Abstract: Embodiments of this application relate to the field of communication technologies, and provide a routing information publishing method. The method includes: An edge transport device connected to a first edge device in a first network domain receives, based on a control plane protocol message, first routing information that is from a controller and that includes an address of a second edge device in a second network domain and a destination address of the second network domain, and sends the first routing information to the first edge device, so that the first edge device generates, based on the first routing information, a forwarding table that is of the first edge device and that is used to indicate a forwarding relationship between the first network domain and the second network domain.

Abstract: A path protection method includes receiving, by a source node of a first path, a path event notify message from a first node on the first path. The path event notify message includes indication information that the first path is predicted to fail. The path protection method further includes obtaining, by the source node, information about a predicted protection path. The information about the predicted protection path includes resource information of a second path useable to protect a service on the first path. The first path and the second path include the source node and a same sink node. The path protection method further includes storing, by the source node, the resource information of the second path.
