ABSTRACT:
The shaping method buffers data packets of the incoming data flow and determines a leaking time moment for a buffered data packet. The leaking time moment is when the buffer should leaks a data packet. Determining the leaking time moment is a function of traffic contract parameters related to the incoming data flow. Status information is received from a marker that is downstream from the shaper, and a conform time moment is determined according to the status information and to a predefined drop priority. When the buffer leaks a data packet at the conform time moment, upon reception, the buffered data packet receives the predefined drop priority from the marker. The conform time moment is compared with the leaking time moment, and when the conform time moment is earlier, the leaking time moment is constituted with the conform time moment to leak the buffered data packet at that time moment.
