Description In the past few years, networks of workstations (NOWs) and clusters, based on high-speed local area networks (LANs), have emerged as a serious alternative to supercomputers and high-performance servers. Meanwhile, applications demanding real-time network services have also suffered a substantial growth. In order to use NOWs for distributed real-time processing, a topology change and faulttolerant mechanism that guarantees the maximum latency or the minimum bandwidth in the worst case must be provided. Up to now, the backup channel protocol (BCP), based on real-time channels, provides fault-tolerant realtime services. But in this approach, fault tolerance is limited by the alternative paths provided by the routing function to establish the backup channels and topology change tolerance is not supported. On the other hand, dynamic reconfiguration updates the routing tables without stopping user traffic when a topology change or fault occurs. However, dynamic reconfiguration by itself does not provide neither quality of service nor real-time services, but it provides support for an additional mechanism designed to meet realtime requirements.
