      cgl.narada.topology.viewer.Simulation

All Implemented Interfaces:

Runnable

public class Simulation
extends Thread

This class helps simulating the actual system where node addresses would come from some port.

Nested Class Summary

Nested classes/interfaces inherited from class java.lang.Thread

Field Summary

boolean	addOrDelete
List	nodeArray
Random	numberGenerator1
Random	numberGenerator2
static String	ssl
static String	tcp
static String	udp

Fields inherited from class java.lang.Thread

MAX_PRIORITY, MIN_PRIORITY, NORM_PRIORITY

Constructor Summary

Simulation(NodeManagement nm, Screen sc)
Only constructor that makes use of common NodeManagement and Screen objects (by TopologyViewer)

Method Summary

void	addLink() Randomly selects nodes (some logic is applied so that nodes in same super-super cluster are selected, to show high clustering) and insert a single link of one of the available types
void	addNode() Generates a random node address and invokes NodeManagement's method to add the nodes.
void	deleteLink() Deletes a existing link, for simplicity in this simulation all the existing links between pair are deleted.
void	deleteNode() From the stored local array of nodes, select one of the nodes for deletion and invokes NodeManagement's method.
String	getNode() Gets a node address from existing node array.
void	manageLinks() Depending upon the random number, either adds a link or deletes a link in the system.
void	manageNodes() Depending upon the random number, either adds a node or deletes a node in the system.
void	run() Overrides run() of the Thread class.

Constructor Detail

Simulation

public Simulation(NodeManagement nm,
                  Screen sc)

Only constructor that makes use of common NodeManagement and Screen objects (by TopologyViewer)

Method Detail

run

public void run()

Overrides run() of the Thread class.

Specified by:

run in interface Runnable

Overrides:

run in class Thread

manageNodes

public void manageNodes()

Depending upon the random number, either adds a node or deletes a node in the system.

manageLinks

public void manageLinks()

Depending upon the random number, either adds a link or deletes a link in the system.

addNode

public void addNode()

Generates a random node address and invokes NodeManagement's method to add the nodes. Also stores the node in local array required for simulation.

deleteNode

public void deleteNode()

From the stored local array of nodes, select one of the nodes for deletion and invokes NodeManagement's method.

addLink

public void addLink()

Randomly selects nodes (some logic is applied so that nodes in same super-super cluster are selected, to show high clustering) and insert a single link of one of the available types

deleteLink

public void deleteLink()

Deletes a existing link, for simplicity in this simulation all the existing links between pair are deleted.

getNode

public String getNode()

Gets a node address from existing node array.
