A case study in performance, modifiability and extensibility analysis of a telecommunication system software architecture

We present a case study in architecture analysis. The analysis was conducted on a real system, the Ericsson product "GSM On the Net", in order to evaluate two alternative software architectures with respect to a set of attributes required by the customer namely extensibility, performance and modifiability. The two architectures differ because of the use of different internal protocols, session initiation protocol (SIP) versus H323, that deeply influence the structure of the system architecture.
