Abstract: Comprehensive review and analysis of international research and standardization activities pertinent to Next Generation Networks (NGN) and Next Generation Internet (NGI) were provided. A strategy in developing NGI architecture was proposed based on the experience gained in development of Single physical layer Userdata transfer & switching Platform Architecture (SUPA). A brief discussion on SUPA and Ethernetoriented Physical Frame Timeslot Switching (EPFTS) was given, and how to solve QoS provisioning, highperformance switching and Internet security by using the techniques was also discussed.

Key words: Next Generatino Network (GN), Next Generation Internet (NGI), network architecture
