Summary: Enhanced models of a telecommunication traffic: non-Poisson models suitable for description of calls and information within a call, information flows and traffic parameters in a service switching environment. Influence of changes in the traffic domain on the network planning methodology, including overall development scenario and evaluation of specific solutions. Network reference model, its information model and relational data base. Service switching processes, logic of telecommunications and generic functions of the switching node: operations with information streams, call and service processing, extension on service switching and control, flexible allocation of network resources. Research includes: - methods for network development form the point of view of capacity and functions, for voice, non-voice and multimedia communication, - stochastic and deterministic models, network planning and optimization algorithms, flow control procedures, - transition from information switching to service switching, formal models and methods for the synthesis of services with complex interaction with a basic call, - service provision and distributed data bases in an open environment, - functional integration of public and private, business oriented, communication systems, - workstations and software tools for telecommunications, - experimental verification, laboratory network set-up.

Keywords: telecommunications, information systems, network planning, network dimensioning, capacity expansion, information flow control, open system interconnection, multimedia communication, processing, service switching

Research goals: Overall goal is to study selected telecommunications and informatics topics relevant for dynamic development of networks, systems, services and technologies, oriented toward telecommunication needs of an information society. By integrating various types of information, different kinds of information processing and telecommunication technologies a network model is obtained where each user request can be mapped on a specific service and solved in a flexible way. Expected results are as follows: - methods for evaluating different network development scenarios with mixed circuit and packet switching capabilities, - criteria and algorithms for information flow routing in a switching network and circuit/bandwith allocation in a transmission network, - access network planning for new voice and non-voice services, local communication systems based on integrated voice and data communications, mixed circuit and packet switching and local area network, - synthesis of call processes and service switching functions using finite automata, Petri net and calculus of communicating systems formalisms, - telematic services in an open environment, information systems and data bases, - diagnostic and self diagnostic algorithms, reliability and availability models in telecommunications, - workstations based on UNIX operating system for design and management in telecommunications, - education of young researchers.
