I still like to follow what is happening IEEE is doing on Ethernet standardization, although there has been around 10 years since I last time was part of the process. I was participating in Ethernet in the first mile (EFM) standardization work at years 2000-2001 (at that time I worked for Nokia).
There is always something new coming. Now IEEE Seeks Data On Ethernet Bandwidth Needs. The IEEE has formed a group to assess demand for a faster form of Ethernet, taking the first step toward what could become a Terabit Ethernet standard. This time around, the information gathered may help the next high-speed Ethernet group decide whether to aim for 1T bps or 400G bps. There are much more significant challenges involved in achieving Terabit Ethernet than there are in 400G bps. The ad hoc group has met a few times since late February.
There is also push is on to cut 100G Ethernet’s price. Less than a year after 100-Gigabit Ethernet was standardized, an industry group is considering a set of specifications that might make the high-speed technology less expensive and more useful. The IEEE 802.3 100-Gigabit Backplane and Copper Cable Study Group of the IEEE try to make it easier to build modules with more 100GE ports. The effort to develop specifications for 100GE backplanes and narrow cable interface. Standardization of the backplane should help 100GE move beyond proprietary designs and create a larger ecosystem of component vendors.
