Upgrading Applications Using FTP
When application files are large, you can also upgrade them using the File Transfer Protocol (FTP) to
greatly shorten the upgrade and maintenance time.
As an application layer protocol in the TCP/IP suite, FTP is mainly used for file transfer between
remote hosts. FTP provides reliable and connection-oriented data transfer services over TCP. FTP
does not provide any access authorization or authentication mechanism. The FTP program file is
much larger than the TFTP program file.
