Title : Protocol for Federated Filesystems v1.0
Author(s) : R. Tewari, et al.
Filename : draft-tewari-federated-fs-protocol-01.txt
Pages : 33
Date : 2007-12-03
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 and
collections of
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.

In the body type:
"FILE /internet-drafts/draft-tewari-federated-fs-protocol-01.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
