Class NetworkHost

java.lang.Object

org.cloudbus.cloudsim.Host

org.cloudbus.cloudsim.network.datacenter.NetworkHost

public class NetworkHost
extends Host

NetworkHost class extends Host to support simulation of networked datacenters. It executes actions related to management of packets (send and receive)other than that of virtual machines (e.g., creation and destruction). A host has a defined policy for provisioning memory and bw, as well as an allocation policy for Pe's to virtual machines.

Method Detail

updateVmsProcessing

public double updateVmsProcessing(double currentTime)

Requests updating of processing of cloudlets in the VMs running in this host.

Overrides:

updateVmsProcessing in class Host

Parameters:

currentTime - the current time

Returns:

expected time of completion of the next cloudlet in all VMs in this host. Double.MAX_VALUE if there is no future events expected in th is host

getMaxUtilizationAmongVmsPes

public double getMaxUtilizationAmongVmsPes(Vm vm)
