SDN : software defined networks = 软件定义网络(影印版)
发布日期:2014-07-16  浏览

[内容简介]

  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、权威指南,详细讲解了SDN的新兴定义、协议和标准。两位资深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。
