....provided by these technologies. 3.3.3.1 Background and history TINA was propounded by a consortium consisting of service providers and their suppliers of software, computer and telecommunications equipment. This alliance was formally announced in an international symposium in Japan in late 1992 [Dupuy95], and began its work in early 1993 [Pavon96] The formation of the consortium reflected some exasperation and impatience with telecommunications standards setting procedures, and bodies, felt to be out of touch with the new market realities [Marshall95] reflected in particular in the four year ....

....computing and object orientation within and without prior research projects and prototype work carried out separately by consortium members. It was envisaged that, rather than having many small groups working on similar issues, co operation would enable more effective and rapid progress [Dupuy95]. With this in mind, a core team of about forty engineers was assembled at Bellcore to specify, validate and refine the architecture with the aid of sample services. The first two architectural drafts were delivered to member companies at the end of 1993 and 1994, others following in March 1995, ....

For example the Telecommunications Information Networks Architecture Consortium (TINAC) encourages interoperability and the advancement of the technology in this arena [10]. TINA has adopted CORBA as part of its architecture but as yet very little in depth work has been published on performance at scale issues. Real time (RT) CORBA has recently been receiving a lot of research attention [11] 3] but this early work is focused on applications such as avionics and ....

This architecture pays special attention to service management, and it takes into account interworking with current TMN infrastructure at the network management layer.

Instead, top down service architecture merits attention. TINA (Telecommunications Intelligent Network Architecture, e.g. DUP 95] offers a much higher level framework for defining services.

The technical problems associated with this approach are currently being tackled, for instance in the context of CORBA [18] and TINA [9]. However, if a client wants to use the services of some provider he has never heard of and whom he does not trust and if the provider needs some con dential information from the client, in order to provide the service, there is a dilemma. Trust based on reputation is diOEcult and expensive to ....
