Overlay and P2P Systems: Protocols and Applications - 11/09/2002

Soma Ghosh

Overlay systems can be used to deploy a wide-range of sophisticated applications such as scalable media streaming and scalable information retreival and lookup services without requiring modification to the underlying network infrastructure. This new generation of scable P2P systems is based on some underlying P2P protocols and overlay topology construction algorithms. One such is Distributed Hash Tables(DHT). The DHT functionality is proving to be a useful substrate for large distributed overlay systems and an integral part of the P2P landscape. I will be going over some of these DHT operations as discussed in the NGC tutorial.
