How much to expose / what to rethink ?

Customers

Service Provider

• SDN: SP internal only ? Customer agnostic or specific ?

• Initial delivery (incl. zero-touch and activation) vs in-life changes (and type of changes)

• Systems and processes changes

• Performance monitoring

• Portals and APIs

• Telco vs IT approach

The path towards network and IT programmability

Manual Semi-Automated Automated On-demand Programmability

Service Catalog driven order and provisioning of IT and network

services, Customer Portal for MAC, Service Assurance

Automation, Service Visualizationand Reporting

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

• Incremental vs [color]field

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

• Carrier Cloud: end-to-end connectivity, SLA and QoS

• 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

Modular Carrier Ethernet

Next-Gen DC Fabric

15

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

Network Layer Integration

Managed IT

16

Software-Defined Networking

• aka Network Programmability

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

• It’s not about a protocol, it’s about thinking differently about architectures (networks and systems and apps)

• Virtual CPE and firewalls today

• Many more functions in the future

Cloud Centric Network

Functions virtualization

17

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) and packet-oriented at all layers will be the new norm

• Openness, APIs, programmability will prevail over hardware capabilities: network functions will be virtualized

• Managed IT solutions will include and abstract the network

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

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

• New operating models for well established carriers and people
