Abstract: A method includes: interacting, by a first device, with a user through an application in a data collection range; after determining that the user is not located in the data collection range, determining, by the first device, that the user is located in a data collection range of a second device in a network; and sending, by the first device, to-be-migrated data to the second device, so that the second device continues to interact with the user based on the to-be-migrated data. The second device supports the application, the to-be-migrated data includes information about the application and progress information, and the progress information indicates progress of interaction between the first device and the user.

Abstract: The method includes: forwarding, based on path sets of nodes in a network, service data between a source node and a sink node in the network, where the path sets of the nodes in the network are determined by iteratively performing the following path set determining step: for each link in the network, obtaining a path set of a start node of the link, and determining N shortest paths from an end node of the link to the sink node; and for each path included in the path set of the start node, determining, according to the N shortest paths, the path, and the link, to add a new path formed by the path and the link into a path set of the end node.
