Networks today rely on middleboxes to provide critical performance, security, and policy compliance functions. Today, however, achieving these benefits and ensuring that the traffic traverses the desired sequence of middleboxes requires significant manual effort and operator expertise. In this respect, Software-defined Networking (SDN) offers a promising alternative. However, middleboxes introd...

While the novelty of Software-Defined Networking (SDN) — the separation of network control and data planes — is appealing and simple enough to foster massive vendor support, the resulting impact on the security of communication networks infrastructures and their management may be tremendous. The paradigm change affects the entire networking architecture. It involves new IP-based management comm...

Software-Defined Networking (SDN) is a new networking paradigm that grants a controller and its applications an omnipotent power to have holistic network visibility and flexible network programmability, thus enabling new innovations in network protocols and applications. One of the core advantages of SDN is its logically centralized control plane to provide the entire network visibility, on whi...

The brain shows various sex differences in its structures. Various mammalian species exhibit sex differences in the sexually dimorphic nucleus of the preoptic area (SDN-POA) and parts of the extended amygdala such as the principal nucleus of the bed nucleus of the stria terminalis (BNSTpr) and posterodorsal part of the medial amygdala (MePD). The SDN-POA and BNSTpr are male-biased sexually dimo...

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 ...

Software-Defined Networking (SDN) is a novel architectural model for cloud network infrastructure, improving resource utilization, scalability and administration. SDN deployments increasingly rely on virtual switches executing on commodity operating systems with large code bases, which are prime targets for adversaries attacking the network infrastructure. We describe and implement TruSDN, a fr...

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...

Software Defined Networking (SDN) is a current research trend that follows the ideology of physical separation of the control and data plane of the forwarding devices. SDN mainly advocates with two types of devices: (1) Controllers, that implement the control plane and (2) Switches, that perform the data plane operations. OpenFlow protocol (OFP) is the current standard through which controllers...
