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
