1. An integrated circuit for facilitating data communication between two network nodes, said integrated circuit being configured to be associated with a first network node of said two network nodes and disposed in a data communication path between said two network nodes during said data communication, comprising:

  • an embedded processor for performing a first plurality of TCP acceleration functions for packets sent from said first network node to a second one of said two network nodes and for performing a first plurality of security functions for said packets;

    at least one network processor for performing a second plurality of said TCP acceleration functions for said packets and for performing a second plurality of said security functions for said packets, said second plurality of said TCP acceleration functions being different from said first plurality of said TCP acceleration functions, said second plurality of said security functions being different from said first plurality of said security functions;

    hardware circuitry for performing a third plurality of said TCP acceleration functions for said packets and for performing a third plurality of said security functions for said packets, said third plurality of said TCP acceleration functions being different from said second plurality of said TCP acceleration functions and said first plurality of said TCP acceleration functions, said third plurality of said security functions being different from said second plurality of said security functions and said first plurality of said security functions, wherein said packets traverse said embedded processor, then said at least one network processor, and then said hardware circuitry in a substantially inline manner during said data communication from said first network node to said second network node.
