Introduction to FTP Client
As an additional function provided by Ethernet switch, FTP client is an application
module and has no configuration functions. The switch connects the FTP clients
and the remote server and inputs the command from the clients for corresponding
operations (such as creating or deleting a directory).
Trivial File Transfer Protocol (TFTP) is a simple protocol for file transmission.
Compared with FTP, another file transmission protocol, TFTP has no complicated
interactive access interface or authentication control, and therefore it can be used
when there is no complicated interaction between the clients and server. TFTP is
implemented on the basis of UDP.
TFTP transmission originates from the client end. To download a file, the client
sends a request to the TFTP server and then receives data from it and sends
acknowledgement to it. To upload a file, the client sends a request to the TFTP
server and then transmits data to it and receives the acknowledgement from it.
TFTP transmits files in two modes, binary mode for program files and ASCII mode
for text files.
