Full integration of networkand IT service with singleent to end control plane

• System driven workflow (with a number of manual steps)

• Capacity Management• Metering and Billing

• Application driven (“dumb” mode)

• Software-driven, end-to-end control plane

• An application aware network coupled with network aware applications

Ethernet : Universal Access

• Transport mechanism of choice in the access / WAN

• LAN technology in the DC

Connect the two

• How ?• Don’t treat DC as customer premises anymore

• End-to-end connectivity, SLA, QoS, etc: technical and commercial service wrap

• Openflow/own HW: remember not everybody is GOOG

• Don’t forget: It’s also time to stop sell some services, migrate customers and remove technology

8

Does the protocol matter ?

• The service sure does matter... But to which extend ?

• Carrier Ethernet, IPVPN, IP Access ?

• Into the DC

• Pick on the customer’s behalf (solutions) or let him decide (wholesale/retail)... But let him change it in-life and give him visibility

APIs & open protocols & co

• What’s next ?

9

Software-Defined Networking

• aka Network Programmability

• Sounds like a one-way function when networkapplication is as important

• It’s not a protocol, it’s about thinking differently about architectures

• Builds nicely on our Modular MSP model: future OSS

• Isn’t everything already SDN ? So what’s the new model ? Customer-DN, Demand-DN, Application-DN ?

10

So what’s the future like ?

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

• Monolithic MSP/CE solutions are going to be history soon

• Modular, multi-vendor (i.e. IP like) will be the new norm

• Openness, APIs, programmability will prevail over hardware capabilities

• Not just bandwidth and features will change in-life, also the service type

• Managed IT solutions will include and abstract the network

11

But also many open questions

• What’s the future for hardware: Generic ? Home-made and maintained ?

• Cloud had its hype, SDN full in it: what’s left once the dust settles ?

• New operating models for well established carriers and people

• Management of hybrid networks (e.g. capacity)

• And probably many more...
