OH yeah, such a bad idea. Just a VPN that you don't control and pay a fortune for.
SDWAN is a hell of a lot more than VPN tunnels...
- Link bonding. Mix MPLS/Cable/T1/4G etc.
- Per packet routing. Have the same session use multiple links depending on requirements...
- Jitter management for the above. Can strategically use buffer bloat to make 2 similar segments match on one way latency (Inflate the lower link to match the higher one). This reduces the need for packet re-odrering (expensive from a compute basis).
- Per segment monitoring. Latency isn't symmetric. Using things like 2 party clock synchronization and packet tagging you can measure with packet stamps in real time the one way latency of a link (Critical to keep jitter under control).
- Automated rules engines with multiple factors that can even handle encrypted. Massive centrally collected rules engines based on destination IP, Ports, CNAME on SSL Cert for encrypted, packet headers if not encrypted etc.
- Packet loss mitigation. For bulk media store and re-forward to avoid TCP retransmits keep throughput up. More sensitive real time protocols that are narrower can benefit from duel transmit (send packet down both links) as well as parity injected into packet streams.
None of those things are SD-WAN. Those things CAN be, but they CAN be part of non-SD-WAN too. A VPN can be required to do all of that. These kinds of assumptions are bad, because people get expectations of a technology that does not imply them.
Bullshit. Those things all together are what makes it SD-WAN instead of some random guy trying to say all of his Ubiquiti ERLs with IPSEC tunnels are SD-WAN, because they are not.
@StorageNinja is exactly right on this.

@StorageNinja is exactly right on this.SD-WAN in general simplifies management at large scale (and nore than just the devices, but also the links), optimizies performance in ways BGP, Shaping DSCP alone can't (and with a 1000x less work, no need for bespoke optimizations), enables unlimited choice on the WAN links without unlimited management hell as you try to deal with 10 different CLEC providers, and brings costs down for CPE gear (Virtualized, x86 rather than proprietary ASICs).

Nope. SD-WAN exists without any of those. And I never said that they were. But SD-WAN existed and was standard before anyone associated these things with them. This is like claiming you need all of the things in a UTM to be a firewall.
Lots of SD-WAN products don't offer these features.

These might be common features of a certain type of SD-WAN, but come from things outside of the SD-WAN itself. It's like confusing an implementation with the concept. If you look at Windows, you might think that an OS means a GUI because a few major implementations tie the two together, but that woudl be wrong because DOS didn't have a GUI but was an OS.

From Wikipedia: "SD-WAN is an acronym for software-defined networking in a wide area network (WAN). An SD-WAN simplifies the management and operation of a WAN by decoupling (separating) 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."
Notice that what it IS does not guarantee or even suggest any of those things. You are working form revisionist marketing material and not what an SD-WAN actually is. Very dangerous because it makes it trivial for salesman to sell you an SD-WAN with you thinking that they sold you all this stuff, and get nothing. And they did nothing wrong, because they were being honest.

Or keep reading the wikipedia article and see that I was largely describing the feature section....
I'll argue it's pedantic to try to separate SD-WAN from Hybrid-WAN at this point as (the majority) of deployments of SD-WAN will be Hybrid-WAN. Wayyyyy to much of IT spend in companies is telco's, and the combined technologies are going to do what virutaliation in x86 did to compute, and what HCI and cloud is doing to storage.

To get the topic somewhat back on the rails, @bbigford I have enjoyed working with Juniper. They have at least feature equivalence with Cisco and a significantly better engineered OS (based on FreeBSD). Their pricing is significantly better than Cisco (although not in the same range as Ubiquiti).

Yes, but you were describing possible features as defining characteristics which are wholly different things. That's how sales people trick customers all the time. Customer things X means Y, sales people know this is a common misconception, they promise X knowing the customers wants Y, customer is at fault for buying the wrong thing.
UTM and SAN are famously sold this way.

EVIL SALES GUY TRICK #403. DESCRIBE WHAT THE BENEFIT OF A PRODUCT RATHER THAN SIMPLY USE A VAGUE BUZZWORD
If you Limit SD-WAN to just being "a separate control mechanism" then some Cisco stuff from the 90's falls under than and it's a meaningless term.

It still has to be software defined, though. It's a broad term without a lot of purpose, but it is what it is. Just like software defined anything, is very broad. But being software defined is an extremely logical concept to name something, and having something that is software defined not be included because it doesn't do an arbitrary set of features doesn't make sense.

Most "hot new things" apply to existing technology. It's extremely rare that a new industry term arises before (or with) the invention of something. It's normally more a recognition of something that's been created. SaaS for example arose as a term decades after the idea was pioneered and at least five years after it was mainstream. But it doesn't make the things that predate the name not SaaS, it's just a super broad term.
