Performance testing of a TINA platform

The TINA architecture specifications are well-known and have been available for many years. Experiences have been gathered with prototypical implementations of the TINA architecture or parts of it. These implementations have shown the benefits of the generic concept of TINA for surrounding distributed telecommunication services. Most of the implementations use new object-oriented implementation languages like C++ or Java and communication architectures like CORBA. However, up to now the question of the performance and satiability of TINA-conforming implementations, i.e., their eligibility for real applications with thousands of simultaneously acting users, still remains. This paper reports performance test results made with the TINA platform implementation at GMD FOKUS, which is based on C++, CORBA and Windows NT. The tests concentrate on the access session part of the service architecture (including subscription). The paper discusses the basic concepts of a flexible performance test architecture for distributed systems based on CORBA technology. Concrete performance test results are given, analysed and evaluated
