 ## Networking and Network Policy
 
 * [ACI](https://www.github.com/noironetworks/aci-containers) provides integrated container networking and network security with Cisco ACI.
-* [Antrea](https://antrea.io/) operates at Layer 3/4 to provide networking and security services for Kubernetes, leveraging Open vSwitch as the networking data plane.

 * [Calico](https://docs.projectcalico.org/latest/introduction/) is a networking and network policy provider. Calico supports a flexible set of networking options so you can choose the most efficient option for your situation, including non-overlay and overlay networks, with or without BGP. Calico uses the same engine to enforce network policy for hosts, pods, and (if using Istio & Envoy) applications at the service mesh layer.
 * [Canal](https://projectcalico.docs.tigera.io/getting-started/kubernetes/flannel/flannel) unites Flannel and Calico, providing networking and network policy.
-* [Cilium](https://github.com/cilium/cilium) is a networking, observability, and security solution with an eBPF-based data plane. Cilium provides a simple flat Layer 3 network with the ability to span multiple clusters in either a native routing or overlay/encapsulation mode, and can enforce network policies on L3-L7 using an identity-based security model that is decoupled from network addressing. Cilium can act as a replacement for kube-proxy; it also offers additional, opt-in observability and security features.

 ## 联网和网络策略
 
 * [ACI](https://www.github.com/noironetworks/aci-containers) 通过 Cisco ACI 提供集成的容器网络和安全网络。
 * [Antrea](https://antrea.io/) 在第 3/4 层执行操作，为 Kubernetes
   提供网络连接和安全服务。Antrea 利用 Open vSwitch 作为网络的数据面。
+  Antrea 是一个[沙箱级的 CNCF 项目](https://www.cncf.io/projects/antrea/)。
 * [Calico](https://docs.projectcalico.org/latest/introduction/) 是一个联网和网络策略供应商。
   Calico 支持一套灵活的网络选项，因此你可以根据自己的情况选择最有效的选项，包括非覆盖和覆盖网络，带或不带 BGP。
   Calico 使用相同的引擎为主机、Pod 和（如果使用 Istio 和 Envoy）应用程序在服务网格层执行网络策略。

 * [Contiv](https://contivpp.io/) provides configurable networking (native L3 using BGP, overlay using vxlan, classic L2, and Cisco-SDN/ACI) for various use cases and a rich policy framework. Contiv project is fully [open sourced](https://github.com/contiv). The [installer](https://github.com/contiv/install) provides both kubeadm and non-kubeadm based installation options.
 * [Contrail](https://www.juniper.net/us/en/products-services/sdn/contrail/contrail-networking/), based on [Tungsten Fabric](https://tungsten.io), is an open source, multi-cloud network virtualization and policy management platform. Contrail and Tungsten Fabric are integrated with orchestration systems such as Kubernetes, OpenShift, OpenStack and Mesos, and provide isolation modes for virtual machines, containers/pods and bare metal workloads.
