Introduction to TFTP
Trivial file transfer protocol (TFTP) is a simple protocol. Compared with FTP, TFTP does
not provide complex interactive access interface and authentication control, and is
suitable for the environments that do not need complex interaction. Generally, TFTP is
implemented based on UDP.
The TFTP file transfer is initiated by a client:
■ When a file needs to be downloaded, the client sends a read request to the TFTP
server. It then receives data from the server and sends acknowledgement to the
server.
■ When a file needs to be uploaded, the client sends a write request to the TFTP
server. It then sends data to the server and receives acknowledgement from the
server.
TFTP can transfer files in two formats:
■ Binary: used to transfer programs.
■ ASCII code: used to transfer text files.
Before configuring TFTP, the network administrator should first configure the IP
addresses of the TFTP client and server and ensure that the client and the server are
reachable to each other.
