reuseComputedPath

protected boolean reuseComputedPath

Constructor Detail

LinkLoadStrategyAdapter

protected LinkLoadStrategyAdapter()

Set the default property value : ECMP = false, stopOnError = true, spf = CSPF.

Method Detail

isECMP

public boolean isECMP()

Get the ECMP (Equal-Cost Multi-Path) property.

By default : false

Specified by:

isECMP in interface LinkLoadStrategy

Returns:

true if equal-cost multi-path is activated and false otherwise

setECMP

public void setECMP(boolean ECMP)

Set the ECMP (Equal-Cost Multi-Path) property.

Specified by:

setECMP in interface LinkLoadStrategy

Parameters:

ECMP - true if equal-cost multi-path must be activated and false otherwise

isStopOnError

public boolean isStopOnError()

Get the StopOnError property. The property StopOnError is false if the computation must continue after a NoRouteToHostException or a RoutingException occurs and true otherwise.

By default : true.

Specified by:

isStopOnError in interface LinkLoadStrategy

Returns:

false if the computation must continue after a NoRouteToHostException or a RoutingException occurs and true otherwise.

setStopOnError

public void setStopOnError(boolean stopOnError)

Set the StopOnError property. The property StopOnError is false if the computation must continue after a NoRouteToHostException or a RoutingException occurs and true otherwise.

Specified by:

setStopOnError in interface LinkLoadStrategy

Parameters:

stopOnError - false if the computation must continue after a NoRouteToHostException or a RoutingException occurs and true otherwise

getSPFAlgo

public SPF getSPFAlgo()

Get the SPF (Shortest Path First algorithm) property. The SPF is the routing algorithm used to compute the link load.

By default : dijkstra SPF implemented by the class CSPF.

Specified by:

getSPFAlgo in interface LinkLoadStrategy

Returns:

the SPF

setSPFAlgo

public void setSPFAlgo(SPF spf)

Set the SPF (Shortest Path First algorithm) property. The SPF is the routing algorithm used to compute the link load.

Specified by:

setSPFAlgo in interface LinkLoadStrategy

Parameters:

spf - the SPF to use in the link load computation

isReuseComputedPath

public boolean isReuseComputedPath()

Get the reuseComputedPath property. This property is true if the linkLoadCompution must reuse the already computed path. This can be used to speed up the computation if the previous computed paths are already good. This must be used with care. By default : false;

Specified by:

isReuseComputedPath in interface LinkLoadStrategy

Returns:

true if the linkLoadCompution must reuse the already computed path and false otherwise

setReuseComputedPath

public void setReuseComputedPath(boolean reuseComputedPath)

Set the reuseComputedPath property

Specified by:

setReuseComputedPath in interface LinkLoadStrategy

Parameters:

reuseComputedPath - true if the linkLoadCompution must reuse the already computed path and false otherwise

equals

public boolean equals(java.lang.Object o)

Specified by:

equals in interface LinkLoadStrategy

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Specified by:

hashCode in interface LinkLoadStrategy

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Specified by:

toString in interface LinkLoadStrategy

Overrides:

toString in class java.lang.Object
