Description
一种监测芯片损坏告警的方法 Method for monitoring chip damage alarm
技术领域 Technical field
本发明涉及数字通信领域中监测芯片损坏告警方法， 具体地说， 是涉及 光传输领域中一种监测芯片损坏告警方法。 背景技术 The invention relates to a method for monitoring chip damage alarm in the field of digital communication, and in particular to a method for monitoring chip damage alarm in the field of optical transmission. Background technique
目前， 在光传输设备中， 很多设备提供了一些单板备份保护的措施用以 弥补采用的传输保护协议对业务保护的不完善。但目前提供的很多单板保护 所实现的功能十分有限， 除了少数的可以检测到的几种电源告警或 CPU相关 芯片告警， 会在出现告警时触发单板在几十毫秒之内发生自动倒换使业务快 速恢复外， 单板上大部分业务流芯片如果出现损坏是不能触发单板的自动倒 换的。 一般情况下， 当发现有可能的告警后， 只能通过维护人员在网管上下 发相应的倒换命令去实现业务从损坏单板向正常单板的切换。从出现告警到 人工切换单板、 告警消失这一过程一般时间都会很长， 会造成几分钟甚至几 个小时的业务中断， 使用户蒙受损失。 At present, in the optical transmission equipment, many devices provide some single-board backup protection measures to compensate for the imperfection of the service protection of the adopted transmission protection protocol. However, the functions of the board protection provided by the board are very limited. In addition to a few types of power alarms or CPU-related chip alarms that can be detected, the board automatically triggers automatic switching within tens of milliseconds. If the service is fast, the switch does not trigger the automatic switchover of the board. Generally, after a possible alarm is found, the maintenance personnel can send and receive the corresponding switchover command on the NMS to switch the service from the damaged board to the normal board. From the time the alarm occurs to the manual switch of the board, the alarm disappears. The general time will be long, causing a few minutes or even hours of business interruption, causing users to suffer losses.
造成这种问题的根本原因是目前的设备不具备实时监测业务流芯片是 否损坏的能力。大多数业务流芯片提供的传输协议告警检测只能检测业务流 本身的告警， 而业务流告警的监测范围非常广， 可能跨越多个设备和光纤通 路， 所以检测业务流的告警无法准确的定位到设备中是否有芯片损坏以及芯 片损坏的位置， 所以目前业务流芯片提供的传输协议中定义的告警是不能作 为监测芯片是否损坏的判据的。 发明内容 The root cause of this problem is that current devices do not have the ability to monitor the flow of business flow chips in real time. The traffic protocol alarm detection provided by most service flow chips can only detect the alarms of the service flow itself. The traffic flow alarms have a wide monitoring range and may span multiple devices and fiber channels. Therefore, the alarms for detecting service flows cannot be accurately located. Whether there is chip damage and the location of chip damage in the device, the alarm defined in the transmission protocol provided by the current service flow chip cannot be used as a criterion for monitoring whether the chip is damaged. Summary of the invention

交叉芯片检测帧头处的数据线校验字节是否是与插入的期望值 96相 同。 如果不同， 表示交叉板接收方向有故障。
如果两块交叉板检测到的都是非期望值， 表示为业务板发送测接口 芯片损坏， 如果一块交叉板为期望值， 一块为非期望值， 则表示接收非 期望值的交叉板接收处接口芯片损坏。可以触发将业务倒换至正常单板。 The cross chip detects whether the data line check byte at the frame header is the same as the inserted expected value 96. If it is different, it indicates that the cross board receiving direction is faulty. If the two cross-boards detect an undesired value, it indicates that the service board sends the interface chip to be damaged. If a cross-board is the expected value and one piece is an undesired value, it means that the interface chip at the receiving end of the cross-board receiving the undesired value is damaged. You can trigger the switchover of the service to a normal board.
