Abstract

Techniques are described for sharing content among peers. Locality domains are treated as first order network units. Content is located at the level of a locality domain using a hierarchical DHT in which nodes correspond to locality domains. A peer searches for a given piece of content in a proximity guided manner and terminates at the earliest locality domain (in the hierarchy) which has the content. Locality domains are organized into hierarchical clusters based on their proximity.
