Resource subscription method, resource subscription apparatus, and resource subscription system

摘要

A network resource subscription system is provided. In the present system, the subscription device and the publishing device respectively transmit the resource subscription request and the resource publishing request to the control device via the transfer device to establish a network resource tree. Next, the control device causes the subscription device to subscribe to the publishing device's resource information and causes the subscription device and the publishing device to perform P2P communication using a relatively complete matching method or an ambiguous matching method. This allows both transmission efficiency and subscription efficiency to be taken into account.
