Pure peer-to-peer systems are loosely coupled, highly autonomous systems with a simple architecture, typically without hierarchy. Often, flooding-based routing me chanisms are used for sending messages through the overlay (application level) network. Due to the limited scalability and high network load experiences, the paper suggests an improvement to reduce the traffic and overall performance: if a peer remembers recently forwarded answers, it may route the next query messages asking about the same contents only to the relevant neighbour, not to all of them. The routing simulations have shown promising results.
