WebAn OpenFlow Controller is just a software package that interfaces with the switch via the OpenFlow API, and pushes routing rules. In a situation where you had a hardware-based openflow switch, the controller would reside on a separate host. WebOpenFlow flows are mapped to filter terms, and OpenFlow controller requests to add, delete, and modify flows result in the addition, deletion, or modification of terms in the filter. When the OpenFlow controller sends a flow modification request, the flow entry match condition for the ingress port determines which logical interface filter is ...

As shown in Fig. 5.1 the OpenFlow protocol defines the communication between an OpenFlow controller and an OpenFlow switch. This protocol is what most uniquely identifies OpenFlow technology. … WebOpenFlow explicitly specifies forwarding actions. Thus, a flow with an empty set of actions does not forward packets anywhere, causing them to be dropped. You can specify an empty set of actions with actions= on the ovs-ofctl command line. For example: $ ovs-ofctl add-flow br0 priority=65535,actions=. jessica holbrook clothing wool
