摘要:

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.

关键词: 泛在末梢环境, 恢复, 传输, 分组

Abstract:

When the mobile devices provide services for a user in ubiquitous stub environment, some service transmission paths will be out of work because of device movement or limited power. The main purpose of the article is to seek a way for quick service recovery and reliable service transmission. This author put forward a dynamic service recovery mechanism which can maintain the data in the service transmission path flexibly. When the service transmission fails, the upstream recovery point directly resends the service data to its downstream recovery point. Simulations show that this mechanism can effectively reduce the request failure probability and the execution time.

Key words: ubiquitous stub environment, recovery, transmission, group
