WebOpenFlow actions ¶ Flows are defined by an OpenFlow controller by sending OFPT_FLOW_MOD messages to the datapath, by calling method send_flow_mod_add () or send_flow_mod_modify () on the controller stub. A flow definition includes the actions to perform on the packet in the flow. WebOVS uses OpenFlow for control of flows and OVSDB for configuration. OVS uses the sFlow protocol for packet sampling and monitoring. The code has been ported to work with multiple switching chipsets and has thus found a home in several hardware switches as well.
