BITS or BYTES
I was looking to get more into the traffic shaping aspects of PFSense. When I run through the wizard, I notice it keeps looking for "Mbits/s", and I'm wondering if I'm misinterpreting this?
So if my internet speed is 200 "Mbps" down and 10 "Mbps" up, and I get this screen and enter 200 for the download, I'm really telling it 200 "Mbits" which is really "25 MB"? Everything is this way.
For example, VOIP...
So if I want to dedicate 1 MB which should be ample for 10 100K voice streams, then I shouldn't add "1" in the "Mbits/s" field, but rather "8 Mbit/s"?
Am I misunderstanding this, or is everything really in BITS instead of BYTES? If so, I'm curious as to why since most people think of their speeds in terms of MB?

Communication line speed is normally specified in bits/s
Prob. inherited from "Old serial comms ... Ie. 9600,N,8;1"
I have never seen a Ie. a xDSL line specified in B/s , only in b/s
Ie. 10Mb/s up , and 100Mb/s down.
Also a for voice codec bw. are specified in b/s Ie. ALAW is 64Kb/s.
I think that specifying any bw related info in b/s feels natural to me.
@bingo600 Thanks for the information…
The abbreviations are still a little confusing for us home users who’ve been conditioned to think of their available speeds in terms of how many megabytes the speed test shows.
So if I want to specify 1 megabyte to the VOIP shaping, for PFSense I have to convert it megabits? Same for the maximum speed of the WAN?
WAN is 200/10 Mbps, so I would enter 1600/80 Mbits/s in PFSense as my speeds on WAN?
VOIP requires 1 Mbps, so enter 8 Mbits/s in PFSense?
Just want to be clear…

I’m not worried about specifying it that way. I just wanted to be sure I entered it correctly. I can do the conversion and enter it in Mbits, I just wanted to be sure that is what PFSense was expecting.
My motivation is that I want to do more tinkering with traffic shaping, and I’m looking to learn a thing or two along the way. I know I can use the wizard to get the basics running, but I want to get more involved in making it customized for my specific situation.
I just wanted to get the measurements straight in my head.
Yeah, I see…. LOL
I guess I always confused the capital MB vs Mb as being the same thing. Thankfully, I paid enough attention to notice before I made the wife upset when things stopped working.
I always say, I know just enough to blow myself up.
