Help - GbE speed and duplex

Hi,

Can some one please tell me:

- does GbE mean each direction (half-duplex) can transfer 1 Gbit/sec, and
full-duplex can transfer 2 Gbit/sec?
- what wire speed (GByte/sec) is, and is it for half or full duplex?

Thanks,


T.

GbE means that the peak (instantaneous) bit rate on the wire is 1 Gb/s.
I suspect that all GbE NICs can handle GbE FDX, but if there any NICS
which only handle GbE HDX, I'm sure they would be sold as and I think
they would conform to GbE standards.

Neither GbE nor any of the slower Ethernet standards specify any STR
(Sustained Transfer Rate) -- that would be beyond the scope of the
standards, and beyond the control of the NIC designers.
