IUSTA, a prioritized multicast ATM switch: design and performance evaluation



In this paper, a new approach has been introduced for the design of an ATM switching system. IUSTA (Iran University of Science & Technology ATM switch) is proposed as ATM switch architecture based on a knockout principle with output queuing. Intrinsic broadcast, multicast capabilities and priority functionality are important features of IUSTA.  In this paper an architectural design is provided to construct arbitrary large switches based on simple basic building blocks. By use of these features, IUSTA reaches to 10-14 for cell loss probability with the modest size component
