摘　　要：光突发交换网络是近年来新兴的结合光电路交换与光分组交换优点的新型光网络。为更好管理及维护光突发交换网络,设计光突发交换网络差别数据检测系统。系统中边缘节点模块获取光突发交换网络中的光网络数据后,通过光交叉连接设备将数据传输给检测模块,检测模块中的各探测模块检测到光网络数据后,通过差别数据识别模块发送至告警过滤模块,通过告警过滤模块过滤误告警数据后,将有效光网络数据发送至差别数据显示模块。差别数据识别模块依据差别数据检测原理检测光突发交换网络中的差别数据,告警过滤模块采用不同告警下差别数据检测方法,实现不同告警情况的差别数据的有效检测。通过仿真实验表明,该检测系统可准确检测光突发交换网络中差别数据,准确率高达99. 5%,且抗噪性能佳。Optical burst switching network is a new type of optical network combining the advantages of optical circuit switching and optical packet switching.In order to better manage and maintain the optical burst exchange network,a differential data detection system for optical burst exchange network is designed.After the edge node module in the system obtains the optical network data in the optical burst exchange network,the data is transmitted to the detection module through optical cross connection device.Through the differential data recognition module,the optical data detected by each detection modules is sent to alert filtering module,and the effective optical network data is sent to the differential data display module after alert filtering.The differential data recognition module detects the difference data in the optical burst exchange network based on the principle of differential data detection,and the alert filtering module adopts the different data detection method under different warnings to achieve effective detection of different data in different alert situations.The simulation results show that the detection system can accurately detect the difference data in the optical burst exchange network with an accuracy rate of 99.5%and has good anti-noise performance.
