The IEEE has been busy lately working on all manner of new Ethernet specifications and today four of those new efforts have been formally ratified. The four new standards include, IEEE 802.3bp, IEEE 802.3bq, IEEE 802.3br, and IEEE 802.3by.
Two of the four standards are intended to help define and standardize 25 Gigabit Ethernet. IEEE 802.3bq is titled, ‘Standard for Ethernet Amendment: Physical Layer and Management Parameters for 25 Gb/s and 40 Gb/s Operation’ while 802.3by is titled, ‘Standard for Ethernet Amendment: Media Access Control Parameters, Physical Layers and Management Parameters for 25 Gb/s Operation.”
The new 802.3bp is aimed at automotive applications and will enable 1 Gb/s Operation over a Single Twisted Pair Copper Cable. 802.3br also has automotive industry impact and is intended to help with time-sensitive traffic.
“Whether you’re talking new markets like automotive or historic proving grounds such as networks and data centers, Ethernet’s ongoing expansion has reached critical mass,” John D’Ambrosia, chairman, Ethernet Alliance; and senior principal engineer, Huawei said in a statement. “There’s growing velocity behind work being done to develop the next generation of speeds, innovative technologies, and forward-looking specifications for emerging application spaces.”
The move to create the new 25 Gbps Ethernet speed first got underway in July 2014, with the formation of the 25 Gigabit Ethernet Consortium.
Though 25 Gigabit Ethernet is only now becoming an official standard, multiple vendors already have technologies in market. Among the early adopter of 25 GbE is Broadcom which announced back in 2014 that its StrataXGS Tomahawk silicon would support 25 GbE. In 2015, Arista announced its lineup of 25 GbE switches. Cisco is also embedding 25 GbE support in some of its switches including the Nexus 9516 switch which was first announced in March.
In a 2015 report , IHS Infonetics forecasted that 25 GbE port shipments will represent nine percent of all ports shipped globally by 2019.
