Colt WAN SDN Application

• 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

• Iinterest 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 realistic (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

Conclusion and next steps

• Ethernet is the de-facto access technology for WAN and DC LAN

• Monolithic MSP/CE solutions are history: modular, multi-vendor (i.e.

IP like) are real and will become the new norm

• Next we will review the opportunity to introduce a 2nd vendor in each

domain, add 100G as well as making sure our service proposition is

consistent across EU

• Pushing the envelope also implies challenges, it was a very

interesting journey that isn’t just a technology step-change but also

an operating model one

• Not just a like-for-like technology replacement and evolution, but also

new services, capabilities and features for our customers !
