4. our customers are facing a new set of challenges
4
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”

5. 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
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

 Initial technical complexity
(IPSEC/MPLS/BGP)
 Not 100% technology maturity
 Compute performance limitations
 Self-Install / ZTP a must
 Big change in the operating &
development model
 Strong customer demand (renewal
requirement)
