This paper deals with Web services-based topology management mechanism in centralized network. We verify the realization of the proposed mechanism by implementing topology management system and show the most suitable development environment by measuring and comparing the performance of bandwidth usage and round-trip delay.
Next generation network (NGN) is IP based broadband and integrated network of existing communication networks. This paper defines requirements of management information to perform resource admission and path computation for single-phase resource control scheme in NGN transport stratum. We also propose high-speed resource control mechanism based on parallel(More)
