Abstract: The latest EPC discovery service methods are summarized.On this basis,a link-style discovery service method based on Extended ONS is put forward.The storage problem of EPC item’s present position is resolved by extending ONS static information,and points databases are maintained in enterprise’s EPCIS,thus link-style discovery service is implemented.This method’s working process is introduced in detail,its key points such as reliability and security is carefully discussed,and corresponding resolving strategies are put forward.At last,this method is compared with others in many aspects,and its superiority is demonstrated.

摘要: 总结了目前最新的EPC网络发现服务方法,在此基础上,提出了一种基于扩展ONS的链式发现服务方法。该方法通过扩展ONS静态信息,解决了EPC物品的当前位置的存储问题,并通过在企业EPCIS中维护指针数据库,从而实现了链式发现服务。详细介绍了链式发现服务的工作过程,对其可靠性和安全性等关键点做了细致讨论,并提出了相应的应对策略。最后,从多个方面出发,将该方法与其他方法进行比较,论证了该方法的优越性。
