The document outlines Colt's SDN and NFV transformation roadmap, highlighting the growth in WAN bandwidth demand and the need for agile, cost-efficient scaling of cloud services. It details Colt's plans to implement a new ultra-high bandwidth network, self-provisioned services, and performance analytics to enhance customer experience. The content also discusses the development of various capabilities under the Novitas program and the importance of standardization in SDN/NFV APIs for operational efficiency.

4. 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”

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
