A mediator system (and associated methods and computer program products) for mediating a communication between a client and a plurality of providers within a network is described. The mediator system may include logical machines including a first receiving machine configured to receive a request message from the client, a first sending machine configured to send answer messages back to the client, a processing machine configured to handle the received request message internally represented as a request object, a second sending machine configured to send outgoing request messages to the providers, and a second receiving machine configured to receive incoming answer messages from the providers. The machines can be scheduled separately from being executed, and the request object may be split into subrequests, where each of those subrequests may be further decomposed into subsubrequests that may be sent out in parallel to the providers.
