Zusammenfassung: | The invention provides a processing method and device for window drift. The processing method comprises the steps that an ONU (Optical Network Unit) determines the successful repair of the window drift after correcting the window drift according to a drift value fed back by an OLT (Optical Line Terminal) and not receiving a message, which indicates the window drift, of the OLT any more within a preset time, the drift value of the current repair is stored, the ONU actively calls the drift value to adjust the internal delay of the ONU when the ONU restarts or performs ranging again, and uplink data is transmitted to the OLT after the adjustment. The adoption of the technical scheme solves a technical problem that the window drift still exists when the equipment performs ranging again after the window drift is processed in the related art, and realizes fast window drift repair of the ONU when the equipment restarts or performs ranging again.
本发明提供了种窗口漂移的处理方法及装置,其中,该方法包括:ONU在依据OLT反馈的漂移值修正窗口漂移之后,在预设时间内没有再接收到OLT指示窗 |
