our customers are facing a new set of challenges

Need for

higher

bandwidth

Customer demand has a strong growth:

WAN bandwidth requirements are

increasing above 30% per annum every

year

Customers can set up new cloud services in minutes, yet delivery

times for new VPN sites and Ethernet connections are still

measured in weeks and months.

Radically faster

network

delivery

Need for more

in-life agility

Cost efficient

scaling

Cloud services can be scaled up and down on demand, while

bandwidth upgrades and feature changes for the network are

traditionally manually requested and take days/weeks to deliver

Since 65% of WAN budgets are flat or declining, cost efficient

scaling of bandwidth is crucial.

“With a progressive uptake of video, IP audio and cloud, the compound

annual growth rate (CAGR) of IP traffic is above 30% per year”

In response to this we are…

5

Investing in a new ultra-high bandwidth network

Introducing a high bandwidth optimised portfolio

Launching On Demand and Software Defined WAN Services

Further increasing focus on Enterprise market

Elastic

Service

Deliver programmable flexible topologies

based on overlay and underlay networks.

Deliver virtualised off-net and on-net L2 and

L3 edge services on top of basic connectivity.

SDN

NFV

Elastic

Bandwidth

Deliver programmable elastic links with

variable bandwidth.

The Vision: to transform the way network services are ordered and consumed, delivering a cloud like customer experience (self-provision, in real-time)

Ethernet on demand (learnings)

Product/sales innovation required

Full leadership support a must

Equal priority to API and Portal/GUI

Agile development requires internal alignment & agreements

Commercial APIs (NB & SB) not 100% mature

IT development trade offs (java vs cloud)

Effective automation requires a clean inventory

OPS transformation is paramount
