Answer: Explanation:
An Internet Draft often denoted with the acronym (I-D) is a six month valid series of document published by the Internet Engineering Task Force . It is a work-in-progress documents not intended for publication by RFC that contains preliminary technical specifications, results of networking-related research, and other technical information. Also, it can eventually be published as a Request for Comments (RFC) which might possibly lead to an Internet Standard. Internet Draft does not have a formal status and this makes it subject to change or removal.
While
A proposed standard is a stable and resolved known design choices that is believed to be well-understood, has received significant community review, and, appears to enjoy enough community interest and this makes it valuable.
Proposed standards are of good quality and its implementations can be deployed in the Internet. However, proposed standards can be updated and improved if problems are noticed or better solutions are found because it should have no known technical omissions in its requirements, although this requirement can be waived by IESG when it is found useful.
Proposed standards deployed on the Internet are broadly used as stable protocols.
