<p>PROBLEM TO BE SOLVED: To enable a server to extract effective data from data received from a client surely and in real time. SOLUTION: While respective clients A, B, C mutually ensure the time synchronization of respective internal clocks, each client adds a time stamp to transmission data. The server begins (S1, S2) time-out monitor on receiving the first received data, if the data received later on are within the time-out, and the reception order of the data is in a correct succession, the data are assumed to be effective for the combination of the data and another data received (S3 to S5). Ineffective data are discarded (S6), and the effective data are added to another data received (S7). These steps are repeated until the whole data are received, or if it is the time-out, standby is terminated (S8, S9). In addition, depending on the delay status of data received from the client, the time-out is extended by a timeαthat has been set as variable.</p> |
