Key FeaturesNavigate through the complexities of delivering modern networking services with practical techniques and solutionsBuild robust software defined networks and solve real-world problems involving challenges with next generation networksDiscover the best practices used by top industry professionals for network-related architecture, services, and applications and secure your networksBook DescriptionAs IT infrastructures become more software-defined, networking operations tend to be more automated with falling levels of manual configuration at the hardware level. Building Modern Networks will brush up your knowledge on the modern networking concepts and help you apply them to your software-defined infrastructure.In this book youll gain the knowledge necessary to evaluate, choose, and deploy a next generation network design. We will cover open and closed network operating systems (NOS) along with the protocols used to control them such as OpenFlow, Thrift, Opflex, and REST. You will also learn about traffic engineering and security concepts for NGNs. You will also find out how to fine-tune your network using QoS and QoE.By the end of the book, youll be well versed in simplifying the way you design, build, operate, and troubleshoot your network.What you will learnUnderstand Traditional Network Challenges to match modern applications requirementsFind out all about Next Generation Networks (NGN)Explore the different APIs used to control NGN devicesUnderstand the different software controllers available to manage NGN hardwareDesign a next generation networkAbout the AuthorSteven Noble has been working on computer networks for over 25 years.
