Performance analysis of a new share output buffer ATM switch

This paper deals with the multi-class QoS of B-ISDN service. ATM switch should divide different classes for guaranteeing QoS of system. The buffer management mechanism (partial share output buffer) is presented. No-priority and priority scheme are adopted. Cell loss probability and delay are analyzed for no priority, high priority and low priority services. Results show the ATM switch that we propose can control the performance of system effectively.
