Abstract: A packet processing method includes determining, by a node in a first network, a transmission path for a packet, where the transmission path includes a path in the first network and a path traversing a second network; adding, by the node, path information to the packet based on the transmission path, where the path information includes traversal indication information, and the traversal indication information indicates an ingress node in the second network to encapsulate and transmit the packet based on an egress node that is specified in the traversal indication information and that is located in the second network; and sending, by the node to the ingress node in the second network through the first network, the packet to which the traversal indication information is added.

Abstract: Embodiments of the present invention disclose a path determining method, apparatus, and system. In a hybrid network including one controller for implementing a control function, the controller may separately obtain network topology information of a first network and a second network of different network types by using a same control channel protocol. When the controller obtains a path determining requirement for the data transmission path, because the controller has the network topology information of the first network and the second network, during computation of the data transmission path, the controller can determine a path computation result including transmission path parts of the first network and the second network, without performing additional information exchange with another device, and send the path computation result to the first network device. In this way, planning efficiency of the data transmission path is improved.

Abstract: A packet sending method includes obtaining, by a client device, an Internet Protocol (IP) anycast address of the anycast server cluster and an IP unicast address of the target server, generating, by the client device, an IP detection packet, where the IP detection packet is used to detect whether the target server is reachable based on the IP anycast address, and the IP detection packet includes the IP anycast address and the IP unicast address of the target server, and instructs the target server to replace the IP unicast address of the target server with the IP anycast address, and sending, by the client device, the IP detection packet to the target server.

Abstract: Embodiments of the present invention provide a Flow Specification-based communications method, device, and system. The method includes: obtaining, by a controller, a requirement indicating that a first resource on a forwarding device needs to be associated with a second resource on the forwarding device; and sending, by the controller, a Border Gateway Protocol Flow Specification BGP Flow Spec protocol packet according to the requirement, where the BGP Flow Spec protocol packet includes a network layer reachability information field and an extended community attribute field, the network layer reachability information field carries characteristic information of the first resource, the extended community attribute field carries a global identifier GID used to indicate the second resource, and the BGP Flow Spec protocol packet is used to instruct to associate the first resource with the second resource.
