Software-Defined Networking (SDN) is a developing architecture that provides scalability,
flexibility, and efficient network management. However, optimal controller placement faces …

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

Abstract In Software-Defined Networking (SDN), the control and data planes are decoupled,
leading to a more programmable and efficient network management. In this paper, the …

Software-defined networking is a new network model proposed to solve the complexity of
traditional network problems and facilitate dynamic network operation and management …

Software-Defined Networking (SDN) promises good network performance in Wide Area
Networks (WANs) with the logically centralized control using physically distributed …

One of the problems raised in software-defined networks (SDN) is to determine the number
and installation location of controllers so that the implementation cost reduced, and the …

软件定义网络(SDN) 被誉为下一代网络的关键技术. 近年来, SDN 已经成为学术界与工业界的
热点. 广域网是SDN 应用到工业界的一个重要的场景. 基于SDN 的广域网被称为软件定义 …

In this paper, we revisit a biobjective optimization problem arising in software-defined
networking with availability guarantees. The problem jointly optimizes the number of …

Software Defined Network (SDN) has been considered as one of the most promising next-
generation network solutions due to its network programmability. However, the upgrade from …

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 …
