Detailed Description

Auxiliary class to implement state-based sources, such as ON-OFF sources. A state lasts for a given duration, generating data units of samplesize bits at a given rate.

Constructor & Destructor Documentation

SourceState::SourceState (  Distrib *  duration, Distrib *  interarrival, int  samplesize )

The distribution objects will be deleted by the destructor. Parameters: duration  pointer to a distribution that describes the permanence time in this state. interarrival  pointer to a distribution that describes the interarrival process between packets. samplesize  constant size, in bits, of the packets generated in this state. Note: it generates and enqueues a complete burst, to avoid wasting time. Hence, the state duration must be finite. If this is not the case, don't use this NetElement.

SourceState::~SourceState (  void   )  [virtual]

Deletes the distribution objects.

Member Function Documentation

timeunits SourceState::GetDuration (  void   )  const

Returns: next permanence time, in timeunits, in this state, according to the duration distribution.

timeunits SourceState::GetInterarrival (  void   )  const [virtual]

Returns: time to wait to generate the next packet, in timeunits, according to the interarrival distribution.

int SourceState::GetSampleSize (  void   )  const

Returns: constant size, in bits, of the packets generated in this state.
