public class PortStatsRates
extends PortStats

Augments PortStats by keeping track of the rates of packets, bits, and flows.

Method Summary

double	getBitsPerSec() Gets the number of bits per second for these stats
double	getFlowsPerSec() Gets the number of flows per second for these stats
double	getPacketsPerSec() Gets the number of packets per second for these stats

Method Detail

getPacketsPerSec

public double getPacketsPerSec()

Gets the number of packets per second for these stats

getBitsPerSec

public double getBitsPerSec()

Gets the number of bits per second for these stats

getFlowsPerSec

public double getFlowsPerSec()

getWeightOfNew

public double getWeightOfNew()

Gets how strongly new rates are weighted over the previous weight

setWeightOfNew

public void setWeightOfNew(double w)

Sets how strongly new rates are weighted over the previous weight.

Parameters:

w - will be clamped to the range of 0.0 to 1.0 inclusive

setRates

public void setRates(double packetsPerSec,
