Analyzing the algorithm of DHT and studying the thinking of the B + tree, we got a new network models -Frustum of a cone network. This network models will bring us to three-dimensional network from two-dimensional network, from plane to solid. Setting the end points, the routing table to be dynamic growth two-dimensional tables, we realized three-dimensional end point search and improved query efficiency. The updates of Limited length of follow-up list and limited delivery times, ensure that the entire network will be stable, also ensure that the system be much less than the chord algorithm in costs of the maintenance.
