  2. 2. A Legacy MPLS/IP VPN 2 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 Internet MPLS T1 T1 T1 T1 2xOC3
  3. 3. Enterprise Challenges 3 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. 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 4 SDN, Cloud Connect, Local Internet and Secure Web Gateway Play here
  5. 5. Enterprise Cloud Transformation Private Clouds The WAN needs to be able to securely and flexibly support your digital strategy 5
  6. 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 6 Future proofing branch connectivity as you adopt the Cloud Level 3’s Converged Multi-Service Port MPLS Private Internet
  7. 7. Modernising Your WAN 7 Cloud Connect for predictable & controllable application performance and simplified security MEF2.0 Metro Ethernet modern scalable and resilient access network SDN automatically orchestrates the lifecycle of the service and enables the path to WANaaS Public-Private agnostic connectivity delivers Internet locally to maximise SaaS performance Hybrid WAN & SD WAN support a mix of reliable premium access with lower cost access Ubiquitous Network Based Security enables secure local internet & supports mobility Outsourcing the management allows the organisation to focus on growth and transformation

  9. 9. Hybrid WAN Branch Sites 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 Public & Private Cloud Applications HQ/ Data Center ‘Legacy’ MPLS/IP-VPN WAN Hybrid WAN Public Internet 4G/LTEMPLS/IP-VPN
  10. 10. MPLS IP VPN + Central Internet Breakout Layers of Hybrid WAN Functionality 10 InDevelopment Local Internet Breakout from Converged Multi-Service Port & Secure IPSec Split Tunnel Access MPLS + Internet Active-Active Load-sharing Using Policy Based Routing Security + Performance Based Routing SDN & NFV Functionality, Bandwidth and Policies On-Demand and dynamically optimizing & protecting CPE based dynamic automated path selection Zero touch provisioning for ease and scale Maximizing Investment in secondary access by using it to augment bandwidth rather than just a failover - Includes Broadband resale Improved performance of SaaS services and connect lower grade sites cost effectively with Internet ‘Legacy’ WAN providing the foundation for end-to-end QoS, VoIP + Data & Availability Standard
  11. 11. Case Study Customer Challenges: • Increasing pressure on budgets and staff required a heavily outsourced approach • Increasing demands on data access • Data centre consolidation and growth required a solution that could flex Solution: • End-to-end NaaS (Network as a Service) • Managed MPLS/IP VPN connecting 60 sites • Voice Complete (SIP Trunk) & Managed PBX • Managed LAN including the engineering, design and installation of cabling and equipment, monitoring &management • Managed Wireless LAN Access Points • Managed Video and Audio Conferencing • Managed Firewall and Managed Intrusion Detection/Prevention System Critical Success Factors: • Ability to execute on the complete solution • Flexibility to allow for growth 11 Department of Homeland Security
  12. 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 12 Premier Farnell - A Global Electronics Manufacturer/Distributor Group PLC
  13. 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 13 Starbucks - Coffee Shop Chain Public Internet MPLS Retail Store Level 3 MPLS Access Data Center 1 Data Center 2 MPLS 4G Failover WiFi CPE
