一种光突发交换网络的故障监测与定位机制

提出了一种用于光突发交换（OBS）网络的故障监测机制。针对传统光网络监测方法在OBS网络环境下必然产生过多误告警的缺陷，充分利用突发控制分组（BHD）所包含的数据信道信息，控制监测点的告警允许时闸，使故障监测点为故障定位模块提供更为可靠的告警信息，从而达到快速故障检测和故障定位的目的。仿真和分析表明，该机制能有效减少误告警数目，而几乎不产生漏告警，特别是在需要的故障检测时间越短时，过滤掉的误告警数目越多。

A Fault Detection and Location Mechanism for Optical Burst Switching Networks

A new fault monitoring mechanism for optical burst switching(OBS) networks is propoed pertinent to that a lot of false alarms will be generated in OBS circumstance if traditional optical network monitoring method is only used.Using data channel information contained in the burst header packet of OBS,the mechanism can control the alarm-permitting time and discard the redundant alarming information.So it can provide reliable alarming information for fault location module,and effectively decrease the number of false alarms while there is almost no missing alarm.Simulation results validate that the shorter time the fault detection needs,the more false alarms are filtered.
