RFC3985/6.5. Congestion Considerations
may have some useful text.
We have a lot of deployment experience with
PWs and frankly I have never seen a congestion
complain raised from the field.

Hi Lars,
Thanks a lot for your comments.
I wonder whether the following modified text for Congestion Consideration
section is OK from your point of view:
Since the MPLS-in-UDP encapsulation causes MPLS packets to be forwarded
through "UDP tunnels", the congestion control guidelines for UDP tunnels as
defined in Section 3.1.3 of [RFC5405] SHOULD be followed. Specifically, MPLS
can carry a number of different protocols as payloads. When the payload
traffic is IP-based and congestion-controlled, the UDP tunnel SHOULD NOT
employ its own congestion control mechanism, because congestion losses of
tunneled traffic will already trigger an appropriate congestion response at
the original senders of the tunneled traffic. When the payload traffic is not
known to be IP-based, or is known to be IP-based but not
congestion-controlled, the UDP tunnel SHOULD employ an appropriate congestion
control mechanism. Furthermore, because UDP tunnels are usually bulk-transfer
applications as far as the intermediate routers are concerned, the guidelines
as defined in Section 3.1.1 of [RFC5405] SHOULD apply.
Best regards,
Xiaohu

this document needs to describe how it addresses the issues raised in BCP145
(RFC5405). It already contains some text about messages sizes and congestion
considerations, which is great. Unfortunately, the text about congestion
considerations is not fully in line with RFC5405.
