Urgent Help Needed!
LOL I always wanted to start a thread with that title...

Anyhow - I have a big problem. I need a way to explain Bandwidth - Throughput to Morons. I'm looking for pictures or analogies.

Small words, of course as the audience is comprised of Corporate Executives with attention spans of a small child.

http://upload.wikimedia.org/wikipedi...a594ae8002.png Where Tr is the 10% to 90% rise time, and K is a constant of proportionality related to the pulse shape, equal to 0.35 for exponential rise, and 0.338 for Gaussian rise.

Won't work

T = S / P

Won't work

Even this is too much - they won't understand. http://learn-networking.com/network-...and-throughput

So to sum up. Anyone have any pictures or analogies that correctly explain bandwidth? Please stay away from Latency and the different types of Throughput.

Thanks

Thanks Shay - still too detailed.

bandwidth throughput
explain bandwidth
how does bandwidth work
bandwidth

I'm thinking of trying to use an express way and maybe an on ramp as a visual representation, but It's just not right???

Search google for bandwidth hoses. Should be the second link. For some reason, AO won't let me post the actual link here.

Westin is on a good track. The way I've explained bandwidth, it's a kitchen sink.

If they can't get that well.... /facepalm

Bandwidth is like the kitchen sink.

What goes out the drain is what you can upload.

Well see I kinda screwed up.

It was late one day, I was cranky (go figure) and someone asked me why email and the Internet were so slow. I said because some moron saturated the pipe by sending a global email at the end of the day with a 6.5 MB attachment.

(Of course all 250+ users went to open the attachment at the same time).

Anyway, the next day everyone wanted to become an expert on bandwidth. Some even had Brother in Laws who were experts and would get the information from them.

Best I can gather is the overall belief now is that Bandwidth doesn't matter because the Throughput is really the cause for slow networks and that I have no control over Throughput.

Now because of that insanely stupid statement, I don't get my new 20MB pipe.

BUT IF I HAD PICTURES! (perhaps drawn in crayon) I could change their minds.

To summarize this youtube example. throughput is a 4 lane high way inside bandwidth.
Less bandwidth = less throughput (less lanes for the traffic to travel)

just have to love those family experts :rolleyes:

Hmmmmm............I just remembered where my box of brightly coloured crayons is :D

It's like you own a supermarket with a parking lot of 100 spaces.

Most times that works; but on Friday night, when everyone has been paid, they come to shop................ the first 100 are OK, but the rest can't get in.

1. I can limit your stay to 10 minutes then kick you out.

2. I can only allow the first 100, for as long as they stay in the mall, even though they are shopping at other stores.

3. I can extend the parking lot.

The lot size is the bandwidth, and the number of customers served is the throughput.

"Bandwidth" = "Capacity at any point in time"
"Throughput" = "Quantity served over time"

Otherwise?:
