- 1CORDP2P lookup protocol for internet apps
- 2P2P NetworksEvery node performs the same function and no point of failure
- 3Napster- Semi centralised P2P network
- Centralised index and network management
- File transfer are P2P - 4BitTorrent- Distributes data & electronic files over internet
- Client is a program that implements BitTorrent protocol
- Allows client to find peer users known as seed who may transfer files - 5Trade-offs- Nodes in P2P tend to be unreliable
- Increased rate of failure
- Weak security
- High latency
- No centralised control - 6Scalability- Bottlenecks in nodes can limit capacity or reliability
- Query flooding returns poor results if nodes fail
- Bandwidth limitations increase latency - 7Lookup protocols- Insert (key, value)
- Lookup(key) = value - 8Chord protocol- Set of algorithms for implementing lookup operations of Distributed Hash Table
- Hops are logarithmic
