Hardware invariant protocol disruptive interference

We consider that the target of intentional interference is a communication channel and we attempt to find interference capable of degrading communication throughput. The goal is to achieve disruption independent of hardware implementation while maintaining hardware functionality. We call such interference HIPDI (hardware invariant protocol disruptive interference) and parameterize it using a concept called hardware aperture, as defined by the protocol of the channel. We show that simple CW and AM interference is capable of halting throughput for 100BaseTX Ethernet networks for all hardware configurations considered.
