Software Defined Networks (SDN) is the emerging network paradigm which devises the
control plane of the communication from the data plane and makes the network design …

Controller placement issue (CPI) in software-defined networks (SDNs) describes the
controllers' number, location, and assigning of forwarding devices to controllers. Recently …

The expansion of networks, the emergence of new technologies and the proliferation of state-
of-art telecommunication devices for over two decades increased the security threats. Since …

The main characteristics of Software-Defined Networks are the separation of the control and
data planes, as well as a logically centralized control plane. This emerging network …

To further improve Software Defined networks performance, robustness and load balancing,
it is valuable to determine how to optimally deploy controllers against links failure. In this …

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 …

Although the popularity of Software-Defined Networking (SDN) is increasing, it is also
vulnerable to security attacks such as Denial of Service (DoS) attacks. Since in SDN, the …

The proliferation of connected devices and data traffic leads to the design of “Software
Defined Network”(SDN) that separates control logic from data forwarding logic for effective …

With the rapid growth of computer devices, network communication faced different
challenges from network management to traffic engineering. Software-Defined Networking …

Software-defined networking (SDN) is an agile and flexible computer network architecture
that allows a quick and efficient response by the network administrator to any changes. A …
