Abstract:
Provided is a method of remotely controlling local network devices. The method includes periodically receiving an access request from each local network device in a local network, to which direct access from the outside is blocked, if a connection between a local network device and a server located outside the local network is formed as a result of receiving the access request, determining whether a command to be transmitted to the local network device exists, and if it is determined that a command to be transmitted to the local network device exists, transmitting the command to the local network device while the connect is being formed to control the local network device.
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.
