Business partners in an extranet expect web services to be offered in a timely fashion. Replicating web services may reduce the end-to-end web service response time and add fault tolerance to the system. This paper proposes a web service replica selection framework that can be deployed in an extranet. The selection procedure is based on dynamic factors such as communication delays between the web service provider and the web service requester and the workload of the web service provider. To analyze the performance of the framework, two web service replica selection policies are simulated: minU and random.
