PERFORMANCE ANALYSIS OF A DIGITAL LINK WITH HETEROGENEOUS MULTISLOT TRAFFIC

We present a unified model to compute various performance measures whe n Poissonian and non-Poissonian (renewal) multi-slot traffic streams a re offered to a digital link in a (double) loss system. We represent t he non-Poissonian arrival process by a matrix-exponential distribution , requiring only that the inter-arrival distribution has a rational La place transform. Several distributions are considered as the non-Poiss onian traffic. The resulting model uses matrix algebraic techniques on ly, thus not requiring any complex and/or tedious transform techniques . We also incorporate various control policies in our modeling framewo rk using acceptance functions. Through our computational studies, we c onclude that the second and the third moments of the non-Poissonian tr affic have significant impact on various performance measures.
