Broadcom Jericho3 AI Ethernet Fabric

[@louissenderler6866]

Just like Cisco CELL (64byte fixed length) transmiting over GSR FABRIC, Cisco put the scheduler in a LC... this is now the popullar way building DC fabric ( is Google TIN same?).

It appears to me as if Broadcom took a Juniper router from thirty years ago and distributed its line cards and switch fabric cards into leaves and spines.

How do they achieve 10ns convergence times esp when there may be indirect link failures, say, between the egress leaf to spine link? The cells in flight between the ingress leaf to spine will be blackholed as well as any traffic until the ingress leaf realizes the topology change and sends all traffic to the other spine exclusively.

Reminds me of ATM LAN emulation from back in the '90's. VBR anyone? Yes I'm old. 😉

Ha yes, I'm old too.....
