Ballot Text

Technical Summary

This document defines a mechanism to prevent the maximum size of the
label space limit on an LSR from being a constraint to control plane
scaling on that node.  It introduces the notion of pre-installed 'per
Traffic Engineering (TE) link labels' that can be shared by MPLS
RSVP-TE LSPs that traverse these TE links.  This approach
significantly reduces the forwarding plane state required to support
a large number of LSPs.  This couples the feature benefits of the
RSVP-TE control plane with the simplicity of the Segment Routing MPLS
forwarding plane.

Working Group Summary

No such controversies. The WG process has been very

Document Quality

We know of implementation plans and implementations, this was the
reason to allocate some of the code points by early allocation.
However we have no detailed information. We have started an
implementation poll and will update the Write-Up when we receive
more information.

No expert reviews necessary.
