REQUEST FOR A NEW SCHEME OF INTERNET INTERCONNECTIONS AND NETWORK USAGE CHARGING FOR NEXT GENERATION INTERNET SERVICES

Since ITU(International Telecommunication Union) started to study the next generation Internet architecture such as NGN(Next Generation Network) a couple of years ago, the need to develop a new Internet interconnection and network usage scheme has been growing. Introduced first, in this study, is a necessity to develop an effective framework for NGN usage charging. We start with presenting an technical architecture of NGN for enabling an end-to-end QoS(Quality of Service) platform with committed SLA(Service Level Agreement) among NPs(Network Providers; e.g., ISPs and telcos) and SPs(Service Providers; e.g., VoIP(Voice over IP) and web portals). Furthermore, special emphasis is given to identifying key economic factors for establishing a viable and efficient solution so that it can create a promising marketplace for the next generation Internet.
