Network File System version 4 (NFSv4)

NFS Version 4 (RFC 3010, December 2000; revised in RFC 3530, April 2003), influenced by AFS and CIFS, includes performance improvements, mandates strong security, ACLs, locking and introduces a stateful protocol. Version 4 became the first version developed with the Internet Engineering Task Force (IETF) after Sun Micro systems handed over the development of the NFS protocols.
