© XchangePoint 2001 What we are doing  XchangePoint is operating and building infrastructure across Europe to provide state of the art interconnection facilities between service providers on an open, neutral, customer- focussed commercial basis.  We are fully funded and open for business in London, and plan to open in several other major European cities in 2001/2.  Our services support not just public switched peering between traditional ISPs, but other forms of metro-area IP interconnection available to any appropriate party using a range of innovative and resilient technologies.

© XchangePoint 2001 Who we are  Board, Founders, Investors, Advisors:   Management team:  Annette Nabavi, CEO  Keith Mitchell, CTO  Brett Wilde, COO  Jeff Meulman, Director of Sales  Engineering team: 6  Sales & Marketing team: 2  Finance/Planning/Admin: 3

© XchangePoint 2001 Our Differences & Strengths  VC funding  for-profit  €9M in place now  not a membership organisation  Non-restrictive participation  Pan-European  Multiple Co-Location providers’ sites in each city  Private Interconnect as well as Public Peering  Fast Provisioning  Neutrality….

© XchangePoint 2001 XchangePoint’s Neutrality Principles  VC ownership is Neutral  ISP and Carrier Neutral  we will not directly compete with our customers  we will not move traffic between cities or countries  no exclusive arrangements  We only interconnect between CoLo sites  CoLo Provider Neutral  partner with multiple CoLo providers as customer  choice of CoLo sites for our peering customers  no exclusive arrangements  Service provision will remain Neutral

© XchangePoint 2001 Planned Roll-Out  First Round Sites  London  Second Round Sites  Paris (Q4 2001)  Frankfurt (Q1 2002)  Proposed Sites  Milan  Madrid  Munich/Hamburg  Geneva/Zurich  Brussels  Copenhagen  Amsterdam  Vienna

© XchangePoint 2001 Architecture Overview  Present at  3 co-location sites per city  Dark fibre metro ring connecting all sites in city  2 “Core” sites per city  10 racks  2 or more “Basic” sites per city  3-5 racks  DWDM equipment at all sites  Gigabit Ethernet between switches and sites  10-Gigabit capable

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 wavelength overlay networks  Virtual dual-vendor approach  different code on each overlay network’s switches  easy to switch half of network to alternative vendor (e.g. Foundry)  Dual overlay networks connect at Core nodes  maximum flexibility for high bandwidth interconnect within Core

© XchangePoint 2001 DWDM Advantages  Bandwidth multiplication  Provides extra resilience  optical circuit protection around ring  or use inter-switch trunking for each ring path éfaster fail-over than spanning tree  New services  Inter-site Private Interconnect  Improves scalability  Permits multiple logical topologies over single physical MAN  Can conserve switched bandwidth

Private Interconnect  Targetted at customers with requirements for:  high traffic volumes  dedicated capacity  additional security/resilience  Copper and Fibre cross-connect available as a service within sites  Virtual private interconnect using VLAN-based Ethernet  Optical private interconnect using dedicated DWDM /channel  Gigabit Ethernet  STM-4, STM-16  T3, STM-1, STM-64 options Q1/  Protected and unprotected options

© XchangePoint 2001 VLAN-based Services  Demand in market for:  Point-to-Point Virtual Private interconnects using 100Mb/s Ethernet  “Closed User Group” Virtual Private Exchanges  e.g. for:  connecting transit customers to wholesaler  higher levels of security and robustness  peering communities with particular requirements  Lower cost than optical private interconnect, easy migration path  Can mix these services with public peering on same port, provided customer router supports 802.1q tagged VLANs and sub-interfaces  Nominal set-up fees  Can be used a VPN service, but not main target audience

© XchangePoint 2001 Current London Locations  Core Sites:  Redbus Interhouse, Harbour Exchange  Telehouse East, East India  Basic Sites:  Global Switch, East India  Telehouse North, East India  Considering additional London sites

© XchangePoint 2001 Redbus Interhouse and Telehouse Nodes

© XchangePoint 2001 Service Status  London network has been live for nearly 4 months  Service trial successful, completed end September:  10 public peering participants  peaking 80Mb/s traffic  have met SLA targets throughout trial  Currently converting trial customers to paying ones  Full SLA for paying customers from October 1st  Web site recently overhauled with new product info

© XchangePoint 2001 Current Traffic

© XchangePoint 2001 Current Customers  Mailbox  NewNet  Verio  AboveNet  Intensive  Nildram  XO  Star  Level3  Nextra

© XchangePoint 2001 Service Offerings  Copper & fibre in-building connection to node:  MetroXP Install  Public Switched Peering:  MetroXP 1000:Gigabit Ethernet  MetroXP 100:100baseT Ethernet  Private Switched Peering (VLAN):  MetroXP vConnect 100:Virtual private interconnect  MetroVPX:Virtual private exchange  Private Interconnect:  MetroXP Connect: In-site wiring  MetroXP Connect 1000: Gigabit inter-site  MetroXP Connect 622, 2400: SDH inter-site

© XchangePoint 2001 Service Pricing  Prices in UK£ sterling, excluding VAT  Annual fees billed quarterly in advance

© XchangePoint 2001 Service Level Agreement Commitments   Service provision within 10 days of order  Response to 24x7 customer support requests  Availability: 99.97%  Lower level of 99.9% for single-homed customers and unprotected circuits  Packet loss:  0% within single site  0.05% between sites  Rebates for failure to perform

© XchangePoint 2001 Acceptable Use Policy   Designed to:  be minimally restrictive  protect customers and infrastructure from malice/accidents  Main principles:  nature of traffic and commercial terms are purely bi-lateral matter for peers  don’t do anything that affects other customers adversely  More constraints for public peering than private interconnect  e.g. AS number and PI address space needed for public peering  “Non-standard” traffic addressed in SLA rather than AUP

© XchangePoint 2001 Value-Added Services  Cisco 7200 Collector router  Traffic statistics servers  per-customer private stats option  MetroXP Console: Out-of-band access  Customer dial-in/telnet via ISDN30/Cisco 3640  Media convertors  fibre/copper

© XchangePoint 2001 New Services  IPv6  we finally have our address space !  address allocations made to existing customers  mix IPv4 and IPv6 on same port ?  MetroXP Multipeer: Optional MLPA router  Have been awarded contract to host one of 5 Nominet.uk secondary name servers  Customer private web pages

© XchangePoint 2001 Future Services  Multicast traffic exchange  will probably require dedicated additional switch network, due to non-interoperability between different vendors:  Cisco RGMP now open Internet Draft  Foundry support PIM snooping  Extreme might support MBGP snooping  community needs to bang switch vendors’ heads together on this  Sub-gigabit private interconnect Q  E3/T3, 100baseFX, STM-1/4  10G Ethernet between switches Q  new switch models  24x7 pan-European NOC
