AWS Reinvent Intent-Driven Network Infra: Interesting video about Intent-driven networking in AWS. This is the paper he shows in the presentation. Same note as last year, leaf-spine, pizza boxes, all home made. The development of the SIDR as the control plane for scale. And somehow the talk about UltraCluster for AI (20k+ GPU). Maybe that is related to this collaboration NVIDIA-AWS. Interesting that there is no mention to QoS, he said no oversubscription. In general, everything is high level, and done in-house, and very likely they facing problems that very few companies in the world are facing. Still would be nice to open all those techs (like Google has done – but never for network infra). As well, I think he hits the nail on the head how he defines himself from Network Engineer to Technologist, as at the end of the day, you touch all topics.
Google view after 18 years: Very nice read about the culture shift in the company, from do not evil, to make lots of many at any cost.
GTP-Crawler: Negative thing, you need the pay version of chatgpt. I wonder, If I crawke cisco, juniper and arista, what would be nearly all network knowledge in the planet? If that crawler can get ALL that date.
VimGTP: Very interesting project. I haven’t used it. But thinking aloud, you could use it to interact with sites that dont have API (couriers)? I think with Selenium you can do things like that?
Maia AI: CLoud providers like to be masters of their own destiny so try to build as many things by themselves as possible. So now MS has developed its GPU for AI. It is quite interesting the custom rack they had to built with the sidekick for cooling down the new chips. There are no many figures about the chip (5nm, 105b transistors) to compare with other things in the market.
Reptar: new Intel CPU vulnerability. It looks like is a feature from Ice Lake architecture. It looks like you can crash the cores but no yet take over. Still interesting.
I am not affected 🙂
$ grep fsrm /proc/cpuinfo $
Mellanox with Debian: Interesting how you can install a nearly standard Debian into a Mellanox SN2700 switch.
Vendor Support API: Interesting how Telstra uses Juniper TAC API to handle power supplies replacement. I was surprised that they are able to get the RMA and just try to replace it. If they dont need it, they send it back… That saves time to Telstra for sure. The problem I can see here is when you need to open ticket for inbound/outbound deliveries in the datacenters, that dont have any API at all. If datacenters and big courier companies had API as 1st class citizends, incredible things could happens. Still just being able to have zero-touch replacement for power supplies is a start.
No Packet Behind – AWS: I think until pass the first 30 minutes, there is nothing new that hasnt been published in other NOG meeting between 2022 and 2023. At least the mention the name of the latest fabric, Final Cat. As well, they mention issues with IPv6 deployment.
There are other interesting talks but without video so the pdf only doesnt really give me much (like the AWS live premium talk)
From this blog, I could read an interesting presentation about network performance using satellite services. I guess there are many blogs about the performance of Starlink but this was the first time I read something about it. I was surprised the results were not that good even with the latest version of Startlink (that I didnt know neither)
I checked out this blog note from Google about Falcon. To be honest, I dont really understand the “implementation”. Is it purely software? Does it interact with merchant Ethernet silicon ASICs? There is so much happening trying to get Ethernet similar to Infiniband that I am wonder how this fits outside Google infra. At the end of the day, Ethernet has been successful because everybody could use it for nearly anything. Just my opinion.
