peersim.transport
Class E2ENetwork

java.lang.Object
  peersim.transport.E2ENetwork

public class E2ENetwork
extends java.lang.Object

This static singleton emulates an underlying router network of fixed size, and stores the latency measurements for all pairs of routers.

Method Summary

static int	getLatency(int sender, int receiver) Returns the latency associated to the specified (sender, receiver) pair.
static int	getSize() Returns the current size of the underlying network (i.e., the number of routers).
static void	reset(int size, boolean symm) Resets the network, by creating a triangular (if symm is true) or a rectangular (if symm is false) array of integers.
static void	setLatency(int sender, int receiver, int latency) Sets the latency associated to the specified (sender, receiver) pair.

Method Detail

reset

public static void reset(int size,
                         boolean symm)

Resets the network, by creating a triangular (if symm is true) or a rectangular (if symm is false) array of integers. Initially all latencies between any pairs are set to be 0.

Parameters:

size - the number or routers

symm - if latency is symmetric between all pairs of routers

getLatency

public static int getLatency(int sender,
                             int receiver)

Returns the latency associated to the specified (sender, receiver) pair. Routers are indexed from 0.

Parameters:

sender - the index of the sender

receiver - the index of the receiver

Returns:

the latency associated to the specified (sender, receiver) pair.

setLatency

public static void setLatency(int sender,
                              int receiver,
                              int latency)

Sets the latency associated to the specified (sender, receiver) pair. Routers are indexed from 0.

Parameters:

sender - the index of the sender

receiver - the index of the receiver

latency - the latency to be set

getSize

public static int getSize()

Returns the current size of the underlying network (i.e., the number of routers).
