Business Case for NFV/SDN Programmable Networks

ACG Research analyzes three programmable High-IQ network use cases that were created by Juniper Networks. The analyses show the benefits derived from the deployment of programmable networks for service providers. A cloud customer premise equipment and virtual firewall (vCPE) use case replaces physical CPE with a simple on-premise Ethernet device and moves IP virtual private network  and firewall functions to the cloud. This produces a 36 percent five-year net present value increase as compared to the physical CPE solution. A real-time network self-optimization use case replaces manual traffic engineering processes. This produces a 27 percent five-year total cost of ownership  savings compared to the manual processes. An elastic traffic engineering use case for a national all IP core network demonstrates the advantages of an SDN solution as compared to the present mode of operations. The SDN solution reduces bandwidth and associated link capital expenses by 35 percent while maintaining all network service level agreements.
