              Network File System (NFS) Version 4 Protocol

Abstract

   The Network File System (NFS) version 4 protocol is a distributed
   file system protocol that builds on the heritage of 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 has
   been added.  Of course, attention has been applied to making NFS
   version 4 operate well in an Internet environment.

   This document, together with the companion External Data
   Representation (XDR) description document, RFC 7531, obsoletes RFC
   3530 as the definition of the NFS version 4 protocol.
