[0051] To facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. For example, the first threshold and the second threshold are merely used to distinguish between different thresholds and do not limit their order. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity or execution order, and words such as "first" and "second" do not necessarily mean that they are different.

[0052] It should be noted that, in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0053] In this application, "at least one" means one or more, and "more" 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: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" 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 plural.

[0054] In optical fiber systems, due to a lack of efficient monitoring methods for real-time collection and analysis of frequency band parameters, and the inability to accurately quantify resource utilization, some frequency bands may be chronically overloaded while others remain idle. This imbalance demonstrates the blind approach to current optical resource allocation, leading to inefficient network operations. Furthermore, traditional static management methods are no longer sufficient for complex network scenarios, and optical fiber systems also suffer from degraded service quality. Therefore, intelligently adjusting optical resource allocation based on the dynamically changing communication environment has become a pressing challenge.

[0055] 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 resources, which is used to meet user needs while improving the efficiency of optical resource utilization, such as Figure 1 As shown: Figure 1 A method for real-time management and status monitoring of optical splitting resources provided in an embodiment of the present application includes:

[0056] S101: Obtaining an optical resource status indicator of each channel in an optical fiber system at a preset time interval, wherein the optical resource status indicator includes an indicator that affects the optical resource usage of the channel;

[0057] In an optional embodiment, the preset time interval can be set by relevant personnel and changed at any time, or it can be a fixed value. The fiber optic system can be used to form a local fiber optic network, a national fiber optic network, an international fiber optic network, and other scenarios. Fiber optic communication is a communication method that uses light waves as information carriers and optical fiber as a transmission medium. Binary light pulses "0" and "1" are transmitted in the optical fiber. The channel in this embodiment can be any one or more of the three structures: point-to-point, arbitration loop, and switching structure. The optical resource status indicator in this embodiment can be any one or more of the following: bit error rate, channel capacity, latency, signal-to-noise ratio, bandwidth efficiency, and transmission rate. It can also be other indicators that affect the utilization of optical resource channels in the fiber optic system, which is not limited in this embodiment. Optical resource is also referred to as optical resource, fiber resource, etc., and in this embodiment, they are the same concept.

[0058] S102: Determine the optical resource usage status of each channel in the optical fiber system according to the optical resource status indicator, wherein the optical resource usage status includes an overload state and an underload state;

[0059] In one embodiment, an overload state refers to a situation where the amount of data required to be transmitted by a channel in the optical fiber system exceeds the maximum amount of data that the channel can support under the current transmission mode. An underload state refers to a situation where the amount of data required to be transmitted by a channel in the optical fiber system is less than the maximum amount of data that the channel can support under the current transmission mode. The usage status of each channel is determined based on real-time acquired optical resource indicator data.

[0060] S103: reallocating the optical resources of the optical fiber system according to the optical resource usage status of each channel to improve the optical resource usage efficiency of the optical fiber system;

[0061] The embodiment of the present invention reallocates the optical resources in the optical fiber system according to the real-time acquired optical resource usage status of each channel, that is, whether the channel transmission information is overloaded or underloaded, thereby realizing flexible and dynamic resource adjustment, realizing customized management according to different communication scenarios, and improving the resource utilization efficiency of the optical resources in the optical fiber system.

[0062] S104: Obtaining a status indicator of the optical resource after reallocation and a predicted value of optical resource usage for the next period, and determining whether the optical fiber system after the optical resource reallocation meets the optical resource usage demand based on the status indicator of the optical resource after reallocation and the predicted value of optical resource usage;

[0063] In this embodiment of the present invention, the reallocated optical resources meet the optical resource demand at the current moment, but may not meet the optical resource demand at the next moment. For example, at 5:59:30 PM, the primary users of the optical fiber system are at work, and their demand for optical resources is high. At 6:00 PM, the primary users of the optical fiber system are off duty, and their demand for optical resources drops sharply. If the optical fiber resources at the next moment are adjusted based solely on the current optical resource usage status, there will inevitably be a significant deviation. This embodiment of the present invention simultaneously references both the current demand information and the predicted information for the next moment, thereby meeting the optical resource demand of the optical fiber system users while avoiding waste of optical resources and ensuring both the reliability and efficiency of the optical fiber system.

[0064] S105: If not, reallocate the optical resources of the optical fiber system again to enable the optical fiber system to meet the optical resource usage demand.

[0065] The embodiment of the present application obtains the optical resource status indicator of each channel in the optical fiber system at preset time intervals, wherein the optical resource status indicator includes an indicator that affects the optical resource usage of the channel; determines the optical resource usage status of each channel in the optical fiber system based on the optical resource status indicator, wherein the optical resource usage status includes an overload state and an underload state; reallocates the optical resource of the optical fiber system based on the optical resource usage status of each channel to improve the optical resource usage efficiency of the optical fiber system; obtains the optical resource status indicator after reallocation and the predicted value of optical resource usage in the next time period, and determines whether the optical fiber system after the optical resource reallocation meets the optical resource usage demand based on the optical resource status indicator after reallocation and the predicted value of optical resource usage; if not, reallocates the optical resource of the optical fiber system again to ensure that the optical fiber system meets the optical resource usage demand. This achieves real-time dynamic adjustment and control of optical resources, thereby achieving a balance between user needs and usage efficiency, solving the technical problems of poor flexibility and poor dynamic adjustment capability of optical resource management in the optical fiber system, and achieving the technical effect of meeting user needs while improving the efficiency of optical resource usage.

[0066] Furthermore, the optical resource status indicators include channel utilization and average delay;

[0067] In step S102, the optical division resource usage status of each channel in the optical fiber system is determined according to the optical division resource status indicator, including:

[0069] S1022: Determine the optical resource usage status of each channel in the optical fiber system based on the relationship between the first optical resource status index and the first threshold, wherein the first threshold includes the first optical resource status index corresponding to when the optical resource usage status is in a full load state.

[0070] In an embodiment of the present invention, the channel utilization rate may be the transmission time of data in the channel divided by the sum of the transmission time and the idle time. The average delay may be the average of the time length from request to response. Software may be installed in the optical fiber system to detect the channel utilization rate and the average delay. This embodiment calculates the optical resource status index from a time domain perspective, which is used to quantify the optical resource usage status of each channel in the optical fiber system, thereby realizing precise control of the optical resources in the optical fiber system.

[0071] Furthermore, the optical resource status indicators include bandwidth utilization and signal-to-noise ratio;

[0072] In step S102, the optical division resource usage status of each channel in the optical fiber system is determined according to the optical division resource status indicator, including:

[0073] S1023: Calculate a second optical resource status index according to the frequency band utilization and the signal-to-noise ratio and a second calculation formula, wherein the second optical resource status index includes an index for evaluating optical resource usage of a channel, and the second calculation formula satisfies: (1+S), is the second optical resource status index, is the bandwidth utilization, S is the signal-to-noise ratio;

[0074] S1024: Determine the optical resource usage status of each channel in the optical fiber system according to the relationship between the second optical resource status index and the second threshold, wherein the second threshold includes the second optical resource status index corresponding to when the optical resource usage status is in a full load state.

[0075] In an embodiment of the present invention, the frequency band utilization rate may refer to the transmission rate per unit bandwidth, and the signal-to-noise ratio may refer to the ratio of signal power to noise power. Software may be installed in the optical fiber system to detect the frequency band utilization rate and the signal-to-noise ratio, or related instruments, such as a spectrum analyzer, may be connected to the optical fiber system to detect the frequency band utilization rate and the signal-to-noise ratio. This embodiment calculates the optical resource status index from the perspective of the frequency domain, which is used to quantify the optical resource usage status of each channel in the optical fiber system, thereby realizing precise control of the optical resources in the optical fiber system.

[0076] Furthermore, in step S103, the optical fiber system is reallocated according to the optical resource usage status of each channel, including:

[0077] S1031: When the optical division resource usage state of the channel is in an overload state, adjusting the communication strategy of the channel and adjacent channels in a next time period to improve the optical division resource usage efficiency of the optical fiber system, wherein the next time period includes a time period of a next preset time length adjacent to the current time period;

[0078] S1032: When the optical resource usage status of the channel is underloaded, increase the number of access optical fiber nodes in the channel in the next time period.

[0079] Furthermore, in step S1031, the communication strategies of the channel and the channels adjacent to the channel are adjusted in the next period, including:

[0080] S10311: When the first optical division resource status index is lower than the first threshold and greater than or equal to the third threshold, or when the second optical division 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, simultaneously use time division multiplexing and frequency division multiplexing for data transmission;

[0081] S10312: When the first optical division resource status index is lower than the third threshold, or when the second optical division resource status index is lower than the fourth threshold, for the channel, in the next time period, orthogonal frequency division multiplexing, code division multiplexing and space division multiplexing are used simultaneously for data transmission.

[0082] The embodiments of the present invention only adjust the communication strategy of the channels in the optical fiber system and do not limit the specific implementation of time division multiplexing, frequency division multiplexing, orthogonal frequency division multiplexing, code division multiplexing, and space division multiplexing. It should be noted that due to the limitations of different optical fiber hardware on the implementation of space division multiplexing, if the optical fiber equipment does not support space division multiplexing, such as when the channel does not have multi-core optical fiber, when the first optical division resource status index is lower than the third threshold, or when the second optical division resource status index is lower than the fourth threshold, only orthogonal frequency division multiplexing and code division multiplexing will be used.

[0083] Furthermore, in step S104, obtaining the predicted value of optical resource usage in the next time period includes:

[0087] S1043: Determine, based on the relationship between the difference and a preset threshold, whether the optical fiber system after the optical division resource reallocation satisfies the optical division resource usage requirement.

[0088] In an optional embodiment, the preset threshold can be set by relevant personnel. If the difference is less than the preset threshold, it can be judged that the optical fiber system after the optical resource reallocation meets the optical resource usage demand. If the difference is greater than the preset threshold, it can be judged that the optical fiber system after the optical resource reallocation does not meet the optical resource usage demand.

[0089] Furthermore, S105: re-allocating optical resources of the optical fiber system, including:

[0092] S1052: Perform optical resource reallocation on all channels in the optical fiber system according to the optical resource reallocation coefficient.

[0093] Furthermore, after determining whether the optical fiber system after the optical division resource reallocation satisfies the optical division resource usage requirement in step S106, the method further includes:

[0094] The preset threshold is updated according to the relationship between the difference and the preset threshold.

[0095] In an optional embodiment, the level of the preset threshold can be pre-set, from level one, level two to level ten, from large to small. If the difference is greater than the preset threshold, that is, the optical fiber system after the optical resource reallocation does not meet the optical resource usage demand, the level of the preset threshold is adjusted to be one level larger than the current level. If the difference is less than the preset threshold, that is, the optical fiber system after the optical resource reallocation does not meet the optical resource usage demand, the level of the preset threshold is adjusted to be one level smaller than the current level. When the level of the preset threshold is already the maximum level or the minimum level, no adjustment is made. This embodiment dynamically adjusts the preset threshold, improves the adaptability of the optical fiber system, and enables the optical fiber system to adapt to the communication needs of a variety of different scenarios.
