To complicate things more, doesn't it really transmit at about 125 mbs in
both directions at the physical layer... but with the 4/5 encoding you only
end up seeing 100 mbs being transferred in each direction.

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.

Hi akshay,
If its full duplex you will get 2Mbs of transmit bandwith 2Mbs
of
receive traffic... In a half duplex link you will get a total of 2mbs
for
transmit and receive.
hope the above helps,

The 2Mbps link i had mentioned is a serial link (E1) not an ethernet
link.

Yes. You'll get 2M Transmit 2M REceive(4M) between AB with full
duplex.
With half duplex transfer rate is poor, it is about 1M or less.
You can imply full duplex only with switch, or just host to host
link.
With
hub, you can only use half duplex , because each station must detect
collision before transfer, full duplex doesn't detect
collision(There
is
no
collision with full duplex).
