Integrating the SDN concept with fog computing increases the performance of IoT. The SDN controller keep registry, and manages resources allocation to all IoT items.

The novel orientation over Optical label switched network consists in computing the performance metrics based on network resource. In this case, it is preferable to define relationship between traffic parameters and network parameters including loss, delay, utilization ratio...etc.
The following paper can be used: Dynamic connection establishment and network re-optimization in flexible optical networks.
