Overlay and P2P Networks
5
Networking and Services
Advanced studies
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: Overlay and p2p algorithms and systems, currently deployed systems, resource location, data delivery, reliability and performance issues, and legal and privacy issues.

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
