Field Details

NULL

static final NetworkTopology NULL

An attribute that implements the Null Object Design Pattern for NetworkTopology objects.

Method Details

addLink

void addLink(SimEntity src,
 SimEntity dest,
 double bw,
 double lat)

Adds a new link in the network topology. The SimEntitys that represent the source and destination of the link will be mapped to BRITE entities.

Parameters:

src - SimEntity that represents the link's source node

dest - SimEntity that represents the link's destination node

bw - link's bandwidth (in Megabits/s)

lat - link's latency (in seconds)

removeLink

void removeLink(SimEntity src,
 SimEntity dest)

getDelay

double getDelay(SimEntity src,
 SimEntity dest)

Calculates the delay (in seconds) between two nodes.

Parameters:

src - SimEntity that represents the link's source node

dest - SimEntity that represents the link's destination node

Returns:

communication delay (in seconds) between the two nodes
