Claim 14:
15. 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.
