Router chart numbers

[deadline546]

Hey this may seem like a stupid question but here it goes

I know connection speeds eg "10m"=1mbs , "100m"=10mbs and "1000m"=100mbs of actual throughput

So with say my adsl2+ connection which is about "11.5m"=1.1mbs actual thoughput (this i have tested). Not that any router cant handle that!

But which number am i comparing against the router charts the connection speed or the actual throughput.

From what i have found it seems to be eg 100/5 mb FTTH would need 105mb+ routing throughput.

Very confusing since it doesn't make sense that the connection speed=required router "throughput" and not connection actual throughput= required router "throughput"

Can anyone explain and or correct me with this i am VERY confused!

Thanks
Marty

Yes, you are confused. It's best to follow the conventions when talking about speed:
Little "b" is bits; big B is Bytes. 8 bits in a Byte.

"10m/100m/1000m" are all ambiguous.

When you see Mbps anywhere on SmallNetBuilder, that means Mega bits per second.

When you see MB/s that means Mega Bytes per second.

There are plenty of routers with > 100 Mbps routing speed.

ok ill try again, If I'm sitting right on top of an adsl2+ 24mb capable exchange which obviously has full speed adsl2+ running at is capable 24mb because it is next door to exchange.

From my understanding 24mb doesn't actually mean 24mbs but usually u divide that number by 10 =2.4mbs and that is the actual say max "download speed" for example when i live very close to exchange at another house we had a line speed of like over 20mb but only had a max download speed of about 2.1mbs (which is what my dl program is telling me when i dl something)

Which i may be mistaken but i thought 24mb/10="2.4mbs" was the ACTUAL max throughput not 24mb that they advertise of an adsl2+ connection.

So what I'm asking is which number do they go of for charts "my understanding" of actual throughput from above ?

24mb adsl2+ next to exchange get a 24mb capable router OR get a 2.4mb capable router.

and yes i know most router can handle this Im just trying to understand it!

thanks

Please use Mbps or MB/s. I don't know whether you are talking bits or bytes.

Actually don't worry i work it out!

An adsl2+ connection is 24.0 Mbit/s not MB/s as i was getting confused with so i can directly be applied to smallnetbuilder charts!

Thanks

There are 8 bits in 1 byte, so if your transfer speeds are 12 megabits per second, you're really getting 1.5 megabytes per second (12 divided by 8) for example. Some programs report back in bytes, some in bits, it's a matter of which program you're using.
