16. What is Peer-to-peer?
Hub-and-Spoke network
Hub-and-spoke:
- centralized
- Single point of failure
- cost of a server
- adding more clients make network slower
Centralized server-based service model.
- need failover and backups
P2P network
P2P
- decentralized
- adding more clients make network faster
- robustness, no failover
A peer-to-peer system of nodes without central infrastructure.

17. What is Peer-to-peer?
 Point-to-point one-to-one  “Swarming” many-to-many
 Live streaming  Large- le download (possibly progressive)
 Document delivery
*Connections in step 2
 Live Application-Level Multicast one-to-many  Distributed Data Storage (distributed hash table)
 Broadcast (1 to many, some latency tolerable)  DHT-like structures to form distributed database
 Interactive (many to many, or 1 to many with feedback,
low latency required)
