Problems solved by technology

At present, when configuring OAM, there may be some damaged tunnels due to network management configuration problems or other abnormal handling, and the damaged tunnel happens to be the same as the outgoing label of the tunnel where the OAM is located. Therefore, the local MEP (MEG (MaintenanceEntity Group, maintenance entity )End Point, maintenance joint endpoint) when receiving the CCM (Continuity Check Message) message of the damaged tunnel, the remote MEGID carried by it is different from the MEGID of the local end, which will cause the normal tunnel to generate MMG ( Wrong merging alarms, unexpected MEG Mismerge) alarms cannot trigger protection switching, resulting in service interruption
Of course, if there are several tunnels, you can check them one by one through the network management system or CLI (command-line interface). The performance is not high enough to meet the requirements of rapid service recovery on the live network
[0003] In addition, FPGAs can be used to implement OAM functions in current PTN equipment. However, current FPGA resources are limited and cannot provide enough resources to store all OAM information at the same time.
In order to meet the demand for sufficient FPGA logic resources, if you switch to an FPGA with more resources, you will need more funds; if you add peripherals, the hardware design risk is high, and poor stability is not advisable.

Abstract

The invention discloses an alarm method and device, comprising: polling and reading the saved OAMID, if the read OAMID generates an MMG alarm, then write the read OAMID to a register designated by the FPGA, and an OAMID uniquely identifies a piece of OAM information ; Go to the latch register address of the FPGA to read the remote MEGID information according to the OAMID saved in the register; report the MMG alarm and the remote MEGID information. In this way, by carrying the remote MEGID information when reporting the MMG alarm, it is convenient for the network management to quickly find out which damaged tunnel caused the OAM of the normal tunnel to generate the MMG alarm, so that the alarm can be quickly processed and the normal tunnel service can be restored as soon as possible. The OAMID of the MMG alarm is written to the FPGA instead of writing all the OAMIDs to the FPGA, which saves a lot of FPGA logic resources.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to PTN (Package Transport Network, packet transport network)-OAM (Operation Administration and Maintenance, operation, management and maintenance) technical field, and more specifically relate to an alarm method and device. Background technique [0002] With the development of carrier-class Ethernet technology, PTN has been widely used as a transmission network, and OAM has become more and more common as a means of detecting network faults. In order to prevent service interruption caused by a link failure, PTN deployment needs to configure protection switching to ensure that services on a link failure can be switched to work on a normal link. However, OAM must be configured for protection switching. At present, when configuring OAM, there may be some damaged tunnels due to network management configuration problems or other abnormal handling, and the damaged tunnel happens to be the same...
