Moving the Network to the Cloud: The telco digital transformation through the convergence of wireless, optical and cloud

Software Defined Networking (SDN) and Network Function Virtualisation (NFV) have recently changed the way we operate networks. By decoupling control and data plane operations and virtualising their components, they have opened up new frontiers towards reducing network ownership costs and improving usability and efficiency. Recently, their applicability has moved towards public telecommunications networks, with concepts such as the Cloud Central Office (cloud-CO) that have pioneered its use in access and metro networks: an idea that has quickly attracted the interest of network operators. By merging mobile, residential and enterprise services into a common framework, built around commoditised data centre types of architectures, future embodiments of this Central Office (CO) virtualisation concept could achieve significant capital and operational cost savings, while providing customised network experience to high-capacity and low-latency future applications.
The presentation provides an overview of the current network disaggregation trends that are leading to the virtualisation/cloudification of central offices, highlighting the work of the presenter over the last year on virtualisation of passive optical networks, convergence of mobile fixed and cloud network and disaggregation of optical networks.
