                NSDB Protocol for Federated Filesystems
               draft-ietf-nfsv4-federated-fs-protocol-12

Abstract

   This document describes a filesystem federation protocol that enables
   file access and namespace traversal across collections of
   independently administered fileservers.  The protocol specifies a set
   of interfaces by which fileservers with different administrators can
   form a fileserver federation that provides a namespace composed of
   the filesystems physically hosted on and exported by the constituent
   fileservers.
