Welcome back @SaucisseTelecom !
Keep dropping ✌️
Salut la commu… on est de retour et bien décidé à croquer une part du bon gros gâteau du marché de l’IA. Comme vous pouvez le voir on maîtrise déjà l’IA générative pour faire des belles affiches de m*** qui piquent les yeux, et pas que… 🍩🦔

At 13K views and counting since NANOG 96, this Talk is worth the watch.
Good thing about DDR shortage: this will trigger resources constrained engineering, and software engineers will think twice before malloc(). And maybe, they'll optimize existing code (or maybe not).
How it started: Cisco AGS+, 1990s
How it's going: Cisco 8223-64EF-M, 2026
From 533 Mbps to 51.2 Tbps routers.

I'll be in @nanog next week in SF. Excited to attend the event for the very first time. I'll have the chance to copresent a project I've been working on recently with an amazing architect and customer who #pushdastuff
Let's catch up if you're around #NANOG96
Must read if you're still using legacy features or ciphers.
Cisco IOS XR Resilient Infrastructure, by Luc De Ghein: cisco.com/c/en/us/support/do…
Starting IOS-XR 25.4.1, we're taking actions to deprecate and remove insecure features and ciphers. This is following a phased approach.
Refer to Resilient Infrastructure page for more details.
New on xrdocs.io: IOS XRv 9000 UCS M7 Appliance software upgrade
This article covers both IOS XR and appliance firmware upgrade.

Today in @CiscoIOSXR release notes:
"We have upgraded RSVP-TE to support link bandwidths up to 10 Pbps, essential for integrating high-capacity interfaces."
Second time this week I use Petabits per second (Pbps). We must get used to it, it's real.

Today we announced the Cisco 8223 router, powered by Silicon One P200 ASIC:
- 51.2 Tbps (full duplex), 19.2 Bpps on a standalone chip
- integrated MACsec
- 16GB HBM for deep buffers
- 64x800G ports, including IEEE 800GbE & 800G ZR+ support
- Fits in 3RU only
#pushdastuff
Power your distributed AI clusters with the Cisco 8223 router and experience unmatched performance, deep buffers, and flexible NOS support.

Mikrotik CRS812 DDQ, introducing 400Gbps.
While I won't position it for "AI clusters" as the presenter suggests, it's still quite an achievement and impressive. Kudos @mikrotik_com for the launch.

Cloudflare's defenses have been working overtime. Over the past few weeks, we've autonomously blocked hundreds of hyper-volumetric DDoS attacks, with the largest reaching peaks of 5.1 Bpps and 11.5 Tbps. The 11.5 Tbps attack was a UDP flood that mainly came from Google Cloud. Stay tuned for a full breakdown in our upcoming report.
10th first try ✅

I was lucky again to speak at Cisco Live. What I enjoy in the show are hardware exhibitions and demos. This year we had a 64x800G switch powered by Silicon One G200 (51.2 Tbps) using direct liquid cooling technique
Thank you @JeromeTissieres for the nice gift yesterday during @CiscoIOSXR 8000 techtorial
Great presentation from the legend @petrlapu @_CHINOG_ 12: youtube.com/watch?v=t7d3gTQ6…
Unfortunately he could not cover the last section which is about 100k+ clusters, so we must stick with the slides: chinog.org/wp-content/upload…
