Claim:
1. A method for determining a type of content, comprising: receiving a first packet of a session with which the first packet is associated, the first packet received in a data classification module via a communication interface coupled to a network link; determining, in the data classification module, a potential state of classification for the first packet of the session, a determined potential classification indicating that at least one classification candidate has been ruled out; receiving a second packet of the session, the second packet received in the data classification module via the communication interface coupled to the network link; determining, in the data classification module, a content type for the second packet based at least in part on the determined potential state of classification for the first packet of the session without consideration of the at least one classification candidate that has been ruled out; and wherein packets associated with the session are transmitted by a sender via a data network to which the network link is connected to a receiver and at least the first and second packets are processed by the data classification module after transmission by the sender and prior to receipt by the receiver.
