I am preparing a presentation where I will discuss commodity
interconnects and the evolution of Ethernet and Infiniband NICs. The
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.
Initially, 100 Gb/s Ethernet will be for switch-to-switch links and
will be long before 2020.
The CPU roadmap to handle 100 Gb/s (via PCI-Express, QPI, HT, etc.)
may dictate when NICs will support that rate.
