Public Peering

 

 

 

Public peering has been the primary method of exchanging traffic in Europe for over 20 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 re-provision any circuits. 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. LINX has two remote peering solutions one called LINX from Anywhere and the other is called ConneXions.

To support the LINX regional peering strategy members recently voted to remove all port fees for 1GE ports meaning that currently, members can now peer at any of LINX’s six LANS purely for the price of their annual £1200 membership fee.

This reduction in costs now gives members

  • Added incentive to peer at all our local exchanges
  • More peering at local exchanges makes the Internet faster and more reliable for end users
  • Better connectivity for businesses which stimulates the local economy
  • Lower cost of entry for SMEs

Launched in 2012, the Manchester Exchange (IXManchester) is located at 3 sites in Manchester. Two sites are based at Telecity in Williams House and Joule House and the third is based at the M247 data cente in Manchester. Members are also able to organise connectivity from the adjacent Telecity Kilburn house to Williams House to gain access.

The Exchange has over 70 member connected ports, 18 of which are 10GE. There is a good mix of content providers and access networks present at the exchange including Akamai, BBC, Janet and Virgin Media, as well as local companies such as GammaTelecom and Metronet.

Bilateral & Multilateral Peering

To generate traffic in Manchester 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.

Public Peering Consultations

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 has consulted with network operators all round the UK about enabling networks to publicly peer outside of London. We have called this the local peering initiative.


Regional Peering Strategy Document

Further Information

We have produced a regional peering strategy document, which outlines the benefits of regional peering, and the methodology deployed when building Regional exchanges.

With over 710 members connecting from over 69 different countries worldwide, LINX members have access to direct routes from a large number of diverse international peering partners.
