File Transfer Protocol (FTP)
The SNAP driver also is responsible for distributing incoming packets to the IP and
ARP software. Incoming packets are delivered to the SNAP driver from SLSA in the
form of AGSDUs. The SNAP driver separates the individual messages and strips off
unnecessary protocol headers before delivering messages to the IP and ARP input
routines.
For more information on the SNAP, refer to RFC 1042 (available on the Internet at:
http://ds.internic.net/ds/rfc-index.html.)
File Transfer Protocol (FTP)
The File Transfer Protocol facilitates the transfer of files between hosts. For information
about FTP, see the TCP/IP Applications and Utilities User Guide.
Trivial File Transfer Protocol (TFTP)
The Trivial File Transfer Protocol client and server programs run over a UDP socket.
For information about TFTP, see the TCP/IP Applications and Utilities User Guide.
