Abstract: 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 net methods for QoS-aware load balancing. We propose an approximate analysis technique to reduce the complexity of the model.
Keywords: load balancing; performance analysis; stochastic high-level Petri net; web quality of service; web-server cluster.
