Abstract: With the development of cloud computing, edge computing, distributed cloud and other technologies, the future network should distribute and cooperate all kinds of service resources (computing power, data, content, etc.) intelligently and dynamically at multiple levels of “cloud edge”, and even across wide area network of multiple operators. To meet the service need and networking wish, Service Networking Over Hyper-WAN Integrated Distributed Cloud is proposed originality. Future network dual plane networking vision and layered architecture are introduced and the key technologies with cloud management platform and network operating system are proposed, such as service identification, dynamic networking routing, deterministic network and resource integrated scheduling in terms of principle and performance. Finally, the existing challenges and future directions are discussed．
