Abstract:

This paper presents an algorithm for totally ordered multicast which preserves Quality of Service (QoS) guarantees. The paper assumes a QoS reservation model in which the network allows for reservation of variable bandwidth, specified by the average transmission rate and the maximum burst. As long as the application sends at the reserved rate, the network guarantees to deliver messages with bounded delays. For this model, the paper presents a totally ordered multicast algorithm that preserves the bandwidth and latency reserved by the application within certain additive constants that do not depend on the number of processes participating. This is an improvement over previous work, which gave latency bounds proportional to the number of processes. Furthermore, the presented algorithm allows for dynamic joining and leaving of processes while still preserving the QoS guarantees.
