Abstract Software-Defined Networks (SDNs) are characterized by dividing a network
architecture in a data plane (ie, any packet-relaying nodes like switches or routers) and a …

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 …

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 …

We consider a distributed Software Defined Networking (SDN) architecture adopting a
cluster of controllers to improve network scalability and reliability. Different from previous …

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

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 …

By decoupling control plane and data plane, Software-Defined Networking (SDN) approach
simplifies network management and speeds up network innovations. These benefits have …

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 …

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 …

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 …
