What I am trying to create here is a typical network provider scenario
where the core of the network has limited resources (10Mbit) and has to
manage traffic from the clients which might aggregate to be more than the
core's capacity (100Mbit). Since network providers use statical
multiplexing, they usually sell more bandwidth than is actually present in
the network.
This is where QoS steps in which is what we are researching. Hope this
clarifies the requirement.
