RFC 1783:
Title: TFTP Blocksize Option
Author: G. Malkin & A. Harkin
Date: March 1995
Mailbox: gmalkin@xylogics.com, ash@cup.hp.com
Pages: 5
Characters: 7,814
Updates: 1350
URL: ftp://ds.internic.net/rfc/rfc1783.txt
The Trivial File Transfer Protocol (STD 33, RFC 1350) is a simple,
lock-step, file transfer protocol which allows a client to get or put
a file onto a remote host. One of its primary uses is the booting of
diskless nodes on a Local Area Network. TFTP is used because it is
very simple to implement in a small node's limited ROM space.
However, the choice of a 512-byte blocksize is not the most efficient
for use on a LAN whose MTU may 1500 bytes or greater. This document
describes a TFTP option which allows the client and server to
negotiate a blocksize more applicable to the network medium. This RFC
is the product of the TFTP Extensions Working Group of the IETF.
This is now a Proposed Standard Protocol.
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state and
status of this protocol. Distribution of this memo is unlimited.
This announcement is sent to the IETF list and the RFC-DIST list.
