Name	Type	Description
FlowMeasurementStarter	simple module	Initiates packet flow measurements by adding time tags to selected packets. Supports measuring various timing aspects including elapsed time, delaying time, queueing time, processing time, transmission time, and propagation time. Can be configured to measure specific packet regions and to filter which packets are measured.
