Summary:
We propose a teletraffic loss model of a link that accommodates different service-classes whose calls have different bandwidth requirements and come from finite sources. This arrival process is known as quasi-random. New calls compete for the available link bandwidth under the Multiple Fractional Channel Reservation (MFCR) policy. The MFCR policy allows the reservation of real (not integer) number of channels in order to benefit calls of high channel (bandwidth) requirements. The proposed model does not have a product form solution for the steady state probabilities. However, we propose approximate but recursive formulas for the calculation of time and call congestion probabilities as well as link utilization. The accuracy of the proposed formulas is verified through simulation and found to be highly satisfactory.
