public class DiffServMonitor

extends java.lang.Object

DiffServMonitor controls the peformance monitoring of each class-type micro-flow of DiffServ packet processing.

Following performance data are provided as the result of monitoring:
	- bandwidth
	- packet delay
	- total byte
	- total packet count
	- packet loss ratio
	- jitter (delay variance)
 
  The DiffServMonitor is turned on by setting the "logfile on" in the   
  ProtocolSession [name DiffServ use gov.nist.antd.diffServ.DiffServTrafficConditioner] 
  of DiffServ-aware LSR.
