FAQ

Joining LINX at IXScotland

Can my company become a member?

LINX membership is open to a wide variety of companies. There are some simple requirements to becoming a member:

  • Your company must be a recognised legal entity
  • You must have an ASN (Autonomous System Number) which is visible from the LINX transit router
  • You must use BGP-4 for peerings.

For full details of our membership requirements please see section 1 of our MoU

Can you help me get an ASN?

There are several Regional Internet Registeries which provide internet resource allocations, registration services and co-ordination activities. These are arranged according to geographical location:

  • RIPE for Europe
  • ARIN for North America
  • APNIC for Asia and the Pacific region
  • LACNIC for Latin America and the Caribbean
  • AfriNIC for Africa

If you need help obtaining an ASN these RIR's should be your first point of contact, however, if you have any issues or questions please let us know and we will help where we can.

What equipment will I need?

You can join to LINX using your own router. We require this router to be housed in one of our 10 PoP's (see list below). Alternatively, you can use a layer-2 carrier to peer at the exchange. Please see LINX from Anywhere for a list of carriers.

What types of companies are LINX members?

The LINX membership is made up of a variety of networks who choose to exchange their Internet traffic through co-operative peering agreements. Our members include ISP's, CDN's, eyeball networks, gaming companies, research and education authorities and streaming media networks amongst many others. If your company does not fall into one of these categories please get in touch so that we may discuss our membership with you further.

How much traffic do I need to peer?

For a normal mix of internet traffic we usually find that an ability to peer at least 20mbps works well although your circumstances may vary depending on traffic types and priorities.

What is the joining process?

For a comprehensive description see our joining procedure.
Or, briefly:

  1. The new member must fill in an online application form
  2. Then the member must fill in, sign and return the LINX MoU and Corporate Representation Form and pay their initial LINX membership invoice.

How much will I pay?

Each member has to pay an annual membership fee of £1200 alongside their monthly port fees. You will also be required to pay a one-off installation fee when you join the exchange. For full prices please see our fees page.

What is the LINX contract term?

When you sign our MoU you agree to give LINX 30 days notice of any port or membership cancellation.

Where can I connect to IXScotland?

LINX is located in 1 site in Scotland, UK

  • Pulsant South Gyle, Edinburgh

Connecting to LINX

Do I need a physical presence within the data centres your peering LANs operate from?

Many LINX members peer remotely via a ConneXions partner or though a LINX from Anywhere partner. Some of these members have their equipment located thousands of miles away from the peering LAN they are connected to.

How does the physical connection work?

Members connect in one of three ways:

  • Their own PoP in a LINX enabled Datacentre
  • A layer 2 connection terminating in a LINX enabled Datacentre

need to arrange cabling into one of the LINX PoPs (see above list of PoPs). Once present in one of the PoPs, members will need to make their own arrangements for cabling to the LINX switch with the exception of Telehouse where LINX will order the cabling. LINX will provide the member with the necessary demarcs for the order.

Can I set up transit sessions over LINX as well as peering seesions?

LINX allows both transit and peering across the exchange. Members are free to make their own commercial agreements for traffic exchange.

Can I exchange traffic between two or more of my own routers?

No, a member cannot use the exchange infrastructure to form part of their network's backbone.

Can I point default at other LINX member interfaces?

No

Can I connect through a switch?

Yes As long as only one MAC address (that of your router) is visible to LINX.

Can I use IPv6 on the main peering LANs?

Yes IPv6 is native on the main peering LANs Contact LINX support for v6 peering LAN addresses.

Can I use IPv6 autoconfiguration or site-local addresses?

No. Peering LAN addresses should be allocated by LINX, and explicitly configured.

Can I use Multicast on the main peering LANs?

No. Not on the main peering LANs. It is allowed on the dedicated multicast switch.

Peering at LINX

How does peering at the exchange work?

LINX offers both bi-lateral and multi-lateral peering. Members have the option to peer with the route servers which will provide instant access to many of the other LINX members. Members are expected to contact each other directly to dicuss individual peering opportunities. All member contact details are provided by LINX.

Will networks peer with me if I join LINX?

Whilst members set their own peering policy we observe that over 60% of members operate an open policy with a further 25% being selective. In addition over 70% of members peer using our multi-lateral route servers.

LANs outside of London

Can I reach all LINX peers at IXScotland?

IXScotland is separate from our Juniper and Extreme LANs in London. By connecting to IXScotland you will only be able to reach members who peer on that specific LAN. If you would like to peer with a member who is connected to the exchange in London you will need to order a port on our London based Juniper or Extreme LANs.

About LINX

How does LINX make money?

LINX is a not-for-profit organisation. That means that all profit from membership and port fees is put directly back into the exchange to upgrade the infrastructure.

Why Dual LANs?

Our dual LAN's are designed to offer our members resiliency. If there is an issue with one of our vendor's equipment, the other will still be working to allow our members to continue to pass traffic.

Where are LINX staff based?

The registered office for LINX is located in Peterborough, UK. This is also where the administration, Marketing & Business Development, Member Relations and IT staff are based. LINX also has a second, smaller office in London which is home to the engineering and Public Affairs teams.

Are there meetings prospective members can attend?

Yes, quarterly LINX member meetings are held in London. These are announced on the front page of our website. We also send representatives to many of the major industry meetings including RIPENANOGEPF and GPF.
