Hi draft-ietf-core-cocoa-01-authors, Hi all,

I have started to read the CoAP congestion control document and I have a
few comments.

One of the most important sections of a document, the introduction
section, is empty. As a reader I would find it useful
* to learn what the perceived problem is, and
* to have enough information to decide whether I want to implement this
specification.

Are there answers to these questions?

I know that there are these other referenced documents that **may**
contain some of that necessary content but do you expect the reader to
read them to understand this document? I think this document has to be
self-contained.

I also believe that many readers are worried that the enhancements to
CoAP over UDP quickly turn into CoAP over TCP. Are there suggestions on
when a deployment should switch to CoAP over TCP rather than using CoAP
over UDP with this advanced congestion control algorithm?

Ciao
Hannes
