INCA Transform Digital conference

John SouterChief Executive Officer

The London Internet ExchangeMay 2014

LINX Mission and Ethos• To facilitate Internet

interconnection, especially through public peering

• To represent the interests of our members in matters of public policy

As a neutral, mutually owned membership

association

• Mutual = owned & operated for the members we serve• Single stakeholder

• Completely open membership• Only technical rules (for network hygiene)

Peering in one slideTransit• Network simply

buys Internet access from an upstream network

• Simple & straightforward

• All your eggs are in the same basket

• All packets carried are on a meter £££

Private peering• One-to-one

connection with another network

• Usually settlement-free

• Doesn’t scale well (40k networks)

• Most networks won’t peer with you(big boys club)

Public peering• One-to-many

connection with other networks

• Usually settlement-free

• Scales well • Open to all• Lots of benefits• Big networks

still won’t peer with you

Rationale for peering?

Peering offers many benefits:•More efficient routing for ISPs–Enables latency sensitive services (e.g. VOIP)

• Saves money–Lower cost to end users and/or more profit

• Gives ISPs & content providers more control–Better services to end users–Lower dependency on things they can’t control

Which organisations peer at LINX?• 65 of the top 100 global networks• Almost all UK ISPs–BT, BSkyB, VirginMedia, TalkTalk, the mobile networks…

• Content provider networks–BBC, Facebook, Google, LinkedIn, Microsoft, Twitter…

• Content delivery networks–Akamai, BitGravity, Edgecast, Limelight, …

• Many of the world’s largest access networks–AboveNet, DT, Level3, NTT, Telefonica, XO, …

OK, I cheated

LINX regional peering initiative• LINX has been very successful in London–Realised that we inhibited regional peering in rest of the UK–That realisation do something about it!• With the full support of our members

• Regional peering initiative was born in late 2011–1st regional exchange opened in Manchester in 2012–2nd exchange opened in Edinburgh in late 2013–3rd should be in Cardiff in mid-2014–Now exploring whether we can open more exchanges in

Northern Ireland and in the regions of England

• Key factor will be support from a local community of interest
