Inbound packets received by a physical network adapter of a processing device are routed by evaluating an inbound frame to determine if an inbound frame destination MAC address is associated with the processing device and determining whether the inbound frame should be routed to a corresponding logical interface or to drop the inbound frame if the inbound frame destination MAC address is equal to a virtual MAC address supported by the processing device. If it is determined that the inbound frame should be routed to the corresponding logical interface, then any necessary layer 3 functions are performed and the inbound frame is routed to the corresponding logical interface, thereby combining both layer 2 and layer 3 routing into a single logical function.

A method and implementation for communicating between logic functions using non-metallic coupling between logic functions on a same chip or separate chip is shown. For communication on the same chip, radiated energy from an antenna coupled to a transmitting logic function is coupled to a receiving antenna and then coupled by an electrical connection to a receiving logic function. Communication between USLI chips mounted on a module is performed by coupling an RF signal from a first chip to a μ-satellite mounted within the module and then coupling the RF signal from the satellite to a second chip. Communication can also be formed between the satellite and different logical functions on the same USLI chip.
