Most telephone companies have a reputation for taking a long time to develop services. Software defined networking (SDN) and Network Function Virtualization (NFV) are new approaches to next generation network architecture for operator networks that have received much discussion as architectural approaches to enhance the operators' ability to innovate. While these approaches to network architecture are important, they only cover part of the problem. SDN allows innovation of network management and transport, including IP routing. NFV allows innovation about where service components are deployed. But a fundamental requirement for any next generation architecture is support for rapid, cross-domain service innovation. In this paper, we discuss Service Provider SDN (SP-SDN), an architectural approach to rapid service innovation based on exposure of functionality for cross-domain control at the service layer. The functionality is exposed through a Telco Platform as a Service (Telco PaaS) API. The API consists of Web-style interfaces that feature abstractions crafted by suppressing detail irrelevant for the majority of the created services. The control spans mobile, fixed and cloud operator networks, allowing the rapid and flexible provisioning of services across all three domains. Two examples of prototype systems built with SP-SDN are presented. The result will allow operators to radically reduce the time required to configure new services, and even enable operators to delegate service configuration to users through a cloud-based service portal.
