US Patent 7778178 Oversubscribing bandwidth in a communications network

A system and computer readable medium for oversubscribing bandwidth in a communication network, is disclosed. The system and computer readable medium includes policing a first data flow and outputting a first output data flow from the first meter, in relation to a first Committed Information Rate (CIR) and a first Peak Information Rate (PIR); policing a second data flow and outputting a second output data flow from the second meter in relation to a second CIR and a second PIR; and policing an aggregated output data flow of the first output data flow and the second output data through a third meter of the oversubscription module, where the aggregated output data flow is policed in relation to a third CIR and a third PIR.
