4. Application example: dynamic implementation of differentiated traffic routing policies within a multi-domain slice service
The variety and complexity of connectivity services has grown steadily over the years, as network technologies have evolved. The recent emergence of 5G mobile networks has put the spotlight back on the concept of the "slice", i.e. an overlay network deployed on a physical infrastructure, which is thus broken down into logical slices, a form of virtual private network (VPN) with performance characteristics compatible with the needs of the most demanding services, from "immersive" services based on the use of virtual reality or augmented reality techniques requiring extremely low latencies, to services based on the Internet of Things deployed on a large scale.
The 3GPP initiative, which has been responsible for the specifications of successive generations of mobile networks for several years now, has even undertaken to document the characteristics - in terms of latency,...
