Abstract: A solution for obtaining an interior gateway protocol IGP domain through division in a network is provided. The network includes an access site link and a non-access site link. The access site link includes a link between access site devices and a link between an access site device and an aggregation site device. The non-access site link includes a link other than the access site link in the network. In this solution, a network device determines a changed access site subgraph based on a change of a network topology of the network, and obtains an IGP domain through division based on a link in the changed access site subgraph. The access site subgraph is one or more connection diagrams formed after the non-access site link is removed from the network topology. This solution can improve efficiency of IGP domain division.

Abstract: The present invention provides a method for receiving information, a method for sending information, and apparatuses for the same. The method for receiving information includes: when a control plane apparatus is capable of managing a forwarding plane apparatus, receiving, by the forwarding plane apparatus, information used for packet forwarding path calculation sent by the control plane apparatus, where the forwarding plane apparatus and the control plane apparatus are located in a network with a network architecture featuring forwarding and control element separation. According to the technical solutions provided in embodiments of the present invention, the forwarding plane apparatus does not need to actively obtain the information used for packet forwarding path calculation before calculating a packet forwarding path based on the information used for packet forwarding path calculation.
