Determining minimum bandwidth IoT (IPv4) devices need with 4200?
-
Hello Everyone,
We have customers who need to know the minimum bandwidth our IoT (IPv4) devices need in order to work properly. This will allow the customers to determine if they need to upgrade their network links and to what, without wasting money.
I am trying to learn what those numbers are - minimum download bandwidth needed and minimum upload bandwidth needed. I am trying to determine this with a Netgate 4200.
I want to turn off all the bandwidth improvement help the 4200 is trying to provide in order to, as closely as possble, mimic what the customers have - a plain-Jane WAN setup. For example (not an exhaustive list), I want to be able to turn off all Queue Management Algorithm and Schedular settings and change just the bandwidth number on the Firewall -> Traffic Shaper -> Limiters page until test results in our labs converge on the answers.
Does anyone have any recommendations on 4200 settings that will make this happen?
Can I turn off all Queue Management, for example?
Another problem: how can I relate or map the bandwidth settings in the Netgate 4200 back to test results of widely available free (or open source) tools that the customer can use to determine their current bandwidth?
How can I confirm (with tools and tests) matching bandwidth numbers the 4200 has in the settings? I need to be able to confirm and show with non-4200 source code how and why the numbers match.
Help, please.

@Joe0x7F You can delete the traffic shaping /limiters that have been set up…?
Are you trying to determine minimum effective speed or bandwidth used over time?

Hi Steve,
Thanks for your reply.
When I go to Spectrum.com, their current perpetually-in-promo pricing is this:
For their “100 Mbps Internet”, it will cost me $30/month *for 1 year.
For their “500 Mbps Internet”, it will cost me $50/month *for 1 year.
For their “1 Gig Internet”, it will cost me $70/month *for 1 year.
If my customer has 500 of our IoT devices that have to send data back and forth over that link, which Always-Temporary-Spectrum price should I recommend my customer buy?
AND,
Whichever one my customer buys, how will I answer the question (with data), "OK, then how many of your IoT devices will work on this?"

@Joe0x7F so you don't know how much your devices transfer? Devices you make? Also those plans - are they symmetrical? I doubt you get that same speed up if its some cable internet connection.

"so you don't know how much your devices transfer? Devices you make?"
I don't have time to answer naive, inexperienced questions.
"I doubt you get that same speed up if its some cable internet connection."
You don't say?

@Joe0x7F well have a nice day then..

Netgate offers both support plans and professional services to assist with official hardware (i.e. your 4200's) configuration.
The official documentation is also a good reference point.

For their “1 Gig Internet”,
Since Spectrum is a cable internet company you can bet that even with the 1Gig down package you are not getting any more than 50mbps up. (possible but not much more) Since most IOT devices I am familiar with are the cameras I use that would be your limitation if your customer was in fact using cameras as well. Otherwise anyone here is just guessing.
The 100mbps speeds according to the Spectrum website only gets you 10mb up. You are not going to have any issues with the capacity of Netgate routers with these low upload speeds .. you will most likely have more issues with all the noise on a network with 500+ devices if you don't segregate your traffic behind different subnets.
Spectrum likes to give out modems with Puma6 chipsets the last time I worked with one of their customers.. That particular chipset goes to hell when UDP traffic begins to rise.. such as that used by a VPN connection or two.. IP phones ect.

@tinfoilmatt Thanks for the pointers. I'll do the best I can with what you have given me.

@chpalmer Thanks for your experience and thoughts. Good points all.
