For instance, with a commercial virtual private network (VPN), there really is no need to deliver Internet termination and routing on either of the VPN-served customer premises. This function can now be virtualized and delivered from within the operator’s network at the subscriber’s demand.
This basic Network Function Virtualization (NFV) concept is actually an incredible benefit for both the subscriber and their service provider. The subscriber is in control of their Internet services, not limited by the capacities or features of a physical box on their premises. Instead, they can customize their services from a self-care web page. The operator can remove costly end routing equipment in terms of support and capital costs, in addition to delayering the IP network topology and simplifying the network edge.
The subscriber wins at every turn here with vastly improved self-care and dynamic service subscription ability. The operator wins with higher subscriber quality of experience and increased retention metrics.
