	Title		: A Link-Type sub-TLV to convey the number of 
                          Traffic Engineering Label Switch Paths 
                          signalled signalled with zero reserved bandwidth across a link

Several Link-type sub-TLVs have been defined for OSPF and ISIS in the
   context of Multiprotocol Label Switching (MPLS) Traffic Engineering
   (TE) in order to advertise some link characteristics such as the
   available bandwidth, traffic engineering metric, administrative group
   and so on.  By making statistical assumption on the aggregated
   traffic carried onto a set of TE Label Switched Paths (LSPs)
   signalled with zero bandwdith (referred to as unconstrained TE LSP in
   this document), and with the knowledge of the number of unconstrained
   TE LSPs signalled across a link, algorithms can be designed to load
   balance (existing or newly configured) unconstrained TE LSP across a
   set of equal cost paths.  This requires the knowledge of the number
   of unconstrained TE LSPs signalled across a link.  This document
   specifies a new Link-type Traffic Engineering sub-TLV used to
   advertise the number of unconstrained TE LSP(s) signalled across a
   link.

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
