Software Defined Network (SDN) attract much attendance from research and industrial area; reason behind is the open interface, user controlled management and lower operating cost for data/flow handling rules that implements on software module rather than embedding in hardware with greatly improve performance. Network with the high security demanding higher in this generation. New service and products...
Digital Pulse Width Modulation (DPWM) is one of the most elementary parts in Digital Control Systems for the control of the power switch. Hence it has become an integral part of all System on Chips. It has also been broadly acknowledged as the control method in power converters. The principal focus of this paper is the design of FPGA based Digital controller for a DC-DC Buck convertor for SoC. The...
In this paper a two-layer linear Model Predictive Control strategy is proposed. The problem of establishing a consistency between the mathematical formulations of the two layers is analyzed. At the lower layer, a basic Model Predictive Control module computes the future control moves taking into account predictions on the manipulated and controlled variables. In the quadratic optimization problem...
The reliability of a system can be increased by redundancy. With redundancy, faults can be detected through comparison and failing components can be replaced. In order to avoid the verification of different implementations, the creation of redundant components from a single source is beneficial. In this paper, we propose a hardware/software (hw/sw) co-design approach for control applications that...
We consider the problem of finding efficient methods to update forwarding rules in Software Defined Networks (SDNs). While the original and updated set of rules might both be consistent, disseminating the rule updates is an inherently asynchronous process, resulting in potentially inconsistent states. We highlight the inherent trade-off between the strength of the consistency property and the dependencies...
For Internet service providers to efficiently use network resources, they need to conduct traffic engineering to dynamically control traffic routes to accommodate traffic with limited network resources. The performance of traffic engineering depends on the accuracy of traffic prediction. However, the volume of network traffic has been changing drastically in recent years due to the growth of various...
Today, the transition of traditional networking model to SDN-type architectures poses several major challenges. In typical SDN settings, the routers and switches frequently generate requests to the controller which ensures the proper and efficient operation of the network. Increased workload on the controller results in larger control plane response times, which, in turn, leads to a delayed response...
Control theory and SDN (Software Defined Networking) are key components for NFV (Network Function Virtualization) deployment. However little has been done to use a control-theoretic approach for SDN and NFV management. In this demo, we describe a use case for NFV management using control theory and SDN. We use the management architecture of RINA (a clean-slate Recursive InterNetwork Architecture)...
Software Defined Networking (SDN) is the new promise towards an easily configured and remotely controlled network. Based on Centralized control, SDN technology has proved its positive impact on the world of network communications from different aspects. Security in SDN, as in traditional networks, is an essential feature that every communication system should possess. In this paper, we propose an...
In this work we present the remote control of the tank level system. The physical system is controlled in real time using local or Internet network. The client could manage the remote experiment through a simple web browser via a graphical shared user interface. The study is based on the PID identification parameters according to Ziègler-Nichols methods. After the identification of the PID parameters...
Software defined networking promises network operators to dramatically simplify network management. It provides flexibility and innovation through network programmability. With SDN, network management moves from codifying functionality in terms of low-level device configuration to building software that facilitates network management and debugging[1]. SDN provides new techniques to solve long-standing...
Software Defined Networking (SDN) is an emerging technology that is replacing traditional networks in many advanced applications such as network virtualization and cloud computing. Recently, SDN has been proposed for wireless networks to add flexibility to incorporate exponentially increasing wireless traffic and to adapt network configurations on the fly, and it is known as Software Defined Wireless...
In recent years, there has been a trend towards changing the Internet paradigm from location-based to content-based. Based on the principle that networks should allow users to focus on data, rather than having a reference to a physical location where that data is, the adoption of new paradigms can be justified. Information-Centric Networking (ICN) is a new paradigm that gives a potential improvement...
The internet is vast and growing continuously. There is a need to control the characteristics and to provide security to the network. Software defined networking (SDN) is an approach where we divide the network into control and data plane. Using SDN and Hadoop in this paper we show a method to control characteristics and provide security to the network which is helpful in capacity planning and attack...
Software Defined Network abbreviated as SDN is a new paradigm which is transforming the existing network into a real time dynamic and programmable network. The logically centralized nature of SDN supports the emerging network architecture with many features such as centralized control of the network by decoupling the control plane and data plane thus enabling a global view of the network. It provides...
Network virtualization(NV) provides containers to separate the tasks but share hardware resources and thus leads to reduced cost, increased network service deployment and efficiency of network. This virtual network is separated from physical hardware and can be used for performing operations like creation and deletion. Software-Defined Networking (SDN) separates the control plane from the data-plane...
With the widespread use of distributed version control systems for software development, many software development projects are being shared and managed in a Web environment. This allows many developers, including project leaders and supporters, those who write important functions, those who resolve bugs and errors, and those who provide fundamental source code to relieve bottlenecks, to collaboratively...
Content Centric Networking (CCN) represents an important change in the current operation of the Internet, prioritizing content over the communication between end nodes. Routers play an essential role in CCN, since they receive the requests for a given content and provide content caching for the most popular ones. They have their own forwarding strategies and caching policies for the most popular contents...
Software Defined Networking (SDN) architecture promises to mitigate limitations of traditional networking architectures in order to satisfy today's complex networking needs. However, as all new networking architectures, SDN also presents several inevitable technical challenges to be addressed by researchers. Control plane scalability is one of the crucial issues deserving more attention from both...
In this paper, model reference adaptive control of fractional order system using ANFIS and CANFIS has been discussed.
