Service-Oriented Software Framework for Network Management

Abstract

A network management is important in managing network elements. While hundreds of network-related new services have been created, the network management functions should have been re-coded to adapt new business rules. In addition, redundant information could be transferred repeatedly to the inter-operating systems because they request similar information. This environment brings unnecessary system development cost, and increases redundancy in the inter-operating functions. To reduce the cost and the redundancy, we propose the service-oriented software framework for network management. In order to do so, we identified common services for network management, made service specifications and service flows, and conducted service realization. Also, we present four types of services as the case studies: authentication service, SMS service, previous alarm inquiry service, and current alarm management service. Furthermore, we implemented the framework in KT to manage IP backbone networks. After adopting the framework, the system’s performance and flexibility were improved, and duplicated functionalities of the systems were reduced.
