Abstract: The application provide a packet sending method, a router, and a service switching entity. According to the application, a router determines a flow group identifier of a service packet and information about a next-hop service switching entity according to a user identifier and IP 5-tuple information; and forwards the packet to the next-hop service switching entity according to the information about the next-hop service switching entity, so that the next-hop service switching entity determines a corresponding destination service instance according to the user identifier, the flow group identifier, a router identifier, and a processing result, and forwards the packet to the destination service instance, to perform corresponding service processing, thereby implementing service packet forwarding among service instances. The router in the method provided in the embodiments has a flow steering function, and steers a flow to a specified path to perform node-by-node processing.

Abstract: A network device obtains, from a transaction queue, a plurality of transactions that do not conflict with each other, and performs reverse shallow copying in parallel for the transactions that do not conflict, to generate a plurality of temporary trees corresponding to the plurality of transactions. Because the plurality of transactions does not conflict with each other, processing the transactions in parallel can ensure accurate and proper transaction processing. In addition, generating the temporary trees in a reverse shallow copying manner can effectively reduce consumption of time and memory. Further, processing of the plurality of transactions is implemented by merging the plurality of temporary trees.

Abstract: A multi-level flow table search method includes extracting matching information of a data packet when the data packet is received and selecting a keyword from the matching information of the data packet according to flow-table match-field configuration information. The method also includes searching for a match field of each-level flow table in a multi-level flow table starting from a first-level flow table in the multi-level flow table by using the keyword as a search keyword, and matching the search keyword with the match field. If matching of a match field of a current-level flow table is completed, the method includes executing a corresponding instruction, and if the current-level flow table is not a last-level flow table or there is an instruction for executing an action, executing a corresponding action.
