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

IT moving towards ITaaS model

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

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

Future proofing branch connectivity as you adopt the Cloud

Hybrid WAN Branch Sites

What is ‘Hybrid Networking’?

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

Department of Homeland Security

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

Premier Farnell - A Global Electronics Manufacturer/Distributor Group PLC

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
