Problems solved by technology

[0014] Aiming at the problems that the increase of inter-board data traffic caused by the transparent transmission of a large number of CCM messages leads to the failure of timely sending and receiving of CCM messages or network vibration, the dedicated protocol processing line card occupies a slot, and the processing of CCM messages occupies a large number of NPU resources. And propose the present invention, for this reason, the present invention aims to provide a kind of transmission method and device of CCM message, to solve at least one of above-mentioned problems

Embodiment Construction

[0036] Functional Overview

[0037] figure 2 It is a system structure diagram for implementing the CCM message processing method of the embodiment of the present invention. Such as figure 2 As shown, by setting a protocol processing card on the main control board, the protocol processing card communicates with the CPU of the main control board and the switching chip; by setting the protocol processing card on the main control board to realize the processing of the CCM message, it can reduce the number of one report The transparent transmission of the text, and does not need a special line card slot to process the CCM message, and does not need the NPU to participate in the message processing. Among them, the main device of the protocol processing card arranged on the main control board is a Field Programmable Gate Array (Field Programmable Gate Array, referred to as FPGA) (that is, the protocol processing module), which is responsible for sending and receiving CCM messages...

Abstract

The invention discloses a transmission method and a transmission device for the continuity check of messages, which are applied to a communication system comprising a line card and a main control board. The method comprises the following steps: the main control board is provided with a protocol processing card, wherein the protocol processing card is used to process the continuity check of the messages; and a switching chip of the main control board sends the messages to the protocol processing card under the condition of receiving the messages from the line card. The transmission method and the transmission device for the continuity check of the messages improve the receiving and sending efficiency of the messages.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for transmitting a Continuity Check Message (Continuity Check Message, CCM for short) message. Background technique [0002] At present, with the increasing application of Ethernet technology in the operation network, higher requirements are put forward for its scalability, reliability, security and manageability. In order to achieve the same service level as the traditional carrier-class transport network, carrier-class Ethernet is used as a new choice for the future transport network. Among them, Operations, Administration, and Maintenance (OAM for short) of Ethernet is a research topic. One of the key points, the main documents about Ethernet OAM are: Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, referred to as IEEE) 802.3ah OAM, IEEE 802.1ag Connectivity Fault Management (Connectivity Fault Managemen...
