Thanks for that. So the interfaces would be pushing data through at the 100Mbps rate but it would be the IFG and the preamble that would reduce actual data throughput. I guess then that frame size would have an affect on the throughput of data as lots of little frames would require more IFGs than a few large frames?
"I am just wondering what the actual throughput rates are that you get on various Ethernet links (10Mpbs, 100Mpbs, 1Gig)
I am not talking about the amount of data in a packet or frame, just raw bitrate... "
They would have 10, 100, 1,000 Mbps, etc., "raw". However . . .
"I guess then that frame size would have an affect on the throughput of data as lots of little frames would require more IFGs than a few large frames? "
Yes, and not just IFG, as Giuseppe noted in his first post, there's other "overhead" that very much impacts the effective throughput of "data" based on the ratio between the two.
The issue of overhead, such as Ethernet frame header (including optionally VLAN tags), also applies to other overhead, such as protocol, e.g. IP (20 bytes) and TCP (20 bytes, plus options), and other media too, when finding effective data throughput vs. media bandwidth.
Consider sending 1 character per IP TCP packet using telnet. If you push the media at maximum, your effective data rate is rather low. (NB: one reason for Naggle's algorithm.)
To increase effective data transfer rate, larger packets are so helpful, it's one of the reasons for "jumbo" Etherent.
