The following info is cut and paste from several emails to Gigabit Ethernet Alliance in an attempt to clear up the 10 Gigabit Ethernet picture. From this person Bob Grow the information is he has not heard of the 10GbE connection being deployed, but GbE has been deployed on a 1000km Canadian network. The supplemental info on the standards and interoperability is germane and timely, and may help some of us make some decisions re the FC (fibre channel) issue and NAS // SAN market development.

I know of no deployment of Ethernet running at this speed. A standards development project is expected to be approved at the January 2000 NESCOM meeting. Like Gigabit Ethernet, the standard would be a suppliment to the base IEEE 802.3 document that includes specifications for all speeds of ethernet operation. Presentions and minutes of the study group are available from the IEEE 802.3 home page:grouper.ieee.org . Bob Grow Vice Chair, Technical Liaison Gigabit Ethernet Alliance > > >
