The world around us is changing at a rapid pace

Four mega technology trends transforming IT:

2.5 Trillion Gigabytes

Data created globally each day

6.4 billion

Connected things in use worldwide in 2016

85%

Of enterprises use at least one cloud service today

75%

Of world’s mobile traffic will be video by 2020

BIG DATA INTERNET OF THINGS SHIFT TO THE CLOUD MOBILITY

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%

• ur 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…

Investing in a new ultra-high bandwidth network Introducing a high bandwidth

• ptimised 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 connectivity

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 Today’s cloud experience Real time delivery

Colt NOVITAS

Portal consumed network services, delivered in real time!

Colt SDN/NFV transformation programme (Novitas)

Self- provision Near real-time Interworking with other providers Available through portal and APIs Provides performance analytics

And delivering important benefits:

Supports value added services

Elastic Topology 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 (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 Patterns Need 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) A dding a new branch site (in hours, not weeks) Upgrading bandwidth (instantaneous, not days) Public Cloud impacts WA N traffic patterns

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

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

• Need f or Firewall

f unctionality and network-wide policy management

High WAN Costs

Management SD WAN Controller

Premium Traffic

Internet Best Effort Traffic

Branch site 2 Novitas CPE Cloud

SD-MPLS GW

Customer portal Cost Delivered using competitively priced public Internet services, meaning only high priority traffic is routed across premium MPLS paths. Resilience Either network path (MPLS or Internet) can be used as backup in the event of a failure. Speed of delivery Using 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.
