Towards management of next generation networks

Abstract

Next Generation Network (NGN) is envisioned to be an inter-working environment of heterogeneous networks of wired and wireless access networks, PSTN, satellites, broadcasting, etc., all interconnected through the service provider's IP backbone and the Internet. NGN uses multiple broadband, QoS-enabled transport technologies and service-related functions independent from underlying transport-related technologies. The operations and management of such interconnected networks are expected to be much more difficult and important than the traditional network environment. In this paper, we present an overview of the current status towards the management of NGN and discuss challenges in operating and managing NGN. We also present the operations and management requirements of NGN in accordance with the challenges. We then present standardization activities of NGN management and some of the notable research and development efforts related to NGN management.
