This document provides advice to the designers of digital
communication equipment and link-layer protocols employing
link-layer Automatic Repeat reQuest (ARQ) techniques.  This document
presumes that the designers wish to support Internet protocols, but
may be unfamiliar with the architecture of the Internet and with the
implications of their design choices for the performance and
efficiency of Internet traffic carried over their links.

ARQ is described in a general way that includes its use over a wide
range of underlying physical media, including cellular wireless,
wireless LANs, RF links, and other types of channel.  This document
also describes issues relevant to supporting IP traffic over
physical-layer channels where performance varies, and where link ARQ
is likely to be used.

This document is a product of the Performance Implications of Link
Characteristics Working Group of the IETF.

This document specifies an Internet Best Current Practices for the
Internet Community, and requests discussion and suggestions for
improvements.  Distribution of this memo is unlimited.
