Structured P2P

For Distributed HashTable services, refer to [Design] Distributed hash table.

Conclusion

1. Unstructured P2P:

   1. no coupling between nodes and file location
   2. Centralized direcotry service (except Gnutella)
   3. Search by flooding (overhead)
   4. Hierarchical architecture (non-scalable)

2. Structured P2P:

   1. tight coupling between nodes and file location
   2. DHT using consistent hashing (eg. Chord, and many other types)
   3. A node is assigned to hold particular content
   4. Search with more efficiency
