Abstract: Service providers (SP) are constantly attempting to match their network to cater to rapidly evolving offerings from content providers and digital application providers. Layered and siloed architecture in tradition Service Provider Network, requires higher management and operational costs and pose challenges in rapidly scaling. In order to solve these problems, alternative approaches are being tried out. Naturally, the approach from equipment manufacturer (OEM) could be different from that of Operator consortium or open-source community. Hence it’s prudent to visualize these three alternative architectures side-by-side and analyse them simultaneously. This paper focuses on analysing these three alternative architecture approaches with respect to each other. This analysis brings out the common features as well as key differences in these three approaches. Additionally, the analysis presented in this paper enables a practical insight into offered choices, provides a new tool to check fitment of the solution and provides a ready list of key design considerations. At present, no other article covers these useful guiding points and is a unique contribution.
