Network Architecture In Practice
11-13, 11:00–15:00 (Europe/Berlin), Workshop 2
Language: English

In network engineering there are a lot of rules and best practices, some written and some not. In this workshop we condense the most important knowledge we have accumulated over many years of running different service provider networks.

We'll take a look at fundamental architecture decisions, traffic engineering and routing security for data and control plane.

There will be lots of real world config examples and plenty of time for questions and discussion.

Who is this for?

It is intended for people who (want to) run small to medium sized ISP networks. A basic understanding of routing concepts is going to be helpful. If you've configured a bgp session before, this workshop is for you.
