Network design
There will be a flat network with a single uplink. Nothing is known yet about the availability of public ip space. Depending on the availability of the hardware, the topology will either be ring or star based. In both situations, multiple distribution switches will be available on the fields. Due to the decision to deliver a stable and robust network, the plans for setting up multiple vlan's to prevent abuse is dropped. Instead, a flat network will be created. There will be a separate vlan for hacking purposes, if you'd like a port in there, contact noc@ when laying a cable to a distribution point. Please note, there is, as of yet, NO WIFI AVAILABLE. However, if someone is willing and able to provide us with an AP, we're reachable via noc@ :)
Topology
A star topology has been chosen, since this creates a bit more robust field-to-core transport. Yes, a single core is a SPOF, but it's all we have. Below is the intended design:
Available network ranges
The available network ranges are picked out of the following IPv4/6 ranges:
10.42.122.0/23 (255.255.252.0) 2001:7b8:607:122::/64
| range | purpose |
|---|---|
| 10.42.122.1..100 | Infrastructure devices |
| 10.42.122.101..200 | Game servers |
| 10.42.122.201..250 | RFC 2322 dhcp |
| 10.42.123.0..253 | dynamic dhcp |
Network facilities
The organisation will provide DHCP/DNS/rtadvd servers, together with rate-limited and firewalled low-bandwith internet. Both IPv4 and IPv6 will be automatically provisioned if you let your machine do autoconfiguration. There will also be multiple file / gaming serves on the network, of which a list is provided below:
| service | ipaddr | provided by | details |
|---|---|---|---|
| ftp | 10.42.122.51 | mononoke | 2TB raid5 / ubuntu |
| Gameservers | n/a | Slackville | 3 gameservers with several games |
Getting uplink
When you've setup all your gear, lay a cable to one of the distribution points. Noc engineers will periodically scan all the distribution points to connect all the cable's there. Under no circumstances it's permitted that you connect your own cable yourself!
Hacking
No hacking of other systems is allowed on this event. If you're caught you'll be subjected to the dutch laws and we'll be glad to hand you over to local authorities.
- Mathijs: Perhaps an idea to organise a hacking contest on this special vlan? (See special hacking vlan, let it organise itself :)
Network hardware
Hardware to be used in the NOC, field distribution and end users connectivity.
