Abstract:
1. An apparatus for handling first and second digital electronic flows, wherein the first flow comprises a plurality of first datagrams, wherein the first datagrams include datagram header information and datagram payload information, wherein at least one of the first datagrams contains application layer payload information, wherein the second flow comprises a plurality of second datagrams, wherein the second datagrams include datagram header information and datagram payload information, and wherein at least one of the second datagrams contains application layer payload information, the apparatus comprising: a network interface through which at least some of the first datagrams and at least some of the second datagrams pass; a plurality of processing components; and a flow identification and classification subsystem that inspects at least some of the first datagrams and based on at least in part on datagram header information and application layer payload information of the first datagrams causes a first flow policy to be applied to the first flow such that at least some of first datagrams of the first flow take a first path through the plurality of processing components of the apparatus, and wherein the flow identification and classification subsystem inspects at least some of the second datagrams and based on at least in part on datagram header information and application layer payload information of the second datagrams causes a second flow policy to be applied to the second flow such that at least some of second datagrams of the second flow take a second path through the plurality of processing components of the apparatus, wherein the flow identification and classification subsystem classifies a plurality of transmitted information and thereby determines that a third flow policy will be used to process a forward portion of a third flow, and thereby determines that a fourth flow policy will be used to process a return portion of the third flow.
