1. A method performed by an electronic device, the method comprising:

  • receiving a protocol data unit (PDU) comprising a plurality of addressing bits;

    performing data-link-layer processing of said PDU based on each of said plurality of addressing bits;

    performing network layer processing of said PDU based on a first subset of said plurality of addressing bits; and

    performing transport-layer processing of said PDU based on a second subset of said plurality of addressing bits; and

    wherein said data-link-layer processing of said PDU comprises determining whether said PDU is a unicast-addressed PDU or non-unicast-addressed PDU; and

    wherein, in instances that said PDU is a unicast-addressed PDU, said data-link-layer processing comprises determining whether said PDU is destined for said electronic device based on a comparison of a Target ID field of said PDU and a device ID of said electronic device; and

    wherein, in instances that said PDU is a non-unicast-addressed PDU, said Target ID field is not present in said PDU and whether said PDU is destined for said electronic device is determined based on criteria other than a device ID of said electronic device.
