Like sysadmins before them, network engineers are finding that they cannot do their work manually anymore. As the field faces new protocols, technologies, delivery models, and a pressing need for businesses to be more agile and flexible, network automation is becoming essential. This practical guide shows network engineers how to use a range of technologies and tools—including Linux, Python, JSON, and XML—to automate their systems through code. Network programming and automation will help you simplify tasks involved in configuring, managing, and operating network equipment, topologies, services, and connectivity. Through the course of the book, you’ll learn the basic skills and tools you need to make this critical transition. This book covers: Python programming basics: data types, conditionals, loops, functions, classes, and modules Linux fundamentals to provide the foundation you need on your network automation journey Data formats and models: JSON, XML, YAML, and YANG for networking Jinja templating and its applicability for creating network device configurations The role of application programming interfaces (APIs) in network automation Source control with Git to manage code changes during the automation process How Ansible, Salt, and StackStorm open source automation tools can be used to automate network devices Key tools and technologies required for a Continuous Integration (CI) pipeline in network operations

Today, networks must evolve and scale faster than ever. You can’t manage everything by hand anymore: You need to automate relentlessly. YANG, along with the NETCONF, RESTCONF, or gRPC/gNMI protocols, is the most practical solution, but most implementers have had to learn by trial and error. Now, Network Programmability with YANG gives you complete and reliable guidance for unlocking the full power of network automation using model-driven APIs and protocols. Authored by three YANG pioneers, this plain-spoken book guides you through successfully applying software practices based on YANG data models. The authors focus on the network operations layer, emphasizing model-driven APIs, and underlying transports. Whether you’re a network operator, DevOps engineer, software developer, orchestration engineer, NMS/OSS architect, service engineer, or manager, this guide can help you dramatically improve value, agility, and manageability throughout your network. Discover the value of implementing YANG and Data Model-Driven Management in your network Explore the layers and components of a complete working solution Build a business case where value increases as your solution grows Drill down into transport protocols: NETCONF, RESTCONF, and gNMI/gRPC See how telemetry can establish a valuable automated feedback loop Find data models you can build on, and evaluate models with similar functionality Understand models, metadata, and tools from several viewpoints: architect, operator, module author, and application developer Walk through a complete automation journey: business case, service model, service implementation, device integration, and operation Leverage the authors’ experience to design successful YANG models and avoid pitfalls

The entire networking industry is being pressured to automate to scale and move faster. In modern networks, you just can't manage everything by hand anymore. You need to automate relentlessly, and the most practical way to do so is with YANG and NETCONF. But existing documentation on these technologies has been poor, jargon-filled, or non-existent, so most implementers have been forced to learn by trial and error. Now, Network Programmability with YANG gives them comprehensive and reliable guidance for unlocking the power of network automation using model-driven APIs and protocols. Written by three leaders of the YANG development effort, this plain-spoken book guides networking professionals in successfully applying software practices based on YANG data models. The authors focus on the network operations layer, emphasizing model-driven APIs and underlying transports. Using their information and insights, network professionals can transform the way they manage large networks.

The general trend of modern network devices towards greater intelligence and programmability is accelerating the development of systems that are increasingly autonomous and to a certain degree self-managing. Examples range from router scripting environments to fully programmable server blades. This has opened up a new field of computer science research, reflected in this new volume. This selection of contributions to the first ever international workshop on network-embedded management applications (NEMA) features six papers selected from submissions to the workshop, held in October 2010 at Niagara Falls, Canada. They represent a wide cross-section of the current work in this vital field of inquiry. Covering a diversity of perspectives, the volume’s dual structure first of all examines the ‘enablers’ for NEMAs—the platforms, frameworks, and development environments which facilitate the evolution of network-embedded management and applications. The second section of the book covers network-embedded applications that might both empower and benefit from such enabling platforms. These papers cover topics ranging from deciding where to best place management control functions inside a network to a discussion of how multi-core hardware processors can be leveraged for traffic filtering applications. The section concludes with an analysis of a delay-tolerant network application in the context of the ‘One Laptop per Child’ program. There is a growing recognition that it is vital to make network operation and administration as easy as possible to contain operational expenses and cope with ever shorter control cycles. This volume provides researchers in the field with the very latest in current thinking.

Cloud Computing: Architecture and Design Fundamentals is a technical guide for network, systems and security engineers. The technical skills required are changing rapidly with SDN applications that enable orchestration and automation of applications and services. The physical and virtual appliances are now programmable through open APIs and controllers. The network is globally managed across public and private clouds. The proliferation of applications and demand for cloud services such as workload mobility is causing the traffic shift from enterprise to cloud. The virtualization of servers and network devices is causing an overlap of management domains for network and systems groups. The network devices and applications now reside at cloud servers as virtual machines. Dynamic context-based security is required to support the internet-based model for connecting cloud endpoints. The server-centric paradigm shift is redefining how network capacity is managed as well. Real-time analysis of operational state and programmability is enabling the automation of network services.
