1. A method for determining a type of content, comprising:

  • receiving a first packet of a session;

    determining an unknown state classification with regard to a potential classification for the session based on a determined unknown state classification with regard to the potential classification for the first packet;

    receiving a second packet of the session;

    determining a known state of classification with regard to the potential classification for the session based at least in part on the determined unknown state with regard to the potential classification for the first packet and on a determined known state classification with regard to the potential classification for the second packet; and

    wherein;

    the determined state of classification of the first packet further indicates that the first packet and the session have been determined not to be an other state of classification; and

    the state of classification for the second packet is determined by eliminating the other state of classification as a potential classification candidate for the second packet.
