In their own words
Antrea
Antrea provides networking and security for Kubernetes workloads by implementing the Container Network Interface and Kubernetes NetworkPolicy. It uses Open vSwitch as its data plane, including for Kubernetes Service load balancing. Depending on infrastructure and use case, clusters can use VXLAN or Geneve overlays or run without an overlay. Antrea extends Kubernetes policy controls with tiers, rule priorities, cluster-level policies, and Node policies. It can federate clusters with a unified data plane, multi-cluster Services, and security posture. Diagnostics include command-line and UI tools for packet tracing, policy analysis, and flow inspection; metrics can be exported to Prometheus. Pod traffic encryption with IPsec or WireGuard is supported between Linux nodes, but not on Windows nodes. Deployment guides cover Amazon EKS, Azure AKS, and Google GKE, with GKE marked Alpha. The project requires a Kubernetes cluster and the Open vSwitch kernel module on every node, and its overview says it has been tested with Kubernetes 1.23 or later. Antrea is an open-source CNCF sandbox project under Apache License 2.0.
Network Service Mesh
Network Service Mesh connects workloads across clusters and clouds through a hybrid, multi-cloud IP service mesh. Each workload can connect independently to zero or more Network Services, regardless of where it runs. The project says it works with an existing CNI without requiring changes to Kubernetes or workloads. Services can provide connectivity, security, and observability at Layer 3 and above, carrying IP or Ethernet payloads.
Clients may be Kubernetes pods, virtual machines, or physical servers. They authenticate independently, currently using SPIFFE IDs, and need authorization to attach. Clients request and close virtual wires over gRPC and can monitor connection status through a streaming call. Endpoint selection offers composition, selective composition, topology awareness, and scale from zero. A service may also provide domain-scoped DNS for connected pods. The architecture describes integration with Istio, Linkerd, Consul, and Kuma. Network Service Mesh is a CNCF sandbox project and is free and open source. Its run guide lists Docker, Go, a Kubernetes cluster, and kubectl as prerequisites; most examples require at least two worker nodes.
