The controller placement problem (CPP) is one of the main issues that need to be
addressed in the context of Software Defined Networking (SDN), especially when different …

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

The Internet of Things (IoT) has transformed our interaction with the world by connecting
devices, sensors, and systems to the Internet, enabling real-time monitoring, control, and …

A distributed control plane is more scalable and robust in software defined networking. This
paper focuses on controller load balancing using packet-in request redirection, that is, given …

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 …

This paper proposes a controller placement model that takes into account the load-
dependent sojourn time at each controller while considering controller failures in a software …

The advent of the Software-Defined Networks (SDNs) has caused the control plane on the
switches to be moved to a separate part of the data plane. Failure of a single controller …

This paper proposes a controller placement model that takes into account the load-
dependent sojourn time at each controller while considering controller failures. The sojourn …

Aiming at the problems of uneven distribution of ground users, reliability fluctuation of nodes
and links and frequent switching of controller groups in software-defined satellite networks, a …

Abstract Software-Defined Networking (SDN) revolutionizes network flexibility by decoupling
the data plane from control planes, employing a logically centralized yet physically …
