Hey everyone,
 
I'm really trying to understand all the options for QoS and I'm currently looking at CB Shaping. Why would one want to shape to a _peak_ instead of shaping to an _average_? I understand that shaping to a _peak_ will try to send Bc + Be bits during every Tc, but doesn't that defeat the whole purpose of shaping? Why not just shape to an _average_ but just make the Bc the total combined value of the Bc and Be values used when shaping to a _peak_, and not configure a Be?
 
Am I missing something?
 
TIA,
Ken
