Disclosed are a link recovery method and corresponding network devices. The method comprises: a first device detecting that a data message between the first device and a second device is lost and then the first device sending a first recovery negotiation message to the second device; the first device determining whether a negotiation response message sent by the second device is received or not in a pre-set first time range. If the negotiation response message of the second device is not received, the first device sends an extra recovery negotiation message to the second device in a pre-set second time range until the first device receives the negotiation response message from the second device, wherein the values of time-out time fields in the recovery negotiation message which is sent a plurality of times are different. After receiving the negotiation response message, the first device recovers data link communication with the second device. According to the embodiment in the invention, the recovery negotiation message is sent a plurality of times and the values of time-out time fields capable of being modified in two successive recovery negotiation messages are set to different values, so that the time of re-negotiating after an LACP protocol has a fault can be shortened, a communication interrupt time delay is kept to a millisecond level and the requirements of telecommunication operations are met. |
