Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flowchart of an energy saving method for an optical network unit according to an embodiment of the present invention.
The energy saving method for the onu according to the embodiment of the present invention may be applied to a System-on-a-Chip (SOC) of the onu, and includes steps S11 to S14, which are specifically as follows:
s11, in the process of data uplink transmission of the optical network unit, when entering a sending interval between two data packets, acquiring parameter information of the sending interval; wherein the parameter information of the sending interval comprises a starting time, an ending time and a duration of the sending interval;
s12, when the duration time of the sending interval is judged to be larger than a preset time threshold, setting a sleep time period according to the parameter information of the sending interval and preset conditions; wherein neither a start time nor an end time of the sleep period is earlier than a start time of the transmission interval nor later than an end time of the transmission interval;
s13, controlling the optical module of the optical network unit to stop emitting light in the sleep time period;
and S14, controlling the light module to return to normal light emission when the sleep time period is over.
The transmission interval between two data packets refers to an interval between the transmission end time of the previous data packet and the transmission start time of the next data packet.
It should be noted that, in a specific implementation, the preset time threshold may be set according to an actual situation, and is not limited herein.
It should be noted that, in specific implementation, the preset condition may be set according to actual needs, for example, the start time of the sleep period is set as the start time of the transmission interval, and the end time of the sleep period is set as the end time of the transmission interval, or other conditions are met, and it is sufficient that neither the start time nor the end time of the sleep period is earlier than the start time of the transmission interval, but not later than the end time of the transmission interval, which is not limited herein.
It can be understood that the uplink data packets of the ONU need to be transmitted strictly according to the allocated time, the uplink data packets are uniformly scheduled by the inside of the ONU to transmit uplink frames, the time stamps of the data packets are marked by the data frames of the ONU, and the transmission interval between the two data packets is completely controlled by the ONU.
In the process of data uplink transmission of the existing optical network unit, if a small transmission interval 1 exists between a data packet 1 and a data packet 2, and a large transmission interval 2 exists between a data packet 2 and a data packet 3, in the transmission intervals 1 and 2, the optical network unit is always in a light-emitting state regardless of whether the duration of the transmission intervals 1 and 2 is long, and the optical network unit does not transmit the data packet in the transmission intervals 1 and 2, so that energy waste is caused. In order to solve the problem, an embodiment of the present invention provides an energy saving method for an optical network unit, where in a data uplink transmission process of the optical network unit, when a transmission interval between two data packets enters, that is, when a current data packet is finished being transmitted, parameter information of the transmission interval is obtained, and then a size relationship between a duration of the transmission interval and a preset time threshold is determined. Because the light-emitting of the optical module is turned off and on in a smaller sending interval, the packet loss phenomenon is easy to occur, when the duration time of the sending interval is judged to be less than or equal to the preset time threshold, the normal light-emitting of the optical network unit is kept, so that the packet loss phenomenon is avoided, and the communication quality is ensured; and when the duration of the sending interval is judged to be greater than the preset time threshold, setting a sleep period according to the parameter information of the sending interval, and controlling the optical module of the optical network unit to stop emitting light in the sleep period, namely, to stop driving the laser of the optical module to emit light, so that the energy waste is avoided, the power consumption of the optical network unit is reduced, and finally, when the sleep period is ended, controlling the optical module to recover to emit light normally, namely, controlling the laser of the optical module to emit light normally, so that the optical network unit recovers to work normally, and the next data packet can be transmitted continuously.
Preferably, referring to fig. 2, after step S12, the method further includes the steps of:
and S15, stopping sending idle codes to the optical line terminal in the dormant period.
In the data uplink transmission process of the existing optical network unit, the optical network unit sends an idle code, that is, an IDEL packet, to the optical line terminal in each sending interval, which also further causes energy waste. In order to solve the problem, the preferred embodiment provides an energy saving method for an optical network unit, which stops sending an idle code to an optical line terminal in a sleep period, thereby further reducing the power consumption of the optical network unit.
As a preferred scheme, the controlling the optical module of the optical network unit to stop emitting light specifically includes:
and stopping sending the burst enabling signal to the optical module of the optical network unit, so that the optical module stops emitting light.
Wherein the sending of the burst enable signal to the laser driver in the optical module of the optical network unit is stopped, thereby stopping the laser of the optical module from emitting light.
As a preferred scheme, the setting a sleep period according to the parameter information of the transmission interval and a preset condition specifically includes:
acquiring the time required by starting a laser of the optical module;
setting the dormancy period by taking the X time as the starting time of the dormancy period and the Y time as the ending time of the dormancy period; the X time and the Y time are neither earlier than the starting time of the sending interval nor later than the ending time of the sending interval, and the time difference between the Y time and the ending time of the sending interval is larger than or equal to the time required by starting the laser of the optical module.
Because the laser of the optical module needs a certain time to be turned on, if the laser is not turned on when the data packet needs to be sent, the data packet cannot be sent normally, and the communication quality is affected. Therefore, in the preferred embodiment, the time difference between the end time of the sleep period and the end time of the transmission interval is set to be greater than or equal to the time required for turning on the laser of the optical module, so that the laser can be enabled to normally turn on to emit light at the end of the transmission interval, and thus, a data packet after the end of the transmission interval can be normally transmitted, and the communication quality is ensured.
Preferably, the preset time threshold is a sum of time required for turning on the laser of the optical module, time required for turning off the laser of the optical module, and preset protection time.
In specific implementation, the preset protection time may be set according to an actual situation, and is not limited herein.
When the optical network unit works in a GPON system, the time required for opening and closing a laser of an optical module is 12.8 ns; when the optical network unit works in an EPON system, the time required for turning on and the time required for turning off the laser of the optical module are both 512 ns.
Because the laser of the optical module needs a certain time to be turned on and off, if the duration of the sending interval is less than the sum of the time required for turning on the laser of the optical module and the time required for turning off the laser of the optical module, the laser of the optical module does not have enough time to complete normal turning on and off, and data transmission errors are caused, thereby affecting the communication quality. Therefore, in the preferred embodiment, the preset time threshold is set as the sum of the time required for turning on the laser of the optical module, the time required for turning off the laser of the optical module, and the preset protection time, so that the laser of the optical module can have enough time to complete normal turning on and off in the sending interval, and the communication quality is ensured.
Optionally, when the optical network unit works in a GPON system, the preset protection time is 10 ns.
Optionally, when the optical network unit operates in an EPON system, the preset protection time is 100 ns.
It should be noted that the above-mentioned preferred embodiments may be arbitrarily combined to obtain a more preferred embodiment of the present invention.

In the process of data uplink transmission of the optical network unit, when the duration of the transmission interval between two data packets is judged to be greater than the preset time threshold, the sleep time period is set according to the parameter information and the preset condition of the transmission interval, the optical module of the optical network unit is controlled to stop emitting light, and the optical module is controlled to recover normal light emission after the sleep time period is ended, so that the optical network unit can keep normal light emission in the transmission interval with the duration less than or equal to the preset time threshold, the occurrence of a packet loss phenomenon is avoided, the communication quality is ensured, and the light emission can be stopped in the transmission interval with the duration greater than the preset time threshold, so that the power consumption of the optical network unit can be effectively reduced, the energy conservation with higher efficiency is realized, and the temperature of the optical network unit can be effectively reduced.
