| // This extension enables the switch to send only one packet-in for a given flow. |
| // The goal is to reduce the load on the controller, particularly in the case of |
| // large UDP streams. |
| // |
| // When this extension is enabled (by sending the BSN_SET_DEDUPLICATION message |
| // described below with enabled=1) the switch will install an exact-match drop |
| // flow for each packet-in. This flow has the idle_timeout, hard_timeout, |
| // priority, and cookie fields set to the values given in the |
| // BSN_SET_DEDUPLICATION message. |
| // |
| // This extension does not affect packet-ins caused by an output to |
| // OFPP_CONTROLLER. |
| // |
| // When this extension is enabled the switch may still send multiple packet-ins |
| // for the same flow. |
| // |
| // This extension keeps its configuration across controller disconnects. When a |
| // controller that is aware of this extension connects to a switch it should send |
| // a DELETE flow-mod with the cookie field set to ensure that it receives |
| // packet-ins for ongoing flows. |
| // |
| // The flows installed by this extension are not automatically deleted when the |
| // extension is disabled. Similarly other configuration changes (cookie, etc) do |
| // not affect already-installed flows. |
