Method Summary

Modifier and Type	Method and Description
static Pair<Double,Double>	getAverageHopsAndLengthOfMulticastTrees(List<MulticastTree> trees) Returns the average number of hops (number of links) and km (summing all links) of the multicast trees in the network
static double	getRouteAverageLength(List<Route> routes, DoubleMatrix1D linkCostMap) Obtains the average route length among the current routes according to certain link cost metric.
static double	getTrafficProtectionDegree(NetPlan netPlan, NetworkLayer... optionalLayerParameter) Returns the fraction of the total carried traffic in the given layer that has at least one backup path defined.

Method Detail

getAverageHopsAndLengthOfMulticastTrees

public static Pair<Double,Double> getAverageHopsAndLengthOfMulticastTrees(List<MulticastTree> trees)

Returns the average number of hops (number of links) and km (summing all links) of the multicast trees in the network

Parameters:

trees - List of Multicast Trees

Returns:

First: average number of hops, second average length in km

getRouteAverageLength

public static double getRouteAverageLength(List<Route> routes,
                                           DoubleMatrix1D linkCostMap)

Obtains the average route length among the current routes according to certain link cost metric. Route lengths are weighted by their carried traffic.

Parameters:

routes - List of routes

linkCostMap - Cost metric per link

Returns:

Average route length

getTrafficProtectionDegree

public static double getTrafficProtectionDegree(NetPlan netPlan,
                                                NetworkLayer... optionalLayerParameter)

Returns the fraction of the total carried traffic in the given layer that has at least one backup path defined. If a layer is not defined, the defaul layer is used.

Parameters:

netPlan - Current network design

optionalLayerParameter - Network layer (optional)

Returns:

Traffic protection degree
