IP3 2023 – Network Monitoring (LOT 14769)

This lot is generally related to a technique to implement SDN-based network virtualization for performing monitoring tasks with a small delay and reduces total control channel consumption. Disclosed is a network hypervisor implementing software defined network (SDN)-based network virtualization consisting of a statistics virtualization module for receiving a request for individual physical resource consumption statistics for a first virtual network. The system determines whether a physical resource is shared between the first virtual network and the multiple separately managed virtual networks. Also disclosed are techniques to provide individual physical resource consumption statistics to the first virtual network and the statistics virtualization module provides respective virtual flow entry statistics to the first virtual network. The system provides network virtualization by creating a specialized virtual network for increasing the efficiency of services using the network and maximizing the utilization rate of the entire physical network. The technology may be implemented in software-defined networks, data center management systems, network performance monitoring systems, etc.
