How Networks Really Work

It’s pretty easy to find material explaining how to configure network devices. Internet is full of recipes and sample designs (not all of them good), but it’s hard to find information on how networking technologies really work and even harder to find out the reasons they were implemented the way they were.

In the meantime, vendors prove validity of RFC1925 Rule 11 on daily basis, and many customers blindly trust the shiny new technologies because they lack historical insight:

  • Did we try similar things in the past?
  • Did they work?
  • Why did they fail?
  • Has anything changed in the meantime that might make them better?

This webinar will help you:

  • Realize why networking matters even if you’re an application developer
  • Understand how networking technologies really work
  • Grasp why they were designed the way they were
  • Identify similarities between supposedly new ideas and past attempts

About the webinar

I am older than Ethernet. This brings back a lot of memories of the good old days of networking some good some bad. Pretty interesting to have all this put together as one whole picture of the evolution of Packet and character stream technology.
