General
Overlay networks and peer-to-peer technologies have become key components for building large scale distributed systems. This course will introduce overlay networks and peer-to-peer systems, discuss their general properties, and applications. The course will cover the following topics:
- Currently deployed peer-to-peer systems and how they work
- Distributed Hash Tables as a base for structured peer-to-peer systems
- Peer-to-peer storage systems and their performance evaluation
- Performance issues, legal aspects, and privacy issues
- Peer-to-peer content distribution algorithms
