Embodiment Construction

[0022] The present invention will be further described below through specific examples.

[0023] The current ONS uses a centralized root server (controlled by the United States) to resolve the entrance, and all EPC resolutions are resolved through the root server. This invention breaks this centralization based on EPC-encoded information, and passes through various countries. Control the EPC analysis of domestic items to realize decentralized management. In addition, the system supports both information service and discovery service by extending ONS signaling messages.

[0024] The decentralized management ONS architecture of the present invention is as image 3 shown. Among them, TLD1 authoritative server is equivalent to figure 2 The "root node" in , identifies the authoritative server of a certain country, such as the authoritative server of .cn or the authoritative server of .jp means the top authoritative server of the Chinese CN domain name and the top authoritative ...

Abstract

The invention relates to an object naming service (ONS) architecture with decentralized management-based electronic produce code (EPC) parsing method. The EPC parsing method comprises the following steps that: firstly, a URI Conversion unit reads a company prefix in an object code and determines a country code top level domain (ccTLD) area which the object code is located at; secondly, the URI Conversion unit carries out conversion on the object code, adds the ccTLD information, and constructs a complete domain name; thirdly, an ONS resolver unit receives the converted domain name and carries out parsing according to a normal DNS query flow until a name server of the domain name returns a corresponding naming authority pointer (NAPTR) record; and fourthly, a Local System unit accesses a corresponding an EPC information server (EPC IS) or EPC discovery server (EPC DS) according to the NAPTR record so as to obtain related information of the object. According to the invention, querying time delay and expenditure of the ONS can be optimized; and privacy protection of object information by all sovereign states and areas can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to an EPC analysis method based on a distributed management ONS architecture. Background technique [0002] As a centralized query service of the EPCglobal network, ONS (Object Naming Service) is used to resolve the EPC (Electronic Produce Code) of an item into the location of the corresponding manufacturer information. Its working principle is similar to traditional DNS service, but it adopts a single root service node, that is, the root node of EPC resolution service is only managed and maintained by VeriSign. This has seriously hindered the promotion and popularization of the EPCglobal network worldwide. For this reason, the industry has begun to explore how to extend the root node of ONS in a distributed way: one idea is to realize transparent peering between multiple nodes by using the overlay network architecture and service mode, such as the P2P-ba...
