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.

Abstract: An entry adding method includes: a switch receives a first group entry sent by a controller, where the first group entry includes importance indication information of the first group entry, and a first action bucket; the switch determines that the first group entry cannot be added to a group table, and that a second group entry exits in the group table, the switch deletes the second group entry and adds the first group entry to the group table. Where importance of the second group entry is lower than importance of the first group entry; the second group entry includes a second action bucket; a quantity of first action buckets is not greater than the sum of a first value and a quantity of second action buckets; and the first value is a quantity of available action buckets in the group table.

Abstract: The present application provides a packet processing method, device and system. With the present application, timely processing can be performed on a received packet according to an added first flow table entry, so that the timely processing can be implemented for a flow whose importance is high, and the problem in the prior art that a forwarding device cannot add a new flow table entry to a flow table because all flow table entry resources are in use can be relieved, thereby improving the reliability of packet processing.
