AI Networks – Driving Ethernet’s Evolution to 400 Gb/s Signaling and 3.2 TbE
The IEEE P802.3dj 200 Gb/s, 400 Gb/s, 800 Gb/s, and 1.6 Tb/s Ethernet project is developing 200 Gb/s electrical and optical signaling and shifting Ethernet’s latest “highest speed” from 800 GbE to 1.6 TbE. As industry considers the deployment of the various specifications that this standard will introduce, the rapid expansion of AI scale-up and scale-out networks has raised the question of the next evolution of Ethernet, based on 400 Gb/s electrical and optical signaling, as well as 3.2 TbE.
This session will provide an overview of the IEEE P802.3dj project and how it is setting the stage for the future evolution of Ethernet. It will also explore current activities within IEEE 802.3 that are anticipated will set the stage for future projects to address the needs of AI networks.
