Abstract
With increasing demand for faster, more reliable connectivity, next-generation transport networks must evolve toward autonomous and customer-driven network management. Software-Defined Networking (SDN) is widely used to dynamically provide high-availability, low-latency paths. At the same time, however, transport networks are heterogeneous, consisting of multiple layers (L3-L0) and operator domains, and must be able to interoperate smoothly. To meet these requirements in multi-vendor, multi-domain end-to-end network slicing, it is important to hide customer-specific implementation details from different operators. Similarly, “traffic intent modelling” is proposed as a means to abstract the required services from the customers. In this paper, we explore a standardised intent-driven multi-layer network management architecture that has been proposed by Telefónica I+D.
