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
