first parameter (2 Mbps): average rate - long term average transmission rate
2nd parameter (512 Kbps): normal burst size - determines how large traffic bursts can 
be before SOME traffic exceeds the rate limit
3rd parameter (786 Kbps): excess burst size - determines how large traffic burst can 
be before ALL traffic exceeds the rate limit
