1. Welcome to Our Courses - An Introduction

Course Catalog

Welcome to the Online School of Network Sciences Course Catalog.

This catalog contains all the courses we offer, our faculty, and other important information.  Looking specifically at the courses in this catalog, we will provide the following details for each course:

  • Course Type/Length/Size - the options here are:
    • Online Only - meaning the course is a self-paced, video lecture and lab exercise based course
    • Web-Based Instructor Led - meaning that the course is taught over the web via tools like Webex, HP Rooms, or similar web meeting/training programs
    • Classroom-Based Instructor Led - meaning the more traditional model of training where our instructors teach in a classroom environment, though we will use the online school for distribution of materials and lab exercises.
  • Course Description
  • Course Objectives
  • Target Audience
  • Course Pre-Requisites
  • Course Materials
  • Related Content
  • Course Outline

The Catalog groups the courses by our Course Categories.

To explore the courses, you will find a navigation block/list on the right ----------------->

Simply click on any course in the list to view the details of that course.

You will find certain terms highlighted (such and TCP or MPLS) throughout the catalog.  The reason we do this is these acronyms can be confusing to many and the terms are linked to our Glossary.  Just hover and click on the term and we will define the term for you!

2. Online Network Science Courses

The courses in this category are self paced, online learning courses.  

What this means is they 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.

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.

The bottom line, is these are great courses that allow the ultimate in flexibility for the learner to learn at their own pace, anywhere they can connect to the Internet. 

They are less expensive as the Instructor is not physically present, however we provide a forum in each course that allows the student to interact and ask questions that the instructor can reply to.  In some courses we even offer one-on-one meeting access, all done within the online school and requiring no special software for the student.

2.8. Software Defined Networking - Free and Open to all

Want to understand SDN as well as see it in action?  This course can be found on the Internet and the video lectures have been released as open to everyone!  We have reassembled and added our own assignments and quizzes to the course here.  

The course leverages our favorite SDN tool: mininet!  You will be installing and configuring mininet as an assignment in this course!

In this course, you will learn about software defined networking and how it is changing the way communications networks are managed, maintained, and secured.  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.  

Separating a network's control logic from the underlying physical routers and switches that forward traffic allows network operators to write high-level control programs that specify the behavior of an entire network, in contrast to conventional networks, whereby network operators must codify functionality in terms of low-level device configuration.  

Logically centralized network control makes it possible for operators to specify more complex tasks that involve integrating many disjoint network functions (e.g., security, resource control, prioritization) into a single control framework, allowing network operators to create more sophisticated policies, and making network configurations easier to configure, manage, troubleshoot, and debug.

3. Technology Briefings and Overviews

The courses in this area are special, concatenated classes intended as higher level overviews.  

They are intended to cover breadth and not depth in a short time period.

These classes are attractive to those students wanting a more brief coverage of a given subject where concepts and terms need to be defined, but not necessarily operational details. 

We usually teach these courses as online web based delivery - instructor led training using tools like Webex, HP Rooms, or other similar online meeting/training tools.

We try to keep these courses to around 4 hours of learning, and we provide many references and of course student guide PDF's to all attendees.

4. Wireless Technology Courses

The world of wireless is a broad set of technologies and solutions.

As with TCP/IP itself, many people assume Wi-FI and WLAN is simple plug and play technology that does no require technical understanding of it's operation, just general experience will do.

Nothing could be further from the truth.

With the prevalence of wireless in the home, small business, and the emerging IoT, there is so much to learn and to understand.  WLAN issues today represent 60% or more of truck rolls for service providers and we find the level of knowledge and understanding is minimal - on the job training.  What is you could do better?  How would that impact customer satisfaction?

It isn't just service providers.  Almost all new technologies must be wireless.  So developing solid solutions with a deep technical understanding of the requirements and protocols is vital for engineers.

We offer courses in both areas.  We have grouped our courses into the following wireless technologies:

  • Wi-Fi and WLAN - these are the 802.11 based technologies
  • Cellular - 4G and 5G
  • Enabling the Internet of Things - technologies that support wireless IoT capabilities

These courses are offered primarily as Instructor Led classes, either as Web based delivery using Webex or HP Rooms or similar tools, or On Site instructor led classes.

5. Wireshark Courses

Welcome to our Wireshark Courses!

We have been using the Wireshark packet dissector and analyzer tool since it was originally released as Ethereal.  

This is perhaps one of the most important tools that anyone working in broadband Internet, computer, voice, video and data networking can learn to use. 

There are several Wireshark courses offered, with a differing focus for each one.  Is your focus on Data Center, Wireless, or Voice?  Check out the different classes below.

These classes are offered as Instructor Led classes either online or in person.

6. The TCP/IP Protocols

The Internet.

What makes this world of packet switching are the TCP/IP protocols.

The good news is it works and the protocols are open! 

The bad news is it isn't just one thing or just one protocol.  There are no less than 8 versions of TCP.  There are 2 versions of IP (IPv4 and IPv6).

Since it works (for the most part) most people assume there is little to learn here...just plug and play.  Network Scientists know very differently.

The courses listed here focus on these protocols, and they provide hands-on level knowledge and understanding.

7. MPLS Web Based Delivery Courses

In the late 1990's and early 2000's, Multiprotocol Label Switching (MPLS) revolutionized how service providers and enterprise networks transported IPv4 and IPv6 packets in the network.

As time moved on, this technology was then leveraged to transport a number of other different protocols like Frame Relay and Ethernet, the later paving the way for what we now know as Metro Ethernet.

The following MPLS courses are delivered via Instructor Led Web Based Delivery only.

The classes are in a series: MPLS 101, 201, 301, 401, and 501.  

We suggest they are taken in that serial fashion, although it is not required.  

Each course has a pre-reading assignment in preparation for the Web Delivery portion of the class.
