[[WebNFS]], an extension to Version&nbsp;2 and Version&nbsp;3, allows NFS to integrate more easily into Web-browsers and to enable operation through firewalls. In 2007 Sun Microsystems open-sourced their client-side WebNFS implementation.<ref>{{cite web|url=https://github.com/raisercostin/yanfs|title=yanfs|website=Github.com}}</ref>

Various side-band protocols have become associated with NFS. Note:
* the byte-range advisory Network Lock Manager (NLM) protocol (added to support [[UNIX System V]] [[file locking]] APIs)
* the remote quota-reporting (RQUOTAD) protocol, which allows NFS users to view their data-storage quotas on NFS servers
* NFS over RDMA, an adaptation of NFS that uses [[remote direct memory access]] (RDMA) as a transport<ref>{{cite web|url= http://www.connectathon.org/talks06/talpey-cthon06-nfs-rdma.pdf|title= NFS/RDMA Implementation(s) Update|author= Tom Talpey|publisher= Network Appliance, Inc.|date= February 28, 2006|archive-url= https://web.archive.org/web/20110512180716/http://www.connectathon.org/talks06/talpey-cthon06-nfs-rdma.pdf|archive-date= May 12, 2011}}</ref><ref>{{cite web|url= http://www.usenix.org/events/fast02/wips/callaghan.pdf|title= NFS over RDMA|author= Brent Callaghan|publisher= Sun Microsystems|date= January 28, 2002}}</ref>
