It simplifies the interactionbetween servers and clients remarkably. The TFTP is implemented on the UDP. Ittransfers data through UDP port 69. Basic TFTP operations are described in RFC1986.TFTP transmission is initiated by clients, as described in the following:z To download a file, a client sends a read request to the TFTP server, receives datafrom the TFTP server, and then sends an acknowledgement to the TFTP server.z To upload a file, a client sends a Write request to the TFTP server, sends data tothe TFTP server, and then receives the acknowledgement from the TFTP server.
