200 and 400 Gigabit Ethernet solutions are now shipping from an ecosystem of optics and switch vendors - but only the most open of these switches support SONiC today. We will review the use cases for these high speed Open Ethernet switches. Besides raw speed, these new 200/400G switches will bring new telemetry and dynamical routing functionality to SONiC powered data centers. Lastly, we will identify some gotchas to look out for as not all 200/400G switches are created equal. Presented by David Iles.
