Re: Issues concerning 10GbE speed standards


I am sadden by your comment that would rather have not worked on 100VG, it you had
known that 100BT would win the majority of the market space.  Engineers should be
willing to work on things that don't make it in the market space.  Look a Thomas
Edison and the phonograph.  If he had known that his solution would not make it
the market place, and had not developed to the point that he had, we would not
have had recorded sounds for long time after.  Sometimes it takes different
choices between technical innovations for the technical people to really
understand what the non-technical consumer really can understand and want.  If
technical people already knew everything, what would be there to learn? Think that
a limited number of alternative PHY solutions will allow the market to define its
understanding and needs as this technology progresses.  Having a predefined,
limited solution stifles innovation.  Let innovation and the market place define
the final solution.

Note: there are still a lot of Token Ring systems out there that are migrating to
Ethernet.  100VG is still a viable solution for some implementations.

Thank you,
