Colt – The Information Delivery Platform
• 44,000km EU high capacity long
distance network, 27,000 transatlantic
• Connecting 22 countries, 39 metro
networks and >150 cities
• 20 data centres and 19,000 connected
buildings
• 500+ NNIs, customers in 77 countries
4
Colt’s IP Network Overview
• Business customers only
• Coverage: Focus on EU (13 countries, 44 cities); extensive EU IP peerings and US East Coast presence completed by E-NNIs and MPLS-NNIs
• Data Centres: 20 DCs in 14 cities in 10 EU countries (30,000 +sqm)
• Routing: AS (8220); ISIS (single area, 2-level); MPLS (LDP)
• Size: 350+ PE; 60+ P; 20+ PR; 30K+ CPEs
• Core Links: n*10GE
• Services: Internet Access (and Transit); MPLS IPVPN, VoIP
• Integrated network: same PE/P for Internet & VPN
• Access connectivity: Ethernet (on-net & off-net); DSL (Ethernet ULL & ATM/L2TP wholesale DSL); MPLS-NNI (type A/B); TDM (off-net)

Colt IPv6 Strategy for Business Customers
• Business customer requirements led to Dual-Stack
– Same IP services/features delivered over native & parallel IPv4/IPv6
• The sooner it can be offered the earlier customers will be able to start their own learning and transition
– Customer education is key!
• Colt’s short to mid term strategy: Dual-Stack
– 6PE & 6VPE (MPLS transport)
– IP services & features seamlessly developed for IPv4/IPv6
– Colt’s IPv4 address pool at current allocation rate: 3+ years

Colt IPv6 Case Study
• Colt is hopefully a representative use case for IPv6 business-only service provider
– Typically the focus is still on residential SPs (due to IPv4 address exhaustion)
• It can also be of interest to enterprises when planning for their internal projects
• Colt IPv6 Project phases:
– Internal business case
– Infrastructure design & implementation
– Product development
7
Colt IPv6 CS (I) : Internal Business Case
• First IPv6 conference attended: 2nd Global IPv6 Summit (Madrid 2002)
– “IPv6 is a reality: It's not an illusion, it's a need”
• Architecture & design teams tried to raise an IPv6 project several times in the period 2002-2008, but:
– There were no customer demand
– IPv4 exhaustion was still not critical
– Therefore: It was not possible to build the business case for IPv6
• 2009 was the inflexion point in Colt:
– IPv4 exhaustion started to have more external visibility
– A new business case was built accounting for all IP product revenue at risk
– Intensive IPv6 internal education campaign (product & management)
– IPv6 infrastructure project was approved to start in 2010
– IPv6 product development approved to start in 2011
8
Colt IPv6 CS (II) : Infrastructure Design & Implementation
• IPv6 Infrastructure project started in Q1 2010
• Scope: IPv4/IPv6 Dual-stack across Network & OSS
– Network:
• MPLS transport in the core (IPv4 IS-IS/LDP)
• 6PE (Internet), 6VPE (IPVPN) in the access
• Full network upgrade completed Q3 2012
– OSS:
• Dual-Stack across all major OSS systems (monitoring, performance, provisioning, Syslog, Mail, DNS, Radius, NTP, etc.
• Just completed Q2 2013
• First alpha Internet transit service: V6WC Paris 2011
– Early setup based on limited 6PE deployment
• World IPv6 Day (www.colt.net) 8 June 2011
– Use case on how to quickly bring IPv6 web content online

Colt IPv6 CS (III) : Product Strategy
• No commercial distinction between v4/v6 traffic
• Enable all existing IP products and features for IPv6
• Deliver the required flexibility to support customer’s own transition plans
• Eventual (long-term) withdrawal of all products and features not compatible with IPv6
• Business Customer – IPv6 Reality assessment:
– Interest restricted to early-adopters & large corporations
– The greater mass of smaller customers are being very reactive, not considering IPv6 at the moment
– Questions about Colt’s IPv6 support & roadmap in RFPs have significantly increased
12
Colt IPv6 CS (III) : Product Development
• Basic IPv6 product development project
– Basic Internet Access service (“wires-only”, i.e., unmanaged service) started in Q1 2011
– Learning approach
– Beta trial started June 2011 with 19 customers all around Europe
– Service officially launched Q4 2012
• Full IPv6 product development project
– Dual-Stack full feature parity for Internet Access & IPVPN (started Q3 2011)
– 3 phase approach (feature prioritisation)
– Phase 1 about to be launched. Phase 2/3 Q4 2013
– Tactical transition techniques analysed in Phase 3
13
What Next After Dual-Stack?
• Dual-Stack is good but …
– it is quite likely that it will not be enough
– and customers will request tactical transition tools
– what are the other techniques that could help and are suited for business customers?
• Colt’s plans beyond Dual-stack :
– IPv4 address preservation techniques (short term)
– NAT64 “in the cloud”
• IPv4 customer content visible in IPv6 Internet (short term)
• IPv6 customer content visible in IPv4 Internet (mid/long term)
• IPv6 customer end user access to IPv4 Internet (long term)
• Transition techniques will be implemented in existing PE devices (using available service cards), local to each IP PoP
14
Summary
• Dual-Stack is Colt’s IPv6 strategy for business customers
• Lessons learnt
– Internal business case is always difficult to sell
• Internal education a must
– Training is fundamental
• Well spent money
– OSS is where we have found most of the issues
• The network was much easier
– Customer education should be done in early stages
• Periodic sessions with customers
• No magic solution (unfortunately) for business customers
– Every customer will have to go through its own migration
• Don’t panic, but do start your own project now (if you haven’t already)
