IPC: H04L12/00
Filed: 2001-05-10
Abstract: PURPOSE: A data transmitting and receiving method and system using a satellite router are provided to offer a convenient use of a satellite service and obtain an economical efficiency at the side of nation by adding a satellite router to an existing network system to enable a satellite communication service by using a conversion function of a multicast address and a unicast address. CONSTITUTION: A satellite router service server periodically generates a pilot signal and transmits the generated pilot signal to a satellite router through a satellite(S2). The satellite router checks a data transmission state of a satellite line by using the pilot signal(S4). The satellite router transmits a corresponding pilot response signal to an agent of an information providing system(S6). The agent analyzes the data transmission state of the satellite line according to the pilot response signal and continuously maintains the data transmission through the satellite line if the data transmission state is good(S10). If the data transmission state of the satellite line is not good, the agent requests a change of the data transmission path from a transmission router so that a data can be transmitted through a preliminary network(S12). The transmission router changes a transmission path so that the data that has been transmitted through the satellite line can be transmitted to the preliminary network(S14). At this time, since the satellite router service server periodically generates a pilot signal, if the transmission state of the satellite line becomes good, the data transmission path can be changed to transmit the data through the satellite line.
