A seismic shift is underway in today’s networking market. Connectivity services, while vital to the efficient operation of modern business, are becoming a commodity. Layering services in addition to connectivity is seen as a viable and valuable approach to deliver what end-users really want, yet the opportunity for simply layering complexity onto an already complex environment constrains its rollout at scale. Techniques such as ZTP, service scripting, SDN/NFV, and LSO address this complexity, so these value-added services can be rolled out en masse without breaking the service provider’s business case.
