Abstract:
1. A method of policing a traffic flow comprising: performing a first stage of policing on the traffic flow to produce a first stage conforming flow and a first stage violating flow; policing the first stage violating flow; policing the first stage conforming flow in a manner which allows the first stage conforming flow to take advantage of a capacity allowed for the first stage violating flow which is unused by the first stage violating flow; wherein policing the first stage conforming flow and policing the first stage violating flow comprises: maintaining a credit count for the first stage conforming flow in combination with the first stage violating flow; enforcing a first burst parameter on the first stage conforming flow and enforcing a second burst parameter on the first stage violating flow, the second burst parameter being smaller than the first burst parameter, to produce a second stage conforming flow and a second stage violating flow.
