[0035] Embodiment 1

[0036] Figure 1 A flow chart of a cross-domain communication network intelligent service rate mapping and switching method is provided for the first embodiment of the present invention. This embodiment can be applied to the case of determining the target link rate corresponding to the target communication service at the next moment. The method can be performed by a cross-domain communication network intelligent service rate mapping and switching device. The cross-domain communication network intelligent service rate mapping and switching device can be implemented in the form of hardware and / or software. The cross-domain communication network intelligent service rate mapping and switching device can be configured in an electronic device. Figure 1 As shown, the method includes:

[0037] S110: Acquire current link information and target service information corresponding to the target communication service to be detected.

[0038] Among them, the current link information includes: the current link type and the current link state. The target communication service may refer to the communication task that needs to be completed. The target communication service may include intra-domain communication services and cross-domain communication services. For example, in the cross-domain communication application scenario, the communication nodes may be divided into air nodes, surface nodes and underwater nodes, and the communications within and between different domains involve three major types of links, namely radio links, optical communication links and hydroacoustic communication links. For example, radio may be used between air nodes and air nodes to form a radio link. Radio may be used between surface nodes and surface nodes to form a radio link. Hydroacoustic communication may be used between underwater nodes and underwater nodes to form a hydroacoustic communication link. Optical communication may be used between air nodes and underwater nodes to form an optical communication link. Radio may be used between air nodes and surface nodes to form a radio link. Hydroacoustic communication may be used between surface nodes and underwater nodes to form a hydroacoustic communication link. The current link information may refer to the information of the link at the current moment of the communication of the target communication service. The current link type may refer to the link at the current moment, that is, the link type composed of the two communication nodes corresponding to the current link. The current link state may refer to the state information of the current link. For example, the current link state may include but is not limited to bandwidth utilization. The target service information may refer to the inherent attribute information of the target communication service. For example, the target service information may include but is not limited to the service type and service level corresponding to the target communication service.

[0039] Specifically, during the communication process of the target communication service, the current link information and the target service information corresponding to the target communication service to be detected as to whether the link rate needs to be switched can be obtained in real time or periodically.

[0040] S120: Input the current link type and target service information into the target rate decision tree for node decision, and obtain the target rate information of the target communication service in the current link.

[0041] The target rate decision tree is constructed based on the mapping relationship between each service information and rate information under each type of link. Decision trees are generally generated from top to bottom. Each decision or event (i.e., natural state) may lead to two or more events, resulting in different results. Drawing such decision branches into a graph is very similar to the branches of a tree. The target rate information may refer to the adjustable information corresponding to the communication rate (link rate) of the target communication service in the current link.

[0042] Specifically, after the current link type and target service information are input into the decision node of the target rate decision tree, the current link type is first determined to enter the next state node corresponding to the decision branch, and then the service type corresponding to the target communication service is determined to enter the next state node corresponding to the decision branch, and then the service level corresponding to the target communication service is determined to reach the result node of the corresponding branch, thereby using the target rate decision tree to complete the mapping of communication service to rate information, and obtain the target rate information of the target communication service in the current link, thereby improving the accuracy and efficiency of service rate mapping and reducing resource waste.

[0043] It should be noted that in the embodiment of the present invention, in addition to using the decision tree model, a machine learning algorithm (such as a neural network, a random forest, etc.) can also be used to construct a mapping relationship between communication services and rate information to improve the accuracy and flexibility of the mapping.

[0044] On the basis of the above technical solution, the target service information includes: target service type and target service level; the target rate information includes: target rate range and basic link rate.

[0045] The basic link rate is within the target rate interval. The target service type may correspond to the target rate interval. The target service level may correspond to the basic link rate.

[0046] On the basis of the above technical solution, "inputting the current link type and target service information into the target rate decision tree for node decision, and obtaining the target rate information of the target communication service in the current link" may include: inputting the current link type and target service information into the target rate decision tree; in the target rate decision tree, determining the first state node in the first decision branch based on the current link type, and determining the second state node in the second decision branch under the first state node based on the target service type, and determining the result node in the third decision branch under the second state node based on the target service level, and determining the target rate information of the target communication service in the current link based on the result node.

[0047] Among them, the first decision branch may refer to the first-level decision branch or the first-layer decision branch in the target rate decision tree. For example, the first decision branch may be but is not limited to all decision branches in the first layer in the target rate decision tree. In the first decision branch, select the branch with the same link type as the current link type and continue to move forward to the end of the branch to obtain a first state node. A plurality of decision branches, namely, a second decision branch, may be separated out after the first state node. The second decision branch may refer to a decision branch located in the second layer of the target rate decision tree. In the second decision branch, select the branch with the same target service type and continue to move forward to the end of the branch to obtain a second state node. A plurality of decision branches, namely, a third decision branch, may be separated out after the second state node. In the third decision branch, select the branch with the same target service level and continue to move forward to the end of the branch to obtain a result node. The result node contains target rate information corresponding to the target service type and the target service level under the current link type in advance.

[0048] Exemplarily, if it is determined that the target rate interval of the target communication service is (10, 110), and there are 4 service levels of the target communication service, then the basic link rate of each service level is the value after (10, 110) is equally divided, for example, the basic link rates of the 4 service levels of the target communication service are 30, 50, 70 and 90 respectively. If the target service level is the service level of the second priority, the basic link rate corresponding to the target service level is 70. Among them, the target rate interval corresponding to each service level of the target communication service is the same. Thus, by constructing a decision tree model, an accurate mapping of the input service type, link type and service level to service information and rate information is achieved, and then a refined adjustment strategy that comprehensively considers the service type, link characteristics (link type) and service priority (service level) is made, so that in a complex network environment, service requirements and link status can be accurately matched to avoid waste of resources and substandard service quality.

[0049] Exemplarily, the process of constructing the target rate decision tree includes: obtaining rate information of various service types of various links based on prior knowledge or historical communication data, and constructing the decision tree based on this. During the construction process, the construction of the decision tree is further completed according to the mapping relationship between the link type, service type, service level and rate information.

[0050] S130: Determine a current adjustment factor corresponding to the target communication service based on the current link status and a preset link status threshold.

[0051] The current adjustment factor may be used to adjust the link rate and may represent the adjustment range of the link rate.

[0052] Specifically, whether the link rate needs to be adjusted is determined based on the current link state and the preset link state threshold. If necessary, a current adjustment factor corresponding to the target communication service is determined based on the difference between the current link state and the preset link state threshold.

[0053] S140: Perform rate switching based on the current adjustment factor and the target rate information to determine a target link rate corresponding to the target communication service at the next moment.

[0054] Specifically, the current adjustment factor is added to one to obtain an addition result, and the addition result is multiplied by the basic link rate in the target rate information to obtain the target link rate corresponding to the target communication service at the next moment.

[0055] The technical solution of the embodiment of the present invention is to obtain the current link information and target service information corresponding to the target communication service to be detected; the current link information includes: the current link type and the current link state; the current link type and the target service information are input into the target rate decision tree for node decision, and the target rate information of the target communication service in the current link is obtained; the target rate decision tree is constructed based on the mapping relationship between each service information and the rate information under each type of link; based on the current link state and the preset link state threshold, the current adjustment factor corresponding to the target communication service is determined; based on the current adjustment factor and the target rate information, the rate is switched, so that the target link rate corresponding to the target communication service at the next moment can be accurately and conveniently determined, thereby realizing accurate rate switching, avoiding resource waste and substandard service quality.

[0056] It should be noted that the embodiments of the present invention can be designed specifically for the characteristics of cross-domain communication networks, realizing intelligent service rate mapping and switching under multiple communication modes such as radio, hydroacoustic, and optical communications in various communication environments in the air, on the surface, and underwater, and providing strong support for the efficient operation of cross-domain communication networks.

[0057] Embodiment 2

[0058] Figure 2 This is a flowchart of a cross-domain communication network intelligent service rate mapping and switching method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment describes in detail the process of determining the current adjustment factor corresponding to the target communication service. The explanations of the terms that are the same or corresponding to the above embodiments are not repeated here. Figure 2 As shown, the method includes:

[0059] S210: Acquire current link information and target service information corresponding to the target communication service to be detected.

[0060] The current link information includes: the current link type and the current link status.

[0061] S220: Input the current link type and target service information into the target rate decision tree for node decision, and obtain the target rate information of the target communication service in the current link.

[0062] The target rate decision tree is constructed based on the mapping relationship between each type of service information and rate information under each type of link.

[0063] S230: If the current link state is greater than a preset link state maximum threshold, determine a current adjustment factor corresponding to the target communication service based on a difference between the current link state and the preset link state maximum threshold.

[0064] The preset link status threshold includes: a preset link status maximum threshold and a preset link status minimum threshold; the preset link status includes: at least one of bandwidth utilization, delay and packet loss rate.

[0065] Specifically, if the current link state is greater than the preset link state maximum threshold, the difference between the current link state and the preset link state maximum threshold is determined, and the difference is normalized to obtain the current adjustment factor corresponding to the target communication service. In this case, the current adjustment factor is a positive value.

[0066] Exemplarily, before determining the current adjustment factor corresponding to the target communication service, the method also includes: obtaining a preset link state maximum threshold and a preset link state stability interval corresponding to the link state of each link, and determining a preset link state minimum threshold corresponding to the link state of each link based on the preset link state maximum threshold and the preset link state stability interval.

[0067] Specifically, the maximum bandwidth utilization threshold, bandwidth utilization stability interval, delay maximum threshold, delay stability interval, packet loss rate maximum threshold and packet loss rate stability interval of each link are obtained. Based on the maximum bandwidth utilization threshold and bandwidth utilization stability interval of each link, the minimum bandwidth utilization threshold of each link is determined. Based on the maximum delay threshold and delay stability interval of each link, the minimum delay threshold of each link is determined. Based on the maximum packet loss rate threshold and packet loss rate stability interval of each link, the minimum packet loss rate threshold of each link is determined. For example, if the maximum bandwidth utilization threshold is 90 and the bandwidth utilization stability interval is 40, the minimum bandwidth utilization threshold is 50.

[0068] S240: If the current link state is less than a preset minimum link state threshold, determine a current adjustment factor corresponding to the target communication service based on a difference between the current link state and the preset minimum link state threshold.

[0069] Specifically, if the current link state is less than the preset link state minimum threshold, the rate adjustment method is determined based on the target service level and the preset service level threshold, and the current adjustment factor corresponding to the target communication service is determined based on the difference between the current link state and the preset link state minimum threshold and the rate adjustment method.

[0070] Exemplarily, if the target service level is greater than or equal to the preset service level threshold, indicating that the basic link rate is not reduced, the current adjustment factor corresponding to the target communication service is determined to be zero, thereby ensuring the transmission quality of the key communication service. If the target service level is less than the preset service level threshold, the difference between the current link state and the preset link state minimum threshold is normalized to obtain the current adjustment factor corresponding to the target communication service. In this case, the current adjustment factor is a negative value.

[0071] S250: If the current link state is less than or equal to a preset link state maximum threshold, and the current link state is greater than or equal to a preset link state minimum threshold, then the current adjustment factor corresponding to the target communication service is determined to be zero.

[0072] Specifically, if the current link state is less than or equal to the preset link state maximum threshold, and the current link state is greater than or equal to the preset link state minimum threshold, indicating that no link rate adjustment is required, the current adjustment factor corresponding to the target communication service is determined to be zero, so that the target link rate corresponding to the target communication service at the next moment is the basic link rate.

[0073] Exemplarily, the preset link state includes bandwidth utilization, delay and packet loss rate. If the current bandwidth utilization in the current link is greater than the maximum bandwidth utilization threshold, the difference between the current bandwidth utilization and the maximum bandwidth utilization threshold is normalized to obtain the first adjustment factor corresponding to the target communication service; if the current delay in the current link is less than or equal to the maximum delay threshold, and greater than or equal to the minimum delay threshold, the second adjustment factor corresponding to the target communication service is determined to be zero. If the current packet loss rate in the current link is less than the minimum packet loss rate threshold, and the target service level is less than the preset service level threshold, the difference between the current packet loss rate and the minimum packet loss rate threshold is normalized to obtain the third adjustment factor corresponding to the target communication service. Based on the tolerance of the target communication service to bandwidth utilization, delay and packet loss rate, the first weight corresponding to the bandwidth utilization, the second weight corresponding to the delay and the third weight corresponding to the packet loss rate are obtained. For example, if the target communication service has strict requirements on the packet loss rate, the third weight corresponding to the packet loss rate is greater than the first weight and greater than the second weight. The multiplication result of the first adjustment factor and the first weight, the multiplication result of the second adjustment factor and the second weight, and the multiplication result of the third adjustment factor and the third weight are added to obtain a current adjustment factor corresponding to the target communication service.

[0074] S260: Perform rate switching based on the current adjustment factor and the target rate information to determine a target link rate corresponding to the target communication service at the next moment.

[0075] On the basis of the above technical solution, "switching the rate based on the current adjustment factor and the target rate information to determine the target link rate corresponding to the target communication service at the next moment" may include: adjusting the basic link rate in the target rate information based on the current adjustment factor to obtain the link rate to be selected; performing rate detection on the link rate to be selected based on the target rate range in the target rate information to determine the target link rate corresponding to the target communication service at the next moment.

[0076] The link rate to be selected may refer to a preliminarily determined link rate to be detected.

[0077] Specifically, the current adjustment factor is added to one to obtain the addition result, and the addition result is multiplied by the basic link rate to obtain the link rate to be selected. If the link rate to be selected is within the target rate interval, the link rate to be selected is determined as the target link rate corresponding to the target communication service at the next moment. If the link rate to be selected is outside the target rate interval, the interval boundary value of the target rate interval closest to the link rate to be selected is determined as the target link rate corresponding to the target communication service at the next moment. Thus, an intelligent algorithm is introduced to realize real-time perception of the network environment and business needs, and make more reasonable business rate switching decisions, that is, it can quickly respond to changes in the network environment and business needs, and ensure timely adjustment of the business rate. At the same time, the adaptive ability of the system is enhanced to cope with complex and changing network environments.

[0078] The technical solution of the embodiment of the present invention is as follows: if the current link state is greater than the preset link state maximum threshold, then the current adjustment factor corresponding to the target communication service is determined based on the difference between the current link state and the preset link state maximum threshold; if the current link state is less than the preset link state minimum threshold, then the current adjustment factor corresponding to the target communication service is determined based on the difference between the current link state and the preset link state minimum threshold; if the current link state is less than or equal to the preset link state maximum threshold, and the current link state is greater than or equal to the preset link state minimum threshold, then the current adjustment factor corresponding to the target communication service is determined to be zero. Thus, based on the real-time current link state and the preset link state threshold, the target link rate is dynamically adjusted to ensure efficient use of network resources and flexible adaptation to business needs.

[0079] The following is an embodiment of a cross-domain communication network intelligent service rate mapping and switching device provided in an embodiment of the present invention. The device and the cross-domain communication network intelligent service rate mapping and switching method of the above-mentioned embodiments belong to the same inventive concept.
