<p>Systems (1) for exchanging messages (10-13,40-55) between customer devices (2) such as customer premises equipment and servers (3) such as auto configuration servers at several layers comprising a first layer such as a hyper text transfer protocol layer and a second layer such as a simple object access protocol layer are made compliant to web services toolkits by, at the second layer, allowing the customer device (2) to be a requesting party only and the server (3) to be a responding party only, for so-called server method applications as well as for so-called customer device method applications. At the second layer, the server (3) is never a requesting party and the customer device (2) is never a responding party. As a result, the development of management appliances no longer needs to be done manually and the system (1) according to the invention can be used in combination with firewalls.</p> |
