Class RandomSizeDistribution

java.lang.Object

ds.funnel.traffic.component.sizedistribution.RandomSizeDistribution

All Implemented Interfaces:

PacketSizeDistribution

public class RandomSizeDistribution
extends java.lang.Object
implements PacketSizeDistribution

RandomSizeDistribution defines a packet distribution pattern in which packet sizes are random, between some minimum and some maximum number of bytes. The default minimum size is 10 bytes, and the default maximum size is 10000 bytes. If no minimum or maximum are specified, a RandomSizeDistirbution will be created with these values. If only one size is specified, a RandomSizeDistribution will be constructed with a default minimum and maximum equal to the size specified if the given size is greater than the default minimum, or a minimum equal to the size specified and a maximum equal to the default minimum value if the given size is less than the default minimum.

Constructor Detail

RandomSizeDistribution

public RandomSizeDistribution()

Constructs a new RandomSizeDistribution with default maximum and minimum packet size values.

RandomSizeDistribution

public RandomSizeDistribution(int upperOrLowerBound)

Constructs a RandomSizeDistribution with one default parameter, and a specified minimum or maximum, depending upon the exact value specified. The default parameter will be equal to DEFAULTMINSIZE; if the specified bound is greater than this value, then the minimum size will be DEFAULTMINSIZE, otherwise, the maximum size will be DEFAULTMINSIZE

Parameters:

upperOrLowerBound - the wanted minimum (if less than the default minimum) or maximum (if greater than the default minimum) size for this RandomSizeDistribution

RandomSizeDistribution

public RandomSizeDistribution(int bound1,
                              int bound2)

Constructs a new RandomSizeDistribution with the specified upper and lower bounds on packet sizes. The bounds may be specified in either order.

Parameters:

bound1 - the first bound (either min or max) on packet sizes, in bytes

bound2 - the second bound (either min or max) on packet sizes, in bytes

Method Detail

getMinSize

public int getMinSize()

setMinSize

public void setMinSize(int newMin)

getMaxSize

public int getMaxSize()

setMaxSize

public void setMaxSize(int newMax)

setSizeBounds

public void setSizeBounds(int bound1,
                          int bound2)

getType

public int getType()

Specified by:

getType in interface PacketSizeDistribution

Returns:

an integer id number specifying the type of distribution. This should be a unique identifier for the type of size distribution generated by a given PacketSizeDistribution.

nextSize

public int nextSize()

Specified by:

nextSize in interface PacketSizeDistribution

Returns:

a size, in bytes, for the next packet to be sent following some specified distribution pattern
