+### CNI-Genie from Huawei
+
+[CNI-Genie](https://github.com/Huawei-PaaS/CNI-Genie) is a CNI plugin that enables Kubernetes to [simultanously have access to different implementations](https://github.com/Huawei-PaaS/CNI-Genie/blob/master/docs/multiple-cni-plugins/README.md#what-cni-genie-feature-1-multiple-cni-plugins-enables) of the [Kubernetes network model](https://github.com/kubernetes/kubernetes.github.io/blob/master/docs/concepts/cluster-administration/networking.md#kubernetes-model) in runtime. This includes any implementation that runs as a [CNI plugin](https://github.com/containernetworking/cni#3rd-party-plugins), such as [Flannel](https://github.com/coreos/flannel#flannel), [Calico](http://docs.projectcalico.org/), [Romana](http://romana.io), [Weave-net](https://www.weave.works/products/weave-net/).

+CNI-Genie also supports [assigning multiple IP addresses to a pod](https://github.com/Huawei-PaaS/CNI-Genie/blob/master/docs/multiple-ips/README.md#feature-2-extension-cni-genie-multiple-ip-addresses-per-pod), each from a different CNI plugin.
