在一个分布式设备中,为了检测网络业务的通断情况,需要应用到大规格的OAM(Operation Administration and Maintenance,操作维护管理)资源。传统的实现方法是在每块线卡上设置OAM芯片来进行OAM的检测,但由于每块线卡对资源总规格有限制,往往分配给OAM芯片的资源规格较少,难以实现OAM大规格的应用。而且每块线卡都具有OAM芯片,但业务会分到某块线卡上,由于每块线卡的OAM处理能力有限,很难实现多块线卡上的业务的处理均衡,产生分到办卡上的业务不能完全进行OAM处理,而其他线卡OAM芯片闲置的现象,造成业务不能与OAM处理匹配,整体处理能力不高。另外,当业务所在线卡出现切换时,对业务的处理也会切换到新线卡的OAM芯片上,进而造成OAM出现不稳态的现象。In a distributed device, in order to detect the on/off of network services, it is required to apply to large-scale OAM (Operation Administration and Maintenance) resources. The traditional implementation method is to set up an OAM chip on each line card to perform OAM detection. However, since each line card has a limitation on the total resource specifications, the resource specifications allocated to the OAM chip are often small, and it is difficult to implement OAM large specifications. application. Moreover, each line card has an OAM chip, but the service is divided into a certain line card. Since the OAM processing capability of each line card is limited, it is difficult to achieve processing balance on the service of multiple line cards, and the branch office is generated. The service on the card cannot be completely processed by the OAM, and the other line card OAM chip is idle. The service cannot be matched with the OAM processing, and the overall processing capability is not high. In addition, when the online card of the service is switched, the processing of the service is also switched to the OAM chip of the new line card, thereby causing the OAM to be unstable.

Specifically, in the downlink direction, the primary OAM card and the standby OAM card add a packet header that encapsulates the next hop information to the front end of the OAM packet, and then sends the packet header to the switch board. The switch board receives only OAM. The OAM packet sent by the card is sent to the corresponding service line card (that is, the service line card corresponding to the next hop information). The service line card encapsulates the packet header and sends it to the corresponding line. In the uplink direction, the service board receives the packet from the line, and the identified OAM packet is sent to the active OAM board and the standby OAM board through the switch board. The OAM board and the standby OAM board are used internally. The received OAM file is processed the same.
本发明的OAM板卡可以为多个,并且可以根据不同的实际使用情况来进行配置。当有多个OAM板卡时,可以都是主用OAM板卡;也可以设置一个备用OAM板卡,其余的都是主用OAM板卡;或者配置部分主用OAM板卡和部分备用OAM板卡;但是无论是如何配置,主用OAM板卡和备用OAM板卡的内部结构和作用均与上述实施例中相同,此处不再赘述。The OAM board of the present invention can be multiple and can be configured according to different actual use situations. When there are multiple OAM boards, they can all be used as the main OAM board. You can also set up a spare OAM board. The rest are the main OAM boards. Or configure some main OAM boards and some spare OAM boards. The internal structure and function of the primary OAM card and the standby OAM card are the same as those in the foregoing embodiment, and are not described here.
