This paper focuses on XML content delivery. Techniques for XML publish/subscribe delivery include unicast, flooding, IP multicast, and application-layer multicast. An important issue in the context of the state-of-the-art XML routing schemes is that the cost of filtering and aggregation is incurred at each hop. A new peer-to-peer model for XML pub/sub multicast service is described. The proposed model eliminates the redundant filtering task for intermediate nodes. A comparison of the proposed peer-to-peer model for XML multicast and the conventional application-layer XML multicast is presented. The results reveal that the proposed peer-to-peer model is much more efficient.
