上游充通大￥ Mapping the Subsystems Associations: SHANGHAI JIAO TONG UNIVERSITY Connectivity Describe the physical connectivity of the hardware Often the physical layer in ISO's OSI Reference Model Which associations in the object model are mapped to physical connections? Which of the client-supplier relationships in the analysis/ design model correspond to physical connections? Describe the logical connectivity (subsystem associations) Identify associations that do not directly map into physical connections: How should these associations be implemented?
