Title : IS-IS protocol extensions for Path Computation Element (PCE) Discovery
Author(s) : J. Le Roux, et al.
Filename : draft-ietf-pce-disco-proto-isis-01.txt
Pages : 22

There are various circumstances where it is highly desirable for a
Path Computation Client (PCC) to be able to dynamically and
automatically discover a set of Path Computation Element(s) (PCE),
along with some of information that can be used for PCE selection.
When the PCE is a Label Switch Router (LSR) participating to the IGP,
or even a server participating passively to the IGP, a simple and
efficient way for PCE discovery consists of relying on IGP flooding.
For that purpose this document defines IS-IS extensions for the
advertisement of PCE Discovery information within an IS-IS area or
within the entire IS-IS routing domain.

In the body type:
"FILE /internet-drafts/draft-ietf-pce-disco-proto-isis-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.
