Colt is evolving its VPN portfolio towards a hybrid of MPLS and SD WAN to address customer challenges around needs for higher bandwidth, faster network delivery, and more network agility. It is initially focusing on an SD WAN minimum viable product to directly address new market demand. Longer term, Colt aims to develop a unified, automated on-demand platform powered by network virtualization, orchestration, and artificial intelligence to further optimize services.

4. (L3) VPN customer challenges
Need for higher
bandwidth
Customer demand has a strong growth
- WAN bandwidth requirements are increasing above 30% per annum every year (Gartner)
- SD-WAN traffic will grow at a CAGR of 44% compared to 5% for traditional WAN (Cisco VNI)
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
