bcds.phison.sim
Class PmLinkFailure<V,E>

java.lang.Object
  bcds.phison.sim.PmBase<V,E>
      bcds.phison.sim.PmLinkFailure<V,E>

All Implemented Interfaces:

ProcessingModule<V,E>, WithEnvParams

public class PmLinkFailure<V,E>
extends PmBase<V,E>
implements ProcessingModule<V,E>

Process (single) link failures, that is, act upon LINK_FAILURE and LINK_REPAIR events. No recovery is attempted; once failed, connections are lost for ever. NOTE that this class supports unprotected and dedicated protections only. - 2010-09-17 Converted to a "Pm" (processing module) from the code within Sim.java.

Constructor Summary

PmLinkFailure()

Method Summary

java.lang.Object[]	getEnvParams() Returns an empty array.
void	registerLinkFailureEvent(bcds.phison.sim.PmLinkFailure.Stats st, SimEvents ev, E e, java.lang.String traf_type, TED<V,E> ted) Updates: - the number of concurrent link failures, - the list of links that have failed, - the number of connections affected by the failure, - the affected capacity, - the histogram "failure notification time".
void	run(SimEvents evtype, ConnectionInfo<V,E> rq) Empty implementation.
void	setup(SimCore<V,E> sim) Saves the parameter sim, which can later be obtained by calling the sim() method.
void	shutdown() Empty implementation.

PmLinkFailure

public PmLinkFailure()

Method Detail

setup

public void setup(SimCore<V,E> sim)

Description copied from class: PmBase

Saves the parameter sim, which can later be obtained by calling the sim() method. It also calls adaptTypes if the environment object is non-null (which should normally be).

Specified by:

setup in interface ProcessingModule<V,E>

Overrides:

setup in class PmBase<V,E>

run

public void run(SimEvents evtype,
                ConnectionInfo<V,E> rq)

Description copied from class: PmBase

Empty implementation.

Specified by:

run in interface ProcessingModule<V,E>

Overrides:

run in class PmBase<V,E>

shutdown

public void shutdown()

Description copied from class: PmBase

Empty implementation.

Specified by:

shutdown in interface ProcessingModule<V,E>

Overrides:

shutdown in class PmBase<V,E>

registerLinkFailureEvent

public void registerLinkFailureEvent(bcds.phison.sim.PmLinkFailure.Stats st,
                                     SimEvents ev,
                                     E e,
                                     java.lang.String traf_type,
                                     TED<V,E> ted)

Updates: - the number of concurrent link failures, - the list of links that have failed, - the number of connections affected by the failure, - the affected capacity, - the histogram "failure notification time".

Parameters:

ev. - The type of event.

e. - The affected link.

traf_type. - The traffic or demand type. null means "any type", i.e., global statistics.

ted. - Needed to obtain the list of connections passing thourgh e, and for accessing the graph (ted.g).

getEnvParams

public java.lang.Object[] getEnvParams()

Description copied from class: PmBase

Returns an empty array. This is the default implementation, suitable for modules that do not need additional environment parameters.

Specified by:

getEnvParams in interface WithEnvParams

Overrides:

getEnvParams in class PmBase<V,E>
