A framework for managing QoS and improving performance of dynamic Web content

The proportion of dynamic objects has been growing at a fast rate in the World Wide Web. However, because of additional resource requirements and the changing nature of these objects, the performance of accessing dynamic Web content has been observed to be poor in the current generation Web services. We propose a framework called WebGraph that helps in improving the response time for accessing dynamic objects. The WebGraph framework manages a graph for each of the Web pages. Both the nodes and the edges have attributes that are used in managing the Web pages. Instead of recomputing and recreating the entire page, the node and edge attributes are used to update a subset of the Weblets are then integrated to form the entire page. In addition to the performance benefits in terms of lower response time, the WebGraph framework facilitates Web caching, QoS support, load balancing, overload control, personalized services, and security for both dynamic as well as static Web pages.
