Abstract

To address the requirement for an NFS protocol that can evolve as the need arises, the Network File System (NFS) version 4 (NFSv4) protocol provides a framework to allow for future changes via the creation of new protocol versions, including minor versions and certain forms of modification of existing minor versions. The extension rules contained in this document allow extensions and other changes to be implemented in a way that maintains compatibility with existing clients and servers.

              Rules for NFSv4 Extensions and Minor Versions

Abstract

   This document describes the rules relating to the extension of the    NFSv4 family of protocols.  It covers the creation of minor versions,    the addition of optional features to existing minor versions, and the    correction of flaws in features already published as Proposed    Standards.  The rules relating to the construction of minor versions    and the interaction of minor version implementations that appear in    this document supersede the minor versioning rules in RFC 5661 and    other RFCs defining minor versions.
