If the client IP network were to used MPLS signaling to obtain services from
the optical transport network, and if the optical transport network were
clever about enforcing a configurable admission control policy, would there
be any need for a UNI? Couldn't the admission control policy restrict client
networks to services that they might otherwise have obtained through the
UNI?
