Through the analysis of the knowledge economy innovation structure, this paper puts forward own brand marketing strategys marketing model, namely combined with the clock information transmission and working mechanism optimization PTP clock node model to construct the rand marketing strategy model. In order to verify the practicability of the model, we have built network simulation structure and made simulation of synchronous networking accuracy test based on FTP data flow. The results show that the model has strong practicability and wide availability. Its idea applied in the research of brand marketing strategy in knowledge economy era has the advantages that are not available in other model.
