Relying upon a single centralized controller in Software-Defined Networks may lead to
scalability problems. To make the network scalable and keep latency low for wide area …

Controller placement is a key problem in software defined networks (SDNs). Previously, the
solution to this problem only focused on propagation latency but ignored the load of …

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 …

Software Defined Network (SDN) is an emerging network paradigm which provides a
centralized view of the network by decoupling the network control plane from the data plane …

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 …

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 …

Controller placement problem (CPP) is a key issue for Software-Defined Networking (SDN)
with distributed controller architectures. This problem aims to determine a suitable number of …

In order to simplify the management of the traditional network, software-defined networking
(SDN) has been proposed as a promising paradigm shift that decouples control plane and …

Software-Defined Networking (SDN) is a network paradigm introduced to overcome the
inherent challenges of traditional networks. Its architecture is either deployed with a single …

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