Ouvrage 9780201325706 : NFS ILLUSTRATED
The Network File System (NFS) protocol that
enables remote access to files is now a key element
of any LAN. As well, it is currently and increasingly used as a key technology with the
Web and wide area networks.
Written for programmers creating NFS-based applications, network engineers creating new
implementations of NFS, and network managers, NFS Illustrated promotes a thorough
understanding of that protocol, animating it through extensive diagrams and real protocol
traces that show NFS in action. Covering NFS versions 2 and 3, the book also looks into
WebNFS and the new NFS version 4, with Internet support. Detailed and authoritative, the
book not only examines NFS in depth, but also describes the protocols that underlie and
support it, including External Data Representation (XDR), Remote Procedure Call (RPC),
the NFS MOUNT protocol, and the NFS Lock Manager protocol. It discusses several NFS
variants and compares NFS to a number of alternative file systems.
You will find a detailed discussion on the NFS filesystem model and a
procedure-by-procedure description of NFS versions 2 and 3, illustrated through the use of
snoop traces that capture and display protocol packets from the network. In addition, the
book addresses real-world implementation issues faced by those building an NFS client or
server, factors that affect NFS performance, and critical performance benchmarks.
Specific topics of interest include:
* NFS version 4, highlighting performance improvements, security features, and
cross-platform interoperability for Internet operation * RPC authentication and security *
Differences between NFS versions 2 and 3 * Implementation issues for clients and servers
* Read-ahead and write-behind * Caching policies * The Lock Manager protocol *
Automounting * NFS variants, including Spritely NFS, NQNFS, Trusted NFS, and NASD
NFS * NFS competitors: RFS, AFS, DCE/DFS, and CIFS * The PCNFS protocol for
implementing NFS on PC operating systems * SPEC SFS benchmarks, WebNFS, and
firewalls
Comprehensive and current, NFS Illustrated is an essential resource for network
professionals who want to use this widespread and evolving technology to its fullest.
About the Author
Brent Callaghan is a thirteen-year veteran of the Sun Microsystems NFS group. After
completing the first automounter, he helped design NFS version 3, wrote the snoop
network analysis program, and was the architect for WebNFS. He is currently working on
NFS version 4 and is the co-chair of the IETF working group.
