I don’t have much time to write more about the whole congestion-control thing right now, but if I hear one more person blather about how the next version of DOCSIS will or won’t solve the problem, then I will fly to wherever there and strangle that person with some optical fiber or twisted pair (their choice). A problem that exists within only one last-mile technology is a problem for the service provider alone, and a solution implemented only within one last-mile technology is no solution at all. When you act as though all the world’s a cable modem, you only show that you don’t really understand the problem.
