Method and apparatus for addressing in a resource-constrained network
First Claim
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.

Abstract
An electronic device may receive a protocol data unit (PDU) comprising a plurality of addressing bits. Data-link-layer processing of the PDU may be based on each of the addressing bits. Network layer processing of the PDU may be based on a first subset of the plurality of addressing bits. Transport-layer processing of the PDU may be based on a second subset of plurality of addressing bits. The data-link-layer processing may comprise determining whether the PDU is unicast-addressed or non-unicast-addressed. For a unicast-addressed PDU, the data-link-layer processing may comprise determining whether the PDU is destined for the electronic device based on a comparison of a Target ID field of the PDU and a device ID of the electronic device. For a non-unicast-addressed PDU, the Target ID field may not be present, and whether the PDU is destined for the electronic device may be determined based on other criteria.

7. A communication system comprising:
- an electronic device operable to;
receive a protocol data unit (PDU) comprising a plurality of addressing bits;
perform data-link-layer processing of said PDU based on each of said plurality of addressing bits;
perform network layer processing of said PDU based on a first subset of said plurality of addressing bits; and
