The controller placement problem [PDF]
Proceedings of the first workshop on Hot topics in software defined networks, 2012 Network architectures such as Software-Defined Networks (SDNs) move the control logic off packet processing devices and onto external controllers. These network architectures with decoupled control planes open many unanswered questions regarding reliability, scalability, and performance when compared to more traditional purely distributed ...

Controller placement methods analysis [PDF]
2016 6th International Conference on Information Communication and Management (ICICM), 2016 Software-Defined Networking (SDN) offers flexibility and programmability to the network infrastructure through the introduction of a controller. However, the controller introduces extra delay into the system as new data flows must query the controller for instructions of how to route traffic. This becomes an increasing problem for large scale and delay
