Abstract
A system and method of providing quality of service (QoS)-enabled digital content in peer-to-peer (P2P) networks are provided. The QoS-enabled service system on the P2P network includes: a service provider capable of providing digital content; one or more user nodes receiving digital content from the service provider; one or more donor nodes lending resources for providing digital content; and a supernode receiving information on user nodes and donor nodes, and a copy of digital content from the service provider, allowing the exchange of digital content among the user nodes through P2P networking, and when at least one user node experiences a P2P networking error during the exchange of the digital content, arranging for a predetermined number of donor nodes from among the one or more donor nodes to join the P2P networking. According to the system and method, even when the function of a peer does not normally work on a P2P network, a donor as a replacement of the peer is utilized, thereby providing QoS-enabled digital content to a user requesting the digital content.
