The evolution towards future communication systems is strongly influenced by increasing transmission capacities, changing service requirements and the emerging ATM technology. The next generation of high-performance local and metropolitan area networks has to be designed including control schemes which provide high throughput while simultaneously supporting real-time services. The slotted ring architecture enhanced by spatial slot reuse is one potential approach for data transmission and admission control in distributed Gbit/s networks. Various concepts have been proposed for an efficient medium access control which maintains fairness and bounded access delays. By using simulation results, this paper compares the performance of several protocols: ATMRing (ATMR), CRMA-II (Cyclic Reservation Multiple Access) and MetaRing. First, the differences in their basic mechanisms are generally analysed applying saturated traffic scenarios. Then the behaviour in a multi-service environment is discussed, with particular regard to the requirements of universal broadband services. It is shown that all approaches offer efficient bandwidth sharing mechanisms. They overcome the well-known trade-off between high throughput and strong real-time requirements by providing extended bandwidth for user data and suitable end-to-end delays. Their performance, however, is quite sensitive to the actual network conditions and chosen protocol parameters.
