About Colt

Summary
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
• MEF / ONF / NFV Member

3
Vision: IT & Network Integration
The integration of the network and IT platforms from
the service, technology, system and process point of
view to deliver an end to end integrated customer
experience (the Information Delivery Platform).

Network automation, virtualisation, elasticity and

rapid innovation
4
Strategy: Programmable Networks
• Networks have evolved into complex, inflexible, closed, proprietary

and

costly systems (very little change in the last 15 years)
– Main reasons: lack of networking principles and abstractions (control plane), lack of
open Network APIs

• In contrast, computing is open, heavily built on abstractions, supporting cloud
paradigm (automation, virtualisation, elasticity, on-demand)

• SDN/Programmable Networks:

IT & Network integration (computing
paradigm for networking / application & network worlds to communicate)
– ONF - Software-Defined Networking: data & control plane separation,
standardisation of fundamental networking abstractions (Per-hop & Overlay)
– IETF - Software-Driven Networking: focus on network APIs to allow applications
and network to exchange information
– NfV – Network Functions virtualisation: standard IT virtualisation technology to
consolidate many network equipment types

•

SDN Overlay: L2-L4 DC Network Virtualisation & DC Architecture

virtualisation of the L3 CPE functionality (Internet access / IPVPN)

NFV**:

** Research

End to end WAN network abstraction & full automation in a multivendor, multi-layer environment
Flexible connectivity, i.e., ability to dynamically / on-demand change the
connectivity attributes of the service (BW, QoS profile, etc).

Summary
• SDN is (still) in its early days. Most of the work by ONF/IETF/NFV still to be
done (long journey). Most SDN products not GA - dust will settle eventually

• Carrier class OpenFlow switches not generally available in the market (2012).
However, DC SDN overlay solutions are a reality (Pilot completed, vendor
selected, deployment on-going in Colt)

• SDN/Network Programmability fits extremely well with Colt’s strategy to
deliver integrated IT & Network services to our customers
– SDN is a key contributor to automation and orchestration/policy (faster
delivery/change, more agility, better utilisation, standard services)

• NFV and service chaining will change the way we deliver L3-L7 services even
more – not just vCPE

• Next initiatives:
– NFV: L3 CPE/DC Appliances/BGP RR

– WAN SDN: L1 Optical / L2-L3 Packet / Inter-DC
– External use cases being discussed with key vendors
