public class SRTCMMeter

extends DiffServMeterMarker

For the measurement of the arrival rate of the DiffServ class-type packets, Token Bucket Meter (TBM) is used with SRTCM (Single Rate Three Color Marker) or TRTCM (Two Rate Three Color Markter).
TBM with SRTCM is usually used for NCT and EF class-type where the packet rate is defined by peak information rate (PIR) with peak burst size (PBS). According to the result of the data rate measurement, each packet is colored to

	  - Green (conforming PIR/PBS and CIR/CBS)
	  - Yellow (conforming PIR/PBS and CIR, but exceeding CBS)
	  - Red (exceeding PIR/PBS)
