Software defined networks provides a global network view with centralized management. To
maintain the network configuration, multiple controllers are required. The network …

Software Defined Networking (SDN) presents a paradigm shift in network management and
configuration. The idea of having an externalized control plane opens many unanswered …

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 Networking (SDN) is an emerging paradigm that separates control and
data plane. This technology will be a key component in designing 5G networks that involve …

One of the most critical factors in SDN networks is the controller placement. The controller's
location determines the network delay. Reduction in network latency can help to scale the …

Abstract Software Defined Network (SDN) is an emerging approach to overcome challenges
of traditional networks. One particularly important issue in SDN architectures is that of …

The controller placement problem is one of the most important issues in designing software‐
defined networks (SDNs). In this context, one of the major challenges is the problem of multi …

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

The number of controllers required to manage the network and locations of these controllers
affect various aspects of the separated controller plane including the performance metrics …

Software defined networking (SDN) empower the service providers and enterprisers to
respond quickly to changing business requirements. Due to the logically centralized but …
