Upgrading Application
Program Through
Ethernet Interface
TFTP (Trivial File Transfer Protocol) is a protocol of the TCP/IP suite that is used to
transfer trivial files between clients and the server. It provides not-so-complex and
low-cost file transfer services. Carried over UDP, TFTP provides unreliable data
transfer services and does not provide access authorization and authentication
mechanism. It employs timeout retransmission to guarantee the successful
transferring of data. TFTP takes much smaller size than FTP.
As an application layer protocol in the TCP/IP suite, FTP (File Transfer Protocol)
mainly transfers files among remote hosts. Carried over TCP, it provides reliable
and connection-oriented data transfer service but does not provide access
authorization and authentication mechanism.
Step 1: Set up an upgrade environment.
