Yes, you can certainly get more than 100mb total throughput, if you add the
two directions together. But you can still only get 100 mb in either
direction, even if there's no traffic in one direction. It's really a
matter of semantics. Marketing types like to add both directions together
and claim that as the bandwidth, because they can claim a higher bandwidth
that way. But in my opinion it's more useful to say it's 100 mb full
duplex, and that tends to still be the standard, particularly for serial
links.

Subject: Re: Full Duplex
So on a full-duplex 100 mb ethernet link you could theoretically get 200
mbps throughput?? I have had this argument with several people before. I
thought that 100 mb each direction being possible, if both parties transmit
at the same time but in different directions, you still have 200 mb of
throughput. They all thought I was crazy - said you can't possibly get
more
than 100 mbps out of a 100 mb link.
