The Mobile Telco architecture is composed of a large number of expensive physical devices, each segregated in its own area. This offers little to no flexibility, making the overall architecture hardly scalable for the future. Technologies such as SDN and NFV are speaking numerous innovations in the networking landscape. One of them being Telco-over-Cloud, which can be directly applied to the Mobile Telco architecture to remove its current limitations, making it more cost-effective, flexible, powerful and easily scalable for the future.
