Class SpeedManagerAlgorithmProviderDHTPing

java.lang.Object
  com.aelitis.azureus.core.speedmanager.impl.v2.SpeedManagerAlgorithmProviderDHTPing

All Implemented Interfaces:

SpeedManagerAlgorithmProvider, COConfigurationListener

public class SpeedManagerAlgorithmProviderDHTPing
extends java.lang.Object
implements SpeedManagerAlgorithmProvider, COConfigurationListener

This class implements an Vivaldi strategy for adjusting the upload limit. It will every 30 seconds calculate the distance to the center of the Vivaldi structure and if it determines that it is going away from it will lower the limit. If it getting closer it will increase the upload limit.
