[Packt Publishing] 软件定义网络 基于OpenFlow的SDN技术揭秘 第2版 (英文版)

Software-Defined Networking with OpenFlow Second Edition Copyright © 2017 Packt Publishing What this book covers Chapter 1, Software-Defined Networks, introduces you to the foundational topics that need to be covered before a deep dive into SDN and OpenFlow. Chapter 2, Introducing OpenFlow, introduces OpenFlow, its role in the SDN ecosystem, and how it works in a computer network. This chapter shapes the required knowledge prior to the actual setup of an experimental environment. The notion of flow forwarding, OpenFlow functions, what OpenFlow tables can do, and features and limitations of OpenFlow have revisited again in this chapter. Chapter 3, Implementing the OpenFlow Switch, covers the available implementations of OpenFlow switches, including hardware and software implementations. Chapter 4, The OpenFlow Controllers, covers the role of OpenFlow controllers as a control entity for OpenFlow switches and the provided API (that is, northbound interface) for the development of OpenFlow-based network applications (Net Apps). Chapter 5, Setting Up the Environment, introduces the options for OpenFlowswitches and controllers. It also covers the environment for Net Appdevelopment. This Chapter focuses on the installation of virtual machines(VMs) and tools (for example, Mininet and Wireshark), which will be used inthe next Chapters for Net App development. Chapter 6, Net App Development, covers developing sample networkapplications (for example, learning switch, firewall, and DHCP spoofing) toshow how OpenFlow provides the common ground for Net Appdevelopment. Chapter 7, Getting a Network Slice, covers network slicing using OpenFlowand FlowVisor. A setup will be planned and the Chapter will show how toconfigure and use a slice of the network using FlowVisor. Chapter 8, OpenFlow in Cloud Computing, focuses on the role of OpenFlow incloud computing and, in particular, the installation and configuration ofOpenStack's Neutron. Neutron is an incubated OpenStack project thatprovides network connectivity as a service (NaaS) between interface devices(for example, vNICs or virtual network interface cards), which are managedby other OpenStack services. Chapter 9, Open Source Resources, explains and gives pointers to theimportant open source projects that network engineers and/or administratorscan utilize in their production environment. These projects range fromcontrollers, virtualization tools, and orchestration tools to simulation andtesting utilities. Chapter 10, SDN Future, provides more insight into innovations expected to beintroduced into SDN and OpenFlow.
