5.5.2 FTP/TFTP Upgrade 5.5.2.1 Introduction to FTP/TFTP
FTP (File Transfer Protocol) / TFTP (Trivial File Transfer Protocol) are both file transfer
protocols that belonging to layer four (application layer) of the TCP/IP protocol stack, used for
transferring files between hosts and between 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
