results show that the mechanism can effectively reduce the failure rate of service requests and shorten the execution time.
