This paper introduces mechanisms to correlate contents and priorities of incoming HTTP requests used for server process scheduling with the load balancing policies for Web-server clusters. This approach enables both load balancing and Web quality of service (QoS). Another contribution is a modeling and analysis technique based on stochastic high-level Petri(More)
Compared to traditional static wired network, dynamic network has a higher probability of failure due to the node mobility, constantly changing topology, as well as limited bandwidth and energy. Although the recovery strategies for service composition in dynamic network have aroused widespread concerns, most of the existing recovery strategies utilize(More)
