  be.ac.ulg.montefiore.run.totem.domain.model.DomainChangeAdapter
      be.ac.ulg.montefiore.run.totem.domain.model.impl.UseBackupOnFailureRerouteMethod

All Implemented Interfaces:

DomainChangeListener, RerouteMethod

public class UseBackupOnFailureRerouteMethod
extends DomainChangeAdapter
implements RerouteMethod

When a lsp status changes to down, one of its backups is chosen and activated. If reusePrimary is set to true, when a link becomes up, primaries on this link are activated if possible. If a primary is activated, its backups are disabled.

Description copied from interface: RerouteMethod

Starts the reroute method.

Specified by:

start in interface RerouteMethod

Parameters:

params - The parameters to initialise the reroute method. See the specific documentation of each reroute method to have a list of the supported parameters.

Throws:

RerouteMethodInitialisationException - If an error occurs during the initialisation of the controller.

stop
