Activating and Deactivating Repair Servers in Active Multicast Trees
Abstract. For time-constrained applications, repair-server-based active local recovery approaches can be valuable in providing low-latency reliable multicast service. However, an active multicast repair service consumes resources at the repair servers in the multicast tree. A scheme was thus presented in [10] to dynamically activate/deactivate repair servers with the goal of using as few system resources (repair servers) as possible, while at the same time improving application-level performance. In this paper, we develop stochastic models to study the distribution of repair delay both with and without a repair server in a simple multicast tree. From these models, we observe that the application deadline, downstream link loss rates, the number of receivers, and the upstream round trip time of a repair server all influence the overall value of activating an active repair server. Based on these observations, we propose a modified dynamic repair server activation algorithm that consider...
