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 ...
