“…This can be done with the help of finite-source, or quasi-random input models. RQ with quasi-random input are a recent interest in modeling among others magnetic disk memory systems, cellular mobile networks, computer networks, and local-area networks with non-persistent CSMA/CD protocols, with a star topology, with random access protocols, and with multiple-access protocols, see, for example Alfa and Isotupa [1], Ali and Wei [2], Almási et al [3], Do et al [9], Dragieva [12], Ikhlef, Lekadir and Aïssani [17], Lebedev and Ponomarov [21], Wüchner, Sztrik and de Meer [31].…”
