Not really.
Time = bc/cir so that 12,500/100,000 gives a sampling time of 125msec.
this means the committed rate is 12.5Kb per 125msec which adds up to 100Kb
per second.
burst excess is over the same sampling period defined by the ration of cir
and bc which is 1/8th second or 125msec so it's not 28Kb per second you've
defined but 28Kb per 125msec or 204Kb per second :)
The correct value for 'be' per 125msec to get 28Kbps is 3500
