}} Accordingly, at the IEEE Industry Connections Higher Speed Ethernet Consensus group meeting in September 2012, 400 GbE was chosen as the next generation goal. Additional 200 GbE objectives were added in January 2016.

The University of California, Santa Barbara (UCSB) attracted help from Agilent Technologies, Google, Intel, Rockwell Collins, and Verizon Communications to help with research into next generation Ethernet.

As of early 2016, chassis/modular based core router platforms from Cisco, Juniper and other major manufacturers support {{nowrap|400 Gbit/s}} full duplex data rates per slot. One, two and four port 100 GbE and one port 400 GbE line cards are presently available.

= IEEE project objectives =

Like all speeds since 10 Gigabit Ethernet, the standards support only full-duplex operation. Other objectives include:

  1. Preserve the Ethernet frame format utilizing the Ethernet MAC
  2. Preserve minimum and maximum frame size of current Ethernet standard
  3. Support a bit error ratio (BER) of 10−13, which is an improvement over the 10−12 BER that was specified for 10GbE, 40GbE, and 100GbE.
  4. Support for OTN (transport of Ethernet across optical transport networks), and optional support for Energy-Efficient Ethernet (EEE).
