Organizational locality in prefix-based structured peer-to-peer overlays

摘要

Content and/or Path locality may be obtained using DHT protocols by assigning network nodes with individual node identifiers (IDs) in a hierarchical namespace. The hierarchical node IDs may be assigned to reflect organizational boundaries within the network. Therefore, with the structured overlay defined using these hierarchically assigned node IDs, a routing algorithm that uses prefix-matching can provide path locality. Furthermore, a domain prefix may be combined with data identifier derived from the data itself to create an enhanced data key. The use of the enhanced data key with a DHT protocol in this structured overlay can provide content locality.
