    1.过去20年中可编程网络的发展可以分为几个阶段?每个阶段的贡献是什么?

    (1) active networks

      • introduced programmable functions in the network to enable greater to innovation;

      • Programmable functions in the network to lower the barrier to innovation;

      • Network virtualization, and the ability to demultiplex to software programs based on packet headers;;

      • The vision of a unified architecture for middlebox orchestration.

    (2) control and data plane separation

      • developed open interfaces between the control and data planes;

      • Logically centralized control using an open interface to the data plane;

      • Distributed state management;

    (3) the OpenFlow API and network operating systems

      • represented the first instance of widespread adoption of an open interface and developed ways to make control-data plane separation scalable and practical.

      • Generalizing network devices and functions

      • The vision of a network operating system

      • Distributed state management techniques
