%X Named data networking (NDN) routing strategy based on software defined network (SDN) centralized topology update separates the two key functions of routing. The topology update function is centralized in the SDN controller, while the route calculation function is distributed in the NDN content nodes. In addition, in this strategy, load-weighted preprocessing of the network topology can be performed under the premise of considering the state of the network. Simulation results show that in the NDN routing strategy based on the SDN centralized topology update, the delay of the first packet of the content request data stream is reduced by an average of 90%, the load of the SDN controller is reduced by an average of 10% to 30%, and the entire network realizes an effective load balancing.
