What does that mean? assume that ur normal rate is 512000 bps & ur token bucket is empty without using ur bw 0.5 sec later ur token bucket will be 256000 & after 1sec token bucket will be full (512 Kbps) after that ur exceed bucket starts to fill with 512000 bps or 64000 Bps if u use bw during this time u should subtract using bw per secound from ur cir (in this case 512000) ...

If there is more than 96KB to be transferred in a particular Tc, there comes excess burst in to action. In other words, if there is no enough tokens available in the token bucket during a particular Tc, tokens will be borrowed from excess burst bits. Doesn't it mean that the maximum tokens that can be borrowed in a particular Tc is equal to the size of excess burst? That is, 192KB in above example. If that's true, then the effective maximum allowed traffic rate becomes 1Mbps; Am I not correct? do 2sec u can have 1Mbps after that the excees token bucket will finish & rate decreas to 512 Kbps excess token fill again after overload of conform token ...
