Reno v Vegas demo

Then add SFQ below HTB:

I finally got this to work, after the break. With SFQ, which is a reasonable approximation of Fair Queuing, the Reno and Vegas connections each have their own queues, and these queues do not compete. So Vegas' approach of keeping only a minimal number of packets in the queue does not cost it anything. With a shared queue, the queue-competition rule means that whoever has fewer packets in the queue has correspondingly less bandwidth.

That's why Reno and Vegas came out about even. With a shared queue, Reno beat Vegas by about 8 to 1.

What is BGP about? How does modern routing work?
