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: This application discloses a policy conflict resolution method which includes receiving a first control policy and decomposing the first control policy into m first rules, and receiving a second control policy and decomposing the second control policy into n second rules. The method also includes performing negation on each first rule to obtain a first negation rule, performing negation on each second rule to obtain a second negation rule, and generating a corresponding first execution rule by using each first negation rule and each second negation rule according to a rule synthesis principle. Additionally, the method includes deleting an invalid rule, using a remaining one of the first execution rules as a valid first execution rule, performing negation on each valid first execution rule, and converting, according to a protocol supported by a first forwarding device, each valid first execution rule on which negation has been performed into a corresponding forwarding entry of the first forwarding device.
