blackboard1.jpgWelcome to the Online Network Science Courses area!  

The courses shown below are online, self paced, online courses.  

All you need is an Internet connection and a browser!

What this means is these courses combine on demand video learning with hands on lab exercises of various types.  

From quizzes, that test your learning and reinforce key learning points, to experiments, you can run either on your computer or within the GNS3 or mininet environments, practicing what you are learning is what we have always believed in.

[You can learn more about GNS3 and mininet in our Reference Library.]

  

A couple of key points:

Some of the classes are free.  To enroll in these, we encourage you to create a user here, although you can log in as a "Guest". You will see the following symbol for these courses:


Some of the classes are not free.  These classes require you to have a user account here.  

These classes will provide two enrollment options:

You can pay for the course securely using Paypal.   You do not need a Paypal account!  You can simply pay with a credit card at Paypal.  Or, if you have a Paypal account, you can pay with your account.  If a course uses this enrollment method you will see the Paypal symbol.

If your company or organization has provided you with an enrollment key, you can use the enrollment key to enroll in that course.  If a course uses this enrollment method, you will see the key symbol.

Understanding the basics of the rapidly evolving Telecommunications Networks is important to Service Provider new hires, technical and customer service employees.  This one day Telecom 101 course  explains and demystifies the terms used, and the technologies, functions and components that make up the complex world of the voice and data telecommunications networks.  So much has happened historically, the buzz words and three letter acronyms that the experienced take for granted can be overwhelming.  From Plain Old Telephone Service, to the Internet, to the regulatory environment, this course provides a complete survey and reference for the terms, the network equipment functions, and the components that make up the complex world of voice and data telecommunications.

This Wireshark 101 course is a fast start to using Wireshark for packet analysis.  Basic configuration and customization of capturing packets, displaying/filtering packets, and customizing the environment is covered.  Even if you have used Wireshark before, there are critical usage tips and methods that will change the way you use this tool

This course is an introduction to Data Networking principles and concepts.  From understanding the layered model of communications and how TCP/IP fits that model, to understanding how TCP/IP packets are forwarded through the network.  These basics are essential comprehension as to how the Internet and Ethernet technologies work together.

This course is an introduction to Ethernet principles and concepts.  From understanding the structure of Ethernet Frames, to understanding how Ethernet behaves (including protocols like ARP and Spanning Tree), this course provides a solid understanding of Ethernet fundamentals.  

This course provides the essential knowledge and skills in handling IPv4 Addressing.  Anyone working with the Internet has to understand the IPv4 Addressing schema, and the history of addressing changes that shape the way we use IPv4 in networks.  From Classful, to Classless, Subnetting and Supernetting, the IPv4 addressing schema can be complex, but in this course we will provide you the tools and skills to quickly conquer this technology so you can put it to use in your daily activities.

This course focuses on the functions that Routers perform in an Internet, and the protocols they use, such as RIP, OSPF and BGP, in the control plane to make Shortest Path First decisions and deliver packets to their intended destinations as quickly and efficiently as possible.  Understanding this process is critical in understanding how the Internet actually works.  

The 4G 101 Foundation course is focused on understanding 4G/LTE terminology and the Evolved Packet System (EPS) architecture. It will compare and contrast LTE with other broadband wireless technologies including 802.11n Wi-Fi and 802.16 WiMAX. This course will also provide an overview of the key features in LTE-Advanced and the emergence of fifth generation (5G) wireless networks.  See the course details here.

The 4G 201 Advanced course will provide a detailed description of how LTE achieves higher data rates. It will also discuss how voice and video over LTE (VoLTE) is enabled. The course will also discuss how roaming is supported between these LTE and other networks including WiFi. In addition it will describe the emerging standards that enable mobile service providers to offload data to Wi-Fi.  See the course details here.

ZigBee is a set of specifications that define how small low power devices communicate. It is a leading standard for the connectivity of wireless sensors, control and monitoring networks for home and industrial automation. Applications include controlling light switches, patient monitoring, smart energy, and traffic management systems.

ZigBee builds on the IEEE 802.15.4 Wireless Personal Area Network (WPAN) standard, adding network and application layers, as well as application objects and cluster libraries that allow vendors to customize their solution. This course takes a layered approach to explaining how ZigBee networks work. It starts with an explanation of the 802.15.4 layers. It then takes the student through the evolution of ZigBee network layer, covering ZigBee 2007, ZigBee PRO, and ZigBee IP.  See the course details here.

This is a free and open SDN course originally from Georgia Tech.  We have assembled the lectures of the course here for our Network Scientists and added our own quizzes and assignments.  This course introduces software defined networking, an emerging paradigm in computer networking that allows a logically centralized software program to control the behavior of an entire network.
