Abstract
A method may include receiving a packet; determining a set of characteristics of the packet; searching a first tree structure for a rule matching the set of characteristics, where the first tree structure stores a first group of rules, and where each of the first group of rules has a first number and a first type of criteria; searching a second tree structure for the rule matching the set of characteristics, where the second tree structure stores a second group of rules, and where each of the second group of rules has a second number and a second type of criteria, where the number and type of criteria of the second group of rules are different at least in part than the number and type of criteria of the first tree structure; and performing an action if the rule matching the set of characteristics is found.
