GPS example
connection ?i {(aik, Lik)}
1 0.5 {(0,1), (0,1), (0,1), ...}
2 0.1 {(0,1), (0,1), (0,1), ...}
3 0.1 {(0,1), (0,1), (0,1), ...}
6 0.1 {(0,1), (0,1), (0,1), ...}
- a packet may complete quite a bit earlier in WFQ than in GPS
- connection 1 gets very bursty service
- a packet of connection 1 may be kept waiting a long time even though its queue is empty
- Worst-case Fair WFQ (WF2Q) -- to address these problems
