....Network (IN) is a service architecture that intends to provide easy service creation and customization. IN follows the principle of separating service execution from the basic call processing at the switch, so that services can be created as separate pieces of software running at other places [8]. This separation is designed to relieve service developers of the need to know the intricate details of call processing at switches, and help them focus solely on service implementation. However, IN has completely failed to provide service inter operability across switches from different vendors ....

However, the service inter operability problem still exists. ....

....of these activities is on QoS control and resource allocation. Both approaches have found limited applicability because they are both strongly tied to ATM technology which, so far, has had little acceptance as an access network. A discussion of the strengths and weaknesses of TINA can be found in [CNIS] The CORBA technology is also being considered for Intelligent Networks as well as Wireless access and terminal mobility. In the Intelligent Network, current efforts focus on how CORBA could effectively interwork with SS7. A first approach consists in providing gateways between the SS7 network ....

....manufacturers formed the Telecommunications Information Networking Architecture Consortium (TINA C) to define and validate a common and open software architecture for the provision of telecommunication and information services. Due to the evolving character of TINA and doubts about its future [44], the use of formal methods for the design and implementation of TINA services is still in an early stage. Since TINA is built upon ODP concepts and uses CORBA (Common Object Request Broker Architecture) as underlying platform for services, results obtained from applying FMs for ODP (Open ....
