I would like to understand if there is a consensus on securing payload
of MPLS based TDM PW.
One could argue that the PW is emulating a point to point circuit, so
why do we need encryption? but since the data traverses a packet
network, some providers have expressed a need for securing the PW
traffic.

Alternate suggestions are to use IP/UDP encapsulation so that IPSec can
be used. This approach makes us lose the benefits of MPLS traffic
engineering. 

Thoughts or suggestions?


[YJS] I intend presenting in San Diego an approach for accomplishing
this 
(hint: based on MACsec idea).  Also - see draft-stein-pwe3-sec-req.
