Namespace Database (NSDB) Protocol for Federated File Systems
Abstract
This document describes a file system 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 file systems physically hosted on and exported by the constituent
fileservers.
