Blocking Probability Calculation in a FAG with Bandwidth Reservation

Abstract

This paper presents a new method for blocking probability calculation in the full-availability group (FAG) with multi-rate traffic streams and bandwidth reservation. The proposed method is based on Iversen convolution algorithm worked out for systems without bandwidth reservation. The algorithm consists in calculation of system state probabilities by the convolution operation. In the paper special attention is paid to the method of calculating state probabilities in a reservation space of the system. Analytical results of the blocking probabilities in the FAG with bandwidth reservation, obtained on the basis of the proposed method, are compared with simulation results.
