In a maturing and competitive market, diminishing returns on core activities of connectivity and digital services are forcing fixed network service providers to take a fresh look at their business models. Network slicing through virtualization is a powerful and flexible way of creating new revenue streams and opening up co-investment opportunities. Virtual slices of the fixed network infrastructure can be offered in a “Network as a Service” model to internal customers (e.g. the mobile organization within a converged operator) or third parties. This model unlocks new business opportunities for service providers to serve their end-customers. Virtualization provides an open and programmable network infrastructure that allows to connect more users, more segments and more entities that would otherwise use parallel networks. The resulting sliced infrastructure provides the control and flexibility necessary to run innovative broadband services that differentiate in customer experience and invites convergence in networks for faster time-to-market and improved capital efficiency.
