Editing Trivial File Transfer Protocol (section)

==Overview==
Due to its 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 [[Bootstrap Protocol|BOOTP]], [[Preboot Execution Environment|PXE]], [[Boot Service Discovery Protocol|BSDP]], etc.,  when targeting from highly resourced computers to very low resourced [[Single-board computer]]s (SBC) and [[System-on-a-chip|System on a Chip]] (SoC). It is also used to transfer [[firmware]] images and configuration files to network appliances like [[Router (computing)|routers]], [[Firewall (computing)|firewalls]], [[IP phone]]s, etc. Today, TFTP is virtually unused for Internet transfers.

TFTP's design was influenced from the earlier protocol [[EFTP]], which was part of the [[PARC Universal Packet protocol suite]]. TFTP was first defined in 1980 by [[Internet Experiment Note|IEN]] 133.<ref>{{cite IETF

In June 1981 The TFTP Protocol (Revision 2) was published as RFC 783 and later updated 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 updated later in May 1998 by RFC 2347, defined the option negotiation mechanism which establishes the framework for file transfer options to be negotiated prior to the transfer using a mechanism that is consistent with TFTP's original specification.

TFTP is a simple protocol for transferring files, implemented on top of the [[UDP/IP]] protocols using [[well-known port]] number 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 protocols. TFTP only reads and writes 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]]s (LAN).
