摘　　要：根据MPLS故障恢复机制的原理,采用功能强大的网络仿真软件NS-2作为工具,讨论了近年来网络研究的必然趋势——利用容错技术构造高可靠网络系统。通过原理模拟出一种MPLS网络的Global恢复模型,结合平均无故障时间和恢复时间等来验证该模型在网络发生故障时,依旧能保证系统的可靠性和可用性。通过延迟、吞吐量等仿真数据得出,采用适当的压缩算法能够加速数据在网络上的传送。在保证网络传输的稳定性和可靠性的同时,可供其它同类网络故障恢复仿真参考,也可以直接应用到实际网络中。Based on the theory of MPLS fault recovery mechanism, and the network simulation software NS-2 is adopted as a tool to discuss the recent trend ofnetwork research-the use of fault-tolerant technology that is highly reliable network structure. A MPLS global recovery model is simulated via theory, combined with MTBF and resume time to validate the system＇ s reliability and availability when the network goes wrong. Besides, according to the data of delay and throughput, adopting appropriate compression algorithm also can speed up data transmission on the network. This is done as an example for analogous kinds of network fault recovery simulation, applied directly in real network at the same time with the pledge of transmission reliable and available.
