OpenSDN

OpenSDN, formerly Tungsten Fabric (TF), provides basic L2/L3 networking to an OpenStack environment running on the MKE cluster and includes the IP address management, security groups, floating IP addresses, and routing policies functionality.

OpenSDN is based on overlay networking, where all virtual machines are connected to a virtual network with encapsulation (MPLSoGRE, MPLSoUDP, VXLAN). This enables you to separate the underlay Kubernetes management network. A workload requires an external gateway, such as a hardware EdgeRouter or a simple gateway to route the outgoing traffic.

The OpenSDN vRouter uses different gateways for the control and data planes.
