Hmm...so if i understand this correctly, 'burst' controls 'rate' and 
'cburst' controls 'ceil'?

Lets say that i am generating bursty fixed length UDP traffic i.e.1470 
bytes every 5000us.
Now for a pkt size of 1470 bytes and 'rate' and 'ceil' being 1.536Mbit 
what would be the ideal values of burst and cburst?
