25 Gigabit Ethernet Consortium Becomes to Ethernet Technology Consortium

The 25 Gigabit Ethernet Consortium, originally established to develop 25, 50 and 100 Gbps Ethernet specifications, has announced it has changed its name to the Ethernet Technology Consortium in order to reflect a new focus on higher-speed Ethernet technologies, the company said.

The goal of the consortium is to enhance the Ethernet specification to operate at new speeds by utilizing specifications that are developed or in development. This allows the organization to work alongside other industry groups and standards bodies to adapt Ethernet at a pace that aligns with the rapidly evolving needs of the industry. The ETC has more than 45 members with top-level promoter members that include Arista, Broadcom, Cisco, Dell, Google, Mellanox and Microsoft.

One of the first specifications to be championed by the newly named organization is the 800GBASE-R specification for 800 Gigabit Ethernet (GbE).

The 800 GbE specification introduces a new media access control (MAC) and Physical Coding Sublayer (PCS). It essentially re-purposes two sets of the existing 400GbE logic from the IEEE 802.3bs standard with a few modifications in order to distribute the data across eight 106 Gb/s physical lanes. As the PCS is reused, the standard RS(544, 514) forward error correction is retained, for simple compatibility with existing physical layer specifications.

The Ethernet Technology Consortium is an open organization of networking and data center industry leaders who are enabling the transmission of Ethernet frames between 25 Gbps and 800 Gbps. The consortium also promotes the standardization and improvement of the interfaces for applicable products.
