This paper proposed a new software-based Content Distribution Network (CDN) model. First, we overviewed some related technologies of CDN. Then, software CDN model was built, and the key strategies of load balancing, content distribution and file transfer were explored in the software CDN model. Also in this model, the load balancing algorithm based on load equilibrium with latency and the content distribution algorithm of the non-hot media based on Markov prediction were discussed in detail. Finally, an on-demand video system was designed to verify the feasibility of the proposed model.
