description The invention discloses a virtual-real combined dynamic traffic scheduling method and device based on SDN and NDN, and the method comprises the steps: constructing an NDN network based on network topology, and enabling a virtual switch, a programmable switch, an SDN controller, a producer host, and a consumer host to be connected; when the producer host accesses or leaves the network, a request data packet is sent to the controller, and the controller updates producer data according to the request data packet; when a data packet is forwarded between the programmable switches or the virtual switches, the programmable switches or the virtual switches judge the type of the data packet; if the data packet is an IP data packet, carrying out two-layer and three-layer forwarding; if the data packet is an NDN interest packet, the data packet is forwarded according to the content storage table, the request interest table and the forwarding information table, when the forwarding information table is matched unsuccessfu
