Chapter 1. About networking
Chapter 1. About networking Red Hat OpenShift Networking is an ecosystem of features, plugins and advanced networking capabilities that extend Kubernetes networking with the advanced networking-related features that your cluster needs to manage its network traffic for one or multiple hybrid clusters. This ecosystem of networking capabilities integrates ingress, egress, load balancing, high-performance throughput, security, inter- and intra-cluster traffic management and provides role-based observability tooling to reduce its natural complexities. The following list highlights some of the most commonly used Red Hat OpenShift Networking features available on your cluster: Primary cluster network provided by either of the following Container Network Interface (CNI) plugins: OVN-Kubernetes network plugin , the default plugin OpenShift SDN network plugin Certified 3rd-party alternative primary network plugins Cluster Network Operator for network plugin management Ingress Operator for TLS encrypted web traffic DNS Operator for name assignment MetalLB Operator for traffic load balancing on bare metal clusters IP failover support for high-availability Additional hardware network support through multiple CNI plugins, including for macvlan, ipvlan, and SR-IOV hardware networks IPv4, IPv6, and dual stack addressing Hybrid Linux-Windows host clusters for Windows-based workloads Red Hat OpenShift Service Mesh for discovery, load balancing, service-to-service authentication, failure recovery, metrics, and monitoring of services Single-node OpenShift Network Observability Operator for network debugging and insights Submariner for inter-cluster networking Red Hat Service Interconnect for layer 7 inter-cluster networking
