The Trivial File Transfer Protocol [1] 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-octet 
blocksize is not the most efficient for use on a LAN whose MTU may 1500 
octets or greater. 
                                                        
This document describes a TFTP option which allows the client and server to
negotiate a blocksize more applicable to the network medium.  The TFTP 
Option Extension mechanism is described in [2].

Send a message to:  [e-mail]. In the body type: 
     "FILE /internet-drafts/draft-malkin-tftpexts-blksize-opt-01.txt".
							
NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.
							
							

Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
of the Internet-Draft.
