The Trivial File Transfer Protocol (TFTP) is a simple, lock-step file transfer protocol built on UDP. Defined in RFC 1350, it was designed to be lightweight and easy to implement, requiring minimal memory and code footprint. Unlike FTP, TFTP does not provide authentication, directory listing, or encryption.
| Option | Effect |
|--------|--------|
| blksize | Increase block size (e.g., 1468 bytes for Ethernet MTU). |
| timeout | Adjust retransmission timer. |
| tsize | Transfer file size in advance (useful for progress bars). | TFTP Server

In summary, TFTP servers are a straightforward and efficient file transfer solution that has stood the test of time. While they may not be the best choice for all applications, they still have a place in modern networking, particularly in scenarios where simplicity and speed are essential.
