Distributed Planetary Object Name Service: Issues and Design Principles
Résumé
The ONS is a central lookup service used in the EPCglobal network for retrieving the location of information about a specific EPC. This centralized solution lacks scalability and fault tolerance. We present the design principles of a distributed solution for ONS lookup service. In distributed systems, the problem of providing a scalable location service requires a dynamic mechanism to associate identification and location. We show that the use of Distributed Hash Tables (DHT) is a good candidate for distributing as it provides such a mechanism. We then outline how to adapt the DHT principles (operations on objects or nodes) to the ONS distribution problem.
