Network as-a-service: The WebRTC case: How SDN & NFV set a solid Telco-OTT groundwork

In this paper, we consider networking technologies like Software-Defined Networks (SDN) and Network Functions Virtualization (NFV) to analyze, as a first step, the opportunities that directly address the limitations of today´s network architectures and lay a foundation for concrete interactions between network providers and Over-The-Top (OTT) service providers. To study the strength of adopting these two emerging technologies in operator networks, we apply this analysis on the case of WebRTC communication services. Indeed, WebRTC presents significant changes in the communication model which makes it an interesting case of study. Thus, our work initiates and discusses the importance of a “Network-as-a-Service” model between network operators and OTT Communication Service Providers (CSPs) in an SDN-NFV network environment.
