Claim:
1. A computer-implemented method for determining a type of content for packets of a data network, comprising: receiving an input of a string pattern from a user interface as a parameter for classification; receiving, at a first port of a plurality of ports, a first packet from the data network that is associated with a first session of packets, wherein the first port is configured to receive a plurality of distinctive content types; eliminating at least one potential classification from a group of potential classifications for the first packet without identifying a classification for the first packet associated with the first session; receiving a second packet associated with the first session; determining whether a content type has been determined for the first packet associated with the first session; responsive to the content type of the first packet associated with the first session having been determined, classifying the second packet to be the content type based at least in part on the determined content type without expending further classification resources; responsive to the content type of the first packet not having been determined, classifying the second packet based on the input string pattern without consideration of the at least one identified potential classification that has been eliminated with respect to the first packet and without consideration for identification of the first port; processing data associated with the first session based on the determined content type; and controlling flow of the first session based on the determined content type.
