Abstract:
Provided is a method for providing a user with information content which a neighboring user receives in a P2P network. The method for providing content information in a P2P network comprises the following steps. A user peer participates in a target P2P network, which provides target content, so as to download the target content. A P2P network management server provides the user peer with information on at least one neighboring P2P network in which at least one neighboring peer participates. The user peer requests an index server to send information on at least one neighboring content, which is provided by the at least one neighboring P2P network, by using the information on the at least one neighboring P2P network. The index server provides the user peer with the information on the at least one neighboring content.
Abstract:
PURPOSE: A data transmitting method of a wireless multi-cast agent on an overlay multicast network is provided to transmit un-received data to the wireless agent using a mobile multicast agent without changing the existing network structure. CONSTITUTION: A data transmitting method of a wireless multi-cast agent on an overlay multicast network comprises the following steps: determining the loss of data during a data receiving process using the wireless agent(S110); requesting lost data detected from the previous step to a mobile multicast agent(S120) using the wireless agent; determining whether the lost data is transmitted from the mobile multicast agent(S130); and completing the operation on the wireless agent when the response is received.

적어도 하나의 라우터를 포함하는 라우터 그룹 및 적어도 하나의 호스트 사이에 연결되는 본 발명의 실시 예에 따른 스위치의 동작 방법은 라우터 그룹으로부터 멀티캐스트 패킷을 전달받는 단계, 전달된 멀티캐스트 패킷을 라우터 그룹을 통해 다른 멀티캐스트 에이전트에 전달하여 중계 전송 멀티캐스팅을 수행하는 단계, 그리고 전달된 멀티캐스트 패킷을 적어도 하나의 호스트 중 멀티캐스트 패킷에 대응하는 멀티캐스트 그룹에 가입된 호스트에 전달하는 단계를 포함한다.
Abstract:
PURPOSE: A method for operating switch supporting relay multicasting is provided to increase the efficiency of multicast communication. CONSTITUTION: A multicast packet is received from a router group(100), and the received router packet is delivered to another multicast agent through the router group. Relay transmission multicasting is performed. The delivered multicast packet is delivered to a host subscribing for the multicast group among at least host, wherein the multicast group corresponds to the multicast packet.
