This paper details the evolution of access network sharing models from legacy DSL to the most recent fibre-based technology and the main challenges faced from technical and business perspectives. We first give an overview of existing access sharing models, that span physical local loop unbundling and virtual unbundled local access. We then describe different types of optical access technologies and highlight how they support network sharing. Next, we examine how the concept of SDN and network virtualization has been pivotal in enabling the idea of “true multi-tenancy”, through the use of programmability, flexible architecture and resource isolation. We give examples of recent developments of cloud central office and OLT virtualization. Finally, we provide an insight into the role that novel business models, such as blockchain and smart contract technology, could play in 5G networks. We discuss how these might evolve, to provide flexibility and dynamic operations that are needed in the data and control planes.

“…Deep infrastructure virtualization, both in the central office (CO) [4] and in the PON [5] allows virtual network operators (VNOs) to deliver assured QoS even for time-critical applications. This allows cost-effective, high-capacity and low latency connectivity giving the ability to adopt cloud-RAN to maximize resource sharing in high-density cell deployment.…”

The drive towards ubiquitous communications has long been encompassed by the concept of a connected or smart city. The idea that data transfer and real-time data analysis can enhance the quality of life for urban inhabitants is compelling, and one can easily envision the provision of exciting new services and applications that such an information-driven city could provide. The challenge in achieving a truly smart city stems largely from communications technologies -fixed line, wireless, backhaul, and fronthaul -and how these are combined to provide fast, reliable, and secure communications coverage.Here, we report on the key observations from the Connected OFCity Challenge competition, held at the Optical Fiber Communications Conference (OFC) 2017, which addressed the fixed and wireless access network requirements for smart cities. It is shown that, from a technological perspective, future optical networks will be capable of securely supporting extremely low-latency and high bandwidth applications. However, as shown by using a Networked Music Performance as a particularly challenging example application, how readily this is achieved will depend on the interplay between wired and wireless access services.
