QoS LLQ (Low Latency Queueing) on Cisco IOS

Hello Rene,
Couple of questions.

  1. Is it possible to provide me an example to show the difference between congestion management and congestion avoidance. As a matter of fact, I do not understand TCP Global Synchronization very well. It will be great if you use an example to explain congestion management and avoidance by relating to TCP Global Synchronization.

  2. This question is basically based upon Priority command VS Bandwidth command. Priority command is used to ensure the maximum bandwidth during the congestion. On the other hand, Bandwidth is used to ensure minimum bandwidth during congestion as you know. For example, Priority 10 Kb command will ensure the maximum of 10 Kb traffic during the congestion. On the other hand, Bandwidth 10 Kb will ensure minimum 10 Kb traffic during the congestion. Why does it work that way? What is the benefit? Would you please explain it with an example so I can visualize it?

Thank you so much.
