Familiarity with the day-to-day operations of computer networks is expected What You Will Learn Transition from legacy networking to software-defined networking Learn how SDN controllers work and manage a network using southbound and northbound APIs Learn how to deploy the OpenDayLight SDN controller and integrate it with virtual switches Understand the basic design and operation of the OpenDaylight platform Build simple MD-SAL OpenDaylight applications Build applications on top of OpenDayLight to trigger network changes based on different events Integrate OpenStack with OpenDayLight to build a fully managed network Learn how to build a software-defined datacenter using NFV and service-chaining technologies In Detail OpenDaylight is an open source, software-defined network controller based on standard protocols. It aims to accelerate the adoption of Software-Defined Networking (SDN) and create a solid foundation for Network Functions Virtualization (NFV). SDN is a vast subject; many network engineers find it difficult to get started with using and operating different SDN platforms. This book will give you a practical bridge from SDN theory to the practical, real-world use of SDN in datacenters and by cloud providers. The book will help you understand the features and use cases for SDN, NFV, and OpenDaylight. NFV uses virtualization concepts and techniques to create virtual classes for node functions. Used together, SDN and NFV can elevate the standards of your network architecture; generic hardware-saving costs and the advanced and abstracted software will give you the freedom to evolve your network in the future without having to invest more in costly equipment. By the end of this book, you will have learned how to design and deploy OpenDaylight networks and integrate them with physical network switches. You will also have mastered basic network programming over the SDN fabric. Style and approach This is a step-by-step tutorial aimed at getting you up-to-speed with OpenDayLight and ready to adopt it for your SDN (Software-Defined Networking) and NFV (Network Functions Virtualization) ecosystem.

Foundations of Modern Networking is a comprehensive, unified survey of modern networking technology and applications for today’s professionals, managers, and students. Dr. William Stallings offers clear and well-organized coverage of five key technologies that are transforming networks: Software-Defined Networks (SDN), Network Functions Virtualization (NFV), Quality of Experience (QoE), the Internet of Things (IoT), and cloudbased services. Dr. Stallings reviews current network ecosystems and the challenges they face–from Big Data and mobility to security and complexity. Next, he offers complete, self-contained coverage of each new set of technologies: how they work, how they are architected, and how they can be applied to solve real problems. Dr. Stallings presents a chapter-length analysis of emerging security issues in modern networks. He concludes with an up-to date discussion of networking careers, including important recent changes in roles and skill requirements. Coverage: Elements of the modern networking ecosystem: technologies, architecture, services, and applications Evolving requirements of current network environments SDN: concepts, rationale, applications, and standards across data, control, and application planes OpenFlow, OpenDaylight, and other key SDN technologies Network functions virtualization: concepts, technology, applications, and software defined infrastructure Ensuring customer Quality of Experience (QoE) with interactive video and multimedia network traffic Cloud networking: services, deployment models, architecture, and linkages to SDN and NFV IoT and fog computing in depth: key components of IoT-enabled devices, model architectures, and example implementations Securing SDN, NFV, cloud, and IoT environments Career preparation and ongoing education for tomorrow’s networking careers Key Features: Strong coverage of unifying principles and practical techniques More than a hundred figures that clarify key concepts Web support at williamstallings.com/Network/ QR codes throughout, linking to the website and other resources Keyword/acronym lists, recommended readings, and glossary Margin note definitions of key words throughout the text

This book examines the state of the Open and Distance Learning (ODL)-based secondary education in India. ODL-based education has been a key resource for children in India who can neither cope with nor avail of regular schooling opportunities due to economic, health and disability, or other constraints. The volume uses large-scale empirical data collected from various Indian states and a sensitive theoretical framework to study the equity, efficiency, and effectiveness of the National Institute of Open Schooling (NIOS) and the State Open School (SOS). Highlighting the roadblocks and barriers in terms of its reach, inclusion, and delivery, particularly to the marginalised, this book explores whether ODL has a potential of being a sustainable and effective option at the secondary and senior secondary level in India. Thus, it seeks to generate policy discourse around delivery mechanisms and effectiveness of ODL in developing countries. First of its kind, this comprehensive volume will be useful for scholars and researchers of education, education policy, public policy, and political studies.

Access to higher education in South Africa poses a number of challenges. First, South Africa is said to be one of the most unequal societies in the world, with an estimated Gini coefficient that ranges between 0.63 and 0.69 (Human Sciences Research Council, 2014; Statistics South Africa, 2014). The wealth gap between the countrys rich and the poorest of the poor is both growing and getting worse. Second, UNISA is an open distance learning (ODL) institution that seeks to intervene and manage the above challenges by offering access to higher education opportunities to millions of South Africans, the majority of whom are descendants of sections of society that were denied opportunities to access higher education by a myriad of institutionalised apartheid policies and legislation which were racist and discriminative. With these concerns in mind, the author compiled Open Distance Learning (ODL) Through the Philosophy of Ubuntu, which is a sequel to the authors previous publication, Open Distance Learning (ODL) in South Africa (Nova Publishers: New Nork, 2015); it explores the potential for the philosophy of Ubuntu to meaningfully shape UNISAs ability to deliver its ODL mode of teaching and learning. The philosophy of Ubuntu, which is also known as humaneness and/or human dignity, is an African worldview or normative concept that encapsulates moral values and principles such as kindness, generosity, compassion, benevolence, respect for persons, care and concern for others, as well as human dignity. The book draws on the philosophy of Ubuntu as a guiding conceptual framework to explore ways in which UNISAs vision of an African university in the service of humanity might be meaningfully driven and realised. This collection of fourteen chapters that constitute the book grapples with a wide range of critical questions such as: How might embracing the philosophy of Ubuntu impact UNISAs ability to meaningfully deliver a humane, open distance education to its students in South Africa, on the African continent, and on a global scale? How, for instance, would grounding UNISAs curricular offerings in the philosophy of Ubuntu turn the university into a uniquely African ODL institution? How would embracing the values and principles of Ubuntu shape UNISAs inclusive focus, research and innovative conceptual framework and impertaives, ODL teaching and learning, assessment and quality assurance, communication and public relations profile, among others? Finally, Open Distance Learning (ODL) Through the Philosophy of Ubuntu explores the plausibility of a radical change of mindset from business as usual to business unusual by re-imagining and recasting UNISAs ODL mission through the values and principles of the philosophy of Ubuntu. The book is the second offering of the planned trilogy of books on ODL in Southern Africa. The final volume, Assuring Institutional Quality in Open Distance Learning (ODL) in the Developing Contexts will complete this thought process on ODL.
