An Example [Keshav97]
Assume a WFQ scheduler with all weights 1.0 using three queues (connections)
Packets of size 1, 2, and 2 units arrive at time 0 on connections A, B, and C. A second packet on connection A arrives at time 4.
The link rate is 1.0 unit/s
Initialize the system with R(t)=0, and per-connection finish numbers as zero
