New Ethernet Standards Reflect Market Evolution, Burgeoning Usage

July 13, 2016 By Steve Senne in

Global standards-setting and industry association Ethernet Alliance recently announced it had approved a string of new IEEE 802.3 Ethernet standards. Approval of IEEE 802.3bp, 802.3bq, 802.3br and 802.3by highlight Ethernet’s relevance and fast growing usage amidst soaring levels of data traffic and heightened threats to network and data security, the non-profit organization highlights in a press release.

The new technical standards illustrate how Ethernet technology is advancing in terms of both scope and scale in light of market trends and demanding new applications, such as in ¨hyperscale¨ data centers and Cloud-based platforms, Internet of Things (IoT) networks, automobiles and transportation, and Power Over Ethernet (PoE), Ethernet Alliance says. 

“Ethernet is erupting in every direction. Whether you’re talking new markets like automotive or historic proving grounds such as networks and data centers,¨ Ethernet Alliance chairman and Huawei senior principal engineer John D’Ambrosia elaborated. ¨

Industry participants’ efforts to expand and enhance the full range of Ethernet’s functionality and features has reached a critical mass, he continued. ¨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.¨ That includes delivering data at speeds of 1 Gbps, 25 Gbps and 40 Gbps. 

¨These new standards are the latest product of the surge in enthusiastic activity permeating the Ethernet ecosystem, but they’re just the tip of the iceberg – there’s much more yet to come. We commend the members of IEEE 802.3 Ethernet Working Group for their efforts and congratulate them on a job well done.”

802.3 Ethernet Standard

Regarding the new standards: 

  • 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 802.3bq, “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 802.3br, “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.
  • 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.
