  2. brief • 背景介绍:SDN和Openflow. • Introduction • Result

  3. 背景介绍 • 传统的互联网模型 ---------暴露的缺点:功能的不断增加导致路由器和交换机等交换设备越来越臃肿而且性能提升的空间越来越小。 ----------计算机领域日新月异的发展给予的启发以及关于网络的新的思想。 • Openflow • 什么是openflow和SDN:1.新型网络创新架构2.分离网络设备控制面和数据面 • Openflow设备有什么特点:4点。 • Openflow网络组成。

  4. Openflow网络组成

  5. Openflow交换机

  6. introduction • 本文的研究意义:openflow版本1.1和1.2仅仅提供初级的可靠性能。(比如快速进行热备份切换),但是并不支持快速有效的通信恢复和流保护的能力。 • openflow-based protection mechanism 分为以下两个: • Installation of required working and backup entries • Renewal mechanism for backup entries
