WebOpenFlow is a programmable network protocol that manages and directs traffic among Ethernet switches, routers, and wireless access points over the network in support of Software-Defined Networking (SDN) applications. OpenFlow enables network controllers to determine the path of network packets across a network of switches. The controllers are distinct from the switches. This separation of the control from the forwarding allows for more sophisticated traffic management than is feasible using access control lists (ACLs) and routing protocols. Also, OpenFlow allows switches from different vendors — often each with their own proprietary interfaces and scripting languages — to be managed remotely u…

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=.
