Design of a Ros Corba Gateway for Inter-operable Intelligent Networking Applications

The key to introducing CORBA-based object-oriented technologies in the real-time telecommunications signaling environment is to ensure interoperability by maintaining the existing, standard protocols using Signaling System No. 7 (SS7) for the external communication interface between telecommunication equipment. It is anticipated that there will initially be islands of CORBAbased implementations which will have to interwork with the more widely deployed “legacy” systems. As signaling applications, such as Intelligent Networks (IN), are defined using the concepts and constructs of the Remote Operations Service (ROS), interworking requires that a gateway serve as a “translator” of operation invocations and their returns between the ROS and CORBA domains. Previous work by the authors had defined the “specifications translations” for such a gateway, i.e., the algorithmic mapping of various ROS concepts and constructs defined in ASN.1 to those of CORBA using IDL. In this paper we provide the “interaction specifications” for such a gateway, namely the dynamic aspects of ROS-to-CORBA mappings. These include extending the CORBA object services to support the ROS concepts of “association contract” and “connection package” as well as the mapping for the respective naming schema as well as the message formats in the two domains.
