	Trivial File Transfer Protocol - Wikipedia, the free encyclopedia
		Trivial File Transfer Protocol (TFTP) is a very simple file transfer protocol, with the functionality of a very basic form of FTP; it was first defined in 1980.
		TFTP was therefore useful for booting computers such as routers which did not have any mass storage devices.
		TFTP is based in part on the earlier protocol EFTP, which was part of the PUP protocol suite.

	The TFTP Protocol (Site not responding. Last check: 2007-08-20)
		TFTP is a simple protocol to transfer files, and therefore was named the Trivial File Transfer Protocol or TFTP.
		A transfer is established by sending a request (WRQ to write onto a foreign file system, or RRQ to read from it), and receiving a positive reply, an acknowledgment packet for write, or the first data packet for read.
		Octet mode is used to transfer a file that is in the 8-bit format of the machine from which the file is being transferred.

	RFC 783 (rfc783) - TFTP Protocol (revision 2) (Site not responding. Last check: 2007-08-20)
		Purpose TFTP is a simple protocol to transfer files, and therefore was named the Trivial File Transfer Protocol or TFTP.
		The transfer identifiers (TID's) 5 used by TFTP are passed to the Datagram layer to be used as ports; therefore they must be between 0 and 65,535.
		Initial Connection Protocol A transfer is established by sending a request (WRQ to write onto a foreign file system, or RRQ to read from it), and receiving a positive reply, an acknowledgment packet for write, or the first data packet for read.

	TFTP: Trivial File Transfer Protocol Overview (RFC 1350)
		Three modes of transfer are currently supported by TFPT: netascii, that it is 8 bit ascii; octet (This replaces the "binary" mode of previous versions of this document.) raw 8 bit bytes; mail, netascii characters sent to a user rather than a file.
		The format of the file data that the protocol is to transfer.
		TFTP is defined by IETF (www.ietf.org) in RFC 1350.

		Trivial File Transfer Protocol (TFTP) is a very simple file transfer protocol akin to a basic version of FTP.
		TFTP is often used to transfer small files between hosts on a network, such as when a remote X Window System terminal or any other thin client boots from a network host or server.
		Supports three different transfer modes, "netascii", "octet" and "mail", with the first two corresponding to the "ascii" and "image" (binary) modes of the FTP protocol.

	Trivial File Transfer Protocol
		TFTP, the Trivial File Transfer Protocol was designed, as its name implies, to be a very simplistic protocol that encompasses only the basics of transferring files, and does not include many of the features of standard FTP.
		One drawback of TFTP is the fact that it is a relatively slow protocol; however, speed is often not a major issue when bootstrapping a computer.
		TFTP itself was designed to be a very simple way to transfer files between machines, because it was designed to be so very simple the things that is does in terms of maintaining security can be summed up in two words: "almost nothing".

	TFTP Blocksize Option
		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.
		TFTP is used because it is very simple to implement in a small node's limited ROM space.
		If the amount of data to be transfered is an integral multiple of the blocksize, an extra data packet containing no data is sent to end the transfer.

	Trivial File Transfer Protocol (TFTP)
		Trivial File Transfer Protocol is an Internet Standardized protocol defined in RFC 1350 which is used for transferring files in low security networks.
		Trivial File Transfer performs the file transfer process without requesting a user login and thus is less secure than FTP.
		As it is a UDP protocol, it is referred to as an unreliable protocol because it does not verify that the various parts of the file arrived intact.

	Chapter 15. TFTP: Trivial File Transfer Protocol (Site not responding. Last check: 2007-08-20)
		Unlike the File Transfer Protocol (FTP), which we describe in Chapter 27 and which uses TCP, TFTP was designed to use UDP, to make it simple and small.
		If one server process used the well-known port for the duration of the file transfer, it would either have to refuse any further requests that arrived from other clients, or that one server process would have to multiplex file transfers with multiple clients at the same time, on the same port (69).
		TFTP is a simple protocol designed to fit into read-only memory and be used only during the bootstrap process of diskless systems.

	TFTP (Trivial File Transfer Protocol) (Linktionary term) (Site not responding. Last check: 2007-08-20)
		TFTP is an Internet file transfer protocol similar to FTP (File Transfer Protocol), but it is scaled back in functionality so that it requires fewer resources to run.
		TFTP uses the UDP (User Datagram Protocol) rather than TCP (Transmission Control Protocol), which allows TFTP to be used when the reliability features of TCP are not required and may add excessive overhead.
		TFTP is defined in RFC 1350 (The TFTP Protocol, July 1992).

	File transfer protocol
		The File Transfer Protocol (FTP) is a protocol that is able to transfer files between machines with widely different operating systems.
		It is an 8-bit protocol, capable of handling any type of file without further processing such as MIME or UUEncode[?].
		However, FTP has extremely high latency; that is, the time between beginning the request and starting to receive the required data can be quite long, and a sometimes-lengthy login[?] procedure is required.

	tftp(1): IPv4 Trivial File Transfer Protocol ... - Linux man page
		tftp is a client for the IPv4 Trivial file Transfer Protocol, which can be used to transfer files to and from remote machines, including some very minimalistic, usually embedded, systems.
		Note that the TFTP protocol, unlike the FTP protocol, does not maintain connections between transfers; thus, the connect command does not actually create a connection, but merely remembers what host is to be used for transfers.
		Specify the mode for transfers; transfer-mode may be one of ascii (or netascii) or binary (or octet.) The default is ascii.

	O'Reilly Network -- TFTP and Error Correction
		It's trivialness of purpose (to move one file from one computer to another--nothing more, nothing less) makes it something like a 1950's truck engine: crack open the hood and it's still simple enough to understand in an afternoon.
		TFTP uses lockstep acknowledgement as both flow control and a means of error correction.
		TFTP is typically used only in very tight quarters, these days the only time you're likely to run into it is when booting over a network connection.

	Getting it across with File Transfer Protocol
		And of all the file transfer protocols out there (and there are quite a few), FTP is one of the simplest.
		File transfers can also be performed over UDP using a protocol called Trivial File Transfer Protocol (TFTP), which is a sort of simple cousin to FTP.
		TFTP does not use any form of authentication, and by using UDP, is potentially faster than FTP, although it is also less reliable.

	Overview of TCP/IP > Trivial File Transfer Protocol (TFTP) (Site not responding. Last check: 2007-08-20)
		TFTP is the poor cousin of FTP in that it shares only a very small subset of the capabilities of FTP.
		As a result, TFTP is typically used for embedded applications and copying configuration files for router configuration and in situations where space is of concern, and where security is handled in another fashion.
		TFTP is also used in a network computer environment where each machine is booted from a remote server and where TFTP can be easily embedded in the ROMs (Read Only Memory) on network cards.

		Acknowlegements The protocol was originally designed by Noel Chiappa, and was redesigned by him, Bob Baldwin and Dave Clark, with comments from Steve Szymanski.
		Overview of the Protocol Any transfer begins with a request to read or write a file, which also serves to request a connection.
		Relation to other Protocols As mentioned TFTP is designed to be implemented on top of the Datagram protocol (UDP).

	Understanding the TFTP Protocol
		TFTP is also quite quick, but more on the speed of TFTP a little later on.
		Typical usage of the TFTP protocol is for the storage and retrieval of Cisco IOS and Catalyst switch configuration files.
		Following that, in brackets, is the file that is being requested from the TFTP server located at 192.168.1.101, on its port 69.

	Yet more (Trivial) FTPing
		TFTP is a simplified version of FTP, but the architecture is different enough that regular FTP clients won't be able to talk to a TFTP server - they'll need a TFTP client.
		The standard packet size for TFTP transfers is 512 bytes of data, and on receipt of a smaller packet, the client or server assumes end-of-file has been reached.
		This server supports transfer block sizes up to 8,192 bytes and as small as 8 bytes (the client must be capable of handling what are called "option negotiations" as defined in RFC 1782) and can be configured to not bother sending acknowledgment packets to improve performance.
