Abstract(s) :

(Anglais) In this paper we focus on access negotiation to services in decentralized commercial Grids. Besides being a resource provider, each site can play a brokering role, thus generate profit on the incoming service requests by subcontracting. In our configuration, negotiation is a point-to-point process consisting of couples request-offer messages. We present here an event-based simulator allowing specification of various policies that can affect the service negotiation process and the visualization of the information flow in the network. Further, we exploit the simulator to manage the response deadlines in the request-offer messages, so that sites accomplish their profit-maximization objectives. Simulations help to estimate an appropriate configuration of the policies depending on different Grid parameters leading to the maximization of the local profit.
