Challenge 2: Dynamic Range of Requirements
Congestion control principles (V. Jacobson) assumptions:
rather static scenario
implicitly target at configurations where BDP of order O(10) packet

Today, much larger BDP and increased dynamics challenge them more and more
=> situations where today's congestion control algorithms react in a suboptimal way
=> low resource utilization, non-optimal congestion avoidance, or unfairness
