Enterprise WAN Background
▪ Business applications such as ERP, Citrix, VoIP,
Video NEED Predictable and quality network
services
▪ Secure & Seamless Connectivity among Multiple
branch offices NEED Enterprise WAN / VPN
▪ Subscribe to MPLS VPNs / Leased Lines from
telcos for Performance & Security with SLA
▪ Financial impact of poor WAN quality or Dow
time more in Consumer businesses or org. that
deal with higher volume of transactions.
Enterprises use average of 464 apps including critical apps (source: Cloud Security Alliance)
Cloud & IoT disrupting Enterprise WAN
Current Enterprises MPLS WAN architecture not suitable for the new world
▪ Business Continuity Poor Network quality (Last mile) & ineffective backup
▪ Economics @ branch Inefficient and costly (10x expensive than Broadband)
▪ Application User Experience
Due to lower Bandwidth and utilization
▪ Deployment Complexity Multiple Link types & SLA
▪ Agility & Manageability
Traffic @ 30% YoY growth

SD-WAN Controller / Orchestrator
SD-WAN leverages multiple active WAN links / Paths and delivers secure & superior
connectivity between branches/DC/Cloud through directly programming data plane
▪ SDN• Agile delivery of network services at Hyper-scale - both in BW and Reach
• Technology & Architecture
• Core use cases: DC, Cloud, telco networks -- Core & Edge Routers
▪ SD-WAN• Delivery of hugely improved & predictable network performance & uptime
• Leverages multiple and diverse WAN Links ( Wireline, 4G etc)
• Tightly integrated with Network Security: Firewall & Encrypted tunnels
• Core use cases: Branch offices, DC & Cloud - Edge Routers

Features Top Customer Use cases
▪ SD-WAN has become mainstream in US and other developed countries
SD-WAN Technology Adoption
▪ India in Early in Early Adopters stage - possible Chasm for Midmarket/ SMB• HW capex for uCPE is high
• MPLS vs Broadband – relatively lower pricing gap compared globally
• Perceived SD-WAN complexity, customization and Lack of skilled resources
Source: Crossing the Chasm, Geoffrey Moore
▪ SD-WAN uCPE Hardware - currently expensive• Need support a variety interface type options
•
▪ Security and Performance concerns in migration from fully MPLS WAN
▪ NFV Consolidation - Ability to integrate & support variety of VNF & PNF
▪ Standardization & interoperability• Compliance to MEF and other industry standards
▪ Faster Delivery models • Standardised Config templates
• Intent based Networking
▪ 4G based SD-WAN for higher reach
Product & Delivery - Challenges & Way Ahead
SD-WAN has the power to transform organizations to be nimbler and fully digital by
providing secure and resilient connectivity ubiquitously
