  In networks, the resources of bottlenecks are shared by remote senders.
Besides, the bottlenecks migrate as the distributed load changes. Not
knowing which resources to slice makes it difficult to do the slicing.
Whereas global scheduling of Internet transmission resources is an appealing
idea advocated by a number of (excellent) researchers over a number of
years, there has not been much concrete progress in this direction. Schemes
like XCP come the closest, while still staying in the probing
congestion-control camp.
