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...
Clouds and grids are distributed resource infrastructures that are subjected to both on demand as well as Advance reservation (AR) requests. Matchmaking or assigning an appropriate resource to an advance reservation request is an important operation performed by the resource management middleware. Most existing research on matchmaking strategies uses a priori knowledge of the local scheduling policy...
An XML publish/subscribe system is based on filtering XML message streams for a large number of subscriptions expressed in XPath. A major issue on an XML-based publish/subscribe system is its performance. As the number of XML documents and XPath-based subscriptions increases in the system, to provide XML filtering efficiently becomes a challenging problem. Hence, there is an urgent need for optimization...
