Direct Known Subclasses:

DynamicLoadBalancing

public abstract class DynamicLoadBalancingBase
extends BaseLoadBalancing

This is the base class for every tailored dynamic load balancing approach. Its collects the load information from the running LoadMeasureAgent and accumulates them in the local attribute.

Constructor Detail

DynamicLoadBalancingBase

public DynamicLoadBalancingBase(LoadMeasureAgent loadMeasureAgent)

Default constructor of this class.

Parameters:

loadMeasureAgent - the running load agent of the system

Method Detail

action

public void action()

Overrides:

action in class BaseLoadBalancing

setMeasurements

protected void setMeasurements()

This method transfers the measurement data from the loadAgent to this class. Do NOT override!!

refreshCountingsAndLists

protected void refreshCountingsAndLists()

Here some important counting will be done by default.

updateLoadInfo4JVMandMachine

protected void updateLoadInfo4JVMandMachine(java.lang.String newContainerName)

Updates the local load information if a new container was started. These are in detail the local variables BaseLoadBalancing.currThresholdExceededOverAll, loadMachines4Balancing and loadJVM4Balancing.Additionally the method refreshCountingsAndLists() will be invoked at the end.

Parameters:

newContainerName - the new container name

See Also:

BaseLoadBalancing.currThresholdExceededOverAll, loadMachines4Balancing, loadJVM4Balancing, refreshCountingsAndLists()

startRemoteContainer

protected java.lang.String startRemoteContainer()

This Method can be invoked, if a new remote container is required. If the container was started the method returns the new containers name and will update the local information of BaseLoadBalancing.currContainerLoactions and BaseLoadBalancing.currContainerBenchmarkResults.
Additionally this method will update the load information for machines and JVM by invoking updateLoadInfo4JVMandMachine(String).

Overrides:

startRemoteContainer in class BaseLoadBalancing

Returns:

the name of the new container

See Also:

BaseLoadBalancing.currContainerLoactions, BaseLoadBalancing.currContainerBenchmarkResults

startRemoteContainer

protected java.lang.String startRemoteContainer(RemoteContainerConfig remoteContainerConfig)

This Method can be invoked, if a new remote container is required. If the container was started the method returns the new containers name and will update the local information of BaseLoadBalancing.currContainerLoactions and BaseLoadBalancing.currContainerBenchmarkResults.
Additionally this method will update the load information for machines and JVM by invoking updateLoadInfo4JVMandMachine(String).

Overrides:

startRemoteContainer in class BaseLoadBalancing

Parameters:

remoteContainerConfig - the remote container configuration out of the Project

Returns:

the name of the new container
