Abstract:

In this paper we present a proxy based middleware that is able to adapt the exploitation of services in SOAs according to the client profile. We focus on the possibility of adapting a multimedia service to client capabilities by means of a brokering activity and a platform reconfiguration.The platform is composed of several software agents acting as proxies, which intercept, process and forward incoming messages to the next agent, till the request is sent to the brokered provider. On the backward path the agents are able to adapt the content of returned responses. Proxies are dynamically created and configured. We describe the design of platform architecture and the personalization mechanisms. We show how a client application can be extended in order to exploit such platform facilities. A prototypal implementation is presented and some preliminary performance results are discussed.
