Hi Melvin,

Thanks for both of your emails on this subject.

It is the intention of draft-yasukawa-mpls-p2mp-requirement-01.txt to make sure that any
p2mp solution developed in the MPLS WG should be applicable to other switching types (i.e.
non-packet).

Scalability is, of course, a significant concern.
draft-yasukawa-mpls-p2mp-requirement-01.txt describes networks where the branch points are
within the network and not at the edges. Scaling issues are mentioned at many points in
the draft.

There are currently two proposed solutions drafts (it is to be hoped that these may
converge on a single solution over time). Both proposed solutions take some pains to
ensure optimal use of network resources. Both solutions currently have some scaling issues
within the control plane, but I'm sure the authors are working to resolve these issues.

Cheers,
Adrian
