How is "DiffRouting" different from
old Type-of-Service (ToS) routing?

My answer:
By constructing multiple road systems, which  eventually are even constructed in awareness of
road systems constructed before (e.g. overflow road system X-overflow w.r.t. road system X)
and to lock traffic into some road system so that it is kept out of the way from other traffic. It may mean not to
take the shortest path for the individual micro flow.
