Kubernetes Networking Solutions

The industry-leading SDN solution that facilitates application agility and data center automation. Cisco Application Centric Infrastructure integrates policy-based networking with Kubernetes through ACI CNI, enabling centralized network policy management across bare-metal and container workloads.

Converged Cloud Fabric is an automated fabric built with cloud networking design principles. Arista CCF provides intent-based networking for Kubernetes with EOS-based leaf-spine architecture, cloud-scale segmentation, and integration with Kubernetes network policy APIs.

Provides dynamic end-to-end networking policy and control for any cloud, any workload, and any deployment, from a single user interface. Contrail integrates with Kubernetes to deliver service chaining, micro-segmentation, and multi-cloud network automation.

Provides an agile software-defined infrastructure to build cloud-native application environments. NSX-T Data Center integrates with Kubernetes for container networking, micro-segmentation, load balancing, and distributed firewall policies across VMs and containers.

Networking plugin for pod networking in Kubernetes using Elastic Network Interfaces on AWS. VPC CNI assigns native AWS VPC IP addresses to pods, providing high throughput, low latency, and seamless integration with AWS security groups and VPC flow logs.

Use kubenet networking with your own IP address ranges in Azure Kubernetes Service (AKS). Kubenet is the basic network plugin for AKS that provides pod-to-pod connectivity using an overlay network with Azure routes, suitable for simpler cluster configurations.

IPvlan overlay-free Kubernetes networking in AWS by Lyft. This CNI plugin uses IPvlan for pod networking without overlay encapsulation, providing native AWS VPC performance with direct pod-to-VPC IP mapping and enhanced network visibility.

Provides and secures network connectivity and load-balancing between application workloads using eBPF technology. Cilium delivers L3/L4/L7 network policies, transparent encryption, observability, and deep integration with Hubble for network monitoring at kernel-level performance.

Open-source networking and security solution for Kubernetes supporting BGP routing, VXLAN/IP-in-IP overlays, and Kubernetes NetworkPolicy. Calico's Felix agent provides high-performance pod networking with fine-grained network policy enforcement at scale.

Kubernetes networking solution by VMware that operates at Layer 3/4 to provide networking and security services. Built on Open vSwitch, Antrea supports NetworkPolicy, ServiceLoadBalancer, and Pod-to-Pod connectivity with high-performance OpenFlow-based data plane.

A simple network fabric for containers designed for Kubernetes. Flannel uses VXLAN, host-gw, or IPsec backends to create a flat overlay network that gives each pod a unique IP across the cluster, making it one of the easiest CNI plugins to deploy and manage.

Container network interface plugin for Kubernetes that enables attaching multiple network interfaces to pods. Multus acts as a meta-plugin, delegating the primary interface to a base CNI while allowing additional interfaces for SR-IOV, DPDK, MACVLAN, and other specialized networking needs.

A turnkey solution for Kubernetes networking aiming to provide operational simplicity and high performance. Kube-router uses IPVS/LVS for service proxy, BGP for pod networking, and iptables for network policies, combining all three into a single daemonset.

Network and cluster containers across any environment — on-premises, cloud, or hybrid — with no code or complex configuration. Weave Net creates a virtual mesh network with automatic peer discovery, DNS-based service resolution, and optional encryption.

A network and security automation solution for cloud native applications. Romana provides layer 3 routing for pod networks without overlays, offering native IP addressing, micro-segmentation, and integration with Kubernetes NetworkPolicy for enterprise security requirements.

Daemons that translate virtual network configuration into OpenFlow and install them into Open vSwitch. OVN Kubernetes provides overlay networking, network policies, and DNS-based service discovery with OVN as the control plane for scalable, enterprise-grade K8s networking.

Integrates OVN-based network virtualization with Kubernetes, providing a feature-rich CNI plugin. Kube-OVN supports subnet management, floating IPs, VPCs, ACLs, NAT gateways, and pod-to-pod cross-node communication through OVN's distributed logical router.

Network controller plugin that brings OVN-based networking to NFV workloads on Kubernetes. OVN4NFV enables carrier-grade network functions with OVN's programmable pipeline, supporting service function chaining, bandwidth management, and multi-tenant isolation for telecom use cases.

Enables container orchestrators to seamlessly connect to the choice of CNI plugins installed on a host. CNI-Genie allows per-pod CNI selection, supporting Calico, Weave, Canal, Flannel, and host-local plugins simultaneously for multi-network environments.

A CNI-based network plugin for Kubernetes developed by Cybozu. Coil provides pod networking with Pool-based IPAM, supports NetworkPolicy, and offers seamless integration with both IPv4 and IPv6 dual-stack clusters for enterprise environments.

An easy-to-operate, high-performance, and secure Kubernetes networking plugin based on Open vSwitch. k-vswitch leverages OVS for advanced networking features including QoS, traffic mirroring, and packet capture for K8s cluster network management.

A CNI plugin to support multiple network interfaces in a Kubernetes pod by ZTE. Knitter enables advanced networking topologies where pods need access to multiple networks simultaneously, such as management, data, and storage networks in telco and NFV deployments.

Nokia's solution to bring telco-grade network management into a Kubernetes cluster. DANM provides multi-network support, IPAM integration, VLAN handling, and dynamic network configuration for 5G and telecom workloads requiring carrier-class reliability and performance.

An SDN solution for Kubernetes networking based on OpenDaylight. JAGUAR provides policy-driven network automation with OpenDaylight as the SDN controller, enabling advanced network topology management and service function chaining for research and enterprise environments.
