    When can Kernel can slow down the backend?

    Network latency in applications is often attributed to user app logic, but sometimes the kernel plays a role. For instance, TCP configurations, such as enabling TCP_NODELAY, can improve network latency. This is because the kernel buffers data to send full-size TCP segments for efficiency, which may delay small data transmissions. Adjusting settings like TCP_NODELAY can reduce these delays and enhance performance for both backend and frontend applications.

    AI Agents in Networking Industry

    AI agents are becoming essential in the networking industry for deploying, configuring, and monitoring networks due to their dynamic and autonomous capabilities. In a demonstrated use case, a multi-agent system consisting of four agents was employed to handle various tasks such as extracting installation steps, executing commands, generating network configurations, and verifying end-to-end connectivity. Although AI agents offer advanced reasoning and adaptability, they also present challenges like increased task completion time and varying output. Smaller AI models are suitable for simple tasks, whereas larger models are needed for complex network designs.
