Abstract
Described herein are systems, methods, and apparatuses for device communication over IP. In some embodiments, IPv6 addresses are compressed into ISO/IEC 14908-1 addresses, and use leading zero suppression to compress the headers. In some embodiments, IPv4 the least significant two bytes of the IPv4 address are used as an ISO/IEC 14908-1 subnet and node number.
Claims10
A method comprising:
- receiving a first packet at a mapping logic, wherein the first packet comprise a source Control Network Protocol (“CNP”) address and a destination CNP address;
- determining a source IP address of the sender of the first packet from the source CNP address;
- determining a destination IP address for the first packet;
- forming a second packet without including the destination CNP address, wherein the second packet comprises the source IP address formed from the source CNP address, the destination IP address, and a payload that consists the source CNP address and an original payload of the first packet.
1 more element
An apparatus comprising:
- a processor;
- and
- memory to store mapping logic instructions, which when executed by the processor to cause the processor to:
- receive a first packet, wherein the first packet comprise a source Control Network Protocol (“CNP”) address and a destination CNP address,
- determine a source IP address of the sender of the first packet from the source CNP address,
- determine a destination IP address for the first packet,
- form a second packet without including the destination CNP address, wherein the second packet comprises the source IP address formed from the source CNP address, the destination IP address, and a payload that consists the source CNP address and an original payload of the first packet.
