[0024] In the following description, specific details are set forth in order to provide a thorough understanding of embodiments of the application. However, persons having ordinary skill in the art will readily recognize that embodiments of the application can be practiced without

[0025] It should be noted that although the logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in an order different from the flowchart. The terms "first", "second", and the like in the specification and claims and the above-described drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0026] It should also be understood that, in the description of the embodiments of the present application, the reference "one embodiment" or "some embodiments" or the like means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment", "in some embodiments", "in other embodiments", "in additional embodiments" and so on, in various places in the specification are not necessarily all referring to the same embodiment, unless otherwise specified. The terms "comprising", "including", "having" and their variants, mean "including but not limited to", unless otherwise specified.

[0027] At present, remote office, remote education, e-commerce, Internet of Things, ultra-high definition (4K / 8K) live broadcast, cloud game and industrial robot control have become current popular businesses, promoting the development and construction of gigabit networks. In addition to the operator and user's desire for higher network access rate and more efficient bandwidth utilization, there is also a higher requirement for network latency and jitter. In particular, in the time sensitive network (TSN), higher requirements are put forward for the latency and jitter guarantee of the time sensitive (TSN) service of the industrial PON (Passive Optical Network).

[0028] DBA (dynamic bandwidth assignment) is a mechanism in which the OLT (Optical Line Terminal) of the GPON family standard ITU-T G.984.3 / ITU-T G.987.3 dynamically allocates uplink bandwidth to the ALLOC-ID of the ONU (Optical Network Unit) according to the SR-status report of the dynamic buffer status of each ALLOC-ID actively reported by the ONU, or the actual dynamic traffic (Non-SR) of each ALLOC-ID monitored by the OLT.

[0029] However, the uplink latency of the traditional GPON family system is limited by one frame (125us), and the DBA mechanism of the traditional GPON family system results in an uplink latency of usually more than 125us, which is far from meeting the current demand. Moreover, the traditional fixed bandwidth (FBA, Fixed Bandwidth Assignment) scheduling cannot effectively utilize the uplink bandwidth on demand due to its fixed bandwidth size.

[0030] Based on this, the embodiment of the present application provides a bandwidth scheduling method, an electronic device and a computer readable storage medium, by introducing the concept of subframe, and by dividing the service area of different priority in the subframe, combining the characteristics of fixed bandwidth allocation and dynamic bandwidth allocation, the different services are carried in detail, the different requirements of different services on bandwidth, delay and jitter are met, the bottleneck of the traditional GPON family system that the delay is greater than 125us is broken, the delay and jitter of the corresponding service are significantly reduced, and the maximum effective utilization of bandwidth is realized.

[0031] The embodiment of the present application can at least solve the technical problem of high delay of the wideband scheduling scheme in the related art.

[0032] The bandwidth scheduling method, the electronic device and the computer readable storage medium provided by the embodiment of the present application are specifically explained by the following embodiment, first, the bandwidth scheduling method in the embodiment of the present application and the application environment thereof are described.

[0033] Referring to FIG. 1, FIG. 1 is a schematic diagram of an application environment related to a bandwidth scheduling method provided by the embodiment of the present application, as shown in FIG. 1, the application environment of the embodiment of the present application is mainly a networking architecture of GPON family system using time division multiplexing technology for uplink bandwidth allocation, the networking architecture includes OLT (Optical Line Terminal), ODN (Optical Distribution Network), ONU (Optical Network Unit), ONT (Optical network terminal), MDU (Multiple Dwelling Unit) and the like.

[0034] It should be further explained that the GPON system belongs to a point to multiple point (P2MP) architecture, and the uplink usually adopts time division multiplexing (TDM) technology. The OLT is responsible for allocating uplink bandwidth time slots for the ONU, and the ONU can only send uplink data in the time slot allocated by the OLT, as shown in FIG. 2 and FIG. 3.

[0035] Referring to FIG. 4, FIG. 4 is a flowchart of a bandwidth scheduling method provided by the embodiment of the present application, the bandwidth scheduling method can be applied to an electronic device, as shown in FIG. 4, the bandwidth scheduling method provided by the embodiment includes steps S10 to S50.

[0036] Step S10, dividing a target frame into a plurality of subframes according to a preset bandwidth requirement; wherein each subframe corresponds to a subframe configuration table and a high priority entry configuration table respectively;

[0037] In the embodiment, the execution subject is an optical line terminal (OLT) in the networking architecture, the preset bandwidth requirement is determined by the related service, and the target frame, i.e., a frame that needs to be scheduled, can be a next frame of a current frame or any frame after the current frame.

[0038] As an example, the related service can be a TSN service. After the preset bandwidth requirement is determined, the optical line terminal can configure a subframe configuration table as shown in FIG. 6 and a high-priority entry configuration table as shown in FIG. 7 based on the bandwidth requirement, and then flexibly divide the target frame to be processed into a number of subframes and high-priority time slot regions according to the information contained in the two configuration tables. Each subframe corresponds to a subframe configuration table and a high-priority entry configuration table respectively. The two configuration tables contain information such as the serial number of the corresponding subframe, an end-of-frame flag, the number of high-priority bandwidth entries, the start and end positions of the sub-priority and low-priority regions, a subframe start flag, a subframe end flag, and high-priority entry content. It can be understood that the table entry content in the subframe configuration table in FIG. 6 and the high-priority entry configuration table in FIG. 7 is only an example. Other configuration tables with similar functions can also be flexibly configured on this basis. These configuration tables that are basically consistent with the concept of the embodiment should all belong to the protection scope of the embodiment.

[0039] As an example, with reference to FIGS. 5 to 9, in the embodiment, for high-priority service T-CONT (Traffic Container, Ethernet transmission service capacity), the bandwidth time slots are allocated in the high-priority region (light region in FIG. 5), and the FBA mechanism is used for scheduling to achieve multiple bursts at a fixed time within a frame (note that the number of bursts within a frame is less than or equal to the number of divided subframes within a frame), thereby breaking through the bottleneck that the traditional DBA uplink delay is greater than one frame (125 us). At the same time, when the target frame is divided into multiple subframes, the TSN service characteristics can be combined to flexibly adjust the division of the subframes and their time slot regions, and the bandwidth entry time slots of the FBA (the bandwidth entry content and format are shown in FIGS. 8 and 9) are configured to match the TSN service, thereby minimizing the delay and jitter (the minimum delay can be reduced to about 10 us). For ordinary service T-CONT, the bandwidth time slots are allocated in the non-high-priority region (dark region in FIG. 5), and the traditional DBA mechanism is used for scheduling to achieve maximum effective utilization of bandwidth.

[0040] In step S20, the available bandwidth of the target frame is calculated according to the information collected by the optical network.

[0041] In the embodiment, the optical network collection information can include DBRU (dynamic bandwidth report uplink, used for reporting the status of T-CONT, in order to apply bandwidth next time, complete dynamic bandwidth allocation of ONU) reported by ONU or dynamic traffic monitored by OLT side. In the case that the OLT obtains any one of the above optical network collection information, the OLT can calculate the bandwidth allocated to the target frame, i.e. the allocable bandwidth, and the allocable bandwidth is used to calculate the non-high priority bandwidth entry.

[0042] In step S30, the bandwidth entry priority of the target subframe is determined according to the high priority entry configuration table of the target subframe, the subframe configuration table and the allocable bandwidth of the target subframe.

[0043] In the embodiment, the OLT performs bandwidth scheduling on each subframe in the target frame in turn. The embodiment takes one subframe in the multiple subframes, i.e. the target subframe, as an example. Before the bandwidth scheduling, the bandwidth entry priority order of the target subframe, i.e. the high priority bandwidth entry, the sub-priority bandwidth entry and the low priority bandwidth entry, is determined according to the information obtained in the foregoing steps.

[0044] In step S40, the bandwidth entries of the target subframe are sequentially carried into the preset bandwidth mapping table according to the bandwidth entry priority of the target subframe.

[0045] In the embodiment, after the bandwidth entry priority order of the target subframe is determined, the high priority bandwidth entry, the sub-priority bandwidth entry and the low priority bandwidth entry are sequentially carried into the BWMAP table (i.e. the preset bandwidth mapping table, Bandwidth Management MAP) according to the order. Through the BWMAP table, the network administrator can monitor and control different types of traffic to ensure that the key applications and services obtain the necessary bandwidth and priority.

[0046] In step S50, in the case that the target subframe is the last subframe of the target frame, all the bandwidth entries of the target frame stored in the bandwidth mapping table are sent to the optical network unit.

[0047] It should be noted that in the embodiment, the OLT starts to send the bandwidth entries belonging to the frame stored in the BWMAP table to the optical network unit ONU only after completing the bandwidth scheduling on all the subframes in the frame.

[0048] In some possible embodiments, the above step S30 can include: step S31, determining the high priority bandwidth entry of the target subframe according to the high priority entry configuration table of the target subframe; and step S32, determining the non-high priority bandwidth entry of the target subframe according to the subframe configuration table and the allocable bandwidth of the target subframe.

[0049] In some possible embodiments, the step S31 can include: a step S311 of extracting the high-priority entry content of the target subframe from the high-priority entry configuration table of the target subframe; and a step S312 of determining the high-priority bandwidth entry of the target subframe based on the high-priority entry content.

[0050] In some possible embodiments, the step S32 can include: a step S321 of obtaining the bandwidth slot of the non-high-priority area in the target subframe from the subframe configuration table of the target subframe; and a step S322 of calculating the non-high-priority bandwidth entry of the target subframe based on the bandwidth slot of the non-high-priority area and the allocatable bandwidth.

[0051] It can be understood that, in the present embodiment, the OLT can determine the high-priority entry content of the target subframe by querying the high-priority entry configuration table shown in FIG. 7, and then determine the high-priority bandwidth entry of the target subframe; the OLT can obtain the bandwidth slot of the non-high-priority (for example, the suboptimal and low-priority) area in the target subframe by querying the subframe configuration table shown in FIG. 6, according to the position of the end of the suboptimal and low-priority area in the target subframe and the position of the start of the suboptimal and low-priority area in the target subframe, and then determine the non-high-priority bandwidth entry (for example, the suboptimal and low-priority bandwidth entry) of the target subframe by combining the bandwidth slot of the non-high-priority area and the allocatable bandwidth calculated in the foregoing step.

[0052] Referring to FIG. 10, in some possible embodiments, after the step S40, the bandwidth scheduling method can further include: a step S41 of determining whether the target subframe is the last subframe of the target frame according to the subframe configuration table or the high-priority entry configuration table of the target subframe; and a step S42 of performing bandwidth scheduling on a next subframe located after the target subframe in the target frame in a case where the target subframe is not the last subframe of the target frame.

[0053] It can be understood that, since the OLT will start sending the bandwidth entries belonging to the frame and stored in the BWMAP table to the optical network unit ONU only after completing the bandwidth scheduling on all the subframes in the frame, if the target subframe is not the last subframe in the frame, it is necessary to continue performing bandwidth scheduling on other subframes in the target frame, until completing the bandwidth scheduling on all the subframes in the frame, and then performing the step S50, that is, starting to send the bandwidth entries belonging to the frame and stored in the BWMAP table to the optical network unit ONU.

[0054] In some possible embodiments, the step of performing bandwidth scheduling on the next subframe after the target subframe in the target frame in step S42 can include: step S421, determining bandwidth entry priorities of the next subframe according to the high-priority entry configuration table, the subframe configuration table and the allocatable bandwidth of the next subframe; step S422, sequentially transferring the bandwidth entries of the next subframe to the bandwidth mapping table according to the bandwidth entry priorities of the next subframe; and step S423, determining whether the next subframe is the last subframe of the target frame.

[0055] In some possible embodiments, after step S40, the bandwidth scheduling method can further include: step S51, performing bandwidth scheduling on a next frame of the target frame in a case where the target subframe is the last subframe of the target frame.

[0056] In some possible embodiments, the step of performing bandwidth scheduling on the next frame of the target frame in step S51 can include: step S511, taking the next frame of the target frame as a new target frame, and performing the step of dividing the target frame into a plurality of subframes according to the preset bandwidth requirement.

[0057] It can be understood that, in this embodiment, the bandwidth scheduling method for the next subframe of the target subframe is basically the same as the bandwidth scheduling method for the target subframe, and the difference lies in that the subframe configuration table and the high-priority bandwidth entry configuration table corresponding to different subframes are also different.

[0058] As an example, the overall implementation process of each of the above embodiments can be understood in combination with FIG. 11. The processes in FIG. 11 are basically the same as the steps mentioned in the above embodiments, and will not be described here again.

[0059] In addition, the bandwidth scheduling method provided in this embodiment can be evolved to generate bandwidth entries of multiple frames at a time, or completely adjust the service configuration through an external module or device. These improved schemes that are basically the same as the technical concept of the bandwidth scheduling method provided in this embodiment should also belong to the protection scope of this embodiment.

[0060] The embodiment provides a bandwidth scheduling method. By introducing the concept of a subframe, and by dividing different-priority service areas in the subframe, the characteristics of fixed bandwidth allocation and dynamic bandwidth allocation are combined to finely carry different services, meet different requirements of different services on bandwidth, time delay and jitter, break through the bottleneck that the time delay of a traditional GPON system is greater than 125 us, significantly reduce the time delay and jitter of corresponding services, and realize maximum effective utilization of bandwidth.

[0061] The embodiment can be applied in a GPON / XGPON / XGSPON / HSPON (50GPON) system, and can break through the bottleneck that the uplink service time delay of a traditional GPON system is higher than 125us, and can significantly reduce the jitter of the uplink service of the GPON system, and can use a flexible and efficient uplink transmission scheduling method to adapt to different requirements of the user on the time delay, jitter and bandwidth of the corresponding service.
