Introduction: IP interconnection (peering, BGP) and the legal status of the organisations that operate them<\/h2>

An Internet Exchange Point (IXP) is an infrastructure where networks (autonomous systems, or ASNs) connect to exchange IP traffic directly. These may include operators, content providers, public services, large companies or start-ups, though this list is by no means exhaustive. By bringing together networks that wish to connect, it shortens the path taken by data flows, improves latency, creates new routes, and enhances a region\u2019s redundancy and autonomy. The Internet Society (ISOC) points out that an IXP is a physical, neutral location where networks meet to exchange their local traffic.<\/p>

Some IXPs are set up by associations, others are academic (set up by universities or research organisations), whilst others are private companies. An IXP may also be operated by a private company, which is itself wholly controlled by an association; indeed, this is the most common model in Europe amongst the major IXPs (DE-CIX, AMS-IX, France-IX). Some associations have not deemed it necessary to set up an umbrella organisation and manage their IXP directly. This is the case with LINX in London.<\/p>

An IXP essentially provides peering (at Layer 2 of the OSI model), but it may also offer Ethernet circuits, cloud connectivity services and Layer 3 routed interconnection. It is generally constrained by issues of competition with its own members\/customers and therefore cannot offer all services without risking competing with, and consequently upsetting, its members\/customers.<\/p>

This diversity of organisational structures is a enduring feature of the European ecosystem. Euro-IX, the European association of IXPs, was established in 2001 to advance the Internet exchange community, in particular through the sharing of knowledge, procedures, statistics and common practices. For its part, ISOC emphasises that commercial, non-profit and community-based models cater to different situations and bring specific benefits to their respective environments.<\/p>

Editorial perspective. This article does not seek to identify a \u00abbest\u00bb model. It offers a framework for analysis: understanding who controls the infrastructure, who operates it, what services it provides and under what rules, and then examining the practical consequences of these choices.<\/p>

Four questions to ask before classifying an IXP<\/h2>

1. Who is in charge of the organisation?<\/h3>

The first question concerns the decision-making centre.<\/p>
