Topological considerations are of paramount importance in the design of a P2P lookup service. We present TOPLUS, a lookup service for structured peer-to-peer networks that is based on the hierarchical grouping of peers according to network IP prefixes. TOPLUS is fully distributed and symmetric, in the sense that all nodes have the same role. Packets are routed to their destination along a path that mimics the router-level shortest-path, thereby providing a small "stretch". Experimental evaluation confirms that a lookup in TOPLUS takes time comparable to that of IP routing.
