摘要
基于物理光纤技术的全光网络在波长变换和管理中,当遇到网络产生未知波长的情况时,会引起故障告警的泛滥。考虑到全光网络透明性和高速率的特点,为了不丢失非故障源的信息,采用一种分布式的故障信息管理的方式,寻找故障源的恢复算法,能很好地解决告警泛滥的问题。该算法通过使用时间差的方法对故障源头的情况进行分析。通过进行计算机仿真,结果表明,该分布式算法能使全光网络中故障恢复问题变得简单和高效。
In response to a series of difficulties in the transfer of wavelength transformation as well as management based on the all-optical networks in static physical fiber technology and unknown wavelengths, the overflow of failure warning will be produced. Considering the characteristics of all-optical networks and that the packet of the non-failure-headstream cannot be lost, this paper presents a new and strategic distributed algorithm for failure recovery and also analyses the situation of network＇s recovery in such arithmetical application. The results of simulation indicated that the algorithm proposed could solve the problem well and make the work of failure recovery simple and efficient.
