Zusammenfassung: | To provide a signal transfer system capable of autonomously determining an optimum frame interval threshold value for each signal transfer device without any user operation.SOLUTION: When detecting that no high-priority traffic frame has come for more than a frame interval threshold value in a period allowing transmission of high-priority traffic frames, the period allowing transmission of high-priority traffic frames is released; a period allowing transmission of low-priority traffic frames is allocated; a frame interval of a plurality of frames that are input in time series is calculated based on a high-priority traffic frame arrival time; a new frame interval threshold value is calculated based on a plurality of frame intervals; and the current frame interval threshold value is changed to the new frame interval threshold value.SELECTED DRAWING: Figure 4
【課題】信号転送装置ごとに最適なフレーム間隔閾値をユーザ操作なく自律的に決定することができる提供する。【解決手段】優先度の高いトラヒックのフレームが伝送可能な期間に優先度の高いトラヒックのフレームがフレーム間隔閾値の時間以上来ないことを検出した場合は、優先度の高いトラヒックのフレームが伝送可能な期間を解放して、優先度の低いトラヒックのフレームが伝送可能な期間に割り当て、優先度の高いトラヒックのフレームの到着時刻に基づいて、時系列順に入力される複数のフレームのフレーム間隔を算出し、複数のフレーム間隔に基づいて、新たなフレーム間隔閾値を算出し、フレーム間隔閾値を新たなフレーム間隔閾値に変更する。【選択図】図4 |
