Abstract
Embodiments describe a system and/or method for efficient classification of network packets. According to an aspect a method includes describing a packet as a feature vector and mapping the feature vector to a feature space. The method can further include defining a feature prism, classifying the packet relative to the feature prism, and determining if the feature vector matches the feature prism. If the feature vector matches the feature prism the packet is passed to a data recipient, if not, the packet is blocked. Another embodiment is an apparatus that includes an identification component that defines at least one feature of a packet and a classification component that classifies the packet based at least in part upon the at least one defined feature.
