Design and implementation of efficient distributed Name Service in EPC Network

EPC (Electronic Product Code) Network provides public services for companies to share product data throughout the supply chain, and enables trading partners to track and trace the items. In EPC Network, Name Service serves as a centralized tracker to locate the EPCIS (EPC Information Service) repositories that store the distributed data of the EPC-tagged products at item-level. It is an essential component that enables interoperability across companies. In this paper, we propose an efficient and flexible distributed Name Service architecture for large scale application in the EPC network. Our architecture includes a novel ONS (Object Name Service) design that supports customized EPC encoding and a scalable distributed DS (Discovery Service) architecture that enables efficient register/query for massive item-level records.
