Abstract
In order to improve the scalability and reduce the traffic of Gnutella-like unstructured peer-to-peer networks, index caching mechanisms had been discussed in recent years. Some of them had modified the network architecture and adapted existing search methods for their mechanisms. Although the traffic of querying popular keywords could be reduced by using index caching mechanisms, the cached indices too redundant replications in the whole network.
We try to make the amount of indices fair for each file name in our index diffusing scheme. In our scheme, the indices with similar request rate would be grouped together, and the peers of the group who have indices with
higher request rate will receive query messages earlier. In the simulations, our architecture could perform queries with higher success rates than existing research in multilayer peer-to-peer networks, and the traffic is also decreasing conspicuously.
