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 considers the questions that planners and policy makers in open and distance learning need to address at any level of education.

Motivational and social aspects as interactions among teachers and students are essential for a successful educational process in an open distance learning (ODL) environment, and the goal of this book is to develop an interactive model to manage motivation between the participants of the learning process. The book deals with the important and topical problem of e-learning, closely connected with the use of modern information technologies in education. The focus is on developing an information management system for supporting the distance learning process in colleges and universities in the context of steadily expanding information technologies. On the basis of exiting standards (SCORM, etc.) as well as information systems and platforms (e.g., Moodle, etc.), the author proposes a coherent and original concept of modelling three ODL subprocesses: (1) an ontological model (how to represent the structure of didactic materials), (2) a motivation and collaboration model (how to motivate project process participants) and (3) a simulation model (how to realise the learning/project process). The proposed models constitute a theoretical formalization of a new situation in which a teacher and students are obligated to elaborate on didactic material repository content in accordance with the requirements of acquired competencies. A mathematical method based on game theory and simulation is suggested. The kind of educational system represented in the book can be used as a model of open distance learning aimed at active behaviour of students and teachers in not only the development of knowledge but also the acquiring of competencies.

This volume investigates the uptake of ‘open learning’ in South African Technical Vocational Education and Training (TVET) colleges and higher education institutions. Comprised of 16 studies focused on activities at a range of colleges and universities across the country, these chapters aim to promote a better understanding of open learning practices across the Post- School Education and Training (PSET) sector, including issues such as: recognition of prior learning, access for students with disabilities, work integrated learning, professional development, novel student funding mechanisms, leadership for open educational practices, institutional culture, student support, blended and online learning, flexible learning, online assessment, open educational resource development models and funding, and micro- credentials. This collection of peer-reviewed chapters contributes to understanding the ways in which South African PSET institutions and educators are interpreting ‘open learning’ as a means of advancing social justice. It includes a historical and contemporary understanding of the economic, cultural and political obstacles facing PSET, drawing on Nancy Fraser’s theory of social justice as ‘participatory parity’ to better understand the ways in which ‘open learning’ may address systemic social injustices in order to allow South African students and educators to thrive. This volume emerges from research conducted by the Cases on Open Learning (COOL) project, an initiative by the Department of Higher Education and Training in partnership with the Centre for Innovation in Learning and Teaching (CILT) at the University of Cape Town (UCT) in South Africa.
