提高传输以太网汇聚业务安全系数探讨

在日常维护过程中,唐包线红外线、牵引、电力等传输以太网汇聚业务主用或备用通道出现过几次全部中断的故障,用户侧没有相应的排查、定位及恢复手段,需通过传输网和数据网定位故障点,对维护人员业务水平要求高,网管操作复杂,排查时间长,影响范围大,危及铁路行车业务正常应用,存在较大安全隐患.通过优化传输以太网汇聚业务组网结构,可防...

Discussion on Improving Security Factor of Transmitting Ethernet Aggregation Service

During daily maintenance,the main and standby channels of transmitting Ethernet aggregation services such as infrared ray,traction and electric power on Tang-Bao line have been completely interrupted for several times,and there is no troubleshooting,locating and recovery method available on the user side.It requires to locate the fault point by transmission network and data network,which has high professional requirements for maintenance personnel,complicated operation of network administrator,long troubleshooting time and wide impact range,and endangers the normal application of railway train operation and exists great hidden safety risks.This paper discusses that by optimizing the networking structure of the transmitting Ethernet aggregation service,the main and standby channels of the transmitting Ethernet aggregation service can be prevented from totally interrupted,the number of faults and the impact range can be reduced,the fault location can be quickly located in the event of a fault and the network administrator can easy to operate.Thus,the security and reliability of the railway transmitting Ethernet aggregation service can be effectively improved.
