Abstract: The present application discloses data processing methods. Example methods include obtaining information about a header field of a data packet and searching an exact match flow table for an exact match entry that matches the data packet. When the matching exact match is found, a determination is made as to whether an update time of a wildcard entry corresponding to the exact match entry is before a creation time of the exact match entry. In response to determining that the update time is before the creation time of the exact match entry, the data packet is processed according to an action instruction corresponding to the exact match entry. In response to determining that the update time of the wildcard entry corresponding to the exact match entry is not before the creation time of the exact match entry, the exact match entry is deleted.

Abstract: This application discloses a network slicing method. The method includes obtaining metadata information of each of multiple traffic flows, determining a classification policy according to metadata information of the multiple traffic flows, determining a network slicing policy according to the classification policy, and the network slicing policy includes a mapping relationship between a traffic flow type and a network slice and a slice weight of the network slice, and determining a resource node policy according to the network slicing policy, where the resource node policy includes a mapping relationship between at least one resource node in the network and the at least one network slice and a resource weight of each resource node, and the resource weight of the resource node indicates a ratio of a resource of each of network slices corresponding to the resource node to a resource of the resource node.

Abstract: A network communication method, a device, and an Internet system are presented. The method includes receiving, by a first primary node at a first network layer, first communication information sent, by a non-primary node that initiates communication, to a non-primary node that receives communication, where the non-primary node that initiates communication is in a domain to which the first primary node belongs, and the non-primary node that receives communication is in a different domain at the first network layer; determining, first label information, where the first label information is used to indicate a communication path, at a second network layer, from a node that receives the first communication information to a node that has a mapping relationship with a second primary node to which the non-primary node that receives communication belongs; and sending, first information to a node at the second network layer.

Abstract: A link state packet transmission method and a routing node are disclosed. The method is applied to a tree topology, where the tree topology includes a leaf routing node, an intermediate routing node, and a root routing node. The method includes: receiving, by the intermediate routing node, a link state packet sent by a child routing node of the intermediate routing node; sending, by the intermediate routing node, the link state packet to the root routing node, where the root routing node is configured to aggregate received link state packets to obtain a link state packet set; receiving, by the intermediate routing node, the link state packet set sent by the root routing node; and sending, by the intermediate routing node, the link state packet set to the child routing node of the intermediate routing node.
