I'm back with another question regarding how one goes about determining the different thresholds used in a QoS policy. For WFQ how do I determine the CDT and number of dynamic queues to use?? For WRED how do I determine the low and high thresholds and the MPD?? If I were to use tail-drop, how would I defined the queue-limit?? Does it all have to do with the speed of the interface?? Is there a scientific forumla to use to calculate these numbers?? I have a very good grasp of the whole QoS technology, but I just feel like I'm really missing something when it comes to determining these numbers. Thanks ahead of time for your help.
