Controllers are the key component of Software-defined Network (SDN) architecture. Given
the diversity of open SDN controllers, the following question arises for the network …

This paper proposes a distributed controller placement problem that finds out the pareto
optimal solutions minimizing the switch-to-controller delay, controller-to-controller delay, and …

One of the problems raised in software-defined networks (SDN) is to determine the number
and installation location of controllers so that the implementation cost reduced, and the …

In Software Defined Networks (SDN), controllers should ideally be optimally placed to
preserve the minimal response time between the controllers and the forwarding nodes in the …

Abstract Software Defined Network (SDN) has become an increasingly popular network
architecture as it provides flexible global network management by decoupling the control …

Through decoupling the data plane from the control planes, the Software Defined Network
(SDN) improves the network flexibility and has gained much attention from both academia …

The fundamental idea behind Software Defined Networking (SDN) architectures is to
decouple the control plane and data plane of the network to simplify the complexity of the …

Abstract Controller Placement in Software Defined Network is a crucial problem as the
performance of a network not only depends upon the number of controllers deployed but on …

Software defined networking (SDN) is a modern and upcoming standard in today's network
as it centralizes the network intelligence by separating the control plane from the forwarding …

The Software Defined Networking (SDN) paradigm has shifted the network intelligence from
the network devices to the centralized controller. The controllers are placed in a distributed …
