Towards Efficient Selection of Web Services

In the existing frameworks for web services there is no incentive to bind dynamically to a specific web service. However, once runtime information concerning those web services is available to the application, dynamic binding becomes advantageous over a static pre-decided one. We propose a model that provides web service clients with runtime information that is pertinent to its execution and business logic. When faced with multiple service providers who can provide the same (in functionality) service, the client can dynamically select the current best (e.g., in terms of availability for the duration of the service, reliability, and estimated response time) service provider for its required service, according to the client’s constraints and information gathered about the service providers at runtime.
