| 摘 要： | 不同应用对生存性的要求不同，为此，提出了一种基于MPLS的多优先级综合控制故障恢复机制．该机制将路由机制与网管系统相配合，区分不同应用的优先级和生存性要求，快速恢复受影响的高级别流量。同时叉充分考虑资源的利用效率．仿真结果表明，该机制能够100％地恢复受影响的所有流量，与扩散法相比，其恢复速度平均提高了52％。

| Abstract: | Based on multi-protocol label switching (MPLS) , a general multi-priority restoration mechanism is proposed considering survivability requirements of different kinds of application. It integrates the current routing mechanism and network management system,and can protect the higher priority traffic and achieve efficient resource utility at the same time. The simulation results indicate that the restoration ratio reaches 100% and the restoration speed increases 52% in comparison with that of the full-provision mechanism. |
