Big thanks to Cisco for Sponsoring this video. For more information about the topic being discussed follow the following link: https://blogs.cisco.com/news/the-thir... 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 If you found this useful, hit subscribe and share with your favorite network nerd.

#513: Is your WiFi or Internet slow? This can fix it.

Big thanks to Juniper for sponsoring this video. To try Juniper Mist please click on the following link: http://juniper.net/trymistyourself Choppy Zoom calls? Random outages? In this demo with David Bombal and Juniper Networks, you’ll see AI that actually helps: a tunnel-free setup for faster failover and a natural-language chatbot that pinpoints the real issue, client, Wi-Fi, switch, WAN, or cloud—and auto-captures the packets you need. We also show simple security defaults (deny-by-default) and why double-encrypting traffic can slow you down. What you’ll learn: Why “old-school VPN tunnels” add overhead—and how tunnel-free can speed things up How a chatbot (Marvis) finds root causes and triggers packet captures at the moment of failure Easy checks for Zoom/Teams quality (latency, jitter, loss) and what to do when it’s not “the Wi-Fi” Off-hours synthetic tests that catch issues before your day starts Practical security: sensible defaults and where SASE fits if you want it // Justin Melloni’s SOCIALS // LinkedIn: / justin-melloni-54b24a1b // Andre du Iuri SOCIALS // LinkedIn: / andre-de-iuri-578391210 // David's SOCIAL // Discord: discord.com/invite/usKSyzb Twitter: www.twitter.com/davidbombal Instagram: www.instagram.com/davidbombal LinkedIn: www.linkedin.com/in/davidbombal Facebook: www.facebook.com/davidbombal.co TikTok: tiktok.com/@davidbombal YouTube: / @davidbombal Spotify: open.spotify.com/show/3f6k6gE...
