Hi All, Was going over some more QoS today. In MQC, when we do policing, it seems like the math "adds up" so to speak. Fx. if i police to 64000bps, Bc goes to 2000 (bytes), and with Tc set for 250ms, this adds up. However, when using CAR, Cisco recommends: rate (in bytes) * 1,5 for the Burst value. This seems very odd to me, to say the least. First off, I thought of Burst of as Bc, in which case Bc is in each Tc, but then the number got all screwed up. It would seem to me that when using CAR, Burst is not related to Bc in any way. And the 1,5 is just to factor in any inconsistencies.
It would also appear, that when _not_ using CAR, such as policing in MQC, that the recommendation for 1,5 does not apply? Any clarification or comments?
