Framework of network service orchestrator for responsive service lifecycle management

NFV is expected to reduce costs and provide an agile new service. To achieve OPEX reduction and providing agility of service lifecycle management, we need to improve the responsiveness of service lifecycle management by reducing the turnaround time of creating, repairing and deleting a network service. Although orchestrator is defined in NFV architecture, the architecture is relatively new and a reference model of NFV orchestrator is partially immature. In this paper, we propose a framework and the implementation of network service orchestrator for responsive service lifecycle management. In addition, we show that our orchestrator can reduce the time of creation, repair and deletion of a virtualized EPC network service as an example by experiments.
