2. A Legacy MPLS/IP VPN

We know this is a legacy style WAN:
• Internet is delivered centrally from a
dedicated on-net firewall or worse still on
a customer off-net location
• Branch sites have 1.5Mbps which used
to be enough bandwidth
• Every site had the same reliable SLA
regardless of criticality
• 3-6 CoS to sacrifice ‘low priority’ traffic in
order to preserve critical traffic and allow
VoIP + Data convergence

Secure access to an
increasing number of
services, sites and devices
in a borderless network
Leverage the agility
of cloud to support
your digital
transformation
Expand and scale to new
locations
Grow and transform
to a digitally enabled
agile organization
Maximize your
Customer
Experience
Do so in a cost effective way
IT moving towards ITaaS model

4. What’s Your Digital Strategy
• Market opportunity for the dynamic, agile business
has created a race to compete through digitisation
• Digitisation - Real-time visibility of all the variables
with big data analytics to make Machine 2 Machine
and Human 2 Machine decisions and dynamically
react
• Agility & Scale of XaaS models allow customers to
control and improve their UX
• It’s about outsourcing an operation so that you
are free to differentiate, grow and transform

6. Converged Multi-Service Ports
• Applications are moving from private delivery to Internet delivery and vice-versa
• E.g. Office 365 is a movement to SaaS and Internet delivery but with Cloud Connect
via ExpressRoute it is an example of an application flipping between delivery methods
• Internet often needs to breakout locally to maximize Cloud/SaaS performance
• Customer should only worry about total bandwidth needed and let the Converged
Multi-Service Port flex between private and public access of applications
• Usage based billing on the port allows you to pay only for the total b/w you use
• Internet can be secured by our Network based secure web gateway service

What is ‘Hybrid Networking’?
9
Hybrid WANs is where a mixture of Internet and MPLS is used to achieve private networking
Benefits
• Scalability and Cost Efficiencies- Augment the reliable MPLS WAN with lower cost bandwidth
• High Availability- Broadband and/or 4G/LTE cellular diverse backup circuits to achieve higher availability
• Performance- Just like our standard Converged Multi-Service Port (DIA/VPN) it has the ability to provide
local Internet Breakout which is needed to access SaaS based applications e.g. Salesforce

12. Case Study
Customer Challenges:
• 47 sites including 13 countries across Europe, 2 Countries in LATAM, USA, India, Canada, 6 countries in Asia/Pac
• DC and IT consolidation has created the ‘thin branch’ which requires outsourced managed LAN
• Evolving DCs, PBXs (TDM to IP) and changes in branch office locations
• New fast growing online business needed collocating in a high availability DC with ability to grow to high bandwidths
• Video streams & Real-time critical applications need to work globally and want more visibility into these traffic types
Solution:
• Global managed cross regional Managed MPLS/IP VPN with APM (VI) with regional centralised Internet Access in each continent
• Colocation with EVPL connecting DCs
• US and EU Voice Complete (SIP Trunk)
• Managed LAN across all branch sites
Critical Success Factors:
• Global network for MPLS with Colo facilities to host their applications & online business over high bandwidth MPLS & Internet connections
• Converged Global Internet solution with the best in class peering saved them 25% costs over many local internet services
• SIP Trunks allowed them to migrate from TDM to IP based voice seamlessly and with 30% cost saving
• Dedicated Service Manager and 24x7 NOC
• SNMP Events & Managed APM allows the customer to get real-time events on application and VoIP performance and easily perform impact
analysis as they change/evolve their IT infrastructure
• Flexibility to design a solution that meets the business requirements

13. Case Study
Customer Challenges:
• Customer wants to upgrade their retail store customer-facing and internal network infrastructure
• Increasing bandwidth to store locations, enable public Wi-Fi, and linking back-office systems to
their corporate data centres in a cost effective manner were the driving priorities
• Customer was looking for a provider who could provide a reliable, secure in-store connectivity and
deploy it on a very large scale (several thousand locations)
Solution:
• Nationwide managed WAN/LAN solution deployed to over 7,000 locations
• Multi-vendor access connectivity, management of all CPE devices, cloud-based firewall and 4G
wireless back-up
• Public and private Wi-Fi implementation with back-office traffic connected to DCs via dedicated
MPLS connections
Critical Success Factors:
• Management of multiple access vendors in deployment of various access technologies
• Ensuring seamless interoperability across multiple elements comprising in-store hardware
configuration
• Migration and implementation of services to Level 3 as dictated by customer
• Coordination of site surveys and site construction for access services
• Engineering in-store Wi-Fi and wireless failover to ensure optimal coverage and performance
