RE: Actions and Issues from June Meeting


Good point.  I will derive an equation including packet length as one of the
parameters which affects the BER.

It strikes me that the issue of larger maximum packet sizes will likely
come up, just as it did for GbE.  If 10GbE goes to 9 KB packets, the design
center BER would need to go to 10^-13 to maintain the same theoretical
packet loss rate.   I'm not sure how much effect this would have in
practice, as most gigabit links achieve much better than 10^-12, if they
work at all.  Anyway, these items are ripe for debate and decision.
