Several Link-type sub-Type-Length-Values (sub-TLVs) have been defined
for Open Shortest Path First (OSPF) and Intermediate System to
Intermediate System (IS-IS) 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 assumptions about the aggregated traffic carried onto a
set of TE Label Switched Paths (LSPs) signalled with zero bandwidth
(referred to as "unconstrained TE LSP" in this document), algorithms
can be designed to load balance (existing or newly configured)
unconstrained TE LSP across a set of equal cost paths.  This requires
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 LSPs signalled across a link.  [STANDARDS TRACK]
