Paper Abstract

The interactive multimedia service is expected to be a cornerstone of success in deploying the ATM-based access transport network. A hybrid access network architecture, which is combined with ring topology for the special community such as government and double star topology for the residential subscribers, would satisfy both service requirements of interactive multimedia-on-demand and economic opportunities of an access transport network. The adoption of different topology according to subscriber segments in one access network system results from user's requirements with different network reliability and evolutionary path. Because each subscriber segment needs different traffic class in different busy hour, the utilization of the common switching platform named as head node would be maximized. The cost evaluation is performed on five alternatives of access transport network based on the sum of cabling and network node cost. The result of evaluation is that only for an economic solution the double star is recommended for both the special community and the residential, while with consideration of serveability a hybrid with double star would be the optimized choice.
