7-4 LAN Interface Supplement
Using the Network File System (NFS)
Introduction to NFS
NFS Protocols
Current implementations of NFS use transmission control protocol
(TCP) as the transport protocol1 over the network. TCP is a reliable
protocol designed to provide guaranteed data delivery. Your analyzer
uses TCP/IP over the LAN.
NFS also uses remote procedure call (RPC) protocol. RPC is a
client/server protocol providing remote services to a local application
(program). The local application can request and execute a procedure on
a remote machine, pass data to the remote procedure, and retrieve data
from the remote procedure. RPC is a key component of the NFS.
1. The transport protocol governs how data is transmitted over a net-
work.
