System design trajectory based on open distributed processing

The idea of open distributed processing (ODP) is an attempt to model the establishment of integrated distributed environments. It spans heterogeneous systems and extends OSI. This proposal offers new opportunities for various applications: telecommunications, intelligent networks, broadband communications, and fibre optics. The paper presents an architectural ODP model and a methodical approach to support the design trajectory of networks and information systems. It suggests three general step by step top-down approaches and their refinement by special formal descriptions according to a so-called ODP viewpoint.<
