An announcement method, device and system. The method includes: an announcement node configuring the sending ports of the announcement node in a first region and a second region, the first region and the second region applying different network protection switching technologies; the announcement node acquiring a protection switching request sent from the first region; and the announcement node sending the protection switching request to the second region via the sending port corresponding to the second region, wherein a post-switching link state of the first region is contained in the protection switching request, and under the circumstance that the post-switching link state of the first region is inconsistent with the current link state of the second region, the second region needs to perform protection switching and otherwise need not perform protection switching. This solution solves the problem in the related art that different protection switching technologies cannot perform cooperative processing, prevents the occurrence of a traffic interruption problem caused by different protection switching technologies in networking, and improves the network robustness and stability. |
