Abstract: An entity establishment processing method and an apparatus are provided. The processing method includes: A terminal side device receives first indication information from a first network side device, where the first indication information is used to trigger reestablishment of a first PDCP entity of the terminal side device. When a first bearer corresponding to the first PDCP entity is not a radio bearer used to perform duplication transmission between the terminal side device and a core network side device, in a process in which the terminal side device reestablishes the first PDCP entity based on the first indication information, the terminal side device sets a parameter of the first PDCP entity to an initial value.

Abstract: Various embodiments provide a packet transmission method and an apparatus. In those embodiments, a first device supports a first protocol layer, and replicates a packet at the first protocol layer. A second device supports a second protocol layer, and deduplicates the packet at the second protocol layer. When receiving a first packet, a first access device converts a sequence number of the first protocol layer in the first packet into a sequence number of the second protocol layer, and then sends, to the second device, a second packet that carries the sequence number of the second protocol layer and a data packet of the first packet. For example, if the first access network device receives two packets having same data packets, the first access network device separately coverts sequence numbers in the two packets without performing operations of first deduplicating and then replicating the packet.

Abstract: Embodiments of the present disclosure disclose an SDN-based ARP implementation method and apparatus. The method includes: receiving, by a controller, an ARP request sent by a first switch, and when it is determined that no ARP entry corresponding to the ARP request exists locally, sending, to the first switch, an instruction configured to instruct the first switch to flood the ARP request. In this way, the ARP request can be broadcast to an entire network by means of message forwarding between switches.

The method includes: sending, by a control plane network element, a notification message to an infrastructure controller, the notification message includes at least one forwarding identifier corresponding to a user service flow and includes an identifier of a target forwarding plane network element providing service processing for the user service flow; the notification message is used to instruct the infrastructure controller to determine a first forwarding rule including the at least one forwarding identifier and the identifier of the target forwarding plane network element and send the first forwarding rule to an infrastructure forwarder controlled by the infrastructure controller. The present invention is used for service flow forwarding, resolves a problem that flexibility of service flow forwarding is relatively low, and achieves an effect of improving flexibility of service flow forwarding.
