Class CACEvent

java.lang.Object

SimEvent

com.net2plan.interfaces.cacSimulation.CACEvent

public class CACEvent
extends SimEvent

Provides a set of events to be used in the CAC simulator. These events are:

• Connection request: A new connection request arrives to the system
• Connection release: The holding time for a connection have just finished

Although the CACEvent class is common for all events, its meaning (i.e. action type) depends on the constructor used to get an instance. Take a look on the description of the constructors to obtain more information.

Constructor Detail

CACEvent

public CACEvent(double eventTime,
        int demandId,
        double durationInSeconds,
        double trafficVolumeInErlangs,
        java.util.Map<java.lang.String,java.lang.String> attributes)

Constructor to define a 'connection request' event.

Parameters:

eventTime - Arrival time of the request

demandId - Demand identifier

durationInSeconds - Duration (in Erlangs)

trafficVolumeInErlangs - Traffic volume (in Erlangs)

attributes - Map for user-defined attributes. The key (String value) in the map will be the attribute name and the value (String value) will be whatever value is stored in that attribute. If null, it will be assumed to be an empty HashMap
