Hi authors,

I was going through the draft. I looked at section 2.3 that CoAP provides best of both worlds by choosing between Confirmable and Non-confirmable messages. This only true if CoAP is used over UDP. If CoAP is used over TCP/TLS etc. as defined in RFC 8323 then Confirmable/Non-confirmable does not really have any affect. So is the draft trying to do streaming over CoAP+UDP?

Do you have some performance results that show significant benefits of using CoAP instead of RTP or HTTP?

Dear list,
A new draft has been submitted which essentially tries to facilitate real-time live FPV feeds with high QoE over the Internet under constrained environments. The technology leverages on some of the advantages of CoAP and proposes few extensions so that CoAP can have an efficient way of real-time streaming for the 'Things' version of Internet (I mean IoT), just like HTTP has HTTP-streaming in conventional Internet. So, we can have a protocol which is equally efficient in sending small sensor data as well as streams which may contain video information. This draft is an outcome of the experiments and implementations that we carried out on the face of some real-life challenges faced in robotic and UAV based AR applications.

Comments are welcome.

Dear chairs,
If you may please allow us to present, then we can try to explain the concept in physical meetings and also show some visuals from the demo that we had and the benchmark results. Looking forward.

Please note: an extended version of this draft has been accepted to be presented in Wi-UAV workshop of Globecom in coming December.

Abstract:
   This draft presents extensions to Constrained Application Protocol
   (CoAP) to enable RESTful Real-time Live Streaming for improving the
   Quality of Experience (QoE) for delay-sensitive Internet of Things
   (IoT) applications. The overall architecture is termed ''Adaptive
   RESTful Real-time Live Streaming for Things (A-REaLiST)''. It is
   particularly designed for applications which rely on real-time
   augmented vision through live First Person View (FPV) feed from
   constrained remote agents like Unmanned Aerial Vehicle (UAV), etc.
   These extensions provide the necessary hooks to help solution
   designers ensure low-latency transfer of streams and, for contents
   like video, a quick recovery from freeze and corruption without
   incurring undue lag. A-REaLiST is an attempt to provide an
   integrated approach to maintain the balance amongst QoE, resource-
   efficiency and loss resilience. It provides the necessary hooks to
   optimize system performance by leveraging contextual intelligence
   inferred from instantaneous information segments in flight. These
   extensions equip CoAP with a standard for efficient RESTful
   streaming for Internet of Things (IoT) contrary to HTTP-streaming in
   conventional Internet.




Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
