Problems solved by technology

If the state machine is not migrated to the board where other member ports are located in time, the local device and the peer device will report a CCM timeout alarm. We can artificially suppress the timeout alarm of the local device, but the timeout alarm of the peer device is normal. then out of control

Abstract

The invention provides a method and device for transmitting messages. An aggregated link trunk is set between a first device and a second device. A state machine of a maintenance association end point(MEP) of the first device is currently located on a first single board of the first device. The level of the MEP of the first device is different from that of the MEP of the second device. The methodcomprises the steps that when the state machine of the MEP of the first device is migrated from the first single board to a second single board of the first device, the first device suppresses faultalarm and sends an alarm indication signal (AIS) to the second device according to a preset frequency; and when the state machine of the MEP of the first device is migrated completely from the first single board to the second single board of the first device, the first device recovers the fault alarm and stops sending the AIS. The false alarm resulting from state machine migration timeout is effectively suppressed through utilization of the alarm indication signal (AIS). The method and the device are simple and feasible. Interconnection is not influenced.

Description

technical field [0001] The embodiments of the present invention relate to the field of communications, and more specifically, to a method and device for transmitting messages. Background technique [0002] The fault management function in Ethernet is mainly to detect faults by periodically sending Continuity Check Messages ("CCM"), and the Maintenance Association End Point ("MEP") at the opposite end will be sent within 3.5 cycles. If the CCM is not received, report the CCM timeout. [0003] The sending frequency of CCM is, for example, 3.3ms -1 、10ms -1 , 100ms -1 、1s -1 、10s -1 、1min -1 and 10min -1 , where 3.3ms and 10ms are mainly used for link protection switching, and the sending frequency above 100ms is mainly used for link performance monitoring. The sending frequency of CCM is very demanding on the performance of the equipment, especially 3.3ms -1 and 10ms -1 CCM transmit detection and receive detection. The soft forwarding method is basically impossible ...
