Fault-tolerant Controller Placement Model Considering Load-dependent Sojourn Time in Software-defined Network

This paper proposes a controller placement model that takes into account the load-dependent sojourn time at each controller while considering controller failures in a software-defined network. The sojourn time is expressed by the queuing theory. The sojourn time varies depending on the amount of loa...
