Internet Peering Architecture

Multiple ISPs locate backbone nodes in single building operated by co-location provider

In-building connections to shared interconnect fabric using ethernet LAN switching technology

Routing information exchanged bi-laterally between peering ISPs using BGP

IPP operator need not be same organisation as co-location provider

Co-Lo will generally have other customers: carriers, hosting, ASPs, content distributors


IPP Advantages

Reduced bandwidth costs

Improved throughput and latency performance

Economies of scale

Single large pipes to one IPP more efficient than many small private interconnects to many ISPs

Critical mass of ISPs in single location creates competitive market in provision of capacity, transit and services


Peering Points in Europe

Most countries have at least one mainly to keep domestic traffic inside country

Top 5 exchanges keep European traffic inside Europe London, Amsterdam, Stockholm, Frankfurt, Paris 50-100 ISP participants each switch typically several hundred Mbps to several Gbps traffic

Not in general congested

Traditionally early adopters of next generation Ethernet


Our Differences & Strengths

VC funding for-profit €9M in place now

Growth-oriented

Pan-European one-stop shop across multiple cities

Multiple Co-Location providers’ sites in each city

Fast Provisioning

Neutral...


XchangePoint’s Neutrality Principles

ISP and Carrier Neutral we will not compete with our customers we will not move traffic between cities or countries

CoLo Provider Neutral present at 3 CoLo sites per city partner with multiple CoLo providers as customer choice of CoLo sites for our peering customers

VC ownership is Neutral

Service provision will be Neutral

We will not enter into exclusive arrangements


Our Implementation Strategy

We want to partner with existing IPPs where possible & appropriate:

assett transfer/purchase exchange of equity and/or cash outsourcing arrangements distributor arrangements co-operative agreements

Important to keep co-ordination and dialogue channels open in evolving market

We are building, and will build IPPs from scratch where above is not possible and there is a need

Roll-Out plans

Prefer to partner with small number of pan-European CoLo providers

First site Redbus Interhouse - live ! Harbour Exchange in London pilot service available now

Telehouse London during April

Global Switch London during May

Redbus Paris late summer

Looking for customer feedback on further locations


Architecture Overview

2 “Core” nodes per city 10 racks 2 Extreme BlackDiamond switches

2 or more “Basic” nodes per city 5 racks 2 Extreme Alpine switches

Use of DWDM

Bandwidth multiplication non-blocking inter-site architecture becomes possible

Provides extra resilience optical circuit protection faster fail-over than spanning tree

Improves scalability

Permits multiple logical topologies over single physical MAN

Can conserve switched bandwidth by re-routing high volume traffic over dedicated wavelengths


Private Interconnect

Copper and Fibre cross-connect available as a service within Core sites

Can dedicate single wavelength () to private interconnect between two high-volume peering customers

fast & flexible provisioning between sites reduce limited trunking space issues within sites

-interconnect will be available between ISPs only not available for within a customer’s backbone to avoid competing within

conventional carrier business and maintain our neutrality


Ethernet Switches

2 Extreme Black Diamond 6808i switches at Core sites

2 Extreme Alpine 3804 switches at Basic sites

Each switch at each site connected to one of two separate overlay networks

Virtual dual-vendor approach different code on each overlay network’s switches

Dual overlay networks connect at Core nodes maximum flexibility for high bandwidth interconnect within Core


Service Offerings

Copper & Fibre in-building connection

Gigabit Ethernet ports

100baseT Ethernet ports

Private interconnect

Inter-site interconnect Gigabit ethernet, STM-4, STM-16

Out-of-band console access


Value-Added Services

Service Level Agreement rebates for failure to perform

Cisco 7200 Collector router at each core site

Traffic statistics servers

Media converters

Customer dial-in to out-of-band access via ISDN30/Cisco 3640

24x7 pan-European NOC in service 2001 Q3


Future Services

These are budgeted for !

Multicast traffic exchange banging of switch vendor heads together still needed…

IPv6 mostly just addressing

10G Ethernet between switches 2001 Q3

Start thinking about inter-ISP VoIP interconnect issues

Build team will become R&D team
