Embodiment Construction

[0040] An automatic protection method for an optical fiber link based on the APS protocol provided by the present invention includes the following steps: the source node of the optical fiber link encapsulates the APS protocol information of the optical fiber link channel to be protected into an Ethernet overhead frame and sends it to the optical fiber link The sink node of the optical fiber link receives the Ethernet overhead frame and parses out the APS protocol information, and then sends it to the corresponding channel. After the protection switching occurs, the source node becomes the sink node, and the sink node becomes the source node, and the automatic protection is realized in the same manner as above. The method has good expansibility, high reliability and can effectively reduce the number of buses. The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Abstract

The invention discloses an automatic optical fiber link protection method based on an APS protocol. The automatic optical fiber link protection method comprises the steps that a source node of an optical fiber link enables APS protocol information of an optical link channel in need of protection to be packaged into an Ethernet overhead frame, the Ethernet overhead frame is sent to a destination node of the optical fiber link, and the destination node of the optical fiber link receives the Ethernet overhead frame and analyzes out the APS protocol information. The invention further provides an automatic optical fiber link protection system based on the APS protocol. The system comprises a configuration unit, a cache unit, a packaging unit, a sending unit, a receiving unit and an analyzing unit. By the adoption of the automatic optical fiber link protection method and system, the expansibility is enhanced, the interference resistance and the reliability are improved and meanwhile the number of single-disk overhead buses is reduced.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to an automatic protection method and system for an optical fiber link based on an Automatic Protection Switching (APS, Automatic Protection Switching) protocol. Background technique [0002] At present, the optical fiber communication network has become the main part of the information infrastructure of the national economy. Once the optical fiber communication network is blocked, it will have a great impact on the society and cause huge economic losses to the society. In order to ensure that the optical fiber communication line can quickly restore the optical fiber line when it is blocked, and ensure normal communication, the optical fiber automatic switching protection technology is usually used, that is, when the transmission of the working link is interrupted or the performance is degraded to a certain extent, the fault is detected in time and quickly and automatically...
