Class MinRTTProximityProvider<Identifier>

java.lang.Object
  org.mpisws.p2p.transport.proximity.MinRTTProximityProvider<Identifier>

All Implemented Interfaces:

PingListener<Identifier>, ProximityProvider<Identifier>

public class MinRTTProximityProvider<Identifier>
extends java.lang.Object
implements ProximityProvider<Identifier>, PingListener<Identifier>

Nested Class Summary

class

MinRTTProximityProvider.EntityManager Internal class which is charges with managing the remote connection via a specific route

Field Summary

int	PROX_TIMEOUT millis for the timeout The idea is that we don't want this parameter to change too fast, so this is the timeout for it to increase, you could set this to infinity, but that may be bad because it doesn't account for intermediate link failures
