What is Peering?

Internet peering has been the primary method of exchanging Internet traffic in Europe for over 25 years. Used by both large and small networks to aggregate groups of peers on to an efficient and cost-effective service. This is done by using a shared switching fabric based on layer 2 Ethernet technology.

Networks are able to connect using a single physical port or use multiple ports together to create a large single virtual port. Once connected to a public peering exchange, networks can setup or remove interconnections to other networks without needing to physically reprovision any circuits.

LINX Members can host their hardware within the same data centre that hosts our shared switching fabric or they can connect from many miles away and peer remotely via a layer 2 carrier network.

All ports are using single mode fibre and optics. For 1G, we support 1000BASE-LX, for 10G it is 10GBASE-LR and for 100G it is 100GBASE-LR4. On our Manchester LAN we also support BiDI transceivers.

LINX has the most unique member ASNs peering at their locations in London. This means that networks can meet the right peers with just one connection to LINX.

The LINX mission has always been to keep traffic local.

Over the years the Internet has evolved and access speeds have increased. The definition of what local means has also needed to be redefined. Responding to this challenge, LINX consults with network operators all round the UK about enabling networks to publicly peer outside of London.

Network resilience, security and low latency are just some of the benefits of peering at LINX. Members also benefit from public affairs and governance guidance and the opportunity to attend the member conferences 3 x per year.

We have some of the largest networks in the World peering at LINX.

Peering Automation at Facebook

“Traffic on the internet travels across many different kinds of links. A fast and reliable way to exchange traffic between different networks and service providers is through peering…”

“Initially, we managed peering via a time-intensive manual process. Reliable peering is essential for Facebook and for everyone’s internet use.”

Internet Society Explainer: What is Internet Peering?

Most peering agreements require the network operators to have the following:

  • a publicly routed autonomous system number (ASN),
  • one block of public IP addresses, and
  • a network edge router capable of running Border Gateway Protocol.

Bilateral & Multilateral Peering

To generate traffic you will need to set-up sessions with the other participating networks.

Traditionally this was done via bilateral peering agreements. Networks would either meet face to face or request to peer via email. The administration of dealing with hundreds of peers lead to the development of multilateral peering(MLP). Instead of negotiating with each network present, networks can use a single agreement / BGP session to access tens of thousands of route prefixes. A network can arrange instant peering with a large group of peers. MLP is recommended for new members who want traffic flowing from day one.

Remote Peering

For networks looking to join LINX from outside of a LINX enabled data centre, we work closely with a number of global carrier partners in order to facilitate this. These partners are branded LINX ConneXions Resellers Partners.

Our ConneXions Reseller partners allow us to welcome networks from all over the World to peer at the key LINX locations in the UK and US.
