摘要：A software-defined network-based method and system for implementing acontent distribution network. An application function, control function, and network

entity resource of a CDN are added respectively to an application layer, control layer,and data forwarding layer of an SDN. When a request for a CDN application is received,the SDN application layer generates resource requirement and service schedulinginformation based on the request, and transmits a reservation request for a resourcerequired by the CDN application to an SDN control layer. The SDN control layer allocatesa resource required by the CDN application to combine network load balancing and pathpolicies and to generate a content routing table for data transmission, generating andtransmitting L2 and L3 forwarding tables to the SDN data forwarding layer. When itreceives content distribution and content delivery requests, the SDN data forwardinglayer executes a CDN service-related operation based on the forwarding tables.
