Autonomous decentralized system supporting for fault-tolerance and on-line maintenance of communication software

Abstract

Recently several kinds of intelligent telecommunication services such as a free phone, a virtual private network have been provided. The number of these intelligent services will increase and various types of service will be provided on the future telecommunication network. Under this situation, more refined and detailed service management is required. This means that a GW (gateway) system which realizes flexible circulation of information between NEs(network elements) and OpSs(operation systems), and among OpSs is necessary. In this paper, we propose a model and a platform for the GW system based on the autonomous decentralized system concept in order to attain the above requirement. The proposed model and platform also attain fault tolerance and on-line maintainability of the application software installed in the GW system.
