The "Trivial File Transfer Protocol" (RFC 1350) is a simple, lockstep,
file transfer protocol that allows a client to get or put a file
onto a remote host.  One of its primary uses is in the early stages of
nodes booting from a Local Area Network (LAN).  TFTP has been used for this
application because it is very simple to implement.  The employment of
a lockstep scheme limits throughput when used on a LAN.

This document describes a TFTP option that allows the client and
server to negotiate a window size of consecutive blocks to send as an
alternative for replacing the single-block lockstep schema.  The TFTP
option mechanism employed is described in "TFTP Option Extension"
(RFC 2347).

This is now a Proposed Standard.
