Interface LinkLoadStrategy

All Superinterfaces:

LinkLoadComputer

All Known Implementing Classes:

AbstractLinkLoadStrategy, BasicIGPShortcutStrategy, IGPShortcutStrategy, OverlayStrategy, SPFLinkLoadStrategy

public interface LinkLoadStrategy
extends LinkLoadComputer

Define the behavior of a link load computation stategy. Different strategies are shortest path first, basic IGP shortcut, IGP shortcut, etc. Theses strategies of link load computation are implemented using a strategy pattern.
Three properties can be used to control the computation :

• ECMP : true if equal-cost multi-path is activated and false otherwise. By default : false.
• SPF : specifies the shortest path first algorithm to use. By default dijkstra SPF implemented by the class CSPF.
• tm : The traffic matrix to use for the computation

Method Detail

setTm

void setTm(TrafficMatrix tm)

Sets the traffic matrix to use with computation

Parameters:

tm -

isECMP

boolean isECMP()

Get the ECMP (Equal-Cost Multi-Path) property. By default : false

Returns:

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

setECMP

void setECMP(boolean ECMP)

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

Parameters:

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

getSPFAlgo

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.

Returns:

the SPF

setSPFAlgo

void setSPFAlgo(SPF spf)

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

Parameters:

spf - the SPF to use in the link load computation

equals

boolean equals(java.lang.Object o)

Description copied from interface: LinkLoadComputer
