CHALLENGES IN TRANSITIONING TO SDN
How to measure the performance of SDN network?
How to benchmark SDN components?
Will this new architecture be stable and reliable?
Will the new architecture meet the scalability requirements?
How to troubleshoot and monitor the SDN network?
Will there be interoperability issues with existing networks?
