| 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. |
