Description

Technical Field

[0001] This application relates to the field of optical communication technology, and in particular to a method, apparatus, device, storage medium, and program product for setting a silent window. Background Technology

[0002] A Passive Optical Network (PON) may include an Optical Line Terminal (OLT) installed at a central control station, and a number of Optical Network Units (ONUs) installed at user sites. The Optical Distribution Network (ODN) between the OLT and ONUs includes optical fibers and passive splitters or couplers.

[0003] In related technologies, the registration and activation of ONUs are completed through a state machine cycle defined in the standard protocol. During this cycle, the OLT needs to periodically provide a silent window for the ONUs at fixed intervals, allowing offline ONUs and ONUs with specified ranging to report relevant signaling messages to the OLT within the corresponding time period of the silent window.

[0004] However, a normally functioning ONU cannot transmit data within the time period corresponding to the silent window, which increases the data transmission latency of a normally functioning ONU. Summary of the Invention

[0005] This application provides a method, apparatus, device, storage medium, and program product for setting a silent window, which can reduce the data transmission latency of a normally functioning ONU and improve the uplink transmission quality of the ONU.

[0006] Firstly, this application provides a method for setting a silent window, the method including:

[0007] When the passive optical fiber network (PON) channel of the optical line terminal (OLT) meets the window closing conditions, stop opening a silent window for the PON channel.

[0008] The silent window is used to activate the optical network unit (ONU) upon its online launch.

[0009] In one embodiment, the method includes:

[0010] Based on the status of each ONU corresponding to the PON channel, determine whether the PON channel meets the window closing condition.

[0011] In one embodiment, determining whether the PON channel meets the window closing condition based on the status of each ONU corresponding to the PON channel includes:

[0012] If all ONUs corresponding to the PON channel are online, then the PON channel meets the window closing condition.

[0013] In one embodiment, determining whether the PON channel meets the window closing condition based on the status of each ONU corresponding to the PON channel further includes:

[0014] If some ONUs corresponding to the PON channel are offline, and the number of times the silent window is provided to the PON channel exceeds a preset threshold, then the PON channel is determined to meet the window closing condition.

[0015] In one embodiment, the method further includes:

[0016] If some ONUs corresponding to the PON channel are offline, and the number of times the silent window is provided to the PON channel does not exceed the preset threshold, then after a first preset time interval, the PON channel is re-determined to determine whether the window closing condition is met based on the status of each ONU corresponding to the PON channel.

[0017] In one embodiment, the method further includes:

[0018] After the second preset duration of stopping the opening of the silent window for the PON channel, determine whether the PON channel meets the opening window conditions;

[0019] If the PON channel meets the windowing conditions, a silent window is opened for the PON channel.

[0020] In one embodiment, determining whether the PON channel meets the windowing conditions includes:

[0021] Based on the status of each ONU corresponding to the PON channel, determine whether the PON channel meets the windowing conditions.

[0022] In one embodiment, determining whether the PON channel meets the windowing conditions based on the status of each ONU corresponding to the PON channel includes:

[0023] If some ONUs corresponding to the PON channel are offline, then the PON channel is determined to meet the windowing condition.

[0024] In one embodiment, the method further includes:

[0025] If all ONUs corresponding to the PON channel are online, then after a third preset time interval, the PON channel is re-determined to determine whether it meets the windowing conditions based on the status of each ONU.

[0026] Secondly, this application also provides a device for setting a silent window, the device comprising:

[0027] The configuration module is used to stop opening a silent window for the PON channel when the passive fiber network PON channel of the optical line terminal (OLT) meets the window closing conditions.

[0028] The silent window is used to activate the optical network unit (ONU) upon its online launch.

[0029] Thirdly, this application also provides an optical line terminal, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps of the method described in the first aspect.

[0030] Fourthly, this application also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the method described in the first aspect.

[0031] Fifthly, this application also provides a computer program product comprising a computer program that, when executed by a processor, implements the steps of the method described in the first aspect.

[0032] The aforementioned method, apparatus, device, storage medium, and program product for setting a silent window stop opening a silent window for a PON channel when the passive optical network (PON) channel in the optical line terminal (OLT) meets the window closing conditions; wherein, the silent window is used to activate the optical network unit (ONU) upon online operation. It is evident that, compared to related technologies, this embodiment, by stopping the opening of a silent window for a PON channel when the OLT detects that the PON channel meets the window closing conditions, can significantly reduce the number of silent window operations, thereby reducing data transmission latency and jitter for normally operating ONUs, and improving the uplink transmission quality of ONUs.

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] The silent window setting method, apparatus, device, storage medium, and program product provided in this application embodiment can be applied to the scenario of setting a silent window during data transmission between the OLT and ONU in PON, and of course, it can also be applied to other scenarios.

[0044] Figure 1 This is a schematic diagram illustrating an application scenario for a method of setting a silent window provided in an embodiment of this application. For example... Figure 1 As shown, this application scenario may include an OLT 101 and multiple ONUs 103, with an optical distribution network (ODN) 103 positioned between the OLT 101 and the ONUs 103. Data transmission between the OLT 101 and any ONU 103 is achieved via the ODN.

[0045] In related technologies, during the ONU registration and activation state machine cycle in the PON standard protocol, the OLT needs to periodically provide a silent window for the ONU at fixed intervals (e.g., 2 seconds) so that offline ONUs and ONUs with specified ranging can report the corresponding signaling messages to the OLT within the time period corresponding to the silent window.

[0046] However, normal data transmission of a normally functioning ONU is suppressed, preventing data transmission within the time period corresponding to the silent window. This increases the data transmission latency of a normally functioning ONU. For example, data transmission from a normally functioning ONU will introduce a latency equal to at least the length of the silent window.

[0047] Figure 2 This is a schematic diagram of a periodic silent window in related technologies, such as... Figure 2 As shown, during the silent window period 1, ONU X, which is not online (or not connected to the network), can report signaling messages, but the uplink transmissions of ONU A, ONU B, and ONU C, which are already online (or connected to the network), are suppressed. The silent window duration in the standard protocol can be 250ms.

[0048] During the silent window 2 period, uplink transmissions of ONU A, ONU B, ONU C, and ONU X that are already online are suppressed. The standard protocol allows a 2-second interval between silent window 1 and silent window 2.

[0049] Based on the aforementioned related technologies, this application provides a method for setting a silent window. By stopping the opening of a silent window for a PON channel when the PON channel meets the window closing conditions based on the status of each ONU corresponding to the PON channel, the number of silent windows for the PON channel can be significantly reduced. This can reduce the data transmission latency and data transmission jitter of the normally operating ONUs corresponding to the PON channel, and is beneficial to improving the uplink transmission quality of the ONUs corresponding to the PON channel.

[0050] It should be noted that the beneficial effects or technical problems solved by the embodiments of this application are not limited to this one, but may also be other implicit or related problems. For details, please refer to the description of the embodiments below.

[0051] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0052] In one embodiment, Figure 3 This is a flowchart illustrating a method for setting a silent window in one embodiment of this application. In this embodiment, the method is applied to... Figure 1 Let's take the OLT in the example to illustrate. Figure 3 As shown, the method in this application embodiment may include the following steps:

[0053] Step S301: If the passive optical fiber network (PON) channel of the optical line terminal (OLT) meets the window closing conditions, stop opening a silent window for the PON channel.

[0054] The silent window involved in this application embodiment can be used to activate the online status of the Optical Network Unit (ONU), that is, an ONU that is not online can report the corresponding signaling messages to the OLT within the time period corresponding to the silent window. Of course, the silent window involved in this application embodiment can also be used for ONU ranging information reporting (that is, an ONU with specified ranging can report the corresponding signaling messages to the OLT within the time period corresponding to the silent window), etc., and will not be described in detail in this application embodiment.

[0055] For example, the duration of the silent window in this application embodiment may be the same as or different from the duration of the silent window in the standard protocol.

[0056] The OLT involved in the embodiments of this application may include at least one PON channel, and each PON channel may connect to at least one ONU.

[0057] For example, the window closing conditions in this application embodiment may include, but are not limited to: all ONUs corresponding to the PON channel are online, or the number of times a silent window is provided for the PON channel exceeds a preset threshold (e.g., 4 or 5). It should be understood that the number of times a silent window is provided for the PON channel in this application embodiment may refer to the number of times the OLT provides a silent window for the PON channel during this round of activation.

[0058] It should be noted that when the OLT opens a silent window for the PON channel, it can periodically provide a silent window for each ONU corresponding to the PON channel at a preset interval (e.g., 2 seconds) until it stops opening a silent window for the PON channel.

[0059] It should be noted that the example values ​​corresponding to the preset number threshold and / or preset interval involved in the embodiments of this application are illustrative. Of course, different values ​​can be set according to the actual network conditions.

[0060] Considering that the PON channels in the current PON network do not always have an unconnected ONU that needs to provide a silent window, in this step, the OLT can stop opening a silent window for any passive fiber network PON channel of the optical line terminal OLT when the window closing condition is met.

[0061] It should be noted that if the OLT stops opening a silent window for a PON channel, it will not provide a silent window for each ONU corresponding to that PON channel.

[0062] For example, the OLT can set the silent window of the PON channel to the closed state, thus preventing the ONUs corresponding to the PON channel from having a silent window. Of course, the OLT can also stop the silent window from being opened for the PON channel in other ways.

[0063] For example, suppose the OLT can include PON channel 1 and PON channel 2. The silent window of PON channel 1 and PON channel 2 is currently in the open state (that is, the silent window is periodically provided to each ONU of the corresponding PON channel at a preset interval). If the OLT detects that PON channel 1 meets the window closing condition, the OLT can change the silent window of PON channel 1 from the open state to the closed state, thereby stopping the opening of the silent window for PON channel 1.

[0064] As can be seen, in this embodiment of the application, by stopping the opening of a silent window for any passive optical fiber network PON channel when the OLT detects that the window closing condition is met, the number of silent windows can be greatly reduced, thereby reducing the delay and jitter impact on the data transmission of normally functioning ONUs.

[0065] In summary, in this embodiment, when the passive optical network (PON) channel of the optical line terminal (OLT) meets the window closing conditions, the silent window for that PON channel is stopped; wherein, the silent window is used to activate the optical network unit (ONU) upon online operation. It is evident that, compared to related technologies, this embodiment, by stopping the opening of a silent window for the PON channel when the OLT detects that the PON channel meets the window closing conditions, can significantly reduce the number of silent windows, thereby reducing data transmission latency and jitter for normally operating ONUs, and improving the uplink transmission quality of ONUs.

[0066] In one embodiment, Figure 4 This is a flowchart illustrating the method for setting a silent window in another embodiment of this application. Based on the above embodiments, this application describes the relevant content for determining whether a PON channel meets the conditions for closing the window. For example... Figure 4 As shown, the method in this application embodiment may further include the following steps:

[0067] Step S300: Determine whether the PON channel meets the window closing condition based on the status of each ONU corresponding to the PON channel.

[0068] In this embodiment of the application, the OLT can detect the status of each ONU corresponding to any PON channel. The status of any ONU may include, but is not limited to, being offline or online.

[0069] In this step, the OLT can determine whether the PON channel meets the window closing condition based on the status of each ONU corresponding to any PON channel with the silent window in the open state. This allows the OLT to promptly stop opening the silent window for the PON channel when it is determined that the PON channel meets the window closing condition, which can significantly reduce the number of silent windows and thus reduce the delay and jitter impact on the data transmission of normally operating ONUs.

[0070] In one possible implementation, if all ONUs corresponding to the PON channel are online, the OLT can determine that the PON channel meets the window closing condition and there is no need to provide a silent window for the PON channel.

[0071] In a real PON network, if the optical fiber connection of an ONU that is not online is normal, the ONU will usually come online quickly within a small number of silent windows; if the optical fiber connection of the ONU is abnormal and there is an optical link failure, the ONU will still be unable to come online even within a large number of silent windows.

[0072] In another possible implementation, if some ONUs corresponding to the PON channel are offline and the number of times a silent window is provided for the PON channel exceeds a preset threshold, the OLT can determine that the PON channel meets the window closing condition and there is no need to provide a silent window for the PON channel.

[0073] As can be seen, in this implementation, the OLT can determine that if some ONUs corresponding to the PON channel may have optical link failures by detecting that the number of times a silent window is provided for the PON channel exceeds a preset threshold, even if some ONUs corresponding to the PON channel are offline, the PON channel meets the window closing condition and there is no need to provide a silent window for the PON channel. This is to reduce the delay and jitter impact on the data transmission of normally functioning ONUs corresponding to the PON channel.

[0074] Optionally, if some ONUs corresponding to any PON channel are offline and the number of times a silent window is provided for the PON channel does not exceed a preset threshold, the OLT can, after a first preset time interval (e.g., 2 seconds), re-determine whether the PON channel meets the window closing condition based on the status of each ONU corresponding to the PON channel. This is so that if the PON channel meets the window closing condition, the silent window for the PON channel can be stopped in a timely manner.

[0075] It should be noted that the example values ​​corresponding to any preset duration involved in the embodiments of this application are illustrative only. Of course, different values ​​can be set according to the actual network conditions.

[0076] In summary, in this embodiment, by determining whether the PON channel meets the window closing condition based on the status of each ONU corresponding to the PON channel, a silent window is stopped when the PON channel is detected to meet the window closing condition. This significantly reduces the number of silent windows for the PON channel, thereby reducing the data transmission latency and jitter of the normally operating ONUs corresponding to the PON channel, which is beneficial to improving the uplink transmission quality of the ONUs corresponding to the PON channel.

[0077] In one embodiment, Figure 5 This is a flowchart illustrating the method for setting a silent window in another embodiment of this application. Based on the above embodiments, this application describes the relevant content of re-opening a silent window for a PON channel. For example... Figure 5 As shown, the method in this application embodiment may further include the following steps:

[0078] Step S302: After the second preset duration of the silent window for the PON channel is stopped, determine whether the PON channel meets the window opening conditions.

[0079] For example, the windowing conditions involved in the embodiments of this application may include, but are not limited to: some ONUs corresponding to the PON channel are in an offline state.

[0080] In this step, after the OLT stops opening a silent window for any PON channel for a second preset duration (e.g., 1 minute), it can determine whether the PON channel meets the window opening conditions, so that if the PON channel meets the window opening conditions, it can open a silent window for the PON channel in a timely manner.

[0081] Optionally, the OLT can determine whether the PON channel meets the windowing conditions based on the status of each ONU corresponding to the PON channel.

[0082] In one possible implementation, if some ONUs corresponding to the PON channel are offline, the OLT can determine that the PON channel meets the windowing conditions and needs to provide a silent window for the PON channel.

[0083] In another possible implementation, if all ONUs corresponding to the PON channel are online, the OLT can determine that the PON channel does not meet the windowing conditions and there is no need to provide a silent window for the PON channel.

[0084] Optionally, if all ONUs corresponding to the PON channel are online, the OLT can re-determine whether the PON channel meets the windowing conditions after a third preset time interval (e.g., 1 minute) based on the status of each ONU corresponding to the PON channel. This allows the OLT to promptly open a silent window for the PON channel if the windowing conditions are met.

[0085] Step S303: If the PON channel meets the windowing conditions, open a silent window for the PON channel.

[0086] In this step, if any PON channel meets the windowing conditions, the OLT can open a silent window for that PON channel. This allows the OLT to periodically provide silent windows for each ONU corresponding to that PON channel at preset intervals (e.g., 2 seconds), so that the offline ONUs and the ONUs with specified ranging corresponding to that PON channel can report the corresponding signaling messages to the OLT within the time period corresponding to the silent window.

[0087] For example, the OLT can set the silent window of the PON channel to the open state, thereby providing a silent window periodically to each ONU corresponding to the PON channel at preset intervals (e.g., 2 seconds). Of course, the OLT can also open the silent window for the PON channel in other ways.

[0088] It should be understood that after the OLT opens a silent window for the PON channel, it can continue to return to step S300 to stop opening a silent window for the PON channel if it is determined that the PON channel meets the window closing conditions.

[0089] In summary, in this embodiment, by stopping the opening of a silent window for a second preset duration, it can be determined whether the PON channel meets the windowing conditions. If the PON channel meets the windowing conditions, a silent window is opened for the PON channel. Therefore, this embodiment achieves on-demand opening of silent windows. Opening silent windows for PON channels that require silent window opening not only meets the ONU registration and activation requirements but also significantly reduces the number of silent window operations, thereby improving the uplink transmission quality of the ONU.

[0090] It should be noted that the order in which the OLT determines whether a PON channel meets the window closing condition and the order in which it determines whether a PON channel meets the window opening condition is not limited. For example, the OLT can first determine whether the PON channel meets the window closing condition, then determine whether the PON channel meets the window opening condition, and then return to determine whether the PON channel meets the window closing condition again, and so on, in a loop. Alternatively, the OLT can first determine whether the PON channel meets the window opening condition, then determine whether the PON channel meets the window closing condition, and then return to determine whether the PON channel meets the window opening condition again, and so on, in a loop.

[0091] In one embodiment, Figure 6 This is a flowchart illustrating the method for setting a silent window in another embodiment of this application. Based on the above embodiments, this application uses a partial ONU optical link failure in a PON channel as an example to introduce the overall process of setting a silent window. Figure 6 As shown, the method in this application embodiment may further include the following steps:

[0092] Step S601: The OLT determines whether the PON channel meets the window closing condition based on the status of each ONU corresponding to the PON channel.

[0093] For example, the window closing conditions in the embodiments of this application may include, but are not limited to: all ONUs corresponding to the PON channel are online, or the number of times a silent window is provided for the PON channel exceeds a preset threshold.

[0094] If the PON channel meets the window closing condition, then proceed to step S602; if the PON channel does not meet the window closing condition, then return to step S601 again after a first preset time interval.

[0095] It should be understood that due to optical link failures of some ONUs in this PON channel, even though the OLT has provided a silent window for this PON channel more than the preset threshold number of times, some ONUs are still not online.

[0096] Step S602: The OLT stops opening a silent window for this PON channel.

[0097] Furthermore, after the OLT stops opening the silent window for the PON channel for the second preset duration, it can execute step S603 so that it can be brought online in a timely manner when the ONU optical link of the PON channel returns to normal. (Off state)

[0098] Step S603: The OLT determines whether the PON channel meets the windowing conditions based on the status of each ONU corresponding to the PON channel.

[0099] For example, the windowing conditions in the embodiments of this application may include, but are not limited to: some ONUs corresponding to the PON channel are in an offline state.

[0100] If the PON channel meets the windowing conditions, then proceed to step S604; if the PON channel does not meet the windowing conditions, then return to step S603 again after a third preset time interval.

[0101] Step S604: The OLT opens a silent window for the PON channel.

[0102] Furthermore, after the OLT opens a silent window for the PON channel, it can execute step S601.

[0103] In one embodiment, Figure 7 This is a flowchart illustrating the method for setting a silent window in another embodiment of this application. Based on the above embodiments, this embodiment of the application takes the normal operation of each ONU optical link in any PON channel as an example to introduce the overall process of setting a silent window. Figure 7 As shown, the method in this application embodiment may further include the following steps:

[0104] Step S701: The OLT determines whether the PON channel meets the windowing conditions based on the status of each ONU corresponding to the PON channel.

[0105] For example, the windowing conditions in the embodiments of this application may include, but are not limited to: some ONUs corresponding to the PON channel are in an offline state.

[0106] If the PON channel meets the windowing conditions, then step S702 is executed; if the PON channel does not meet the windowing conditions, then after a third preset time interval, step S701 is executed again.

[0107] Step S703: The OLT opens a silent window for the PON channel.

[0108] Furthermore, after the OLT opens a silent window for the PON channel, it can execute step S704.

[0109] Step S704: The OLT determines whether the PON channel meets the window closing condition based on the status of each ONU corresponding to the PON channel.

[0110] If the PON channel meets the window closing condition, then step S705 is executed; if the PON channel does not meet the window closing condition, then after a first preset time interval, step S704 is executed again.

[0111] Step S705: OLT stops opening a silent window for this PON channel.

[0112] Optionally, after the OLT stops opening the silent window for the PON channel for a second preset duration, it can also perform step S701.

[0113] In summary, in the above embodiments of this application, by opening silent windows for PON channels that require silent windows based on the status of each ONU corresponding to the PON channel, and stopping the opening of silent windows for PON channels that do not require silent windows, the silent window can be dynamically set according to the status of each ONU corresponding to the PON channel. This can significantly reduce the number of silent windows, thereby improving the uplink transmission quality of the ONU.

[0114] It should be understood that, although Figure 3-7 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order in which these steps are executed, and they can be performed in other orders. Furthermore, Figure 3-7 At least some of the steps in the process may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least some of the steps or stages in other steps.
