IEEE Adds Four New Standards for Data Center and Automotive Tech

[Julio Urquidi]

The IEEE 802.3 Ethernet Working Group just ratified four new 802.3 Ethernet standards to meet the demands created from advances in data center, enterprise cloud, and automotive technologies.

IEEE 802.3bq and IEEE 802.3by specifically address data center technologies that require faster throughput needed for today’s hyper-converged cloud/virtual environments, especially when it comes to 25 Gbps (bq and by) and 40 Gbps (by only) Ethernet:

• “IEEE 802.3bq, ‘Standard for Ethernet Amendment: Physical Layer and Management Parameters for 25 Gb/s and 40 Gb/s Operation, Types 25GBASE-T and 40GBASE-T’, opens the door to higher-speed 25 Gb/s and 40 Gb/s twisted pair solutions with auto-negotiation capabilities and Energy Efficient Ethernet (EEE) support for data center applications.”

• “IEEE 802.3by, ‘Standard for Ethernet Amendment: Media Access Control Parameters, Physical Layers and Management Parameters for 25 Gb/s Operation’, introduces cost-optimized 25 Gb/s PHY specifications for single-lane server and switch interconnects for data centers”

IEEE 802.3bp and 802.3br deal with technologies used in industry, but with specific call-outs for automotive networking applications, which in some cases, also falls under IoT in mobile environments:

• “IEEE 802.3bp, ‘IEEE Draft Standard for Ethernet Amendment: Physical Layer Specifications and Management Parameters for 1 Gb/s Operation over a Single Twisted Pair Copper Cable’, defines physical layer (PHY) specifications (including optional single-pair auto-negotiation and Energy Efficient Ethernet) and parameters for full-duplex 1 Gb/s Ethernet operating in harsh environments found in automotive and industrial applications.”

• “IEEE 802.3br, ‘Standard for Ethernet Amendment Specification and Management Parameters for Interspersing Express Traffic’, addresses the needs of industrial control system manufacturers and the automotive market by specifying a pre-emption methodology for time-sensitive traffic.”

i think for automotive industry they should make security standards. Being able to hack a car from the internet is a big safety hazard as it puts lives at risks and also makes it easier to steal your expensive car.
