Village:EMF-IX

Aligned with the Hacks R Us village, EMF-IX Provides to bring a Internet exchange point to the field near Eastnor. Improving the local internet access and performance.

The internet exchange is mostly run by User:Benjojo however there are a handful of other people also running the exchange.

We are over here on the map: https://map.emfcamp.org/#21.51/52.0412073/-2.376054

Exchange Policy
The goal is to beat out the nearest rival exchange, LINX Wales. However should be achievable as the traffic profile for LINX is around 15mbps baseline to 130 mbps peaks.

In 2018 EMF-IX beat LINX Cardiff (as it was known at the time) by 5mbps. So precedent is set.



General peering / exchange policy is as follows;

The Technical Specifications state the following:

There are only three ethertypes allowed:
 * 0x0800 - IPv4
 * 0x0806 - ARP
 * 0x86dd - IPv6

Other ethertypes may be allowed if EMF-IX operators are warned of ahead of time.

By default, Only one MAC address allowed on a port, i.e. all frames sent towards the IX should have exactly one unique MAC address.

The only non-unicast traffic allowed is:


 * Broadcast ARP
 * Multicast ICMPv6 Neighbour Discovery (ND) packets. (NOTE: this does not include Router Advertisement (ND-RA) packets!)
 * You must not broadcast multicast packets into the multicast media LAN

Hosted Machines
Since not everyone can bring systems to EMF, 8 pre-provisioned Dell WYSE 3030 systems are designed to be limited, but also as "Plug and Play" as possible.

The WYSE machines have a Intel Atom CPU of around 450 Passmark and 2GB of RAM. Storage is provided over the IX via ATA_over_Ethernet (AOE).

AOE is used to prevent people from iptables'es-ing away their storage, as this would be quite disadvantageous for any poor soul who does that. Instead the AOE Storage is provided by the IX server (on SSDs) in the flight case. Connected to the internet exchange at 10GbE.

These WYSE systems are entirely PXE booted over the network and while there is eMMC storage on them, We ask members to not touch that.

The original plan was for these machines to be 2007 Mac Mini's, However they proved impossible to purely netboot, and had already had their disks removed. So a switch to the WYSE machines provided a welcome sanity boost, and performance jump!
