Please excuse me if it is a simple question,
Via simulation, I obtained the cumulative (discrete) distribution of the
delay of message transmissions in a network I am working with.
Its shape recalls the hyperexponential one.
Since I would like to make some analytical evaluations, I am forced to
represent the delay only with a sum of exponential distributions.
I would like to know if there is a program that could help me in this.
it should be something able to give the rates of the exponential
distributions once the trace results  are given (the error and the
number of exponential should be a parameter, too).

Thanks for your help
