This Letter investigates multi‐controller placement problem for software‐defined network
aiming at minimising the propagation latency between switches and associated controllers …

Software Defined Networking (SDN), the novel paradigm of decoupling the control logic from
packet forwarding devices, has been drawing considerable attention from both academia …

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 …

Abstract Software Defined Networking (SDN) decouples control and data planes. The
separation arises a problem known as the controller placement, ie, how many and where …

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 …

Through decoupling the data plane from the control planes, the Software Defined Network
(SDN) improves the network flexibility and has gained much attention from both academia …

Software defined networking (SDN) is a modern and upcoming standard in today's network
as it centralizes the network intelligence by separating the control plane from the forwarding …

Software-Defined Network is an emerging networking paradigm that enables intelligent and
flexible network management. Specifically, the design of the control plane is crucial …

Software defined network (SDN) is a new modern network technology which decouples
control plane and data plane to simplify network management. The separation of control …

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