The objectives and other advantages of the present application may be realized and attained by the structure particularly pointed out in the specification, claims and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The drawings described herein are used to provide a further understanding of the present application and form a part of the present application. The schematic embodiments and descriptions thereof of the present application are used to explain the present application and do not constitute an improper limitation to the present application.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] For the convenience of clearly describing the technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and effects. For example, the first threshold and the second threshold are only used to distinguish different thresholds and do not limit their sequence. Those skilled in the art can understand that terms such as "first" and "second" do not limit the quantity and execution order, and terms such as "first" and "second" do not necessarily mean different.

[0020] It should be noted that in the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner.

[0021] In this application, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can mean: a, b, c, the combination of a and b, the combination of a and c, the combination of b and c, or the combination of a, b and c, where a, b, c can be single or multiple.

[0022] In the optical fiber system, due to the lack of efficient monitoring means to collect and analyze the parameters of each frequency band in real time, and the resource utilization rate is often unable to be accurately quantified, some frequency bands may be in an overloaded state for a long time, while others are idle. This imbalance shows the blindness of the current optical resource allocation, which leads to the inefficiency of network operation. At the same time, the traditional static management method can no longer meet the needs of complex network scenarios, and the optical fiber system still has the problem of degraded service quality. Therefore, how to intelligently adjust the optical resource allocation based on the dynamically changing communication environment has become a difficult problem that needs to be solved urgently.

[0023] In order to solve the problems existing in the prior art, the embodiment of the present application provides a method for real-time management and status monitoring of optical splitting resources, which is used to improve the utilization efficiency of optical splitting resources while meeting user needs, such as Figure 1 As shown: Figure 1 A method for real-time management and status monitoring of optical resources provided in an embodiment of the present application includes: S101: acquiring an optical resource status indicator of each channel in the optical fiber system at a preset time interval, wherein the optical resource status indicator includes an indicator affecting the use of the optical resource of the channel; In an optional embodiment, the preset time interval can be set by relevant personnel themselves and changed at any time, or it can be a fixed value. The optical fiber system can be applied to scenarios such as constructing a local optical fiber network, a national optical fiber network, and an undersea optical fiber network. Optical fiber communication is a communication method that uses light waves as information carriers and optical fibers as transmission media. Binary optical pulses "0" and "1" are transmitted in the optical fiber. The channel in this embodiment can be any one or a combination of multiple of the three structures: point-to-point, arbitration loop, and switching fabric. The optical division resource status indicators in this embodiment can be any one or more of bit error rate, channel capacity, delay, signal-to-noise ratio, bandwidth efficiency, and transmission rate, or other indicators that affect the use of optical division resources in the channel of the optical fiber system. This embodiment does not limit this. Among them, optical division resources are also called optical resources, optical fiber resources, etc., and are the same concept in this embodiment.

[0024] S102: Determine the optical division resource usage status of each channel in the optical fiber system according to the optical division resource status indicator, where the optical division resource usage status includes an overload status and an underload status; In one embodiment, the overload status means that the amount of data that needs to be transmitted by the channel in the optical fiber system exceeds the maximum amount of data that the channel can bear according to the current transmission method, and the underload status means that the amount of data that needs to be transmitted by the channel in the optical fiber system is less than the maximum amount of data that the channel can bear according to the current transmission method. Determine the usage status of each channel through the obtained optical division resource indicator data in real time.

[0025] S103: Reallocate the optical division resources of the optical fiber system according to the optical division resource usage status of each channel to improve the usage efficiency of the optical division resources of the optical fiber system; According to the optical division resource usage status of each channel obtained in real time in the embodiment of the present invention, that is, whether the channel transmission information is in an overload or underload situation, the optical division resources in the optical fiber system are reallocated, realizing flexible and dynamic resource adjustment, realizing customized management according to different communication scenarios, and improving the resource usage efficiency of the optical division resources in the optical fiber system.

[0026] S104: Obtain the optical division resource status indicator after reallocation and the predicted value of the optical division resource usage in the next time period, and determine whether the optical fiber system after the optical division resource reallocation meets the optical division resource usage requirements according to the optical division resource status indicator after reallocation and the predicted value of the optical division resource usage; In the embodiments of the present invention, since the reallocated optical splitting resources meet the optical splitting resource requirements at the current moment, they may not necessarily meet the optical splitting resource requirements at the next moment. For example, at 17:59:30, the main users of the optical fiber system are at work and have a relatively high demand for optical splitting resources. When the next moment is 18:00, the main users of the optical fiber system get off work and the demand for optical fiber resources drops sharply. At this time, if only the optical splitting resource usage status at the current moment is used to adjust the optical fiber resources at the next moment, there will inevitably be a large deviation. The embodiments of the present invention refer to both the demand information at the current moment and the prediction information at the next moment, avoiding the waste of optical splitting resources while meeting the demand of the users of the optical fiber system for optical splitting resources, and taking into account the reliability and efficiency of the optical fiber system.

[0027] S105: If not satisfied, reallocate the optical splitting resources of the optical fiber system again to enable the optical fiber system to meet the optical splitting resource usage requirements.

[0028] In the embodiments of the present application, by obtaining the optical splitting resource status indicators of each channel in the optical fiber system at preset time intervals, where the optical splitting resource status indicators include the indicators affecting the optical splitting resource usage of the channel; determining the optical splitting resource usage status of each channel in the optical fiber system according to the optical splitting resource status indicators, where the optical splitting resource usage status includes the overloaded status and the underloaded status; reallocating the optical splitting resources of the optical fiber system according to the optical splitting resource usage status of each channel to improve the optical splitting resource usage efficiency of the optical fiber system; obtaining the optical splitting resource status indicators after reallocation and the predicted value of the optical splitting resource usage in the next time period, and judging whether the optical fiber system after the optical splitting resource reallocation meets the optical splitting resource usage requirements according to the optical splitting resource status indicators after reallocation and the predicted value of the optical splitting resource usage; if not satisfied, reallocate the optical splitting resources of the optical fiber system again to enable the optical fiber system to meet the optical splitting resource usage requirements. The real-time dynamic adjustment and control of the optical splitting resources are realized, and then the balance between the user requirements and the usage efficiency is realized, solving the technical problems of poor flexibility and poor dynamic adjustment ability in the management of the optical splitting resources in the optical fiber system, and achieving the technical effect of improving the optical splitting resource usage efficiency while meeting the user requirements.

[0029] Further, the optical splitting resource status indicators include the channel utilization rate and the average delay; In step S102, determining the optical splitting resource usage status of each channel in the optical fiber system according to the optical splitting resource status indicators includes: S1021: Calculate the first optical splitting resource status index according to the channel utilization rate and the average delay according to the first calculation formula, where the first optical splitting resource status index includes the index for evaluating the optical splitting resource usage of the channel, and the first calculation formula satisfies: + , is the first optical splitter resource status index, is the channel utilization rate, D is the average delay, is the maximum delay allowed by the channel, is the first correlation parameter, 0 < < 1; S1022: Determine the optical splitter resource usage status of each channel in the optical fiber system according to the relationship between the first optical splitter resource status index and the first threshold, where the first threshold includes the first optical splitter resource status index corresponding to the full-load state of the optical splitter resource usage status.

[0030] In the embodiments of the present invention, the channel utilization rate can be the transmission time of data in the channel divided by the sum of the transmission time and the idle time. The average delay can be the average value of the duration from request to response. Software can be installed in the optical fiber system to detect the channel utilization rate and the average delay. From the perspective of the time domain, this embodiment calculates the optical splitter resource status index to quantify the optical splitter resource usage status of each channel in the optical fiber system, realizing precise control of the optical splitter resources in the optical fiber system.

[0031] Further, the optical splitter resource status index includes the bandwidth utilization rate and the signal-to-noise ratio; In step S102, according to the optical splitter resource status index, determining the optical splitter resource usage status of each channel in the optical fiber system includes: S1023: Calculate the second optical splitter resource status index according to the bandwidth utilization rate and the signal-to-noise ratio according to the second calculation formula, where the second optical splitter resource status index includes an index for evaluating the optical splitter resource usage of the channel, and the second calculation formula satisfies: (1 + S), is the second optical splitter resource status index, is the bandwidth utilization rate, S is the signal-to-noise ratio; S1024: Determine the optical splitter resource usage status of each channel in the optical fiber system according to the relationship between the second optical splitter resource status index and the second threshold, where the second threshold includes the second optical splitter resource status index corresponding to the full-load state of the optical splitter resource usage status.

[0032] In the embodiments of the present invention, the bandwidth utilization rate can refer to the transmission rate per unit bandwidth, and the signal-to-noise ratio can refer to the ratio of the signal power to the noise power. Software can be installed in the optical fiber system to detect the bandwidth utilization rate and the signal-to-noise ratio, or relevant instruments, such as a spectrum analyzer, can be connected to the optical fiber system to detect the bandwidth utilization rate and the signal-to-noise ratio. From the perspective of the frequency domain, this embodiment calculates the optical splitter resource status index to quantify the optical splitter resource usage status of each channel in the optical fiber system, realizing precise control of the optical splitter resources in the optical fiber system.

[0033] Further, in step S103, according to the optical splitting resource usage status of each channel, optical splitting resource reallocation is performed on the optical fiber system, including: S1031: When the optical splitting resource usage status of a channel is in an overloaded state, adjust the communication strategies of the channel and the adjacent channels in the next time period to improve the optical splitting resource usage efficiency of the optical fiber system, where the next time period includes a time period with a preset time length adjacent to the current time period; S1032: When the optical splitting resource usage status of a channel is in an underloaded state, increase the number of optical fiber nodes accessed in the channel in the next time period.

[0034] Further, in step S1031, adjusting the communication strategies of the channel and the adjacent channels in the next time period includes: S10311: When the first optical splitting resource status index is lower than the first threshold and greater than or equal to the third threshold, or when the second optical splitting resource status index is lower than the second threshold and greater than or equal to the fourth threshold, for the channel, in the next time period, use time-division multiplexing and frequency-division multiplexing simultaneously for data transmission; S10312: When the first optical splitting resource status index is lower than the third threshold, or when the second optical splitting resource status index is lower than the fourth threshold, for the channel, in the next time period, use orthogonal frequency-division multiplexing, code-division multiplexing, and space-division multiplexing simultaneously for data transmission.

[0035] The embodiments of the present invention only adjust the communication strategies of the channels in the optical fiber system, and do not limit how to perform time-division multiplexing, frequency-division multiplexing, orthogonal frequency-division multiplexing, code-division multiplexing, and space-division multiplexing specifically. It should be noted that due to the limitations of different optical fiber hardware in implementing space-division multiplexing, if the optical fiber device does not support space-division multiplexing, such as when there is no multi-core optical fiber in the channel, when the first optical splitting resource status index is lower than the third threshold, or when the second optical splitting resource status index is lower than the fourth threshold, only orthogonal frequency-division multiplexing and code-division multiplexing are used.

[0036] Further, in step S104, obtaining the predicted value of the optical splitting resource usage in the next time period includes: S1041: Input the time value corresponding to the next time period into the neural network model to obtain the predicted value of the optical splitting resource usage output by the neural network, where the neural network model is trained according to historical data; S104: According to the reallocated optical splitting resource status index and the predicted value of the optical splitting resource usage, determine whether the optical fiber system after optical splitting resource reallocation meets the optical splitting resource usage requirements, including: S1042: Obtain the optical splitting resource status index corresponding to the predicted value of the optical splitting resource usage, and calculate the difference between the reallocated optical splitting resource status index and the optical splitting resource status index corresponding to the predicted value of the optical splitting resource usage; S1043: Determine whether the optical fiber system after optical splitter resource reallocation meets the optical splitter resource usage requirements according to the relationship between the difference and the preset threshold.

[0037] In an alternative embodiment, the preset threshold can be set by relevant personnel. If the difference is less than the preset threshold, it can be determined that the optical fiber system after optical splitter resource reallocation meets the optical splitter resource usage requirements. If the difference is greater than the preset threshold, it can be determined that the optical fiber system after optical splitter resource reallocation does not meet the optical splitter resource usage requirements.

[0038] Further, S105: Re-perform optical splitter resource reallocation on the optical fiber system, including: S1051: Calculate the optical splitter resource reallocation coefficient according to the third calculation formula, where the third calculation formula satisfies: , C is the optical splitter resource reallocation coefficient, R is the optical splitter resource status index after reallocation, P is the optical splitter resource status index corresponding to the optical splitter resource usage prediction value, is the first weight, is the second weight, = 1; It should be noted that in this embodiment, when the optical splitter resource status index R after reallocation is a time domain index, the optical splitter resource status index P corresponding to the optical splitter resource usage prediction value is also a time domain index; when the optical splitter resource status index R after reallocation is a frequency domain index, the optical splitter resource status index P corresponding to the optical splitter resource usage prediction value is also a frequency domain index.

[0039] S1052: Reallocate the optical splitter resources for all channels in the optical fiber system according to the optical splitter resource reallocation coefficient.

[0040] Further, after step S106 of determining whether the optical fiber system after optical splitter resource reallocation meets the optical splitter resource usage requirements, it further includes: Update the preset threshold according to the relationship between the difference and the preset threshold.

[0041] In an alternative embodiment, the levels of the preset threshold can be preset, from large to small, namely level one, level two to level ten. If the difference is greater than the preset threshold, that is, when the optical fiber system after optical splitter resource reallocation does not meet the optical splitter resource usage requirements, the level of the preset threshold is adjusted to one level larger than the current level. If the difference is less than the preset threshold, that is, when the optical fiber system after optical splitter resource reallocation does not meet the optical splitter resource usage requirements, the level of the preset threshold is adjusted to one level smaller than the current level. When the level of the preset threshold is already the largest level or the smallest level, no adjustment is made. This embodiment dynamically adjusts the preset threshold, improving the self-adaptability of the optical fiber system and enabling the optical fiber system to be applicable to communication requirements in a variety of different scenarios.

[0042] Further, it further includes: S107: Generate an optical splitter resource status report graph of the optical fiber system according to the optical splitter resource status indicators of each channel in the optical fiber system at a preset time interval; S108: When a display instruction is received, display the optical splitter resource status report graph.

[0043] In one embodiment, the display content and method in the optical splitter resource status report graph can be selected by relevant personnel, and this embodiment does not limit this.

Please refer to Figure 2 , Figure 2 which is a structural diagram of a real-time management and status monitoring system for optical splitter resources provided by an embodiment of the present application.
