There is https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/network-plugins/#support-traffic-shaping but that is just on a global pod ingress/egress level and does not support per-destination limits.

thanks for replying. I am not familiar about setting cni. For rke2 using canal cni plugin. Is that meaning I can directly use annotation to limit pod bandwidth or I should install something to my cluster to enable this feature
