public class TrafficMonitor2

extends CountMonitor2

This component monitors the incoming traffic and outputs its throughput and packet loss rate. The implementation is moved to CountMonitor2 for general applications. This component remains for backward compatibility.

This component works the same as TrafficMonitor except that it also calculates packet loss rate in the current window, provided that the packets contain correct ordering information. It calculates the loss rate by summing up the "gaps" found between the ordering information in the packets in the current window. The calculation may not be correct if packets may arrive out of order in different windows.

Same as TrafficMonitor, this component is configured by two parameters: the window size (default one second) and the output interval (default 0.5 second). It can operate in the "byte" mode, the "packet" mode, or both. The throughput events are exported at either the bytecount@ port or the pktcount@ port, and the loss rate exported at either the byteloss@ port or the pktloss@ port, both in percentage(%).
