Embodiment Construction

[0026] In the traditional technology, when the protection path transmits service packets, even if the working path recovers from failure, only a small amount of other packets can be temporarily transmitted before the bit error alarm is released. For example, it is stipulated in the multi-protocol label switching (multi-protocollabel switching, MPLS) Y.1731 protocol that when a bit error occurs on the working tunnel (tunnel) and service packets are switched to the protection tunnel, the working tunnel can receive operations with a lower rate, Management and maintenance (operation, administration, maintenance, OAM) message, where the OAM message is a message without error codes. For example, the rate is 100 packets per second.

[0027] In order to avoid frequent switching between paths, it is necessary to receive at least a certain number of error-free packets continuously before clearing the bit error alarm, so that service packets can be switched back to the working path from ...

Abstract

Disclosed are a communication method, device and system, and a storage medium, which are used for reducing the time for removing an error code alarm and reducing the risk of service damage. The methodcomprises the following steps: a first network device determines that an entry rate of a first port is less than or equal to a first threshold, and the first network device is connected with a secondnetwork device through the first port; the first network device sends a first operation, management and maintenance OAM message to the second network device, the first OAM message comprises first information, and the first information is used for indicating the second network device to send a test message to the first network device; and the first network device receives the test message sent bythe second network device through the first port.

Description

technical field [0001] The present application relates to the field of network communication, and in particular to a communication method, device, system and storage medium. Background technique [0002] In order to ensure the normal transmission of service packets, besides a working path, a protection path is set between devices. Normally, service packets are transmitted through the working path. When a bit error fault occurs on the working path, the network device issues a bit error alarm, and the service transmission path is switched from the working path to the protection path. When the working path returns to normal and the alarm is cleared, the service transmission path is switched from the protection path to the working path, and the working path transmits service packets. Usually, the condition for releasing the bit error alarm is to receive a certain number of error-free packets continuously. [0003] Before the service transmission path is switched from the prot...
