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 MI4 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 gowth 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. KeywordsATM, ADSL, Distributed Network Management, Intemet Access, and TMN lastly, we present its implementation and operation in Korea Telecom. 0-7803-7382-0/02/$17.00 02002 IEEE

This paper describes an integrated service and network management system for provisioning the point-to-multipoint reservation service (PMRS) in an ATM network. There are two major issues confronting the network service provider in relation to this service: one is to rapidly confirm the acceptability of the subscriber's reservation at subscription time, and the other is to punctually activate the reserved point-to-multipoint service. To meet these requirements, this paper proposes a service provision model (SPM) and a network resource model of bandwidth allocation timetable (BAT). This paper likewise proposes a point-to-multipoint routing algorithm composed of ordering and backtracking procedures, which can find an optimal branch point under the complex network topology and can add more destinations to the existing point-to-multipoint route. Lastly, this paper shows the feasibilities of the SPM, the BAT and the point-tomultipoint routing algorithm by means of implementation and performance analysis under the real ATM network of Korea Telecom.
