           Administration Protocol for Federated File Systems

Abstract

   This document describes the administration protocol for a federated
   file system (FedFS) 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 file systems physically hosted
   on and exported by the constituent fileservers.
