  • Publication number: 20230336955
    Abstract: Systems and methods described herein provide deployment optimization service. A network device in a network receives an order for virtual network function (VNF) deployments at network edge locations. The network device maps a radio access network (RAN) topology for the network edge locations. The network device identifies time windows to perform the VNF deployments, based on the order, historical transport and RAN utilization data, and the RAN topology. The network device selects an optimal time window to perform the VNF deployments based on stored policy rules and pushes software images for the VNF deployments to an image repository in a geographical region near the network edge locations. The network device analyzes, for the optimal time window, real-time network data for a pre-emptive condition. The network device pre-empts the VNF deployments when a pre-emptive condition is identified and initiates the VNF deployments when no pre-emptive condition is identified.
