Application: Control apparatus, network control method and program (Patent ID: US20240048488A1)

The patent filed by Nippon Telegraph and Telephone Corp. describes a control device for managing a communication system where a network device and a virtual network device on a cloud communicate through a tunnel. The device includes a calculation unit to predict future setting entries in the virtual network device, an autoscale execution unit to scale-out or scale-in the virtual network device based on the prediction, and a control unit for routing control between an application and the virtual network device on the cloud.

The claims detail the specific functions of the control device, such as calculating the predicted value based on new clients and current setting entries, inserting tunnel settings for new clients, balancing setting entries among virtual network devices, migrating tunnel settings during scale-in, and managing routing settings during scale-out and scale-in. Additionally, the patent includes a network control method for executing the functions described in the claims and a computer-readable recording medium storing a program for implementing the network control method. Overall, the patent focuses on efficiently managing communication systems in cloud environments through predictive scaling and routing control mechanisms.
