"The Query Routing Protocol (QRP for short) is an essential part of the Ultrapeer specification: it governs how the Ultrapeer will filter queries and only forward those to the leaf nodes most likely to have a match. This is done without even knowing the resource names, by looking the query words through a big hash table, that is sent by the leaf node to its Ultrapeer.
The aim of the QRP is to avoid forwarding a query that cannot match, it is not to forward only those queries that will match." QRP |
