Abstract:
1. A quality-of-service (QoS)-enabled service system on a peer-to-peer (P2P) network, the system comprising: a service provider which provides digital content; a plurality of user nodes which receive the digital content from the service provider; one or more donor nodes which lend resources for providing the digital content; and a supernode which receives information on the user nodes and the donor nodes, and a copy of digital content from the service provider, allows exchange of digital content among the user nodes by P2P networking, and if at least one user node experiences a P2P networking error during the exchange of the digital content, wherein the supernode is capable of selectively providing a method of providing QoS-enabled digital content and a method of providing QoS-non-enabled digital content to the user of the user node, wherein the supernode provides QoS-enabled digital content by arranging for at least one donor node from among the one or more donor nodes to join the P2P networking, and wherein the supernode provides QoS-non-enabled content by waiting until the user node which experienced the networking error returns to the network or a new user having the digital content is connected to the network.
