内容简介

SDN网络能够在网络应用层和底层的网络基础设施之间实现快速的双向通信,从而提供更丰富、更令人满意的用户体验。在本书中,来自Juniper公司的两位资深工程师讲解了SND网络的定义、协议、标准和用户案例。通过本书的学习,读者将知道如何来构建计算机网络,从而使企业和服务提供商使用软件来实现双向的通信。本书适合网络设计师、网络运维人员,以及当前正在从事SDN技术研究的高校/科研机构的人员阅读。

  软件定义网络(SDN)是由软件定义、驱动,并且可编程的网络。《软件定义网络(影印版)》是SDN的全面指南,详细讲解了SDN的新兴定义、协议和标准。两位**的工程师在书中为读者讲解了构建软件定义网络(即使用软件在应用和底层网络设施之间进行双向通信)所必需的知识。

  《软件定义网络(影印版)》共分为13章,分别讲解了OpenFlow模型和集中网络控制的当前进展;分布式控制和集中控制、包括数据平面生成;商业控制器和开源控制器的结构和功能;网络可编程性的现有技术;以桌面为中心的模型到高度分布式模型在内的现代数据中心;网络功能虚拟化和服务链的连接实例;构建和维护SDN网络拓扑;用于控制器、应用和生态系统的理想SDN框架等知识。

  《软件定义网络(影印版)》不依赖于具体厂商的产品,除了介绍与带宽调度和操作、输入流量、触发行为等相关的SDN用例外,还展示了一些与大数据、数据中心覆盖和网络功能虚拟化等相关的有趣用例。

  《软件定义网络(影印版)》适合网络设计/运维人员、从事SDN研究的科研院所、高效的先关从业人员阅读。
