Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a load balancing method, apparatus and storage medium. Background Technology

[0002] To enhance network robustness, optical line terminals (OLTs) typically employ a dual uplink networking mode. This mode involves one OLT connecting to two broadband access servers (BAS): a primary BAS and a backup BAS. This way, if the primary BAS fails or the primary link between the primary BAS and the OLT fails, user equipment accessing the OLT can continue service transmission through the backup BAS.

[0003] However, when the primary BAS or primary link is repaired, user equipment that transmits services through the backup BAS cannot switch to the primary BAS in a timely manner, resulting in an imbalance of load between the primary BAS and the backup BAS.

[0004] Currently, the load on the primary and backup BAS is usually adjusted manually. However, manual verification is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0049] To facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish the same or similar items with essentially the same function and effect. Those skilled in the art can understand that the terms "first" and "second" are not intended to limit the quantity or execution order.

[0050] As described in the background section, OLTs typically employ a dual-uplink networking mode. This mode means that one OLT connects to two BASs: a primary BAS and a backup BAS. This allows user equipment accessing the OLT to continue service transmission via the backup BAS when the primary BAS fails or the primary link between the primary BAS and the OLT fails.

[0051] However, when the primary BAS or primary link is repaired, user equipment transmitting services through the backup BAS cannot switch to the primary BAS in a timely manner, resulting in an imbalance in load between the primary and backup BAS. In this situation, the network utilization of the primary BAS is low, while the network utilization of the backup BAS is high, thus wasting network resources.

[0052] Currently, the load on the primary and backup BAS is usually adjusted manually. However, manual verification is not timely, resulting in poor user experience. Furthermore, manual verification is time-consuming, labor-intensive, and costly.

[0053] To address the aforementioned problems, this application provides a load balancing method in which an electronic device can obtain first load information and second load information. The first load information is the load information of a first access server; the second load information is the load information of a second access server; and the first and second access servers are any two of a plurality of access servers connected to a target OLT. In this way, when the first and second load information do not meet the load balancing conditions, the electronic device can adjust the latency parameters of the first or second access server to ensure that the first and second load information meet the load balancing conditions. This achieves load balancing without manual verification, effectively distributing the traffic carried by different access servers, avoiding network congestion, and improving network utilization.

[0054] Secondly, electronic devices can adjust the latency parameters of the first or second access server to ensure that the first and second load information meet the load balancing conditions. This eliminates the need for manual verification, reduces labor costs, and significantly shortens the processing time compared to manual processing. This improves the timeliness of load balancing and also enhances the user experience by quickly resolving network failures caused by load imbalance.

[0055] This load balancing method is applicable to load balancing systems. Figure 1 One structure of this load balancing system is shown. For example... Figure 1 As shown, the load balancing system includes: OLT101, multiple access servers 102 ( Figure 1(Taking two access servers 102 as an example) and electronic devices 103.

[0056] Among them, OLT101 is communicatively connected to multiple access servers 102, and electronic device 103 is communicatively connected to OLT101 and multiple access servers 102 respectively.

[0057] The OLT101 is a terminal device used to connect fiber optic trunk lines. The OLT101 is used to convert passive optical network signals from user terminals into electrical signals used by the operator's equipment, and to coordinate multiplexing between optical network units.

[0058] In this embodiment of the application, OLT101 is used to convert the passive optical network signal of the user terminal into an electrical signal and send the electrical signal to the access server.

[0059] In practical applications, OLT101 includes multiple OLT ports, each of which is used to connect to an access server 102. Figure 1 The following explanation uses OLT101, which includes two OLT ports, as an example, where OLT101 connects to two access servers 102.

[0060] Access server 102 is a user access service device set up in the network aggregation layer. It can intelligently realize user aggregation, authentication, billing and other services, and can also conveniently provide a variety of IP value-added services according to user needs.

[0061] In this embodiment of the application, the access server 102 is used to receive the electrical signal sent by the OLT101 and process the electrical signal to obtain the service information required by the user.

[0062] In practical applications, the access server 102 includes multiple access server ports, each of which is used to connect to an OLT. Figure 1 The following explanation will be based on the example of access server 102 having one port, i.e., access server 102 connecting to OLT101.

[0063] Optionally, the access server 102 can be a BAS or a Broadband Remote Access Server (BRAS). The electronic device 103 is used to obtain the load information of each access server 102, and when the load information of two access servers 102 does not meet the load balancing conditions, adjust the latency parameter of one access server 102 so that the load information of the two access servers 102 meets the load balancing conditions.

[0064] Optionally, the physical device of electronic device 103 can be a server, a terminal, or other types of electronic devices; this application embodiment does not limit this. Optionally, when the physical device of electronic device 103 is a terminal, the terminal can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a radio access network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, or a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network, such as a mobile phone, tablet computer, laptop computer, netbook, or personal digital assistant (PDA).

[0065] Optionally, when the physical device of electronic device 103 is a server, the server can be one of the servers in a server cluster (composed of multiple servers), a chip in the server, a system-on-a-chip in the server, or a virtual machine (VM) deployed on a physical machine. This application embodiment does not limit this.

[0066] The basic hardware structure of electronic device 103 includes Figure 2 or Figure 3 The load balancing device shown includes the following components. Figure 2 and Figure 3 Taking the load balancing device shown as an example, the hardware structure of electronic device 103 is introduced.

[0067] like Figure 2 The diagram shown is a hardware structure schematic of a load balancing device provided in an embodiment of this application. The load balancing device includes a processor 21, a memory 22, a communication interface 23, and a bus 24. The processor 21, memory 22, and communication interface 23 are connected via the bus 24.

[0068] Processor 21 is the control center of the load balancing device. It can be a single processor or a collective term for multiple processing elements. For example, processor 21 can be a general-purpose central processing unit (CPU) or other general-purpose processors. Among them, the general-purpose processor can be a microprocessor or any conventional processor.

[0069] As one embodiment, processor 21 may include one or more CPUs, for example Figure 2CPU 0 and CPU 1 are shown in the diagram.

[0070] The memory 22 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and instructions, random access memory (RAM) or other type of dynamic storage device capable of storing information and instructions, or electrically erasable programmable read-only memory (EEPROM), disk storage media or other magnetic storage devices, or any other medium capable of carrying or storing desired program code in the form of instructions or data structures and accessible by a computer, but is not limited thereto.

[0071] In one possible implementation, the memory 22 can exist independently of the processor 21. The memory 22 can be connected to the processor 21 via a bus 24 and is used to store instructions or program code. When the processor 21 calls and executes the instructions or program code stored in the memory 22, it can implement the load balancing method provided in the following embodiments of this application.

[0072] In this embodiment, the software programs stored in the memory 22 of the electronic device 103 are different, so the functions implemented by the electronic device 103 are different. The functions performed by each device will be described with reference to the following flowchart.

[0073] In another possible implementation, the memory 22 can also be integrated with the processor 21.

[0074] Communication interface 23 is used for the load balancer to connect with other devices via a communication network, such as Ethernet, wireless access network, or wireless local area network (WLAN). Communication interface 23 may include a receiving unit for receiving data and a sending unit for sending data.

[0075] Bus 24 can be an industry standard architecture (ISA) bus, a peripheral component interconnect (PCI) bus, or an extended industry standard architecture (EISA) bus, etc. This bus can be divided into address bus, data bus, control bus, etc. For ease of representation, Figure 2The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.

[0076] Figure 3 Another hardware structure of the load balancing device in the embodiments of this application is shown. For example... Figure 3 As shown, the load balancing device may include a processor 31 and a communication interface 32. The processor 31 is coupled to the communication interface 32.

[0077] The functions of processor 31 can be referred to in the description of processor 21 above. In addition, processor 31 also has a storage function, and can perform the functions of memory 22 mentioned above.

[0078] Communication interface 32 is used to provide data to processor 31. This communication interface 32 can be an internal interface of the load balancer or an external interface of the load balancer (equivalent to communication interface 23).

[0079] It should be pointed out that, Figure 2 (or Figure 3 The structure shown in the diagram does not constitute a limitation on the load balancing device, except... Figure 2 (or Figure 3 In addition to the components shown in the diagram, the load balancing device may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0080] The load balancing method provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0081] The load balancing method provided in this application embodiment is applied to Figure 1 The electronic device 103 in the load balancing system shown is, for example Figure 4 As shown, the load balancing method provided in this application includes:

[0082] S401, The electronic device acquires the first load information and the second load information.

[0083] Wherein, the first load information is the load information of the first access server; the second load information is the load information of the second access server; the first access server and the second access server are any two of the multiple access servers connected to the OLT.

[0084] Specifically, in the dual-uplink networking mode of the OLT, the common technique is to manually check and adjust the load on the multiple access servers connected to the OLT. However, manual adjustment is inefficient. To improve load balancing efficiency, electronic devices can obtain load information corresponding to each of the multiple access servers connected to the OLT.

[0085] This application embodiment uses the OLT connecting two access servers as an example for illustration, that is, the electronic device can obtain the load information of the first access server (i.e., the first load information) and the load information of the second access server (i.e., the second load information).

[0086] The load information mentioned above can include the average traffic, maximum bandwidth, latency parameters, peak traffic, etc. of each access server.

[0087] Average traffic refers to the average downlink traffic transmitted by the access server to the OLT over a period of time.

[0088] Maximum bandwidth is used to indicate the maximum supported communication bandwidth between the OLT and the access server.

[0089] The latency parameter is used to represent the specific value of the response latency of the access server in responding to the user device's data request.

[0090] It should be understood that user equipment will prioritize access servers with lower latency parameters to obtain business data.

[0091] Peak traffic is used to represent the maximum downlink traffic that the access server transmits to the OLT within a certain period of time.

[0092] In one feasible approach, among multiple access servers connected to the OLT, each access server stores its own load information in its database. An electronic device can send a data retrieval request to each access server, requesting to retrieve the load information stored in each server's database.

[0093] Optional, combined Figure 1 The first access server can be Figure 1 One of the access servers is 102. Correspondingly, the second access server could be... Figure 1 Another access server 102 in the system.

[0094] S402. When the first load information and the second load information do not meet the load balancing conditions, the electronic device adjusts the latency parameters of the first access server or the second access server so that the first load information and the second load information meet the load balancing conditions.

[0095] Specifically, after acquiring the first load information and the second load information, the electronic device can determine whether the first load information and the second load information meet the load balancing conditions. When the first load information and the second load information do not meet the load balancing conditions, in order to balance the load on the first access server and the second access server, the electronic device can adjust the latency parameters of the first access server or the second access server.

[0096] It should be understood that when multiple user devices connected to the OLT transmit services, the OLT will prioritize the access server with lower latency to transmit the user device's service data. Therefore, when the load on the first access server is greater than the load on the second access server, the electronic device can increase the latency parameter of the first access server. In this way, the OLT will prioritize the second access server with lower latency to transmit the user device's service data.

[0097] In one possible implementation, when an electronic device adjusts the latency parameters of the first access server, it can send a parameter adjustment command to the first access server. This parameter adjustment command instructs the first access server to increase its own latency parameters.

[0098] Correspondingly, when the load on the second access server exceeds that of the first access server, the electronic equipment can increase the latency parameter of the second access server. In this way, the OLT will prioritize transmitting user equipment service data from the first access server, which has lower latency.

[0099] In one feasible approach, when the electronic device adjusts the latency parameters of the second access server, the specific implementation method of adjusting the latency parameters of the first access server can be referenced, which will not be elaborated here.

[0100] In one possible implementation, the electronic device can determine whether the first load information and the second load information meet the load balancing conditions based on the average traffic in the load information of each access server; it can also determine whether the first load information and the second load information meet the load balancing conditions based on the peak traffic in the load information of each access server; or it can determine whether the first load information and the second load information meet the load balancing conditions based on the ratio between the average traffic and the maximum bandwidth in the load information of each access server. The specific rules for determining the load balancing conditions are not limited in the embodiments of this application.

[0101] In some embodiments, the first load information includes: a first average traffic and a first maximum bandwidth; the second load information includes: a second average traffic and a second maximum bandwidth. In this case, the electronic device can accurately determine whether the first load information and the second load information meet the load balancing conditions based on the average traffic and maximum bandwidth included in the load information of each access server. Figure 4 ,like Figure 5 As shown in the embodiments of this application, the load balancing method further includes:

[0102] S501, The electronic device determines the ratio between the first average flow rate and the first maximum bandwidth as the first ratio.

[0103] Specifically, when determining whether the first load information and the second load information meet the load balancing conditions, the electronic device can determine the load of each access server based on the ratio between the average traffic and the maximum bandwidth of each access server, and then determine whether the first load information and the second load information meet the load balancing conditions based on the load of each access server. In this case, the electronic device can determine the ratio between the first average traffic and the first maximum bandwidth as the first ratio.

[0104] For example, suppose OLT-1 (i.e., the OLT in this application) has two uplink access servers, namely BAS-A (i.e., the first access server in this application) and BAS-B (i.e., the second access server in this application), the average traffic of BAS-A is U1 (i.e., the first average traffic in this application), and the maximum bandwidth is X1 (i.e., the first maximum bandwidth in this application), then the electronic device can determine the ratio between the average traffic of BAS-A and the maximum bandwidth as follows: (i.e., the first ratio in this application).

[0105] S502, The electronic device determines the ratio between the second average flow rate and the second maximum bandwidth as the second ratio.

[0106] Specifically, when determining whether the first load information and the second load information meet the load balancing conditions, the electronic device can determine the load of each access server based on the ratio between the average traffic and the maximum bandwidth of each access server, and then determine whether the first load information and the second load information meet the load balancing conditions based on the load of each access server. In this case, the electronic device can determine the ratio between the second average traffic and the second maximum bandwidth as the second ratio.

[0107] For example, assuming the average traffic of BAS-B is U2 (i.e., the second average traffic in this application) and the maximum bandwidth is X2 (i.e., the second maximum bandwidth in this application), the electronic device can determine the ratio between the average traffic of BAS-B and the maximum bandwidth as follows: (i.e., the second ratio in this application).

[0108] It should be noted that the electronic device does not impose any restrictions on the execution order of S501 and S502. The electronic device may execute S501 first and then S502; or it may execute S502 first and then S501; or it may execute S501 and S502 simultaneously.

[0109] S503. When the absolute value of the difference between the first ratio and the second ratio is greater than or equal to a preset threshold, the electronic device determines that the first load information and the second load information do not meet the load balancing conditions.

[0110] Specifically, after determining the first ratio and the second ratio, since the first ratio represents the load of the first access server and the second ratio represents the load of the second access server, the electronic device can determine whether the load of the first access server and the load of the second access server are close based on the absolute value of the difference between the first ratio and the second ratio, that is, whether the first load information and the second load information meet the load balancing conditions.

[0111] In this situation, when the absolute value of the difference between the first ratio and the second ratio is greater than or equal to a preset threshold, the electronic device determines that the first load information and the second load information do not meet the load balancing conditions.

[0112] Based on the above example, assuming a preset threshold of 20%, U1 = 5, and X1 = 10, the electronic device can determine the first ratio. The value is 0.5. Assuming U2 = 2 and X2 = 10, the electronic device can determine the second ratio. The value is 0.2. In this case, the electronic device can determine that the absolute value of the difference between the first ratio and the second ratio is 0.2.

[0113] It should be understood that 0.3 is greater than 20% (that is, the absolute value of the difference between the first ratio and the second ratio in this application is greater than or equal to the preset threshold). In this way, the electronic device can determine that the load of the first access server and the load of the second access server are significantly different, that is, the first load information and the second load information do not meet the load balancing conditions.

[0114] S504. When the absolute value of the difference between the first ratio and the second ratio is less than a preset threshold, the electronic device determines that the first load information and the second load information meet the load balancing condition.

[0115] Specifically, after determining the first ratio and the second ratio, since the first ratio represents the load of the first access server and the second ratio represents the load of the second access server, the electronic device can determine whether the load of the first access server and the load of the second access server are close based on the absolute value of the difference between the first ratio and the second ratio, that is, whether the first load information and the second load information meet the load balancing conditions.

[0116] In this case, when the absolute value of the difference between the first ratio and the second ratio is less than a preset threshold, the electronic device determines that the first load information and the second load information meet the load balancing condition.

[0117] Based on the above example, assuming U1 = 5, X1 = 10; U2 = 4, X2 = 10, then the electronic device can determine the first ratio. The ratio is 0.5; the second ratio The value is 0.4. In this case, the electronic device can determine that the absolute value of the difference between the first ratio and the second ratio is 0.4.

[0118] It should be understood that 0.1 is less than 20% (that is, the absolute value of the difference between the first ratio and the second ratio in this application is less than the preset threshold). In this way, the electronic device can determine that the load of the first access server and the load of the second access server are relatively similar, that is, the first load information and the second load information meet the load balancing condition.

[0119] In some embodiments, the relationship between the first ratio and the second ratio can represent the relationship between the load on the first access server and the load on the second access server. In this case, the electronic device can adjust the latency parameters of the first access server or the second access server based on the relationship between the first ratio and the second ratio. Figure 5 ,like Figure 6 As shown, in S402 above, the method for the electronic device to adjust the latency parameters of the first access server or the second access server specifically includes:

[0120] S601. When the first ratio is greater than the second ratio, the electronic device increases the latency parameter of the first access server by the target value.

[0121] Specifically, when the first ratio is greater than the second ratio, it indicates that the load on the first access server is greater than the load on the second access server. In this case, the electronic device can increase the latency parameter of the first access server by a target value.

[0122] Based on the above example, assuming the latency parameter of BAS-A is Z1 = 100 (i.e., the latency parameter of the first access server in this application), and the latency parameter of BAS-B is Z2 = 200 (i.e., the latency parameter of the second access server in this application), and assuming U1 = 5, X1 = 10; U2 = 4, X2 = 10, then the electronic device can determine the first ratio. Second ratio

[0123] It should be understood that 0.5 > 0.4, meaning the electronic device can determine... (That is, the first ratio in this application is greater than the second ratio), in which case the electronic device can increase Z1 by 300 (that is, the latency parameter of the first access server in this application is increased to the target value).

[0124] S602. When the first ratio is less than the second ratio, the electronic device increases the latency parameter of the second access server by the target value.

[0125] Specifically, when the first ratio is less than the second ratio, it indicates that the load on the first access server is less than the load on the second access server. In this case, the electronic device can increase the latency parameter of the second access server by the target value.

[0126] Based on the above example, assuming U1 = 5, X1 = 10; U2 = 6, X2 = 10, then the electronic device can determine the first ratio. Second ratio That is, electronic devices can determine (That is, the first ratio in this application is less than the second ratio). In this case, the electronic device can increase Z2 by 300 (that is, the latency parameter of the second access server in this application is increased to the target value).

[0127] In some embodiments, the electronic device can periodically determine whether the first load information and the second load information meet the load balancing conditions. When the electronic device determines in the first cycle that the first load information and the second load information do not meet the load balancing conditions, the electronic device can determine whether it is necessary to expand the communication network to which the target OLT belongs by checking the number of expansion warnings from the first access server or the second access server.

[0128] The number of expansion warnings indicates whether each access server needs to be expanded. The initial value for the number of expansion warnings for each access server is zero.

[0129] In this scenario, the first load information further includes: a first peak traffic volume and a first number of capacity expansion warnings; the second load information further includes: a second peak traffic volume and a second number of capacity expansion warnings. The first number of capacity expansion warnings represents the number of capacity expansion warnings issued by the first access server in the first period. The second number of capacity expansion warnings represents the number of capacity expansion warnings issued by the second access server in the first period. When the first load information and the second load information do not meet the load balancing conditions, the electronic device can also determine whether to expand the communication network to which the target OLT belongs based on the peak traffic volume and the number of capacity expansion warnings included in the load information of each access server. Figure 6 ,like Figure 7 As shown in the embodiments of this application, the load balancing method further includes:

[0130] S701, the electronic device determines the third capacity expansion warning number based on the first load information.

[0131] The third expansion warning number is used to indicate the number of expansion warnings issued by the first access server in the second cycle.

[0132] Specifically, since the first load information is used to represent the load of the first access server, the electronic device can determine the third expansion warning number based on the first load information.

[0133] In one feasible approach, when an electronic device determines the third capacity expansion warning count, it can do so based on the first peak traffic and the first maximum bandwidth in the first load information.

[0134] In another possible implementation, when determining the third capacity expansion warning number, the electronic device can also determine the third capacity expansion warning number based on the first peak traffic, the first maximum bandwidth, and the first average traffic in the first load information.

[0135] S702, the electronic device determines the fourth capacity expansion warning number based on the second load information.

[0136] The fourth expansion warning number is used to indicate the number of expansion warnings issued by the second access server in the second cycle.

[0137] Specifically, since the second load information is used to represent the load of the second access server, the electronic device can determine the fourth expansion warning number based on the second load information.

[0138] In one feasible approach, when an electronic device determines the fourth capacity expansion warning count, it can do so based on the second peak traffic and the second maximum bandwidth in the second load information.

[0139] In another possible implementation, when determining the fourth capacity expansion warning number, the electronic device can also determine the fourth capacity expansion warning number based on the second peak traffic, the second maximum bandwidth, and the second average traffic in the second load information.

[0140] It should be noted that the electronic device does not impose any restrictions on the execution order of S701 and S702. The electronic device may execute S701 first and then S702; or it may execute S702 first and then S701; or it may execute S701 and S702 simultaneously.

[0141] S703. When both the third and fourth expansion warning counts exceed the preset counts, the electronic device expands the communication network to which the target OLT belongs.

[0142] Specifically, when both the third and fourth capacity expansion warning counts exceed the preset counts, it indicates that the first and second access servers have experienced high loads over multiple periods. In this situation, the electronic device can expand the capacity of the communication network to which the target OLT belongs.

[0143] One possible approach to expanding the communication network to which the target OLT belongs can be to replace the optical fiber between the target OLT and the access server with a fiber with a higher bandwidth.

[0144] Another possible approach to expanding the communication network to which the target OLT belongs is to add a new access server to the target OLT.

[0145] Based on the above example, assume that the third expansion warning number for BAS-A is N3, and the fourth expansion warning number for BAS-B is N4. When N3 > 10 (i.e., the preset number in this application) and N4 > 10, the electronic device determines to expand the communication network to which the target OLT belongs.

[0146] Optionally, to prevent the number of expansion warnings from accumulating indefinitely, which would reduce the accuracy of expansion judgment, the electronic device can reset the number of expansion warnings for each access server to zero after several cycles (e.g., five cycles).

[0147] In some embodiments, combined with Figure 7 ,like Figure 8 As shown, in the above S701, the specific method for determining the third capacity expansion warning number based on the first load information of the electronic device includes:

[0148] S801, The electronic device determines the first value as the product of the first maximum bandwidth and the preset coefficient.

[0149] Specifically, the first load information includes a first maximum bandwidth. The first maximum bandwidth can represent the load capacity of the first access server. The electronic device determines a first value by multiplying the first maximum bandwidth by a preset coefficient, and this first value can be used to represent the load capacity of the first access server.

[0150] Based on the above example, assuming that the maximum bandwidth of BAS-A is X1 = 10 and the preset coefficient α = 0.8, the electronic device can determine α·X1 = 8 (i.e., the first value in this application).

[0151] S802. When the first peak flow rate is greater than or equal to the first value, the electronic device increases the first expansion warning number by the first preset value to obtain the third expansion warning number.

[0152] Specifically, since the aforementioned first value can represent the load capacity of the first access server, the electronic device can determine whether the load of the first access server exceeds its load capacity based on the first value and the magnitude of the first peak traffic. If the first peak traffic is greater than or equal to the first value, the electronic device can determine that the load of the first access server exceeds its load capacity. Therefore, the electronic device can determine that the communication network to which the target OLT belongs may need capacity expansion, and thus increase the first capacity expansion warning count by a first preset value to obtain a third capacity expansion warning count.

[0153] Based on the above example, assuming that the peak traffic of BAS-A is Y1 = 10 (i.e., the first peak traffic in this application), the number of expansion warnings is N1 = 0 (i.e., the first number of expansion warnings in this application), the maximum bandwidth is X1 = 10, and the preset coefficient α = 0.8, then the electronic device can determine α·X1 = 8.

[0154] It should be understood that 10>8, that is, Y1≥ɑ·X1 (that is, the first peak flow rate in this application is greater than or equal to the first value), then the electronic device can determine N3 (that is, the third expansion warning number obtained in this application) = N1+1 (that is, the first expansion warning number is increased by the first preset value in this application).

[0155] S803. When the first peak flow rate is greater than or equal to the first value and the first average flow rate is greater than or equal to the first value, the electronic device increases the first expansion warning number by the second preset value to obtain the third expansion warning number.

[0156] When the first peak traffic is greater than or equal to the first value and the first average traffic is greater than or equal to the first value, it indicates that the communication network to which the target OLT belongs urgently needs to be expanded. Therefore, the electronic device can increase the first expansion warning number to a larger second preset value, that is, the second preset value should be greater than the first preset value.

[0157] Specifically, since the aforementioned first value can represent the load capacity of the first access server, the electronic device can determine whether the load of the first access server exceeds its load capacity based on the first value, the first peak traffic, and the first average traffic. If the first peak traffic is greater than or equal to the first value, and the first average traffic is also greater than or equal to the first value, the electronic device can determine that the load of the first access server exceeds its load capacity. Therefore, the electronic device can determine that the communication network to which the target OLT belongs may urgently need expansion, and thus increase the first expansion warning count by a second preset value to obtain a third expansion warning count.

[0158] Based on the above example, assuming Y1 = 10, U1 = 9, the number of expansion warnings is N1 = 0, the maximum bandwidth is X1 = 10, and the preset coefficient α = 0.8, then the electronic device can be determined to have α·X1 = 8.

[0159] It should be understood that 10>8 and 9>8, that is, Y1≥ɑ·X1 and U1≥ɑ·X1 (that is, the first peak flow rate in this application is greater than or equal to the first value, and the first average flow rate is greater than or equal to the first value), then the electronic device can determine N3=N1+6 (that is, the first expansion warning number is increased to the second preset value in this application).

[0160] In some embodiments, combined with Figure 8,like Figure 9 As shown, in the above S702, the specific method for determining the fourth capacity expansion warning number based on the second load information of the electronic device includes:

[0161] S901, The electronic device determines the second value as the product of the second maximum bandwidth and the preset coefficient.

[0162] Specifically, the second load information includes a second maximum bandwidth. The second maximum bandwidth can represent the load capacity of the second access server. The electronic device determines the second value by multiplying the second maximum bandwidth by a preset coefficient, and this second value can be used to represent the load capacity of the second access server.

[0163] Based on the above example, assuming that the maximum bandwidth of BAS-B is X2 = 10 and the preset coefficient α = 0.8, the electronic device determines α·X2 = 8 (i.e., the second value in this application).

[0164] S902. When the second peak flow rate is greater than or equal to the second value, the electronic device increases the second capacity expansion warning number by a third preset value to obtain a fourth capacity expansion warning number.

[0165] Specifically, since the second value can represent the load capacity of the second access server, the electronic device can determine whether the load of the second access server exceeds its load capacity based on the second value and the magnitude of the second peak traffic. If the second peak traffic is greater than or equal to the second value, the electronic device can determine that the load of the second access server exceeds its load capacity. Therefore, the electronic device can determine that the communication network to which the target OLT belongs may need capacity expansion, and thus increase the second capacity expansion warning count by a third preset value to obtain a fourth capacity expansion warning count.

[0166] Based on the above example, assuming that the peak traffic of BAS-B is Y2 = 10 (i.e., the second peak traffic in this application), the second expansion warning number is N2 = 0, the maximum bandwidth is X2 = 10, and the preset coefficient α = 0.8, then the electronic device can determine α·X2 = 8.

[0167] It should be understood that 10>8, that is, Y2≥ɑ·X2 (that is, the second peak flow rate in this application is greater than or equal to the second value), then the electronic device can determine N4=N2+1 (that is, the second expansion warning number is increased to the third preset value in this application).

[0168] Optionally, the second preset value can be the same as the first preset value or it can be a different value. This application embodiment does not limit this.

[0169] S903. When the second peak flow rate is greater than or equal to the second value and the second average flow rate is greater than or equal to the second value, the electronic device increases the second capacity expansion warning number by a fourth preset value to obtain the fourth capacity expansion warning number.

[0170] When the second peak traffic is greater than or equal to the second value and the second average traffic is greater than or equal to the second value, it indicates that the communication network to which the target OLT belongs urgently needs to be expanded. Therefore, the electronic device can increase the second expansion warning number to a larger fourth preset value, that is, the fourth preset value should be greater than the third preset value.

[0171] Based on the above example, assuming Y2 = 10, U2 = 9, the second expansion warning number is N2 = 0, X2 = 10, and the preset coefficient α = 0.8, then the electronic device can determine α·X2 = 8.

[0172] It should be understood that 10>8 and 9>8, that is, Y1≥ɑ·X2 and U2≥ɑ·X2 (that is, the second peak flow rate in this application is greater than or equal to the second value, and the second average flow rate is greater than or equal to the second value), then the electronic device can determine N4=N2+6 (that is, the second expansion warning number is increased to the fourth preset value in this application).

[0173] Optionally, the fourth preset value can be the same as the third preset value or a different value; this application embodiment does not limit this.

[0174] In some embodiments, the electronic device can pre-determine multiple access servers connected to the target OLT, i.e., determine the topological relationship between the target OLT and the multiple access servers. In this case, combined with Figure 9 ,like Figure 10 As shown, before the electronic device obtains the first load information and the second load information, the load balancing method further includes:

[0175] S1001, Electronic devices acquire service link information of each OLT among multiple OLTs.

[0176] Among them, multiple OLTs include the target OLT.

[0177] In one feasible approach, electronic devices can determine the service link information of each OLT by using the online record information of user devices.

[0178] Optionally, the business link information for each OLT includes: interface information and interface status.

[0179] The interface information may include: the name of each OLT, the name of the BAS connected to each OLT, the connection method between the BAS and each OLT, the BAS interface connected to each OLT, and the maximum bandwidth between each OLT and the connected BAS.

[0180] Interface status can include: peak traffic, average traffic, and latency parameters.

[0181] For example, Table 1 shows the service link information of each OLT obtained by the electronic device.

[0182] Table 1

[0183]

[0184]

[0185] In this context, BAS interface 1 / 2 / 1 represents the first item in the first row of the first cabinet, BAS interface 1 / 1 / 1 represents the first item in the first row of the first cabinet, BAS interface 1 / 2 / 3 represents the third item in the second row of the first cabinet, and BAS interface 1 / 1 / 2 represents the second item in the first row of the first cabinet.

[0186] S1002. The electronic equipment uses a clustering algorithm to cluster multiple service link information that corresponds one-to-one with multiple OLTs in order to determine multiple access servers connected to each OLT.

[0187] Specifically, after obtaining the service link information of each OLT in multiple OLTs, since the service link information of each OLT includes the connection relationship between each OLT and the access server, the electronic device can cluster the multiple service link information corresponding to multiple OLTs one by one based on the clustering algorithm to determine the multiple access servers connected to each OLT.

[0188] Based on Table 1 above, the electronic equipment clusters the service link information of the OLT in room A and the OLT in room B to obtain the access servers connected to the OLT in room A as GDSZ-LTDS and GDSZ-TZDS, and the access servers connected to the OLT in room B as GDSZ-XNRF and GDSZ-LDDS.

[0189] In some embodiments, when the absolute value of the difference between the first ratio and the second ratio is less than a preset threshold, it indicates that the load of the first access server and the load of the second access server are the same, that is, the first load information and the second load information meet the load balancing condition. In this case, the electronic device can perform the adjustment operation corresponding to the first load information and the second load information meeting the load balancing condition. Figure 10 ,like Figure 11 As shown, this load balancing method also includes:

[0190] S1101. When the first load information and the second load information meet the load balancing conditions, the electronic device adjusts the latency parameter of the first access server and the latency parameter of the second access server to the same value.

[0191] Specifically, when the first load information and the second load information meet the load balancing condition, the electronic device determines that the load of the first access server and the load of the second access server are balanced. Therefore, the electronic device can adjust the latency parameter of the first access server and the latency parameter of the second access server to the same value.

[0192] Based on the above example, assuming U1 = 5, X1 = 10; U2 = 1, X2 = 2, and the preset threshold is 20%, the electronic device can determine the first ratio. Second ratio That is, the electronic device can determine the absolute value of the difference between the first ratio and the second ratio.

[0193] It should be understood that 0 is less than 20%, therefore, the electronic device makes Z1 = Z2 = the same value (that is, in this application, the delay parameters of the first access server and the second access server are adjusted to the same value).

[0194] In some embodiments, the above description mainly focuses on the various steps of the load balancing method provided in this application.
