Cloud-Native SDN Network Management for Beyond 5G Networks with TeraFlow

TeraFlow proposes a novel secured transport Software Defined Networking (SDN) controller based on a microservice architecture. The objective is to foster innovation around SDN controller and evolve them to be suitable for beyond 5G networks. This paper presents two TeraFlow scenarios that involve automated network management to demonstrate its feasibility. The first scenario focuses on the necessary transformation of a network operator to support beyond 5G technologies. From edge, up to the transport network, SDN controllers need to include more dinamicity to support operator requirements for new types of connectivity services. The second scenario demonstrates interdomain connectivity services in an automotive scenario. In this scenario, novel techniques for domain inter-connection will be studied, as well as the load balancing of the connectivity service requests will be evaluated at cloud-scale.
