NG Ethernet Forum

IEEE is home to Ethernet standardization.
Since 10G Ethernet over copper standardization has been finished in June this year, the IEEE 802.3 Higher Speed Study Group pushed ahead for investigating Ethernet speed beyond 10Gbps physical layer speed.
The natural speed increase in the Ethernet history goes by the order of 10, which leads to 100 gigabit/s Ethernet as a possible next step for Ethernet standardization.
Consequently, you will already find a number of 100G related documents and presentations on the study group public area..
Two important meetings have already taken place in Knoxville (September) and in Dallas (November).

To me it looks as if Finisar is most actively concentrating on 100G optics and Cortina Systems contributes to the MAC layer issues. These are just two examples of a number of 100G supporting companies.
Force10 Networks, however stands out for its clear 100G Ethernet commitment and leading role within the IEEE 802.3 Higher Speed Study Group.
