C++ (Cpp) foreach_port Examples

Example #1

File: switch.c Project: iqm/apps

static void
send_packet_out_for_each_switch( switch_info *sw, const buffer *packet, uint64_t dpid, uint16_t in_port ) {
  openflow_actions *actions = create_actions();
  int number_of_actions = foreach_port( sw->ports, build_packet_out_actions, actions, dpid, in_port );

  if ( number_of_actions > 0 ) {
    send_packet_out( sw->dpid, actions, packet );
  }
  delete_actions( actions );
}

Example #2

File: sliceable_switch.c Project: daisuke-k/trema-apps

static void
send_packet_out_for_each_switch( switch_info *sw, void *user_data ) {
  openflow_actions *actions = create_actions();
  port_params params;
  params.switch_params = user_data;
  params.actions = actions;
  foreach_port( sw->ports, build_packet_out_actions, &params );

  // check if no action is build
  if ( actions->n_actions > 0 ) {
    const buffer *packet = params.switch_params->packet;
    send_packet_out( sw->dpid, actions, packet );
  }

  delete_actions( actions );
}
