Abstract

The invention discloses a synchronization method between network devices, a network device and a system, belonging to the communication field. The method includes: the first network device establishes an in-band synchronization channel with the second network device in a multi-protocol label switching MPLS-TP network suitable for transmission, the in-band synchronization channel is a data plane channel, and the first The network device and the second network device are included in the same backup group; the first network device sends a first synchronization message to the second network device through the in-band synchronization channel, and the first synchronization message carrying the synchronization information of the first network device, so that the second network device performs synchronization processing according to the synchronization information of the first network device, and the synchronization information of the first network device includes the configuration of the first network device information and / or status information. The invention can realize the synchronization between network devices in the MPLS-TP network without control plane.

Description

technical field [0001] The invention relates to the communication field, in particular to a synchronization method between network devices, network devices and a system. Background technique [0002] In the communication network, network availability is one of the important indicators for operators to pay attention to the communication network. In the communication network, redundant backup between network devices is an important means for operators to improve network availability. Among them, operators can Synchronize between devices to achieve redundant backup between network devices. [0003] At present, the inter-chassis communication protocol (abbreviated as ICCP in English, and the full name in English as Inter-Chassis Communication Protocol) can be used to synchronize between network devices. Used in flat networks. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005]...
