A user data protocol is more straightforward than a complicated TCP layer. It is an application layer protocol (client-server) with TFTP client software for its clients and TFTP server software meant for TFTP servers.Ī point to note is that TFTP utilizes the User Data Protocol (UDP) layer to transport data over the network. Like FTP, TFTP also utilizes the same client/server software to connect two PCs. First, let us look at the basic theory of operation and how the TFTP server works.

However, it offers fewer features than FTP, hence whips with a smaller footprint. To say, TFTP is the lightweight and more straightforward file transfer protocol that is somewhat similar to FTP. Then again, making itself a core element of Preboot Execution Environment (PXE) and network boot protocol.

This feature becomes a precise and more organized way to boot PCs that don’t possess any storage drives.

So that you know, a TFTP server needs a minimal amount of storage for its implementation. But that does not limit the sender and receiver to select other transfer ports as they can do this once the connection starts. Principally, the data transfer in the TFTP server initially begins with port 69.
