Мы завершаем курс на этой неделе, и нам очень повезло, как раз
вовремя, чтобы один из отцов SDN присоединился к нам, Ник Маккиун.
Ник действительно был очень вовлечен в сетевые
исследования даже до эры открытого потока SDN.
Ранее он работал с Cisco, он помогал в проектировании маршрутизатора GSR.
Он присоединился к Стэнфорду в 1995 году.
С тех пор он также основал пару других компаний,
одна из которых также была куплена Cisco в 2006 году.
Он основал в Стэнфорде программу создания чистых сетей, которая
в конечном итоге стала генезисом OpenFlow и движения SDN.

In this module, you will learn about the motivation and history behind the separation of the control and data plane, as well as the challenges and opportunities that this architectural paradigm offers.
Задачи обучения
Explain the difference between control and data plane.
Produce examples of functions provided by each plane.
Demonstrate the function of each plane.

In this lesson, you will gain experience with OpenFlow/SDN control, gain some exposure to different SDN controllers, learn about the tradeoffs of using different SDN controllers, and gain some experience of using SDN to customize control-plane behavior.
Задачи обучения
Summarize how an SDN controller can populate a switch's forwarding table.
Describe the benefit of using an SDN controller to control multiple switches in a single network.
Create a controller and basic switch environment.
Compare the design tradeoffs between some of the more commonly used SDN/OpenFlow controllers.
Set up controller in Mininet that can perform basic operations.

This module is relatively independent from some of the other modules, as programmable data planes involve new types of technology. Still, you should by now have a very good understanding of SDN-based control and virtualization. OpenFlow's design was somewhat of an accident of the hardware support that was available at the time. More recently, people are exploring how programmable hardware can help us design a control protocol with the benefit of being able to change the data plane.
Задачи обучения
Describe why programmable data planes are needed.
Discuss the limitations of OpenFlow and how programmable data planes can address some of these limitations.
Appreciate some of the design decisions associated with programmable data planes.
Compare the tradeoffs between hardware and software programmable data planes (i.e., flexibility vs. performance).

In this part of the course, you'll learn about programming languages and controllers that make this programmability possible. We will focus on one language in particular, Pyretic, which is from the Frenetic family of languages. We will also look at a runtime and northbound API called Resonance, which allows network programmers to write policies that respond to changing network conditions (e.g., security events, shifts in peak vs. off-peak time, traffic fluctuations or link failures).
Задачи обучения
Describe why SDNs need higher-level programming languages.
Distinguish between the applications and use cases of different SDN programming languages.
Implement simple network policies with SDN programming languages.
