Abstract

   The main task of the NFS version 4 working group is to create a
   protocol definition for a distributed file system that focuses on the
   following items: improved access and good performance on the
   Internet, strong security with negotiation built into the protocol,
   better cross-platform interoperability, and designed for protocol
   extensions.  NFS version 4 will owe its general design to the
   previous versions of NFS.  It is expected, however, that many
   features will be quite different in NFS version 4 than previous
   versions to facilitate the goals of the working group and to address
   areas that NFS version 2 and 3 have not.

   This design considerations document is meant to present more detail
   than the working group charter.  Specifically, it presents the areas
   that the working group will investigate and consider while developing
   a protocol specification for NFS version 4.  Based on this
   investigation the working group will decide the features of the new
   protocol based on the cost and benefits within the specific feature
   areas.
