The controller placement problem (CPP) is one of the key challenges of software defined
networks (SDNs) to increase performance. Given the locations of n switches, CPP consists …

Software Defined Networking (SDN), the novel paradigm of decoupling the control logic from
packet forwarding devices, has been drawing considerable attention from both academia …

Software defined network (SDN) decouples the control plane from packet processing device
and introduces the controller placement problem. The previous methods only focus on …

With the popularization and spread of SDN, the size of SDN networks is increasing; the
controller placement is a key problem in software defined networks (SDNs). In this paper, an …

Software Defined Networking moves the control plane functionalities of the network
elements to one or more external entities known as controllers. The controller placement …

Recently, a variety of solutions have been proposed to tackle the controller placement
problem in SDN. The objectives include minimizing the latency between controllers and their …

Software defined networking emerges as a promising paradigm shift that decouples the
control plane from the data plane. It has the ability to centrally monitor and control the …

In this letter, we propose a mathematical model for the controller placement problem in
Software Defined Networks (SDN). More precisely, given a set of switches that must be …

In almost a decade, Software Defined Networking (SDN) has transitioned from university
laboratories to real-life networks. As networks evolve from legacy networks to hybrid …
