Abstract

   The Network File System (NFS) version 4 is a distributed filesystem
   protocol which owes heritage to NFS protocol version 2, RFC 1094, and
   version 3, RFC 1813.  Unlike earlier versions, the NFS version 4
   protocol supports traditional file access while integrating support
   for file locking and the mount protocol.  In addition, support for
   strong security (and its negotiation), compound operations, client
   caching, and internationalization have been added.  Of course,
   attention has been applied to making NFS version 4 operate well in an
   Internet environment.

   This document replaces RFC 3010 as the definition of the NFS version
   4 protocol.

Key Words
