Toward a multiplane framework of NGSON: a required guideline to achieve pervasive services and efficient resource utilization

The next generation service overlay network will enable the provision of pervasive services over a common IP-based transport infrastructure. However, along with the service consolidation over IP and the rapid increase of network scale, the task of service and network management has become extremely complex and disordered. Efforts are being made in various areas, such as SOA, web services, IMS, P2P/CDN overlay, and cloud computing, to achieve a scalable, secure, converged, and selfmanaged service network framework to shorten the time to market of new services, as well as lower the management costs of network/service providers. Nevertheless, these technologies are not developed in a coordinated manner for optimal scalability, resource utilization, and QoS performance. In this article, we propose a multiplane framework (MPF) for NGSON based on the integration of service composition, management, and delivery, which is a top-down reference model to achieve pervasive services and efficient resource utilization.
