It is indeed surprisingly hard to draw a simple timeline for ethernet
speed evolution. Network throughput is relative to the medium (fiber
optic, coaxial, twisted pair...), distance (LAN, switch, WAN), number
of channels (half duplex, full duplex), level of commercialization
(research, production, commodity....). All these factors contributed
to different ethernet NIC speeds during the same decade or even year.
My goal was to compare network performances evolution vs CPU
frequency advance in the past and for the next 10 years. It is a lot
easier to show x86 CPU frequency changes on a time chart.

I am preparing a presentation where I will discuss commodity

idea is to show the advance in network interfaces speed over time on
a chart. So far I have collected the following *approximative* data
for Ethernet:
1990 --> 100Mbits/s
2000 --> 1Gbits/s
2010 --> 10Gbits/s
2020 --> 100Gbits/s
FWIW, your ethernet timeline might be a little too long. I could
swear I read an internet trade rag recently that was anticipating
pre-standard 40Gbps ethernet equipment by the end of 2010 (similar
to how you can buy pre-standard 802.11n equipment from a variety of
vendors now). My *guess* is that 100Gbps will follow much less
than 10 years later because there are already carriers today who
need/want/would buy it.
(note: that's totally a guess -- don't read anything into into
based on my email address; I'm in the unified computing/server
group at Cisco -- nowhere near related to the 40/100Gbps groups)
