Evolution trends of the converged networks and next generation networks

The evolution strategy of the converged networks towards the Next Generation Network (NGN) architecture is presented in the article. The up to date outputs and results of the standardization institutions: International Telecommunication Union - Telecommunications (ITU-T) and European Telecommunication Standards Institute (ETSI) in the area of the converged networks and NGN, as well as the research and development activities and trends of main Information and Communication Technologies (ICT) producers are taken into account in the formulation of migration scenarios and development processes of the possible conception of the future NGN architecture. Using the actual NGN conceptual model the distributed conception of the NGN architecture (individual network layers) is shortly described. Migration scenarios of IN evolution towards platforms of Converged Networks and NGN are presented. Key aspects of the evolution trends of the ICT towards NGN are also introduced. Within the presented case study, some results of the state research and development project are presented.
