Free admission
Nomikai (party) afterwards


This meeting will include a technical presentation followed by a nomikai.


During this meeting we will talk about Wakame-vdc's and OpenVNet's dynamic scalable firewall functionality aka Security Groups. Security Groups allow you to block traffic between separate groups of interfaces while only opening specific udp/tcp ports.

Topic will include:

  • Wakame-vdc's security groups using Linux Netfilter (iptables, ebtables)
  • OpenVNet's security groups using OpenFlow
  • How we built a stateful firewall using stateless OpenFlow
