Abstract: A co-cable probability detection method, including obtaining information about at least two first events and at least two second events, where the information about the at least two first events is obtained based on a first sounding signal in a first transmission medium, the information about the at least two second events is obtained based on a second sounding signal in a second transmission medium, the information about the first events indicates at least one cable segment on the first transmission medium, and the information about the second events indicates at least one cable segment on the second transmission medium, and obtaining, based on the information about the first events and the second events, a probability that the at least one cable segment on the first transmission medium and the at least one cable segment on the second transmission medium comprise a co-cable segment.

Abstract: This application provides a node configuration method, wherein the method includes: First, determinning a target network based on an original network, where the original network is for flooding control topology information, the target network is for flooding the service topology information, and a quantity of flooding paths in the target network is less than a quantity of flooding paths in the original network. Next, determinning attributes of all interfaces on each node, where the attributes of the interfaces include a first attribute and a second attribute, an interface with the first attribute is configured to flood the service topology information. Further, generating first configuration information based on the attributes of all the interfaces on each node, and sends, to each node, the first configuration information corresponding to each node, where the first configuration information indicates each node to configure the attributes of all the local interfaces.

Abstract: The disclosed apparatuses and methods are directed to data plane restoration in a network. A method comprises receiving a label-switched path (LSP) failure notification indicating a failure in a network; generating, by a node of the network, a fast-restoration (FR) message and transmitting the FR message to a second node of the message forwarding path. The FR message comprises: a plurality of forwarding instruction objects (FIOs) having forwarding instructions for the FR message for each node of a message forwarding path; and a plurality of label-switched path objects (LSPOs) having a restoration LSP data for each node of a protection detour path. Another method comprises receiving the FR message; generating a modified FR message based on the FR message; and transmitting the modified FR message to another node of the message forwarding path based on the FIO, prior to processing the FR message by the node.
