COURSE DESCRIPTION

Learning Objectives:

Course Logistics

The course will cover SDN principles; OpenFlow; SDN controllers; network virtualisation; software-defined radio; SDN security; and SDN research topics. A detailed schedule can be found here. The students will prepare 4 programming assignments on which their grading will be based (there will be no final exam or midterm). In addition, there will be guest lectures on selected research topics from experts in the area.

What is SDN?

Computer networks have a control plane (tracking the topology, computing routes and updating forwarding tables etc.) and a data plane (forwarding, buffering, filtering, marking packets etc.). The interface between the control and the data plane is traditionally closed, within the internals of proprietary routers and switches. Software Defined Networking (SDN) is a new rapidly emerging computer networking paradigm that separates the control from the data plane and introduces an open interface between a centralized network controller and the data plane. By opening up the interface between the control and the data plane, it becomes easier to programmatically control networks and network innovation is accelerated. SDN has revolutionalized computer networking as it improves network manageability and enables new applications, like network virtualization, especially in data center networks. It has been listed by the 2009 MIT Technology Review in the top-10 emerging technologies and it is already adopted by many major players like Google, Cisco and Juniper.

Prerequisites: HY-335

Grading:

Students will be orally tested on the assignments. There are also 2 midterms during the semester. The final grade is calculated as follows:

Assignment guidelines:

The steps outlined above will result in copying your askN folder into the account used by the HY-436 course. Each student's submission is associated with his/her login ID, and is assigned a time-stamp using the system's clock. You may also consult these directions .
