Since coding format of RF label is inconsistent with the protocol format of the information server's network, a design scheme of network architecture is proposed to achieve the connectivity between the decimal network based on IPV9 and the Internet network based on IPV4/IPV6. And also, two ways of information's Query and connectivity based on D-ONS and direct routing between the decimal network is devised by using the expert modules. The experiment results shows that both the two ways can provide efficient service of RFID Information Query .
