Abstract: This application relates to the field of communications technologies, and discloses a content delivery method, a device, and a system, to resolve an existing problem of traffic chaos in Http redirection. A specific solution includes: receiving, by a first access gateway, a configuration command, and configuring a correspondence between an identifier and a traffic diversion policy according to the configuration command; receiving, by the first access gateway, a first access request, where the first access request carries a first identifier, and the first access request is used to request content to be accessed by a terminal device; when a traffic diversion policy corresponding to the first identifier exists in the correspondence, diverting, by the first access gateway, the first access request to a first server; and receiving, by the first access gateway, content returned by the first server, and sending the content to the terminal device. This application is applied to a content delivery process.

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: 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: 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.
