Abstract
The techniques disclosed herein enable systems to enhance network packet processing functionality through an accelerated packet classifier algorithm. Network packet classifiers serve to evaluate characteristics of network packets against various rules to determine how to process the network packet (e.g., routing, rewriting data). In contrast to existing systems, the present techniques pack a plurality of rules into a rule set which can then be applied to a network packet as a cohesive unit. By leveraging characteristics of binary arithmetic, the network packet classifier can evaluate the network packet against multiple rules in parallel. For example, the network packet classifier can concurrently compare values encoded by the network packet against a plurality of target ranges defined by the rules. This enables the network packet classifier to complete a full rule set evaluation within a single pass of the network packet thereby improving computing efficiency.
