Abstract
In this paper, we analyze overload control for composite web services in service oriented architectures by an orchestrating broker, and propose
two practical access control rules which effectively mitigate the effects of severe overloads at some web services in the composite service. These two rules aim to keep overall web service performance (in terms of end-to-end response time) and availability at agreed quality of service levels. We present the theoretical background and design of these access control rules as well as performance evaluation results obtained by both simulation and experiments. We show that our access control rules significantly improve performance and availability
of composite web services
