VIRTUAL AND REAL COMBINED DYNAMIC TRAFFIC SCHEDULING METHOD AND APPARATUS BASED ON SDN AND NDN

Disclosed in the present invention are a virtual and real combined dynamic traffic scheduling method and apparatus based on SDN and NDN. The method comprises: constructing an NDN on the basis of network topology, and connecting virtual switches, programmable switches, an SDN controller, producer hosts and consumer hosts; when the producer hosts access or leave the network, sending a request data packet to the controller, and the controller updating producer data according to the request data packet; when the data packet is forwarded between the programmable switches or the virtual switches, the programmable switches or the virtual switches judging the type of the data packet; if the data packet is an IP data packet, carrying out L2/L3 forwarding; if the data packet is an NDN interest packet, forwarding same according to a content storage table, a pending interest table and a forwarding information base, and when the forwarding information base fails to match, the switches sending a request to the controller,
