'''EFTP''' is a very simple, basic [[file]] transfer [[protocol]], a [[data network]] [[application]] (the name notwithstanding) used to transfer files to or from a [[server]] [[host]] system, in the [[PARC Universal Packet|PUP]] [[protocol suite]].

Unlike many current protocols, it is not run over a [[reliable byte stream]] protocol; instead, it is built directly on the un-reliable [[datagram]] service provided by PUP. EFTP includes its own [[acknowledgement]]s, [[timeout]]s, and [[re-transmission]]s, and uses the [[checksum]]s and [[sequence number]]s provided by the underlying PUP layer.

This approach is a result of its creation in the very early stage of data networking work, when many computers were simpler, and reliable byte stream protocol were often not available in them; EFTP provides file transfer functionality from a small amount of code, suitable for uses such as [[bootstrap]]ping a machine with no [[secondary storage]] over the network.
