Abstract: The present invention discloses a passive optical network communications method: reporting, by an optical network unit, ONU, a calibration record of the ONU, where the calibration record includes an ID of a calibrated wavelength channel; sending a first message to the ONU when the OLT determines, according to the calibration record, that a target wavelength channel ID corresponding to a target wavelength channel to which the ONU needs to switch is not in the calibration record, where the first message includes a forced wavelength switching flag; and instructing the ONU to switch to the calibrated target wavelength channel. In this way, the ONU can implement wavelength switching quickly after calibrating a new wavelength channel so as to perform data communication over the calibrated new wavelength channel.

Abstract: This application discloses a remote desktop system, including a primary virtual machine, a plurality of secondary virtual machines, a primary terminal configured to log in to the primary virtual machine, and a secondary terminal configured to log in to a secondary virtual machine. When a user of the primary virtual machine needs to share image data of the primary virtual machine with a user of the secondary terminal for viewing, the primary virtual machine sends the image data to the primary terminal, and then the primary terminal shares the image data with the secondary terminal. This reduces data transmission pressure on a communications network between a virtual machine center and a terminal center.

Abstract: An upstream resource grant method, a device, a passive optical network, and a computer-readable storage medium are provided. The upstream resource grant method includes: obtaining, by an optical line terminal, an upstream grant message on which transformation processing has been performed, wherein a transformation parameter used for the transformation processing includes a physical identity of an optical network unit (ONU); and sending, by the optical line terminal, the upstream grant message on which the transformation processing has been performed, wherein the upstream grant message carries an upstream resource grant indication of the optical network unit, and the upstream resource grant indication indicates an upstream resource granted to the optical network unit. According to this application, an occurrence probability of a rogue ONU phenomenon is reduced, thereby improving service running stability of a PON system.
