2212 The OSI Layers and Protocol Stacks   $49
 add to cart

This course establishes a framework for all of the discussions in subsequent lessons and courses: the OSI 7-Layer Reference Model, which identifies and divides the functions to be performed into groups called layers. This framework is required to sort out the many functions that need to be performed, and to be able to discuss separate issues separately.

You'll learn what a layer is, the purpose of each layer, see examples of protocols used to implement each layer, and learn how a protocol stack really works with the famous "FedEx Analogy" presented as an embedded video by our top instructor, Eric Coll.

Based on Teracom’s famous Course 101, tuned and refined over the course of 20 years of instructor-led training, we'll cut through the jargon to demystify layers, explaining the jargon and buzzwords, and most importantly, the underlying ideas, and how it all works together... in plain English.

2213 IP Networks, Routers and Addresses   $49
 add to cart

IP Networks, Routers and Addresses is a comprehensive course on IP networking fundamentals: IP packets, IP addressing and IP routers.

First, we'll understand packet networks and their advantages. Then we'll see how routers implement the network with packet-switching, that is, relaying packets from one circuit to another, and how routers are a point of control for network security. We'll introduce the term Customer Edge (CE), and understand the basic structure and content of a routing table.

Then we'll cover the many aspects of IP addressing – needed for the packet switching: IPv4 address classes, dotted decimal notation, static vs. dynamic addresses, DHCP, public vs. private addresses, Network Address Translation, and finish with an overview of IPv6 overview and IPv6 address allocation and assignment.
