Evolutionary approach to broadband services and network

Abstract

The demand for broadband services is increasing. However, it is very difficult to specify future demand. Under these circumstances, individual systems must be developed to meet varying demands, while each system should have the capability of being merged into a future broadband network.This paper presents broadband network evolution. First, broadband commercial services as well as prospects for future services are reviewed. Next, the present state and trends in technologies for broadband services are described. Finally, an evolutionary approach to broadband ISDN based on the module concept and unified architecture is proposed.
