Take a Network Break! This week we start with some FU on Juniper’s Mist AI, the ConnectWise vulnerability, and the 25th anniversary of the Cisco Cat6. The US Cybersecurity & Infrastructure Security Agency (CISA) has proposed new rules that require organizations to report security incidents within 72 hours and ransomware payments within 24 hours. Intel... Read more »
To run AI workloads, a network needs thousands of GPUs and those GPUs must operate in sync. If there is congestion or dropped frames, very expensive efforts could be delayed or disrupted. While there are advantages to using Ethernet for AI networking (including engineers well-trained in the protocol and a robust ecosystem), it wasn’t designed... Read more »
Today Tom, Scott, and Ed discuss the exciting announcement in IPv6 world: Microsoft is expanding its CLAT support in Windows 11. This means enterprises can be even more comfortable transitioning to a IPv6-only network: Now not only do they have DNS64 and NAT64 to translate IPv4 to IPv6, but they have CLAT for any apps...

Take a Network Break! This week we try to peel back the layers on HPE’s announcement about new GenAI capabilties in Aruba Networking Central, parse Broadcom’s touting of its AI credentials, and feel conflicted about Intel sucking up billions in taxpayer dollars. South Korean chipmaker SK Hynix dangles a $4 billion investment promise to the... Read more »
Where there are containers, there is networking. Today we dig into the networking that underlies Kubernetes, the open source orchestration platform for container-based applications. Our guest Karim El Jamali takes us through the essential concepts: Nodes, pods, clusters, CNIs, virtual ethernet pairs, ingress controller, eBPF, and service meshes. As container-based applications grow in popularity, it’s... Read more »
Is WebAssembly (Wasm) here to replace containers? Not really, says guest Matt Butcher. Instead, Wasm is here for a specific kind of workload: One that needs to start super fast (under a millisecond), handle something, and then shutdown. Containers are still best for running very long, I/O intensive multithreaded workloads. Matt, Michael, and Kristina discuss... Read more »
Life isn’t easy for someone looking for a job in tech. There are lots of content mills pushing the idea that if you just pass this one six-month course, you’ll have a six-figure career in no time. There are lots of hiring companies who make job applicants jump through a ton of hoops, but often... Read more »
Welcome to a crossover episode with the Packet Protector podcast! You’re already running IPv6, even if you don’t know it yet.
