A large-scale oam detection system and method in distributed equipment

Abstract

The present invention relates to the field of distributed devices and provides a large-scale OAM detection system and method in distributed devices. The system comprises an exchange integrated-circuit board, a plurality of service line cards and at least one OAM integrated-circuit board. The exchange integrated-circuit board is used for processing exchange of OAM messages between the OAM integrated-circuit boards and the plurality of service line cards; each service line card is used for processing exchange of OAM messages between the exchange integrated-circuit board and lines; and each OAM integrated-circuit board contains a plurality of OAM processing units and an SW. The SW is used for exchanging OAM messages between the OAM processing units and an intermediate exchange integrated-circuit board. In a down direction, the OAM processing units are used for adding next-hop information in front of the OAM messages, and sending the OAM messages to the exchange integrated-circuit board by means of the SW; and in an up direction, the OAM processing units are used for carrying out OAM processing on the OAM messages from the exchange integrated-circuit board. According to the present invention, the OAM processing capacity of the overall devices is improved, and the OAM stability is improved.

Description

technical field [0001] The invention relates to the field of distributed equipment, in particular to a large-scale OAM detection system and method in distributed equipment. Background technique [0002] IPRAN (Internet Protocol Radio Access Network, IP-based wireless access network) technology is a core network implementation technology for the application scenarios of wireless service backhaul and VIP customer service access. [0003] In a distributed device, in order to detect the connection and disconnection of network services, it is necessary to apply large-scale OAM (Operation Administration and Maintenance, operation, maintenance and management) resources. The traditional implementation method is to install an OAM chip on each line card to perform OAM detection. However, because each line card has a limit on the total resource specification, the resource specification allocated to the OAM chip is often less, and it is difficult to achieve large-scale OAM. application...

The traditional implementation method is to install an OAM chip on each line card to perform OAM detection. However, because each line card has a limit on the total resource specification, the resource specification allocated to the OAM chip is often less, and it is difficult to achieve large-scale OAM. application

Moreover, each line card has an OAM chip, but the services will be assigned to a certain line card. Since the OAM processing capability of each line card is limited, it is difficult to achieve balanced processing of services on multiple line cards, resulting in distributed The business on the card cannot be completely processed by OAM, while the OAM chips of other line cards are idle, which causes the business to not match the OAM processing, and the overall processing capacity is not high

In addition, when the line card of the service station is switched, the processing of the service will also be switched to the OAM chip of the new line card, which will cause OAM to become unstable.
