1. A method for classifying network connections, comprising the steps of:

  • (A) inspecting a network connection for transmitting a data, wherein the network connection includes a source transmission port and a destination transmission port;

    (B) comparing the source transmission port and the destination transmission port with a transmission port data table of a non-multimedia transmission protocol;

    (C) determining the network connection to be a non-multimedia network connection when any one of the source transmission port and the destination transmission port falls into the transmission port data table of the non-multimedia transmission protocol;

    (D) comparing the source transmission port and the destination transmission port with a transmission port data table of a standard multimedia transmission protocol when any one of the source transmission port and destination transmission port does not fall into the transmission port data table of the non-multimedia transmission protocol;

    (E) determining the network connection to be a multimedia network connection when any one of the source transmission port and the destination transmission port falls into the transmission port data table of the standard multimedia transmission protocol; and

    (F) determining if the network connection is a multimedia network connection according to a transmission history of an application program that opened the network connection when any one of the source transmission port and destination transmission port does not fall into the transmission port data table of the standard multimedia transmission protocol.
