  • a software stack operable to process a first set of TCP packet streams; and

    a hardware stack, in parallel with and communicatively coupled to the software stack, operable to process a second set of TCP packet streams different from the first set of TCP packet streams,wherein the software stack is operable to offload one or more TCP connections from the software stack to the hardware stack for processing by the hardware stack instead of by the software stack,wherein the hardware stack is operable to upload one or more TCP connections from the hardware stack to the software stack for processing by the software stack instead of by the hardware stack, andwherein the software stack and the hardware stack are operable to process packets corresponding to different respective TCP connections in parallel.
