SDN/Cloud Solutions for Intent-Based Networking

The approach of SDN and NFV integration in cloud environment for Intent-Based Networking has been proposed. The method to provide the required QoS level is developed. For this purpose in the hours of the largest load, in case when all physical resources of the network are used, proposed to deploy additional network resources in the cloud. And vice versa, when the network load is lower-undeploy not used resources. This will allow us to unload the physical network and maintain the required QoS level. Also, since this process will occur automatically- we can minimize the human factor for setting up equipment and reduce network elements deploying time to a minimum. This approach can be used for both SDN switches and SDN controllers. Proposed to serve in cloud traffic that is not sensitive to sending time and delays. It will unload the physical network for sensitive services.In this paper we present the QoS balance formula for the hybrid network (physical and in cloud) and the scheme of such network is presented. The advantages and disadvantages are analyzed.
