Podcast EP351: A Detailed Overview of the Emerging Standards for 400G with Kent Lusted
Daniel is joined by Kent Lusted, a Distinguished Architect at Synopsys and an integral part of the company’s Ethernet IP design team. He has been an active contributor and member of the IEEE 802.3 Ethernet PHY standards development leadership team for more than 15 years. Prior to Synopsys, Kent worked at Intel for 30+ years, focused on designing Ethernet board products and performing Ethernet interop debug all over the world. Kent is currently the electrical track chair for the IEEE P802.3dj Task Force and Chair of the IEEE 802.3 400Gb signaling study group.
In this very informative discussion, Kent and Dan explore the emerging standards work that will enable 400G communications. Kent describes in detail the various stages that standards development go through to get from early specs and requirements to the robust details that facilitate successful production deployment. The 400G standards effort is in its very early stages. Kent explains that the prior 200G standards work is still not complete, so the 400G effort is indeed in its early stages.
That said, he points out that 400G speeds will be critical for the requirements of emerging scale-up and scale-out AI workloads. Kent describes the meaningful work design teams can engage in now to ensure a smoother path to implementation later. There is a lot of very useful information conveyed regarding how to build advanced systems, how to engage with and leverage standards efforts and how to use Synopsys’s substantial resources to move designs forward.
