Learn how the basics of SS7 operations, how SS7 is the way 800 numbers work and how calls are processed in today's intelligent network Signal Transfer Points (STP's) and Signal Control Points (SCP's). This tutorial is open to all NetSci students and Guests.  See course details here.

The ability to use Linux is crucial to anyone in networking today.  So much of the network is Linux based - from switches to routers, servers and tools.  There has been a huge migration to Linux and this course is a great way to get started in Linux.  We have previewed a number of Linux courses that are free.  They say - you get what you pay for.  We agree.  That said, we found this one to be one of the best ones that is free. This is an All-In-One video.  Some people like this - some people like a step by step approach.  If you prefer the step by step approach, you can find that free course here.  That said, it is going to take you some time.  You can't learn this properly in less than an hour.  Plus we have added and will continue to add lab exercises so you can practice what you learn.

Netmiko started in late 2014.  Kirk Byers has been working on an open-source Python library that simplifies SSH management to network devices. The library is based on the Paramiko SSH library and is named Netmiko.  We have previewed a number of Netmiko courses that are free.  They say - you get what you pay for.  We agree.  That said, we found this one to be the best one that is free.

The ability to use Git has become very important in Networking today.  From version control of your own code, scripts or documents to acquiring software, tools, and updates, Git and Git Hub are essential tools.  We have previewed a number of Git courses that are free.  They say - you get what you pay for.  We agree.  That said, we found this one to be the best one that is free.

The ability to code in Python is crucial to anyone in networking today.  With tasks like network automation, and the move toward Linux in networking, this course is a great way to get started in Python in particular and coding in general.  We have previewed a number of Python courses that are free.  They say - you get what you pay for.  We agree.  That said, we found this one to be the best one that is free.  This course will give you a full introduction into all of the core concepts in python. Follow along with the videos and you'll be a python programmer in no time!

This reference/course describes what Ansible is and how it can be used for network/datacenter configuration/automation from templates.

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.
