[ns] IntServ Estimator - Sample by packet instead of timeout period

[Matyas W Egyhazy]

Hi,

In the IntServ Estimator code (estimator.cc) it uses the following class 
to control the interval at which the estimator executes its load 
estimation code:

class Estimator_Timer : public TimerHandler {
public:
    Estimator_Timer(Estimator *est) : TimerHandler() { est_ = est;}
   protected:
    virtual void expire(Event *e);
    Estimator *est_;
};

I do not wish to use a timeout value based on time.  Instead, I want to 
sample after a certain number of packets (which have different sizes and 
trasmission times) have been transmitted.  Has this been done before and 
is this possible in the IntServ model?

Thanks,

Matt
