Thanks, Ben, All right. However, at least there is a mapping from the software implementation of a switch to its real component. Is that right? For example,The struct, dp_netdev, may be mapped to a switch, because of following mappings:1. member struct dp_netdev_queue queues[N_QUEUES] corresponds to actual buffer of a switch, every packet from input ports will enter this buffer first, then will be scheduled to go to its destined output port.2. member struct dp_netdev_port *ports[MAX_PORTS] corresponds to actual ports of a switch.Please correct me if I am wrong.
