摘要
In this paper we present a concept for providing QoS to multicast in structured P2P networks. We show on the example of Scribe / Pastry how to enforce QoS aware tree construction in a structured P2P network. We achieve this by modifying the ID assignment method of Pastry based on the QoS requirements or peers. As a result, the multicast tree holds the QoS (bandwidth) requirements on each of its end-to-end paths. We have evaluated the proposed concept by comparing default random Pastry ID assignment with our proposed method. The results of the evaluation show that using our method all end-to-end paths in the multicast tree fullfill the bandwidth QoS requirements, which is usually not the case for default Pastry.
