Abstract

The invention provides a method for generating a multi-protocol fault management message based on FPGA. The method comprises the following steps: fault management message related information to be sent by each of a plurality of local maintenance entity group end points is set in the plurality of local maintenance entity group end points separately; and after a sending command of some message type is obtained, the polling process is performed on the plurality of local maintenance entity group end points according to the message type, wherein the polling process comprises the following steps: the message protocol type of the local maintenance entity group end points is obtained; the message protocol type related information is obtained; the message type related information in the protocol type is acquired; and fault management messages of a corresponding number are generated and the fault management messages are outputted according to the message protocol type related information and at least one group of message type related field information. According to the method, CCM, LCK and AIS message sending operations in three protocols including ETH, ITU and IETF can be realized in the FPGA, and the product compatibility and competitiveness can be effectively improved.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a method and system for generating multi-protocol error management messages based on FPGA. Background technique [0002] LMEP (Local Maintenance Entity Group End Point, local maintenance entity endpoint), used for network detection and maintenance. The FM (Fault Management, error management) message is a message used in the local maintenance entity endpoint. Generally, FM messages include CCM (Continuity Check Message, continuity check message) message, AIS (Alarm Indication Signal, alarm indication signal) message, and LCK (Lock, locking signal) message. Among them, the AIS message implements the alarm suppression function, which is used to reduce the number of reported fault alarms. The LCK message implements the locking signal function. CCM packets are used to detect the connectivity status between MEPs (Maintenance Entity Endpoints). Connectivity failures can be caused by...
