Cisco’s Martin Lund joins David Bombal to unpack how AI-scale networking really works - and why a 51.2 Tbps, 64×800G, post-quantum–ready router matters. We break down scale-up vs scale-out vs scale-across, deep buffers to prevent drops on long-haul links, line-rate IPsec/MACsec, SONiC vs IOS XR, P4 programmability, coherent optics for ~1000 km DCI, and how these pieces enable exabit-class fabrics for AI clusters.

What you’ll learn

• Why GPUs are useless without massive, reliable interconnects

• 51.2 Tbps with 64×800G ports and what that enables for AI training

• Deep buffers vs shallow buffers and when each wins

• Line-rate encryption today and post-quantum readiness tomorrow

• SONiC on Cisco Silicon One, P4, and automation at hyperscale
