Abstract: For the primary and secondary education resource sharing issues, an education resource sharing network architecture was designed and the functions of nodes in each layer were defined in this paper. To reduce the network delay and improve the network utilization, we explored the methods and measures from the two angles of the network topology and communication efficiency. Firstly, we constructed a logic RP(k) network among the management nodes, and then, to improve the QoS of education resource sharing system, a series of key strategies based on the RP (k) were proposed.These strategics included the node joins or leaves strategy, distributed resource retrieval strategy and the data coopera-tive strategy. Finally, the advantages of the logic RP(k) network and the effectiveness of correlated strategics were confirmed by theoretical analysis and comparison.
