...On the other hand, distributed SDN controllers [400] not only increase availability and scalability of the underlying network, they can also dynamically change the load on the network links, which requires continuous monitoring for selecting optimal number of controllers and their placement in the network [395] to achieve load balancing [401], and to minimize delay and...
