A comparison of IN and TINA through a service scenario

IN (intelligent networks) and TINA (Telecommunication Information Networking Architectures) are emerging technologies that try to address some of the critical problems in today´s fast-evolving telecom networks, by adopting architectural principles. IN is more related to physical architectures, TINA to SW architectures. This paper presents a service scenario with video conferencing and joint document editing, where IN and TINA principles co-exist. Based on the analysis of such a scenario, advantages and disadvantages of the two architectures are presented, as well as compatibility issues. The main conclusions are that there is no major incompatibility and that several advantages can be gained by combining IN with its “newer relative” TINA. The aim of presenting the analysis and the conclusions in relation to a concrete example scenario is that of reducing the level of abstraction and increasing the level of comprehension of all the concepts presented
