The popularity of peer-to-peer search networks continues to grow, even as the limitations to the scalability of existing systems become apparent. We propose a simple model for search networks, called the Search/Index Links (SIL) model. The SIL model describes existing networks while also yielding organizations not previouslystudied. Using analyticalandsimulation results, we argue that one new organization, parallel search clusters, is superior to existing supernode networks in many cases.
