How Dahua and openEuler’s Kmesh‑bwm Cut Latency 50% and Double Container Density

Facing bandwidth contention when high‑volume video analytics compete with online services, Dahua partnered with the openEuler community to replace the tc htb limiter with an eBPF‑based Kmesh‑bwm solution that introduces lock‑free packet scheduling, directional monitoring and multi‑priority bandwidth guarantees, achieving over 50 % latency reduction, more than 50 % increase in container deployment density, and roughly 30 % overall resource savings.
