Abstract

The invention discloses a system for processing operation and maintenance (OAM) message on a regular basis and a method thereof for sending, receiving and detecting OAM messages. The system comprises a CPU module for creating a dispatch queue list and a detection queue list of OAM messages, a memory module for storing the dispatch queue list and the detection queue list of the OAM messages, and a network processer module for sending and detecting the OAM messages on a regular basis, respectively. The method comprises the following steps: the CPU module writes an OAM template message into the network processor module; and the network processor module reads the OAM messages according to the address information in the OAM template message, sends or detects the OAM messages, and sends an alarming signal to the CPU module according to the detection result. The system and the method carry out the dispatch / detection of messages through the network processor on a regular basis, so as to reduce the load of the CPU, realize the dispatch / detection of messages on a regular basis by using the traffic shaping function of the network processer module, and support mixed dispatch / detection of multiple types of OAM messages with multiple cycles.

Description

technical field [0001] The invention relates to network communication technology, in particular to an OAM message timing processing system and method. Background technique [0002] With the introduction of carrier-grade Ethernet technology, carrier-grade OAM (Operation, Administration, Maintenance) is becoming more and more important. At present, there are many OAM protocols, such as CFM (IEEE P802.1ag, Connectivity Fault Management), TMPLS OAM, etc., which need to regularly send OAM packets, and regularly detect whether the OAM packets sent by the peer end are received. The sending cycle requires a minimum of 3.3ms. When there are multiple protection instances, it is not feasible to allow the CPU to periodically send and detect messages. The CPU load is heavy. [0003] In order to solve the above problems, the present invention proposes a method for implementing timing processing of various OAM messages in combination with a network processor.
