Summary

The concept of the International Mobile Telecommunications-2020 (IMT-2020) system is represented by a wide spectrum of information communication technology applications, cloud services and network infrastructure, dynamically responding to the relevant requirements of each service, whether already widely used or new. One approach to building network infrastructure is that of the software-defined network (SDN). It is described in ONF TR-526 and ITU-R M.2083.

Recommendation ITU-T Q.4061 contains: a classification of SDN controller tests; parameters, structure, sequence and methodology of SDN controller testing.
