Network QoS Support for Kubernetes Applications - Jun Du, Huawei

Network QoS Support for Kubernetes Applications - Traffic shaping is one of the important aspects in network QoS. In Kubernetes, traffic shaping for applications will happen if bandwidth-related annotations have been added to the Pod's metadata. This presentation will show our implementation that adds a simple CNI plugin using the linux tc to create an ingress(include burst) and egress(include burst) rate limiters. We have already contributed the CNI plugin to CNI community and the integration work with Kubernetes leading by Kubernetes SIG Network is in progress.

Network QoS Support for Kubernetes Applications - Jun Du, Huawei

Traffic shaping is one of the important aspects in network QoS and it's widely used in many scenarios where you want to control traffic. In Kubernetes, traffic shaping for applications will happen if bandwidth-related annotations have been added to the Pod's metadata. However, currently only kubenet supports applying basic traffic shaping during pod setup while kubelet doesn't support it when it runs in CNI network driver. As kubenet will be deprecated in the future, we need to make up for the missing part. This presentation will show our implementation that adds a simple CNI plugin using the linux tc to create an ingress(include burst) and egress(include burst) rate limiters. We have already contributed the CNI plugin to CNI community and the integration work with Kubernetes leading by Kubernetes SIG Network is in progress.
