The Network File System (NFS) is the major
alternative to the Open Software Foundation. With
more than one million NFS computers already in
existence, it is time for an authoritative volume that
explains what NFS does and how it is used.
Analyzing Sun Networks presents a thorough
overview of major industry standard protocols and
architectures in the Network File System and TCP/IP
environments. In addition to information for SUN
workstation vendors and users the material applies
to any vendor that has TCP/IP support—IBM, DEC,
Sun, AT&T, Hewlett Packard, Novell, Cray, and many
others.
This is the first book to describe NFS and the related
protocols in the Open Network Computing ONC
family. It covers the NFS, Remote Procedure Calls,
License Servers, the Automounter, and a wide
variety of other services in the ONC and Internet
protocol families. There is also extensive discussion
of TCP/IP and the underlying network on which
TCP/IP is built. Numerous case studies of
Supercomputer sites, and Sun's own internal leading-
edge network users give the discussion a real-world
flavor. Throughout the book, extensive examples of
actual network traffic are shown.
Also featured are chapters on many other topics that
are critical in developing and implementing today's
computer networks:
® |nteroperability with OSI
= Messaging and X.400
= Naming services
= Security and public key encription
= Network management and SNMP
= The Network Time Protocol
