How Networks Really Work

Overall rating: 5.00 Instructor: 5.00 Materials: 5.00 more …

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

Contents

The webinar currently covers these topics:

  • Fallacies of Distributed Computing
  • Why networking matters and why should every IT professional be interested in networking fundamentals
  • Overview of networking challenges
  • The importance of layered structure of a networking stack

The upcoming live sessions will address:

  • Addressing throughout the networking stack
  • Getting across the network (aka routing)
  • Transmitting bits and messages (from asynchronous transport and clock recovery to escaping, zero-insertion and quoting)
  • Layer-2 line disciplines
  • Cell-mode versus packet-mode transport
  • Connection-oriented versus connectionless transport
  • Virtual circuits versus hop-by-hop forwarding
  • The intractability of QoS
  • Congestion detection
  • In-band versus out-of-band signaling
  • Message- versus stream-oriented transport protocols
  • A day in a life of a web session

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.

It's one of the best technical resources for people who want to improve themselves professionally.

There's a wealth of knowledge on this site and this webinar only scratches the surface.

As always another webinar of great value for networking engineers.

I almost always play the recordings at 1.5X their original speed.

About the materials

It's fascinating to learn about the history why various standards got put in place that ignored the end to end principle.
