Join the Infrastructure¶
If you are part of an organization and/or you are commited to do research with SCION, and using user ASes is not enough for your plans, then you could join SCIONLab with a dedicated host. We have compiled a short guide to document the requirements. You can join the SCIONLab network as an infrastructure AS with one or more machines, or you can start as small as dedicating only a simple commodity PC. If you have decided to join SCIONLab as a permanent node in the infrastructure, check that your new node(s) can comply with the requirements. Then, just follow the procedure!
There are a few requirements for you or your organization to join SCIONLab as an infrastructure node:
- Infrastructure ASes and nodes are required to be active 24 hours a day, 7 days a week. The SCIONLab administrators can typically handle all SCION related problems, but sometimes they will contact you if they cannot perform certain tasks. An example would be to change a drive if it failed, etc.
- The machine must have a minimum of 4 Gb of RAM. A VM can suffice, given sufficient resources.
- Currently the SCION code works with Ubuntu 16.04.
- The border router node(s) must have a public static IP.
- The following are the traffic types and the corresponding ports SCIONLab requires at this moment.
- SSH: TCP 22: source 184.108.40.206/20, 220.127.116.11/21, 18.104.22.168/24, 22.214.171.124/12
- OpenVPN: UDP 1194: source any
- HTTP: TCP 8000: source any
- Monitoring: TCP 8080,9200,9900: source any
- Management: TCP 9100: source any
- Scion packet: UDP 50000~50010: source any
The following are not requirements, but recommendations:
- The border router should be near (latency wise) the IP border of your AS or organization.
- Co-locating the node or nodes in your datacenter is usually a good idea in terms of network latency.
- To join the SCION network, we have a specific hardware recommendation: HP Proliant DL20 gen9. We further customize the machine with additional 8G ECC Ram and SSD, but a regular HDD also works.
- Instead of a blade type server machine, a regular PC with a similar spec works as well.
You can connect to the SCIONLab infrastructgure through the following steps:
- Get in contact with us. Send us an email to email@example.com telling us you want to join the infrastructure.
- Once the node(s) are ready, create a user with the name
scionand permission to run
sudo. Grant the SCIONLab admins
sshaccess to the machine via a key for that
- The SCIONLab admins will perform some measurements to find the appropriate neighbors to your AS. We will notify you of the result.
- Once the neighboring ASes have been decided, the administrators will install the necessary services of SCION and monitoring. This is typically done by us using
Ansible. We deploy the configuration of the node(s) in the AS at the same time.
- Your AS is now connected to the infrastructure of SCIONLab and hosts within your network now have direct access to SCIONLab.
