Trivial file transfer protocol (TFTP) is a simple lockstep file transfer protocol which allows a client to get a file from 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.
Tftp has been used for this application because it is very simple to implement.
Tftp was first standard zed in 1981 and the current specification for the protocol can be found in rfc 1350.

Due to simple design, tftp can be easily implemented by code with a small memory footprint. It is therefore the protocol of choice for the initial stages of any network booting strategy like bootp, pxe, bsdp, etc. When targeting from highly resorced single board computer (SBC) and system on a chip (SoC). It is also used to transfer firmware images and configuration files to network appliances like routers, firewalls, IP phones, etc.

Today, tftp is virtually unused for internet transfer.

Tftp design was influenced from the earlier protocol eftp, which was part of the pup protocol suite. Tftp was first defined in 1980 by ien 133. In June 1981 the tftp protocol (revision 2) was published as rfc 783 and later up dated in July 1992 by RFC 1350 which fixed among other things the sorcerer's apprentice syndrome. In march 1995 the tftp option extension rfc 1782 update later in may 1998 by rfc 2347, defined the option negotiation mechanism for file transfer options to be negotiated prior to the transfer using a mechanism which is consistent with tftp's original specification.

Tftp is a simple protocol for transferring files, implemented on top of the udp/ip ip protocols using well-known port nu6 69. Tftp was designed to be small and easy to implement, and therefore it lacks most of the advanced features offered by more robust file transfer offered by more robust file transfer protocol.

Tftp only ready and write files from or to a remote server. It cannot list, delete, or rename files or directories and it has no provisions for user authentication.

Today tftp is generally only used on local area network (LAN).

Tetp definnes three modes of transfer: netascii, octet, and mali.

Netascii is a modified from of ascll defined in rfc 764. It consists of an 8-bit extension of the 7-bit ASCII character space from 0x7f (the printable character and the space) and eight of the control character. The allowed control characters include the null (0x00), the line feed (lf, 0x0a), and the carriage return (cr, 0x0d). Netascii also require that the end of line marker on a host be translated to the character pair cr lf for transmission, and that any cr must be followed by either a lf or the null.

Octet allow for the transfer of arbitrary raw 8-bit bytes, with the received file resulting byte-per-byte identical to the one sent. More correctly, if a host receves an octet file must be identical to the original.

Mail transfer mode uses netascii transfer, but the file is sent to an email recipient by specifying that recipient's email address as the file name. Rfc 1350 declared this mode of transfer obsolete.
