Foundations of Modern Networking: SDN, NFV, QoE, IoT, and Cloud

Foundations of Modern Networking is a comprehensive and cohesive examination of modern networking technology and its applications, designed for today's professionals, managers, and students. Dr. William Stallings provides a clear and well-structured exploration of five key technologies reshaping networks: Software-Defined Networks (SDN), Network Functions Virtualization (NFV), Quality of Experience (QoE), the Internet of Things (IoT), and cloud-based services. Dr. Stallings assesses the current state of network ecosystems and the challenges they encounter, ranging from Big Data and mobility to security and complexity.

Subsequently, he delivers in-depth, self-contained coverage of each of these innovative technologies, elucidating their functioning, architectural aspects, and practical applications for addressing real-world problems. Additionally, Dr. Stallings dedicates an entire chapter to the analysis of emerging security concerns in modern networks. The book concludes with an up-to-date discussion on networking careers, including recent role changes and skill requirements.

The book encompasses the following topics:

1. Elements of the modern networking ecosystem: technologies, architecture, services, and applications.
2. Evolving demands of contemporary network environments.
3. SDN: fundamental concepts, rationale, applications, and standards spanning data, control, and application planes, along with key SDN technologies like OpenFlow and OpenDaylight.
4. Network functions virtualization: core concepts, technology, applications, and software-defined infrastructure.
5. Ensuring Quality of Experience (QoE) for customers, particularly with interactive video and multimedia network traffic.
6. Cloud networking: encompassing services, deployment models, architecture, and connections to SDN and NFV.
7. In-depth exploration of IoT and fog computing, covering essential components of IoT-enabled devices, model architectures, and practical implementations.
8. Strategies for securing SDN, NFV, cloud, and IoT environments.
9. Guidance on career preparation and continuous education for future networking roles.
