Question

Which P2P system uses a 1 hop Lookup DHT (Distributed Hash Table) ?

Answer 1

Answer:

Napster, the first large-scale P2P content delivery system, required a central index server: each node, upon joining, would send a list of locally held files to the server, which would perform searches and refer the queries to the nodes that held the results.

Answer 2

The system that used a 1 hop Lookup DHT was Napster.

• Initially, DHT work was inspired in part by various peer-to-peer networks.
• One of the network was Napster, which used resources distributed over the Internet to provide a single usable application.
• Napster was the first P2P content delivery system at a large scale.
• It needed a central index server, where each node used to give the server a list of local files, that would scan and refer the queries to the nodes holding the data.
