I-D ACTION:draft-ietf-pce-disco-proto-isis-08.txt

A New Internet-Draft is available from the on-line Internet-Drafts 
directories.
This draft is a work item of the Path Computation Element Working Group of the IETF.

	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-08.txt

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 Elements (PCEs), 
   along with information that can be used by the PCC for PCE selection. 
   When the PCE is a Label Switching Router (LSR) participating in the 
   Interior Gateway Protocol (IGP), or even a server participating 
   passively in the IGP, a simple and efficient way to announce PCEs 
   consists of using IGP flooding. For that purpose this document 
   defines extensions to the Intermediate System to Intermediate System 
   (IS-IS) routing protocol for the advertisement of PCE Discovery 
   information within an IS-IS area or within the entire IS-IS routing 
   domain.

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
