MPLS故障恢复中的丢包与失序研究

Research on Packet Loss and Disorder of MPLS-based Recovery

该文分析了MPLS网络中的Makam和Haskin两种故障恢复机制,Makam机制会造成的数据包的丢失,Haskin可以避免这个问题,但会导致数据包失序的问题,该文提出了在Haskin的基础上使用缓冲区来避免数据包的失序,并给出了缓冲区大小的估计式,以及估计式中相关参数的近似计算方法。

This paper concern about packet loss and disorder of two MPLS-based recovery mechanism which are Makam and askin, Makam cause packet loss ,and Haskin solve this problem ,but it cause disorder .This paper use buffer in Haskin mechanism to avoid packet disorder, it present the formula of the size of buffer and the methods to calculate the parameters.
