The Trivial File Transfer Protocol (TFTP) is a simple, lightweight file transfer protocol commonly used in networking environments for tasks such as booting diskless workstations, transferring configuration files, and—most relevant to our discussion—upgrading firmware on switches, routers, and other network appliances. Unlike FTP or SFTP, TFTP uses UDP (port 69) instead of TCP, which means it doesn't incorporate authentication or encryption. While this sounds like a drawback, the protocol's simplicity and low overhead actually make it ideal for network devices during early boot stages or when a full TCP/IP stack isn't yet available. Because TFTP doesn't require usernames or passwords, the upgrade process becomes almost as simple as copying a file from one folder to another.
