摘要：E-Chord is a Distributed Hash Table algorithm (DHT) inspired from Chord, Pastry and CAN
algorithms. It meant to provide a keyword-based search in the Three-Layer Mediation Architecture. The
E-Chord is deployed in the middle layer (Integration Layer) of the architecture and provides services to
the higher layer (Presence Layer) and the lower layer (Homogenization Layer).
