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.

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.
