Sorell Slaymaker, Principal Analyst at TechVision Research and Amir Zmora, CEO of flexiWAN share their view on the path to SD-WAN, how market requirements change over time and the role of open source in supporting this change. These are the webinar slides. You can access the webinar's video recording here: https://flexiwan.com/webinars/the-role-of-open-source-in-your-sd-wan-strategy/ In this webinar you will learn: - How open source will lead to a de facto SD-WAN standard - Why service providers are choosing to resell multiple SD-WAN vendors in order to service different market segments - How a modular architecture can streamline the service offering across market segments

Is the WAN Market Going Backwards?
• The Hype of SD-WAN
• The Reality of SD-WANs
• Why A Standard is Required
Will Open Source Become the De-Facto SD-
WAN Standard?
• Creating a De-Facto SD-WAN Standard
• Why a SD-WAN Standard is Possible
SD-WAN Market Dynamics & Problem

6. The Hype of SD-WANs
The Promise of SD-WANs BENEFITS of SD-WAN
Optimal Delivery
Across Any
Network
Dynamic
Application Aware
Routing
Centralized
Orchestration &
Management
Faster – Greater Network Performance
Transport agnostic and direct routing to
applications without back-hauling
Better – Simpler & More Reliable
Zero touch provisioning, automation, GUI, analytics
Sub-second re-routing during a “brown-out”
More Secure - Encrypted
Encrypting data in motion, more granular end-to-
end segmentation, network anomaly detection,
zero trust
Cheaper – Best TCO
Service provider agnostic, commodity hardware,
usage-based software licensing, fewer support
resources

7. THE REALITY OF SD-WANS
• Simple
• Consistent
• Reliable
• Cost Effective
• Secure
• Evolution
• “Push Button” Services
• Interoperability
SD-WAN Market
Objectives
No IETF Protocol Standard
• Proprietary solutions
resulting in vendor lock-in
• No interoperability between
SD-WAN solutions – Must go
back to least common
denominator of standard IP
and BGP
• No “one size fits all” solution
• Revolution – rip & replace
Market Reality

8. • Enterprise Networks are a
conglomeration of many sub-
networks that must work end-to-
end
• Each sub-network has different
requirements based on
performance, security, and costs
• Partners, CSPs, M&A, Internet, VPNs
networks need to all interoperate
for the end-to-end quality user
experience, security, and
management
WHY INTEROPERABILITY IS IMPORTANT

9. Is Open Source SD-WAN The Answer?

10. CREATING AN OPEN SOURCE SD-WAN PROTOCOL
01

03
05
Use existing IETF standards
Leverage existing open source
software, libraries, communities
Keep it modular
Offer a turnkey, bundled,
managed/supported solution
Empower Service Providers and
Enterprises to add extensions
for specific requirements
APIs
SD-WAN Technology Stack
Firewall
(Layer 3&4)
NSH
VxLAN
IPsec
IP/BGP

11. • Can provide a pinhole through
a firewall
• Offers 16M segments used in
micro-segmentation for Zero
Trust Security
• Works with existing underlay
L2/3 networks
• Common in many data
centers
VxLAN Example

12. OPEN SOURCE IS THE FUTURE OF SD-WANS?
• Traditional vendors push FUD and will
make path to open source painful
• IP/BGP will continue to be good
enough and SD-WAN will just be used
as a niche solution in the last mile
• New tools will mask the complexities
of networking
• Uses IETF defined protocols – IPsec,
VxLAN, NSH
• Strong market desire for
interoperability and no vendor lock-in
• Zero Trust Networking and SASE will
drive security vendors into SD-WANs
who will use opensource
NoYes

13. SD-WAN IS A CROWDED MARKET

14. Cookie Cutter solutions
Closed solutions
SW & HW bundle
A single vendor lock-in

A THREAT FOR SPs & MSPs

21. Disrupt and Democratize the SD-WAN Market through an
Open Source & Modular Architecture SD-WAN Solution

24. BENEFITS USING FLEXIWAN
50-90% Cheaper
• Reduced SW & HW cost – use what
you need versus the entire bloated,
lower SW licensing cost, lower HW
requirements
• Efficient sales model – freemium,
self-service SaaS model, open source
Removing Vendor Lock-in
Open architecture & open
source
Future proof
Integration of future
technologies (e.g. AI, handling
encrypted traffic, move towards
zero trust networking)
Differentiation
SPs/MSPs/ Enterprises can
offer differentiated services
by Apps, UI, QoS, Security
and have better control over
their SD-WAN service

25. INNOVATION THROUGH BUSINESS MODEL
SaaS Management –
Freemium model similar to
SaaS enterprise products
charging based on actual
usage
Commercial license –
Self-hosting
Transparency: The first SD-WAN company to offer
01 02 03
SaaS
self-service
Pricing

Easy to do
business with

26. STRONG MARKET AWARNESS

27. STRONG MARKET AWARNESS

28. SD-WAN Vendor Environment Is Not Sustainable
• 60+ SD-WAN Vendors
• SD-WAN mostly at the edge of networks,
not in backbones
• Need to fulfill of the promise of SD-WAN
to be agnostic of:
• Hardware
• Transport
• Service Provider
• SD-WAN Software Stack

29. The World’s First Open Source SD-WAN
