Re: 10Gbit Ethernet Half-Duplex |

Rich,
I hope you agree that this is a very minor comment. From
what I have read on this and other newsgroups your work
seems to me to be utterly outstanding.
Rich says:
"A switching hub will
always cost more than a repeater hub (on a per-port basis), however,
over time the difference shrinks considerably with competition and
availability of high-integration silicon switching components"
As far as I know (which is not far at all) the cost of LSI components
is strongly related to the production volume and is much less closely
related to the complexity of the chips (until the yield falls off
anyway).
So:-
I contend that your comment "A switching hub
will always cost more than a repeater hub"
is only the case for equal production volumes
and since GBE repeater hubs are practically non
existent, your comment is not strictly applicable.
It would clearly be applicable if neither switching
hubs nor repeater hubs were yet in production.
I have only made this comment since I was hoping for a
second edition:)
Thanks. |

Which was the case in the emerging market for Gigabit Ethernet (which, I
believe, was the context for the statement); of course, you are correct
that I am assuming at least comparable, if not equal, volumes.

Not likely to happen anytime soon, I am sorry to say. My work has taken
a very different direction.

That's too bad (the book part, not your work part! :)
It's hard to find good technical books.
