Software Defined Networks are intended to be less complex, more flexible, and free of vendor-lock-ins. Therefore the Software Defined Networking (SDN) instantiation OpenFlow has been designed according to these properties. The efforts are expected to result in lower expenditure and operational costs. To reach these objectives, mechanisms of classical networks that provide established functional...

Adoption of Software Defined Networking (SDN) remains largely confined to data center networks, where network architects frequently have the luxury of designing and deploying within a tightly controlled greenfield environment. In comparison, adoption of SDN technologies within existing ISP and enterprise networks depends on the network operator’s ability to evaluate SDN’s impact and define a tr...

Software Defined Network (SDN) has shown substantial benefits over the legacy network and fueled the implementation of a variety of innovative and intelligent applications on SDN Controller. However, these applications put the performance of SDN controller under question; since most of these applications excessively demand computing resources of SDN controller resulting in increased flow proces...

The sexually dimorphic nucleus of the preoptic area (SDN-POA) has received increased attention due to its apparent sensitivity to estrogen-like compounds found in food and food containers. The mechanisms that regulate SDN-POA volume remain unclear as is the extent of postweaning development of the SDN-POA. Here we demonstrate that the female Sprague-Dawley SDN-POA volume increased from weaning ...

This work is concerned with the integration of the two networking paradigms of ICN and SDN in order to provide an enhanced evolutionary path from today’s IP networks towards ICN. We introduce a scheme that allows for the operation of SDN based infrastructure, which provides network-wide ICN awareness. Further, an advanced approach, which allows for the forking of ICN packets throughout the SDN ...

Software defined networking (SDN) has established a new method for creating and administering networks, but has also changed the attack surface that is presented by networks. SDN provides several features that allow for easy mitigation of certain types of attacks, such as DoS, and allows for mitigation of other attacks with more work. However, SDN also introduces new vulnerabilities that are no...

Background: Few studies have compared superficial and deep dry needling techniques in treatment of trigger points in patients with Myofascial Pain Syndrome (MPS).  Objectives: To compare the effects of Superficial Dry Needling (SDN) and Deep Dry Needling (DDN) on Range of Motion (ROM) and functional ability in subjects with upper trapezius MPS. Materials & Methods: This is a quasi-experimenta...

High throughput access to large data structures for lookup and classification have made Ternary Content Addressable Memory (TCAM) indispensable in today’s network switching devices. TCAMs offer single cycle lookup operation but at the expense of notoriously high power dissipation. While there is no suitable alternative to TCAM for maintaining line rate lookup, high power dissipation of TCAM hav...

We explain the notion of software-defined networking (SDN), whose southbound interface may be implemented by the OpenFlow protocol. We describe the operation of OpenFlow and summarize the features of specification versions 1.0–1.4. We give an overview of existing SDN-based applications grouped by topic areas. Finally, we point out architectural design choices for SDN using OpenFlow and discuss ...
