Software Defined Networking (SDN) is rapidly transforming the networking ecosystem of cloud computing data centers. However, replicating SDN-enabled cloud infrastructures to conduct practical research in this domain requires a great deal of effort and capital expenditure. In this paper, we present the CLOUDS-Pi platform, a testbed for conducting research on SDN-enabled cloud computing. As part ...

This paper gives an overview on how Software Defined Networking (SDN) principles can be applied to existing Ethernet merchant silicon considering the requirements modern networks face. We show that existing Layer 2 features specified by IEEE 802.1Q support SDN. The bridge architecture [1] supports control plane/data plane split by design and also allows for external control e.g. by an SDN Contr...

This paper presents a case for applying the principles of Software-Defined Networking (SDN) to middleboxes and end hosts. The challenges of configuring networking on network hosts resemble those addressed by SDN – numerous multi-vendor components, each with its own syntax and idiosyncratic corner cases, must be orchestrated smoothly. We have developed a prototype called NativeClick, a novel use...

Security is a major concern in computer networking, which faces increasing threats as the commercial Internet and related economies continue to grow. Our work aims to explore advances in Cyber Threat Intelligence (CTI) in the context of Software Defined Networking (SDN). More specifically, we propose IntelFlow, an intelligence detection system for Software Defined Networking (SDN) that follows ...

We consider a distributed Software Defined Networking (SDN) architecture adopting a cluster of multiple controllers to improve network performance and reliability. Besides the Openflow control traffic exchanged between controllers and switches, we focus on the control traffic exchanged among the controllers in the cluster, needed to run coordination and consensus algorithms to keep the controll...

Software-defined networking (SDN) has emerged as a new paradigm of networking that enables evolvable and programmable networks allowing network operators, owners, vendors, and even third parties to innovate and create new capabilities at a faster pace. The SDN paradigm shows potential for all domains of use including the data center, cellular, service provider, enterprise, and home. In this pap...

Software-Defined Networking-based Mobile Networks (SDN-MNs) are considered the future of 5G mobile network architecture. With the evolving cyber-attack threat, security assessments need to be performed in the network management. Due to the distinctive features of SDN-MNs, such as their dynamic nature and complexity, traditional network security assessment methodologies cannot be applied directl...

Machine-to-machine (M2M) communications have attracted great attention from both academia and industry. In this paper, with recent advances in wireless network virtualization and software-defined networking (SDN), we propose a novel framework for M2M communications in software-defined cellular networks with wireless network virtualization. In the proposed framework, according to different funct...
