Described herein is a method for creating route summaries in an auxiliary network for a peer-to-peer (P2P) overlay network for routing a data packet. The method comprises dividing a d-dimensional Cartesian space of nodes in the P2P overlay network into multiple virtual grids that form the auxiliary network, numbering each virtual grid, summarizing default overlay network zones of the P2P overlay network corresponding to each of the virtual grids that form the auxiliary network, receiving a data packet, and routing the data packet to a packet destination using one of the P2P overlay network and the auxiliary network.
