Learn essential strategies for protecting embedded applications from network traffic overload in this 34-minute conference talk from the Linux Foundation's Open Source Summit. Explore three key approaches to rate limiting network packet ingress: the tc Linux utility (including tc qdisc), eBPF implementation, and Ethernet PHY link speed adjustments. Discover how intentional packet dropping can prevent network broadcast storms and attacks from consuming excessive processor bandwidth on embedded platforms. Watch live demonstrations of each rate limiting technique in action and understand their comparative impacts on system performance. Gain practical insights into minimizing ARM microprocessor bandwidth consumption while maintaining application functionality under high network traffic conditions.
