Gartner forecasts that 6.4 billion connected

things will be in use worldwide in 2016, up 30

percent from 2015, and will reach 20.8 billion

by 2020

Worldwide revenues from public cloud

services will reach more than $195 billion in

2020. This will be more than double 2016

revenues and represents a CAGR of 20.4%

our customers are facing a new set of challenges

7

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

In response to this we are…

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

Investment in ultra-high bandwidth “IQ” network: 4 focus areas

Build an Integrated Core and

Metro Packet Network

• Single integrated IP and

Ethernet core network,

covering 200+ data centres

across Europe and Asia

• Delivers 100Mbps to 100Gbps

services via plug and play

model

4 key investments will transform the backbone networks that support our

customer services

• New metro optical network

across 90+ data centres in 13

key cities in Europe and Asia

• Off the shelf delivery of

100Gbps & 200Gbps waves

• Rapid leadtimes – 5 days for

10Gbps waves

High bandwidth optical network

between major data centres

Evolve our voice network

New optical backbone:

“Express” Long Distance Network

• Next generation SIP Trunking

session board controller

• SIP Trunking coverage expansion

to

21 countries

• Build “Express” long haul

network between 30 major

European cities

• Based on architecture optimised

for high bandwidth

Novitas what is the customer need?

Today’s digital economy means our customers can:

Place an order, and it is delivered the next day

Book a taxi via an app, it turns up in minutes

However, most telecom services are still ordered and delivered in the same way they were 20 years ago!

Order cloud IT services and it is delivered in

seconds

10

Novitas what does it mean?

11

NOVITAS transforms the way that network services are ordered and consumed, and brings a cloud like customer experience

Delivery in weeks

Manual configuration

Steep bandwidth vs cost curve

Traditional telco experience

Ethernet on demand (learnings)

Product/sales innovation required (new commercial model)

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

19

SD WAN on demand (enterprise challenges)

More Bandwidth

Flexible Traffic PatternsNeed to increase Agility

Bandwidth requirements increase by

20 – 30% per y ear

while

65% of WAN budgets

are Flat to Declining

Implementing changes(portal driv en, not off-line process)

Adding a new branch site(in hours, not weeks)

Upgrading bandwidth(instantaneous, not days)

Public Cloud impacts WAN traffic patterns

• WAN “break-out” to public Internet no more

centrally , but close touser, e.g. SalesForcetraf fic at customer site

• Need f or Firewall

f unctionality and network-wide policy

CostDelivered using competitively priced public Internet

services, meaning only high priority traffic is routed

across premium MPLS paths.

ResilienceEither network path (MPLS or Internet) can be used

as backup in the event of a failure.

Speed of deliveryUsing customer’s existing Internet Access enables a

much quicker service deployment than OLO tails.

Multi function

CPE

X86 architecture means that one CPE can act as a

router, firewall, or application performance monitor

via a single device.
