Hi, You may want to have a look at 'OVS/lib/dpif-netdev.c' file. You can start with the 'dp_netdev_process_rxq_port()' function and follow the calls. You can see for ex. dp_netdev_input() which at first calls emc_processing() and in case a match is not found in the EMC it will call fast_path_processing() to check for a match inside the Classifier. In case it is still unsuccessful it will make an 'up-call' to the 'ofproto' table via dp_netdev_upcall() so that it knows what to do with that packet. As a consequence new Rules and Flows, see dpcls_insert(), and dp_netdev_flow_add() are inserted into the tables, so that next time they will 'know' what to do with similar packets.
