Distributed networking system for Internet access service

The number of ADSL subscribers in Korea Telecom is remarkably increasing by as many as eight hundred new subscribers every day, with a total number now already at 3 million. Because of such a large number of customers, we need a systematic networking system that can easily accommodate the explosive growth in the number of ADSL subscribers, and efficiently and uniformly manage the various heterogeneous network equipments that are increasing in proportion to the growth of ADSL subscribers. This paper, thus, proposes the distributed networking system architecture for Internet-access service provision using ATM over ADSL. In this paper, we describe the hierarchical network model in deploying ADSL services across the ATM access networks, which can easily accommodate the explosive growth ADSL subscribers in the future. In addition, this paper describes the distributed networking system and its capability to provide a systemic network management using the principal networking concepts of service ordering, addressing, routing, adaptation and switching. All of the networking system components with CORBA objects in favor of the distribution and location transparency are defined and described using the CORBA interface description language (IDL) for commonality. Lastly, we present its implementation and operation in Korea Telecom.
