Folks,

two questions, the first because I've be taling it for granted, the 
second brought up bu two indenpendent people I talked about DetNet with.

- is a design criteria that the existing MPLS control plane protocols
   shall be able to use with the DetNet dataplane?

- I've heard the opinion (from two different directions) that doing
   replication/elimination other than at the egress/ingress will make the
   solution to complicated. Do we have a good motiation why we need it?

/Loa
