The number of controllers required to manage the network and locations of these controllers
affect various aspects of the separated controller plane including the performance metrics …

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 networking shifts the control plane of forwarding devices to one or more
external entities known as controllers. Determining the optimal location of controllers in the …

Controller placement is an important problem in software-defined networks. If a controller
fails, there may be no controller with enough spare capacity to serve switches of the failed …

Abstract Software Defined Networking is an evolving network model wherein the control
plane is decoupled from data plane. It has become a fascinating problem to decide the …

The core concept of Software Defined Networking (SDN) is to abstract the control layer from
the data layer. SDN architectures can provide programmatic interfaces in communication …

This paper proposes a preventive priority setting model to minimize the worst-case
maximum utilization ratio against multiple controller failures in software defined networks …

Software-defined networking (SDN) is a networking architecture with improved efficiency
achieved by moving networking decisions from the data plane to provide them critically at …

The latency experienced by the switches in software defined network depends on the
number and location of the controllers in the network. The switch to controller latency, in the …

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