I’ve had too many people tell me that SDWAN over consumer broadband cannot work. This thread on reddit highlights that it can.
- They ditched their MPLS provider completely.
- Hired a telecoms broker to manage the broadband billing (which no one seems to think of)
- Have visibility and analytics that they never had before.
- Does not require advanced skills to manage.
Here are some highlights from the thread:
So my company went SD-WAN. Over 100+ sites. We totally did a non-renew on our L3VPN service with our provider, a Tier 1 Carrier, and went with a much smaller broker to get all residential grade broadband (cable and dsl) at our branches. It took a little under a year to complete this enormous undertaking (nearly every branch needed buildout to get coax.)
We are now running on Silverpeak with broadband connections and some LTE sprinkled in.
In the short term, it’s been awesome. We log into a portal and manage our whole wan from there. We get all kinds of statistics that traditional routers just couldn’t give us… like end to end loss, latency, jitter, and out of order packet rates on individual tunnels. We also enjoy the little proprietary tricks it does for us like moving packets down the path of least jitter, forward error correction, etc.
The central management and orchestration with templates is probably the biggest boon though, and the biggest paradigm shift over managing 100 routers using stuff like solarwinds and python scripts. The orchestrator portal is just a one stop shop for every single operations, administration and maintenance action for anything WAN related.
I believe that the majority of branch networks can be replaced with SDWAN on consumer-grade internet. Yes, there are exceptions that might need some extra design but best practice is not using MPLS services from a telco.
Project was driven by cost savings, not features:
I’m not the bean counter. I’m the network engineer. At my company they don’t involve us in the bean counting at all. Like, I literally haven’t seen pricing for any of this. I know they paid up front for 3 years, and I know it wasn’t cheap. That’s all I know though. I have to assume the annual recurring cost is still far cheaper, since management pushed this change for cost savings exclusively.
Running a call centre over SDWAN:
We absolutely are running a call center over it. You can believe me or not. The Forward Error Correction, Jitter Buffering, and for voip traffic class, “packets duplicated out all pipes” aka “sd-wan magic” smooths out a ton of issues.
