The IESG has approved the Internet-Draft 'NFS version 4 Protocol' <draft-ietf-nfsv4-rfc3010bis-04.txt> as a Proposed Standard. This document is the product of the Network File System Version 4 Working Group. The IESG contact persons are Allison Mankin and Scott Bradner. Technical Summary This document replaces RFC3010 as the definition of the NFS version 4 protocol. NFS version 4 is a distributed filesystem protocol which owes heritage to NFS protocol versions 2 (RFC1094) and 3 (RFC1813). 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 have been added. Of course, attention has been applied to making NFS version 4 operate well in an Internet environment. Working Group Summary The working group supported publication of this document. Protocol Quality This document was reviewed for the IESG by Scott Bradner.
