Bandwidth versus Throughput
Naive Question on the Bandwidth versus Throughput
EE Members / Gurus ,
Need your help to clarify the definition
1. If i hear in a meeting , client has internet link of 40Mb . Does this means his bandwidth is 40Mb or the throughput ?
Does this 40Mb in case if it is bandwidth inclusive upload/download speeds ie 20/20
2. What does the terminology means ' ' pipe can handle 80Gb of traffic ' . Does this mean the backbone / backplane speed can or should handle this traffic

Sid

Tip: For more detail about large pipes, call a company like Pair or OVH + talk with a human in their customer support.

One other item to consider which happened here where I work; we have something like 125 Mb download but our external firewall port is 100 ... so we won't benefit from the extra until we physically upgrade the firewall to one with a gig port ...
Only 125Mb download, do you need to get a new cable when there 125Mbits have passed?...
125Mbps is a measure of speed.(amount over time).
125Mb is 125 Mega bits, roughly 12.5 Mega bytes,... or just a very old USB stick of amount of data, no indication of speed.
Obviouly you need to refresh the firewall more often as then is full after 100Mb...

Oops, I may have written it wrong (above) but bottom line is ... our external port won't even support what we are paying for.
Getting units, & scales right is rather important. Esp if they are the ones that get discussed.
And you are right about the mismatch in capacity. The smallest bandwith limits the overall theoretical maximal throughput.
(in practice it will get lower still due to overhead in processing on the firewall.).

Thanks Team for your valuable inputs .
BTW , 80GB it was not a conversation , it was just an example :)
In short ,
Bandwidth is theoretical speed
Throughput is actual speeed ( which can be audited by using tools likes speed test ) , right .
