Dear SwiNOG community,
We’ve just released the agenda for SwiNOG #31 on Tuesday 30.05.2017 on top of Gurten.
I even heard that apparently, we could book the place with a nice-weather-and-sunshine
package. Rumours I guess, but thank you Roman ;-)
Registration ends 24.05.2017 23:59:00, after that - please write us for late reg (with
Freifunk; not a Hotspot solution | Magnus Frühling
Freifunk is a community project, first mentioned 2002, connecting humans all over Germany
and further. I will present why Freifunk is more than just hotspots. Freifunks brings
people together and educates them while building an open, uncensored and local mesh
Open Ethernet Switches - Decoupling Switch Software and Hardware | Arne Heitmann
This presentation gives an introduction and overview to addressing network functionality
independently from specifically coupled hardware and NOS via open APIs and drivers. It
discusses the trends and options for using open OSs for network operations and will show
different architectural models, like ONIE (Open Network Install Environment), SwitchDev
DANE/DNSSEC | Daniel Stirnimann (SWITCH-CERT)
Why do we trust an encrypted TLS connection? We trust it because the server certificate
has been signed by one of the public certificate authorities for which your application
(e.g. browser) has its public key pre-installed. But can we really trust the CAs? And how
can we improve TLS encryption for applications such as mail where certificate warnings
cannot be shown to the user? DANE (TLSA) specifies a protocol for publishing TLS server
certificate associations via DNSSEC. The presentation will show the benefit of
authenticated DNS data, provide usage guidance for the TLSA record. A brief .CH domain
name TLSA survey. Summarizes application support for DANE/DNSSEC. Also, a very short demo
of an unsigned domain take-over to issue a domain validated certificate.
VXLAN - Thinking outside the (DC)Box | Christian Kuster (Huawei)
SwissIX Update | Christian Wittenhorst (SwissIX)
Multi-tenancy with EVPN-VxLAN in Open Networking | Attilla de Groot (Cumulus Networks)
Open Networking or "Web scale networking" is the concept where you're no
longer tied into a single vendor for a network solution. You're free to choose your
own hardware and software. Cumulus Networks has developed a Linux distribution that runs
on switches in this concept.
VxLAN has become the default overlay technology in modern datacenter design. Vendors have
implemented their own control plane for VxLAN tunnels in DCs. The EVPN standard (RFC7432)
provides a control plane that is interoperable between vendors.
We have implemented EVPN-VxLAN support that allows an overlay network being built with BGP
as the control plane protocol. At this time, there is support for L2 functionalities, but
there is ongoing development on support for L3 features such as VxLAN routing with
In this talk these new features will be shown, the details of the protocol and the
design/security implications for large scale datacenter networks.
L3 Routing to Hypervisor | Vincent Bernat (Exoscale)
A common strategy for hypervisors in cloud is to act as a bridge for the client virtual
machines. This provides a known environment for clients used to flat networks and DHCP.
However, this limits scalability and resilience. To solve those issues, a hypervisor
running Linux can be turned into a BGP-controlled router while still exposing a flat L2
network to clients. Presenter is myself. I need 30 minutes for talk and live demo. If
needed, I can use more time since I have a lot of technical details I can share.

Network Automation – Road trip to an automated Network | Urs Baumann (INS - Institute for
SDN is on the top of the hype cycle and its definition gives a lot of room for
interpretation. But do we really need the whole SDN stack to take advantage of it?
Most SDN solutions are anyway based on proven technologies which are well-known for many
years. In this speech, I will focus on the Network Automation part of SDN, I will show you
examples of „low hanging fruits", describe ways of how to start with the
implementation of network automation and how to grow it to a fully automated network.

Looking forward to seeing all of you!!!
