Technical Summary
 
This memo defines an extension to the Network News Transport Protocol
to provide asynchronous (otherwise known as "streaming") transfer of
articles.  This allows servers to transfer articles to other servers
with much greater efficiency.

RFC 2980 summarizes some ad-hoc transport extensions currently used in
the NNTP protocol.  This document updates and formalizes the CHECK and
TAKETHIS commands and deprecates the MODE STREAM command.

Working Group Summary

The NNTPEXT WG achieved consensus on this document.

Protocol Quality

Scott Hollenbeck reviewed this specification for the IESG.

This protocol was previously described in RFC 2980 in a less formal
form.  Using the deprecated MODE STREAM negotiation command rather than
the new CAPABILITIES command, it is widely implemented in existing NNTP
software, including specifically INN, Diablo, and Cyclone, and those
implementations are known to interoperate.
