 * [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. Antrea is a [CNCF project at the Sandbox level](https://www.cncf.io/projects/antrea/). 
-* [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. Cilium is a [CNCF project at the Incubation level](https://www.cncf.io/projects/cilium/).
 * [CNI-Genie](https://github.com/cni-genie/CNI-Genie) enables Kubernetes to seamlessly connect to a choice of CNI plugins, such as Calico, Canal, Flannel, or Weave. CNI-Genie is a [CNCF project at the Sandbox level](https://www.cncf.io/projects/cni-genie/).
