1. A method of configuring a hierarchical network of user groups and resource groups, the method comprising the steps of:

  • (a) analyzing hierarchical connection relationships between the respective user groups and the respective resource groups, comparing redundancy rates of the respective hierarchical connection relationships, and determining a connection mode having a larger redundancy rate;

    (b) separating the respective user groups and resource groups and hierarchically connecting the user groups with the resource groups, according to the determined connection mode;

    (c) comparing hierarchical connections between the respective separated user groups and resource groups, and removing an overlapping hierarchical connection; and

    (d) recombining the hierarchical connections of step (c) except for the overlapping hierarchical connection, and configuring an entire network, wherein the redundancy rates are determined corresponding to a user group set (US) primary redundancy set (UPRS) and a resource group set (RS) primary redundancy set (RPRS),said analyzing, separating, comparing and recombining being performed by a server computer executing instructions stored in a memory to perform said steps.
