Abstract:
A method of determining an event-based rate policing window, comprising:receiving a data unit;generating an event time stamp reflecting a time at which said data unit was received;associating said event time stamp with said data unit;generating a rate policing window end time by adding a rate policing window start time to a rate policing window duration;comparing said event time stamp with said rate policing window end time;starting, in the event that said event time stamp indicates a time subsequent to said rate policing window end time, a new rate policing window;wherein said data unit is received on a virtual connection, and wherein said rate policing window start time, said rate policing window end time, said rate policing window duration, and said new rate policing window are associated with said virtual connection; andwherein said rate policing window start time defines a time at which a current rate policing window started, wherein said rate policing window duration defines a length of said current rate policing window, wherein said rate policing window end time defines an end of said current rate policing window, and wherein said current rate policing window defines a time interval during which a predetermined amount of bandwidth is reserved as guaranteed bandwidth for use by data units received on said virtual connection during said current rate policing window.
