All Implemented Interfaces:

Clearable, RequestGenerator

public class GnutantRequestGenerator

extends Object

implements RequestGenerator

This class implements a generic request generator. To create a request, the generator selects randomly (with uniform probability) a resource from a resource set, creates a generic request for that resource and assign it randomly to one of the nests included in the peernet. The number of requests that are generated for each invocation of method generateRequests can be configured through the NumberOfRequests parameter.

Field Summary

static String	EXPONENTIAL If the Selection parameter assumes this value, resources are selected randomly (with exponential distribution) from the resource set.
static String	PAR_MEAN String name of the parameter used to determine vary the mean of the keyword selection distribution.
static String	PAR_NUMBERREQUESTS Parameter name used to read the number of requests to be generated
static String	PAR_SELECTION String name of the parameter used to determine the type of selection you can use.
static String	UNIFORM If the Selection parameter assumes this value, resources are selected randomly (with uniform distribution) from the resource set.
