A Review of and Prospects for Network Operating System Research
The network operating system ( NOS ) is the key to breaking through the manageable and uncontrollable limitations of large-scale wide area networks.The future NOS is the brain of network that provides intelligent, secure, flexible, and customized network capabilities, and it promotes the Internet's evolution from consumption to production.We aim to achieve the manageable and controllable network, analyze the current research, and put forward the concept, system, and framework of NOS.From systematically dividing NOS into three layers ( network element operating system, large-scale network operating system and cloud-network integrated operating system ) , the framework of data plane-control plane-service plane is explored.Key technologies such as large-scale deterministic transmission, new transmission control protocols and super-powerful computing networks are tackled.The goals and development trends of NOS are revealed.The research progress, target architecture and development trend of NOS are studied, and visions for potential application are summarized.
