| 摘 要： | 在基于动态容错代理的Web服务恢复框架中,针对服务失效恢复的替代服务选择问题,提出一种基于多因素运行时评估的服务失效恢复机制,并验证其有效性。该机制综合考虑服务可靠度、性能和网络负载等因素,用一种新的副本选择算法优化服务恢复的效果。该机制能够提高Web服务恢复的可行性和效率,更好地满足用户需求。

| Abstract: | Aiming to the problem of backup selection for web services failover in the service failover framework based on dynamical fault-tolerant proxy,a mechanism of failover based on multi-dimension runtime factors is studied.The kernel backup selection algorithm with the consideration of factors including service reliability,performance and network load is presented.The simulation results show the efficiency of the mechanism. |
