Abstract
Systems and methods for generating filtering rules are provided. One computer implemented method includes receiving a command to modify existing network traffic rules. The method further includes performing a quality calculation for the existing network traffic rules, the quality calculation being a function of a number of distinct flows permitted by a particular rule, wherein (i) if the command to the network is to increase the number of rules, then identifying a rule of the existing network traffic rules with a highest quality calculation, splitting the rule into sub-rules and adding a new rule, and (ii) if the command to the network is to decrease the number of rules, then identifying the existing network traffic rules with quality rule calculations near a predetermined value, adding new rules, and merging the new rules to the identified rules with quality rule calculations near the predetermined value.
