2.5.2 FTP/TFTP Upgrade

2.5.2.1 Introduction to FTP/TFTP
FTP(File Transfer Protocol)/TFTP(Trivial File Transfer Protocol) are both file transfer
protocols that belonging to fourth layer(application layer) of the TCP/IP protocol stack,
used for transferring files between hosts, hosts and switches. Both of them transfer files in
a client-server model. Their differences are listed below.
FTP builds upon TCP to provide reliable connection-oriented data stream transfer
service. However, it does not provide file access authorization and uses simple
authentication mechanism(transfers username and password in plain text for
authentication). When using FTP to transfer files, two connections need to be established
between the client and the server: a management connection and a data connection. A
transfer request should be sent by the FTP client to establish management connection on
port 21 in the server, and negotiate a data connection through the management
connection.
