內容簡介

軟件定義網絡(SDN)是由軟件定義、驅動,並且可編程的網絡。《軟件定義網絡(影印版)》是SDN的全面、權威指南,詳細講解了SDN的新興定義、協議和標准。兩位資深的工程師在書中為讀者講解了構建軟件定義網絡(即使用軟件在應用和底層網絡設施之間進行雙向通信)所必需的知識。
  
《軟件定義網絡(影印版)》共分為13章,分別講解了OpenFlow模型和集中網絡控制的當前進展;分布式控制和集中控制、包括數據平面生成;商業控制器和開源控制器的結構和功能;網絡可編程性的現有技術;以桌面為中心的模型到高度分布式模型在內的現代數據中心;網絡功能虛擬化和服務鏈的連接實例;構建和維護SDN網絡拓撲;用於控制器、應用和生態系統的理想SDN框架等知識。
  
《軟件定義網絡(影印版)》不依賴於具體廠商的產品,除了介紹與帶寬調度和操作、輸入流量、觸發行為等相關的SDN用例外,還展示了一些與大數據、數據中心覆蓋和網絡功能虛擬化等相關的有趣用例。
