Abstract:
1. A method for controlling conformance of a data flow in a communication system to a traffic definition associated with a specified quality of service, the communication system having a transmitter and a receiver, the method comprising the steps of: providing a data flow consisting of data units of an upper layer in a protocol stack and a traffic definition for said data flow; transporting the data flow by data packets of an underlying layer in the protocol stack sent from the transmitter to the receiver; sending, by the receiver, responses identifying received data packets to the transmitter for the data packets transporting the data flow; the transmitter utilizing a control function of the underlying layer for controlling the number of sent data packets for which no response is received, according to a limit for the number of outstanding data packets; obtaining a predefined conditioning criterion for the data flow, the conditioning criterion being associated with the traffic definition, determining, at the receiver, a conformance parameter for the received data packets transporting the data flow, wherein
