Our IP Network will be simplified to strip out cost and complexity by taking out layers of switching and routing and moving to a robust multi-tenanted network supporting multiple lines of business.

Also our Distributed Cloud vision will require that we implement new infrastructure (NFVI) in a number of our core, edge and access locations. To support this, we will create a Data Centre topology architecture that lays out which locations will be upgraded to support what sort of virtualised network functions. Refer to Figure 5 - IP Network Simplification example below.

This Network Data Centre topology architecture will also need to be supported by a new IP network topology and exchange / access location (base station) topology. Refer to Figure 6 Example Core and Edge locations topology below.

Advances in Optical and Chip technologies will also mean that the traditional Transport area and the Routing area will collapse, with combined equipment and management systems. The main drive towards this is operational efficiency (less equipment to maintain, fewer management systems) but also key to the need is the introduction of SDN (if routing and optical have separate ‘control’ then SDN will only achieve half of its potential benefit in providing dynamic connectivity).
