SD-WAN
Software-Defined WAN (SD-WAN) is the second “software-defined” marketing attempt (after the original SDN) to dress a conglomerate of old technologies into shiny new clothes. Even Wikipedia article promotes some of the usual software-defined hype, quoting Network World claim that:
SD-WAN simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism. This concept is similar to how software-defined networking implements virtualization technology to improve data center management and operation.
Is It Real?
Want to know how real those claims are? Start the journey with this series of myth-busting blog posts:
- Software-Defined WAN:Well-Orchestrated Duct Tape? (2015)
- Routing Protocols and SD-WAN: Apples and Furbies (2015)
- Do Enterprises Need MPLS? (2016)

- Lock-In and SD-WAN: a Match Made in Heaven (2019)
- Impact of Controller Failures in Software-Defined Networks (2019)
- Fast Failover in SD-WAN Networks (2020)
Does SD-WAN make sense? Sure:

I covered the basics of SD-WAN in Choose the Optimal VPN Service and SDN Use Cases webinars.
Pradosh Mohapatra described the basics of SD-WAN and its typical components and architectures:

Real-Life SD-WAN
SD-WAN sounds great, but does it work as expected? Maybe not:
- SDN, SD-WAN and FCoE on Gartner Networking Hype Cycle (2015)
- SD-WAN Reality Gap (2019)
- Real-Life SD-WAN Experience (2019)
- Worth Reading: SD-WAN Scalability Challenges (2020)
- Feedback from Another SD-WAN Fan (2020)
Is it secure? Some products seem to be nothing more than a bunch of open-source component glued together with clueless Python code:
- Security Aspects of SD-WAN Solutions (2018)
- SD-WAN Security Under the Hood (2019)
- SD-WAN Security: A Product Liability Insurance Law Would Certainly Help (2020)
- Another SD-WAN Security SNAFU: SQL Injections in Cisco SD-WAN Admin Interface (2021)
Some service providers want to use SD-WAN to offer managed services. Not surprisingly, some people1 don’t find that a good idea:
- SD-WAN: A Service Provider Perspective (2020)
- Managed SD-WAN Services (2022)
- Challenges of Managed SD-WAN Services (2022)
Then there are some technical details vendors love to gloss over:

- Topology- and Congestion-Driven Load Balancing (2021)
Does it work within a public cloud? Yeah, sort of… with a few challenges:
