Node, Another Node, and Methods Performed Thereby for Supporting Domain Name System Over Constrained Application Protocol - A simplified explanation of the abstract

This abstract first appeared for US patent application 18524227 titled 'Node, Another Node, and Methods Performed Thereby for Supporting Domain Name System Over Constrained Application Protocol

Simplified Explanation

The abstract describes a method where a node encodes a DNS query into a CoAP-supported format, sends it to another node supporting both CoAP and DNS protocols, receives a DNS response in CoAP format, and maps it back to DNS format.

  • The node encodes a DNS query into a CoAP-supported format.
  • The encoded query is sent to another node supporting CoAP and DNS protocols.
  • The node receives a DNS response in CoAP format from the other node.
  • The response is mapped back to DNS format based on a mapping scheme.

Potential Applications

This technology could be applied in IoT devices, where CoAP is commonly used for communication, but there is a need to interact with DNS servers for domain name resolution.

Problems Solved

This method solves the problem of nodes that support CoAP but not DNS protocols needing to communicate with DNS servers in a network.

Benefits

- Enables communication between CoAP-supported nodes and DNS servers. - Simplifies the integration of DNS functionality into CoAP-based systems.

Potential Commercial Applications

  • "Integrating DNS Functionality into CoAP Networks for IoT Devices"

Possible Prior Art

There may be prior art related to mapping between different protocols for communication in networks, but specific examples in the context of CoAP and DNS integration would need to be researched further.

Unanswered Questions

How does this method ensure the security of DNS queries and responses transmitted over CoAP?

The abstract does not provide details on the security measures implemented to protect the DNS queries and responses during transmission.

Are there any limitations or constraints when mapping DNS queries and responses to CoAP format?

The abstract does not mention any potential challenges or limitations that may arise during the mapping process between DNS and CoAP formats.


Original Abstract Submitted

A method performed by a node () supporting operation on a Constrained Application Protocol (CoAP), but incapable of supporting operation on a Domain Name System (DNS) protocol. The node () encodes () a DNS query into a first message (), which has a format supported by the CoAP. The DNS query is mapped to the CoAP format of the first message () based on a mapping scheme. The node () then initiates sending () the first message () to another node () operating in the communications network (). The another node () supports operation on the CoAP and on the DNS protocol. The node () finally receives () a second message () from the another node (), which has the format supported by the CoAP. The second message () comprises the DNS response to the sent DNS query. The DNS response is mapped to the CoAP format of the second message () based on the mapping scheme.
