Terabit Ethernet

Terabit Ethernet or TbE describes a possible speed of Ethernet above 100 Gigabit Ethernet. Facebook and Google, among other companies, have expressed a need for TbE.[1] Some think that 400 Gigabit Ethernet is a more practical goal.[2] In 2011 researchers predicted Terabit Ethernet in 2015, and 100 Terabit Ethernet by 2020.[3] UCSB attracted help from Agilent Technologies, Google, Intel, Rockwell Collins, and Verizon Communications to help with the research.[4]

The IEEE announced the formation of "IEEE 802.3 Industry Connections Ethernet Bandwidth Assessment Ad Hoc," to investigate the business needs for short and long term bandwidth requirements. They planned to formally announce reports of findings the first half of 2012.[5][6]

IEEE 802.3's "400 Gb/s Ethernet Study Group" started working on the 400 Gbit/s generation standard in March 2013.[7] Results are expected by 2017.[8]
