Software Defined Network (SDN) is a new type of network structure, which decouples the
data plane from the control planes, and improves network flexibility. However, this …

In software defined networking (SDN) when the number of network elements and traffic flows
escalate, a single controller cannot efficiently handle the growing load, resulting in the …

Software-defined networking (SDN) is an emit model for design and management of
network. The main difference is the decoupling of control plane from a data plane, which …

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 …

Network performance has become a crucial consideration in ensuring a flawless user
experience in the era of data-intensive applications and cloud computing. Traditional …

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 …

This work proposes an algorithm called k-Critical to solve the controller placement problem
in Software Defined Networks. K-Critical finds the minimum number of controllers to satisfy a …

In the context of wide area networks (WANs) and software defined networking (SDN),
reducing the communication delays experienced by the network devices is an important …

Software defined networking (SDN) has been proposed as a novel centralized architecture
which is capable of offering flexible network management and user quality-of-service (QoS) …

Recently, software defined networking (SDN) is a promising paradigm shift that decouples
the control plane from the data plane. It can centrally monitor and control the network …
