Constructor Details

NetworkDatacenter

public NetworkDatacenter(Simulation simulation,
 List<? extends NetworkHost> hostList,
 VmAllocationPolicy vmAllocationPolicy)

Creates a NetworkDatacenter with the given parameters.

Parameters:

simulation - The CloudSim instance that represents the simulation the Entity belongs to

hostList - list of Hosts that will compound the Datacenter

vmAllocationPolicy - the policy to be used to allocate VMs into hosts

Throws:

IllegalArgumentException - when this Host has zero number of PEs (Processing Elements).

NetworkDatacenter

public NetworkDatacenter(Simulation simulation,
 List<? extends NetworkHost> hostList)

Creates a NetworkDatacenter that uses a VmAllocationPolicySimple as default.

Parameters:

simulation - The CloudSim instance that represents the simulation the Entity belongs to

hostList - list of Hosts that will compound the Datacenter

Throws:

IllegalArgumentException - when this Host has zero number of PEs (Processing Elements).

Method Details

getEdgeSwitch

public List<Switch> getEdgeSwitch()

Gets a map of all Edge Switches in the Datacenter network, where each key is the switch id and each value is the switch itself. One can design similar functions for other type of Datacenter.

Returns:

addSwitch

public void addSwitch(Switch swt)

Adds a Switch to the Datacenter.

Parameters:

swt - the Switch to be added

getSwitchMap

public List<Switch> getSwitchMap()

Gets a read-only list of network Datacenter's Switches.

Returns:

getHostList

public List<NetworkHost> getHostList()

Description copied from interface: Datacenter

Gets an unmodifiable host list.

Specified by:

getHostList in interface Datacenter

Overrides:

getHostList in class DatacenterSimple

Returns:

the host list
