Colt’s SDN and NFV current & future development
L3 CPE
virtualisation
(NLI)
L3 CPE router virtualisation:
• virtualisation of the L3 CPE functionality (Internet access / IPVPN) in the
cloud
DC Fabric &
Network
virtualisation
(CCN)
DC Fabric
• OpenFlow DC Fabric evaluation
DC Network virtualisation:
• Virtual Network decoupled from physical hardware.
• VMs unrestricted placement & mobility.
• Dynamic network policies.
• Address Space virtualisation (VLAN/MAC).
• Network Virtual Services APIs
• Network Automation (APIs & orchestration)
WAN SDN
(NLI / Mod MSP)
WAN SDN Network (Optical/Ethernet/IP):
• WAN network virtualisation & automation
• End-to-end unified network abstraction allowing for true technology
layer & vendor integration.
10
Colt SDN Application I : L3 CPE virtualisation
• Objective: avoid deploying a dedicated L3 CPE router by virtualizing its
functionality: significant Opex & Capex savings and source of innovation !
• Part of NLI (Network Layer Integration) project started in 2011
• Phase 1: L3 CPE virtualisation based on L3 PE functionality (both Hw & Sw)
– Basic Internet Access launched
– Work in progress: Internet Access with advanced features and IPVPN
• Phase 2a: cloud L3 virtual CPE
– Virtualize the L3 CPE functionality in the Cloud (as per NfV)
– Other functions in the radar: FW, LB, WAN Optimisation
• Phase 2b: OpenFlow CPE (tentative)
– Integrated CPE with OpenFlow functionality
– Rich L3 CPE functionality delivered from the PE or from NfV
– Greatly simplify carrier Ethernet CPE functionality

Colt SDN Application II :
• DC Network virtualized, but WAN remains static, rigid and complex
• Next step (research mode) to bring SDN to the WAN (L1/L2/L3) : WAN virtualisation &
automation:
– Flexible connectivity
– Dynamic / On-demand connectivity attributes (BW, QoS profile)
– WAN Network abstraction (multi-vendor, multi-layer)
– In-life service-type change
• Colt interested in both DC and non-DC WAN scenarios:
– Cloud Inter-DC (data & storage)
– Enterprise to DC (Public / Private Cloud)
– Enterprise to Enterprise Optical & Carrier Ethernet VPN
• WAN SDN overlay solutions seem current realistic approach (several models):
– OpenFlow (with transport extensions if needed) agents in WAN network devices: standard API for
configuration, monitoring & configuration
– Alternative to manage OF agent at the SDN controller plus other classic protocols (SNMP, etc)
– Existing transport control planes available (RSVP-TE, GMPLS, etc) for overlay solutions
– A mixed set of models (Overlay/Hybrid/OSS-based) to be analysed

Summary
• SDN/NFV still too upstream/abstract for most CIOs ?
• Engage with your customers, find out what they need / want that can help
their business problems (not just a cheaper service)
• Many still focus on visibility, portal over APIs and «bandwidth flexing»
• Impact of accelerated pace of change and new consumption models
• Not just HW vs SW cycles – not everything is doable in SW
• Not-so-GA products, creative and complex licensing models
• « research, RFx, development, TAT, deployment» every 6 months ?
• 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
