AI infrastructure conversations tend to be dominated by GPUs, data center buildouts, and power and water consumption. But networks also play a crucial role, whether to support huge file transfers to a compute cluster, stream telemetry from edge locations to feed AI pipelines, or provide high-speed, low latency connectivity for AI agents. On today’s Tech... Read more »
The architecture and tech stack of a Secure Access Service Edge (SASE) solution will influence how the service performs, the robustness of its security controls, and the complexity of its operations. Sponsor Fortinet joins Heavy Networking to make the case that a unified offering, which integrates SD-WAN and SSE from a single vendor, provides a... Read more »

Could an LLM or some kind of an AI-driven language model, such as a natural language interface, someday replace our beloved CLI? That is, instead of needing to understand the syntax of a specific vendor’s CLI, could a language model allow network operators to use plain language to get the information they need or the...
