Vincentz Petzholtz

My name is Vincentz Petzholtz and I am working in the Network Industry since 2006. I always have been a Network Engineer and Architect through different positions and companies (Interoute/GTT/SysEleven/ Main area’s of expertise have been BGP (Routing, Policies etc.), MPLS/Traffic Engineering, Network Security (especially DDoS Detection and Mitigation) and overall network design and architecture (Backbone and DataCenter fabrics).

Since 2017 I moved on to be the Head of Network at SysEleven (now Since 2020, I also spend more time contributing to the Berlin Internet Community for the BCIX (Berlin Internet Exchange) as member of the advisory board.

The community needs and is based on participation from its members. I’ve benefited and enjoyed community driven and organized events and services. I want to give as much time as I can to contribute back to the community.

Network Architecture In Practice
Fiona Weber, Vincentz Petzholtz

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.

Workshop 2
Why we need a DENOG working group for "routing"
Fiona Weber, Vincentz Petzholtz

Over the years many talks and workshops have been held to improve and spread the overall knowledge of BGP and it's knobs, configs and features. These days there are only a few up-to-date and vendor-agnostic references when it comes to design, control plane and forwarding filtering in modern carrier and/or ISP like networks.

We think that DENOG is the perfect organisation to form a group of people willing to contribute their knowledge to create documents containing best practice tips and configurations for the community.

We call the community to participate in the "DENOG Working Group Routing" (wg-routing).
