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.
