Embedding locations in DHT node IDs makes locality explicit and, thereby, enables engineering of the trade-off between careful placement and randomized load balancing. This paper discusses hierarchical, topology-exposed DHTs and their benefits for content locality, and administrative control and routing locality.

KEYWORDS: distributed hash table, peer-to-peer, routing locality, content locality, load balance
