Abstract: A transmission monitoring method and apparatus are provided. The method includes: in a case that an input port of a network node receives M frames, counting the number N of frames sent by an output port of the network node corresponding to the received M frames; in a case that the M is different from the N, determining that frame loss exists in the network node, wherein the M and the N are positive integers. Through the method and apparatus of the present document, the problems of failing to determine a specific device where the frame loss occurs and the construction cost being high are solved, the accuracy and the flexibility of monitoring a position of the frame loss are improved, and the construction cost is reduced.

Abstract: A control method and apparatus for protecting connectivity between Ethernet ring network nodes, and a first node. The control method comprises: the first node supporting an Ethernet ring network protection technology interacting with the second node supporting the Ethernet ring network protection technology and near the first node, to detect link connectivity, where there is at least one third node not supporting the Ethernet ring network protection technology between the first node and the second node, and there is no node supporting the Ethernet ring network protection technology between the first node and the second node; when the first node detects a link fault, blocking a port connecting the first node to a failure link end; the first node sending a link fault alarm protocol frame to other nodes supporting the Ethernet ring network protection technology, to perform protection switchover.

Abstract: An announcement method, apparatus and system are provided. The method includes: an announcement node configuring sending ports of the announcement node in a first region and a second region, wherein, the first region and the second region apply 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 through 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 a situation that the post-switching link state of the first region is inconsistent with a current link state of the second region, the second region needs to perform protection switching and otherwise does not need to perform the protection switching.
