Traditional Distributed Hash Tables (DHT) abstraction distributes data items among peer nodes on a structured overlay network in storage-intensive applications. The question is whether DHT-based systems can provide reliable and scalable storage services also in stock-oriented applications, where logistics, traceability and fault-tolerance are the main requirements. In this paper a novel approach to self-organizing stock management networks, based on a two-level DHT mechanism is proposed and analyzed. Some preliminary results suggest that our method can reduce network traffic and achieve high data availability also in such storage and management networks.
