The controller placement problem (CPP) is one of the main issues that need to be
addressed in the context of Software Defined Networking (SDN), especially when different …

Software Defined Networking (SDN) takes out the control plane of the network elements and
distributes it to separate entities named as controllers. The main aim of the Controller …

Software defined networks provides a global network view with centralized management. To
maintain the network configuration, multiple controllers are required. The network …

Software defined networking (SDN) offers centralized network management and effective
resource utilization by offloading the intelligent control plane, responsible for routing and …

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 …

The newly emerged Software Defined Networks (SDN) can apply to Wide Area Network
(WAN) for network control and management. To achieve this, a logically centralized but a …

A distinctive feature of software‐defined networking (SDN) is a logically centralized control
plane realized using multiple physical controllers. The placement of the controllers, the so …

Abstract Controller Placement Problem (CPP) is an important task in Software Defined
Networks (SDNs). Meanwhile, the assignment of switches to the controllers plays a key role …

In large-scale software-defined networks (SDNs), multiple controllers are deployed. Each
controller has a logically centralized vision of the network that is used to manage a set of …

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 …
