Description of Working Group:

  Network File System version 4 (NFSv4) is the IETF standard for file

  To maintain NFS Version 4's utility and currency, the NFSv4 working
  group is chartered to maintain the existing NFSv4.0, NFSv4.1, and
  NFSv4.2 protocols and specifications of related ONC components, such as
  those defining RPC, XDR, and RPCSECGSS.

  In addition, extensions will be developed, as necessary, to correct
  problems with the protocols as currently specified, to accommodate
  needed file system semantics, and to respond to technological
  developments in the areas of networking and persistent storage/memory.


  The working group's experience has been that, as NFSv4 implementations
  mature and deployments continue, clarifications and corrections to
  existing RFCs are needed.

  These specification updates help vendors in delivering high-quality and
  interoperable implementations.

  The NFSv4 working group is chartered with vetting reported issues and
  determining correctness of submitted errata.

  In addition, some areas may need more concentrated work to correct the
  specifications already published, to deal with unanticipated
  interactions between features, or to respond to evolving expectations
  with regard to areas such as security. Since necessary changes in such
  cases are generally not appropriate for the errata system, the working
  group will assist in publication of new RFCs that provide implementation
  guidance, editorial modification or technical updates to existing RFCs.

  Since the new NFSv4 versioning framework has been approved, these
  technical updates to NFSv4 minor versions could include limited XDR


  The NFSv4 protocol is designed to allow extension by the definition of
  new operations, new attributes, and new Parallel NFS layout types, as
  well as the creation of minor versions.

  Similarly, associated ONC protocol components that have a versioning/
  extension framework can be incrementally extended, when necessary.

  The working group will discuss proposals for such extensions and assure
  that they have adequate technical review, including discussion of their
  interaction with existing features, before adopting them as working
  group items and helping to draft specification documents.

  Some likely motivations for such extensions would be to:

  Maximize NFS performance on advanced network fabrics.

  Accommodate new storage technologies.

  Provide facilities useful in management of NFS-accessed storage in
  large-scale virtualization environments.

  Provide more effective NFS response to security challenges.

  New milestones that fall within the scope specified in this charter can
  be added to the list below after working group consensus and upon
  approval by the responsible Area Director.
