Several scenarios have been envisioned in the present document: - One ASP within the AS. - Several ASPs within the ASP. -

5、 One ASP connected to one SGP. - Several ASPs connected to one SGP. 4.2 Overview of the Test Suite Structure The Test Suite Structures is based on the main functionalities as defined above. Figure 2 shows the Test Suite Structure. Last Sub groups may be subdivided in three subgroups: Valid behaviour
