System, apparatus and method for transmitting and receiving check information message continuously

Abstract

The invention discloses a system for realizing the continuous check of the sending and receiving of messages, and a device and a method thereof, wherein, the system comprises a main control module and a plurality of blocks of line cards, one block of the line cards is appointed as the protocol processing line card, namely, the device, wherein, other line cards except the protocol processing line card send the received messages to the main control module; the main control module then sends the messages received from other line cards to the protocol processing line card for processing and sends the messages sent by the protocol processing line card to the appointed ports of other line cards to be sent to the opposite ports; after constructing a maintenance association MA entity, the protocol processing line card is initialized and written into the table item of the continuity check message CCM information table to carry out the sending and receiving processing of the CCM messages and the corresponding processing of message errors or connection errors. The invention leads the CCM messages to be centralized on the protocol processing line card for processing so as to save the CPU resources of other line cards, and supports the sending and receiving processing of large capacity CCM messages.

Description

technical field [0001] The present invention relates to Ethernet operation, maintenance and management (OAM, Operations, Administration and Maintenance) technology, in particular to the sending and receiving of the continuity check message (CCM, Continuity Check Message) message of Ethernet connectivity fault management (CFM, Connectivity Fault Management) systems, devices and methods. Background technique [0002] Ethernet technology has been widely used due to its good economy, interoperability and ease of use. At present, Ethernet is gradually developing into metropolitan area network and wide area network, so as to provide multi-service bearer as a carrier-class transport network technology. With the increasing application of Ethernet technology in operational networks, challenges are constantly being raised to its scalability, reliability, security and manageability. In order to achieve the same level of service as the traditional carrier-class transport network, vari...

Problems solved by technology

Although the packet can be processed in this line card by doing so, it greatly wastes the CPU resources of the line card.

Currently, new technologies and applications are emerging one after another, and the protocols and tasks that need to be processed by the CPU of the line card are becoming more and more heavy, and the CCM message is a fast message at the millisecond level, which supports the sending and receiving of large-capacity CCM messages. The CPU of the card is a very heavy task, so this processing method not only makes the CPU of the line card overwhelmed, but also cannot realize the sending and receiving of large-capacity CCM messages, thus limiting the application of the Ethernet CFM protocol
