Abstract
A system for data communication between electronic devices comprises a first electronic device that is a resource-constrained device; and a second electronic device that exchanges data with the first electronic device. One of the first electronic device and the second electronic device generates a message in a data unit frame complying with a protocol stack that includes a Constrained Application Protocol (CoAP) message on a data link layer in the absence of a User Datagram Protocol (UDP) layer.
Claims19
A system for data communication between electronic devices comprising:
- a first electronic device that is a resource-constrained device;
- and
- a second electronic device that exchanges data with the first electronic device, wherein:
- one of the first electronic device and the second electronic device generates a message in a data unit frame complying with a protocol stack that includes a Constrained Application Protocol message on a data link layer in the absence of a User Datagram Protocol (UDP) layer.
An electronic device comprising:
- circuitry configured to:
- generate and transmit a message in a data unit frame complying with a protocol stack that includes a Constrained Application Protocol (CoAP) payload directly on a data link layer;
- and
- provide a security protocol at the data link layer in the absence of a network layer;
- wherein the data unit frame includes an Ethertype field that indicates that a proprietary CoAP over Local Area Network (CoAPOL) protocol is encapsulated in the payload of the data unit frame, wherein the CoAPOL protocol operates at Layer 2 Ethernet.
A communication system for securely communicating data packets between a first device and a second device, the communication system comprising:
- a first network complying with a first communication protocol;
- a first device being configured to communicate via the first network with other devices in communication with the first network, the first device being configured to generate a message in a data unit frame complying with a protocol stack that includes a Constrained Application Protocol (CoAP) payload directly on a data link layer;
- a second network being based on a second communication protocol;
- a second device being configured to generate a message complying with the second communication protocol;
- and
- a computing device storing and executing an application that facilitates a data exchange between the first communication protocol and the second communication protocol;
- wherein the data unit frame includes an Ethertype field that indicates that a proprietary CoAP over Local Area Network (CoAPOL) protocol is encapsulated in the payload of the data unit frame, wherein the CoAPOL protocol operates at Layer 2 Ethernet.
