Abstract：Firewall conflict detection algorithm is a classical algorithm for the rule set of firewall filtering,which could effectively improve the efficiency of the firewall rule set and reduce the conflict between the rules,so as to save a lot of computing resources and ensure the normal operation of the network communication.However,with the rapid growth of data size and the number of users,the original conflict detection algorithm has been unable to meet the current network communication needs because the firewall rule set is also increasing,so the improvement is essential.This paper proposes to combine the default rules and the collision detection algorithm,and improve the pre optimization before detection.At the same time,the default rule is analyzed and combined with the original rule set,which greatly improves the matching efficiency of the firewall and shortens the processing delay of the firewall.
