BE traffic as it is thought today, should not need an e2e negotiation to
work correctly. However it could be subject to a peer negotiation
(adjacent providers).
But, as we are trying to introduce the notion of e2e services with
performance guarantees, will BE survive in the future ? Or, how long will
it survive ? Or, how much of BE traffic will survive ? (This means, what
applications will keep using BE ?)
Maybe it will appear some levels of better than best effort or lower than
best effor e2e services.
