MPLS故障恢复中报文丢失及失序问题研究

Study on message drop and disorder in MPLS fault restoration

介绍了几种主要的MPLS故障恢复模型,分析了各种模型使用过程中产生的报文丢失及失序问题。提出了一种基于Haskin故障恢复方法的故障恢复模型,并对该模型中流量重定向、流量切换以及流量汇聚的方法进行详细阐述。该模型能较好的解决由于流量切换而引起的报文丢失及失序问题。最后结论中指出了模型的不足,并提出了以后的研究方向。

Several kind of MPLS fault restoration model is introduced, the message drop and disorder problem, which produced in use of these models are analyzed, a fault restoration model based on Haskin restoration mechanism is proposed, and the method of flow rerouting, flow switching and flow merging which used in the model are expatiated. This model is a better solution to message dropping and disordering due to flow switching. Finally the limitation of this model and the later research direction are proposed.
