On the design and an implementation of broadband access management systems

This paper describes a design approach and its implementation for a broadband access management system that provides element and network management functions for FTTC (fiber-to-the-curb)/FTTB (fiber-to-the-building) access networks, and service management functions for video on demand (VOD) services. The proposed architecture is a top-down approach, and consists of four levels of basic architecture, namely, service/functional architecture, system architecture, network architecture and software architecture. By the proposed architecture, TMN compliant layered management functions are realized for the broadband access system at EML (element management layer), NML (network management layer) and SML (service management layer). By considering multi-vendor environments, the proposed management systems communicate each other via OSI protocols. Three different configurations are evaluated for EML agents, and the distributed or hybrid EML agent approaches are cost effective solutions based on current technologies. Finally, this paper shows a prototype system based on the proposed architecture.
