Software Defined Networking and Network Function Virtualization

Learn how to provision network resources with greater flexibility using SDN and NFV.

GK# 4463

Course Overview

TOP

In this course, you will learn about software-defined networking (SDN) architecture and the essential protocols related to SDN implementations. This course thoroughly explains what SDN is, how it works, and then does a deep dive into the SDN protocols themselves. SDN can manage and control physical network elements as well as Network Function Virtualization (NFV), allowing network professionals to deploy and maintain a clean integration between cloud environments and the physical network itself.

We are often asked what the network looks like when it enters the cloud. This is why the study of NFV is a natural progression, so we combined SDN and NFV in one course. This course will clarify what happens at the cloud boundary and then look into the virtual network within the cloud. If you are a networking professional and you look at what is going on inside the cloud, you’ll realize you can take those concepts and implement them outside the cloud. The networking control layer will change radically with SDN, and we’ll show that the change is both amazing and powerful.

In this course, you will build, configure, and deploy the most popular network functions, routing, bridging, and OpenFlow switches along with requisite protocols. You’ll integrate the components with an emulated physical environment and perform verification testing. The cloud environment will be represented with a deep dive into OpenStack Neutron and Neutron-compute.
