Network Course: IP Networks, Routers and Addresses

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

This e-learning course can be completed as an individual course, or as part of CTNS, the Certified Telecommunications Network Specialist certification package, which includes eight online courses covering Broadband, Wireless, PSTN, Voice over IP, Ethernet, OSI Layers, IP networks, and MPLS networks offered by Teracom Training Institute, and certification through the Telecommunications Certification Organization, TCO.

This course is also included in the CTA, Certified Telecommunications Analyst certification package, from Teracom.

Course Overview

This course covers OSI model Layer 3: the network layer, and so could be called "Layer 3". In particular it covers IP packet networks.

Packet networks embody two main concepts: packet switching and bandwidth on demand.

First, we recap channelized TDM with its limitations, then we explain statistical TDM which is bandwidth on demand.

Next, we explain how networks are implemented by routers using packet switching, which is relaying the packets between circuits, and how routers serve as a point of control to implement network security. We introduce the term Customer Edge, and explain the content and basic structure of a routing table.

Then we cover the many facets of IP addressing which are needed to perform packet switching: IPv4 address classes, static vs. dynamic addresses, dotted decimal notation, public vs. private addresses, DHCP, Network Address Translation, and end with an overview of IPv6 address allocation and assignment.
