Ethernet has been the dominant local area network architecture in the last decade, and we believe that it will remain popular because of its cost-effectiveness and the availability of higher-bandwidth Ethernets. We present the design of a software-based timed-token protocol called RETHER that provides real-time performance guarantees to multimedia applications without requiring any modifications to existing Ethernet hardware. RETHER features a hybrid mode of operation to reduce the performance impact on non-real-time network traffic, a race-condition-free distributed admission control mechanism, and an efficient token-passing scheme that protects the network against token loss due to node failures or otherwise. Performance measurements from a prototype running on 10-Mbps Ethernet and 100-Mbps Fast-Ethernet indicate that up to 60 of the raw bandwidth can be reserved without deteriorating the performance of non-real-time traffic significantly. This scheme is consistent with the ISSLL over LANs framework described in {[}7{]}.}, }
