System and method for providing content-centric services using ultra-peer

摘要

To provide a content provision service to a user in conjunction with an end terminal and a P2P management server, a request for content is received based on a content name input from a user. It is checked whether the content corresponding to the content name is stored or not, and if the content is not stored, the content name is transmitted to the P2P management server to request content location information. Upon receiving the content location information from the P2P management server, a request for the content is sent to an adjacent content providing device listed in the content location information. Then, the content is received from the adjacent content providing device and provided to the user.

1. A peer device among a plurality of peer devices in a system for providing a content service to a user in conjunction with an end terminal and a peer-to-peer (P2P) management server, the peer device comprising:
a content storage which receives content from the end terminal and stores therein the content together with the content name, and, upon receipt of the content name, searches the content corresponding to the content name and provide the content; a content request collector which collects a content name in response to a content request from the end terminal, and, upon receiving a content location provision message from the P2P management server, reports the content name to the content storage; a content name creator which creates a name for the content delivered from the end terminal; a P2P management server registrar which reports the content name created by the content name creation unit to the P2P management server and registers the content name; and a content provider which receives user-requested content from the content storage and provides the user-requested content, wherein if the corresponding content is not present in the content storage, the content provider provides the user with content received from an adjacent service providing device, wherein the peer device interfaces with the end terminal and separately interfaces with the P2P management server, wherein the P2P management server comprises a content location provider which is configured to transmit to the peer device the content location provision message indicating in which one of the plurality of peer devices requested content is located, wherein the peer devices are user-manipulated portable electronic devices, wherein the content storage, the content request collector, the content name creator, and the P2P management server registrar are provided in the peer device, and wherein, upon receiving a content provision request from the adjacent service providing device, the content storage provides the content to the adjacent service providing device.
