[0035] Example 1

[0036] Figure 1 A flowchart 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 is applicable 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: Obtain current link information and target service information corresponding to the target communication service to be detected.

[0038] The current link information includes the current link type and the current link status. The target communication service may refer to the communication task to be completed. Target communication services may include intra-domain communication services and cross-domain communication services. For example, in cross-domain communication scenarios, communication nodes may be divided into aerial nodes, surface nodes, and underwater nodes. Communications within and between different domains involve three types of links: radio links, optical links, and underwater acoustic links. For example, aerial nodes may communicate with each other using radio, forming a radio link. Surface nodes may communicate with each other using radio, forming a radio link. Underwater nodes may communicate with each other using underwater acoustic links, forming an underwater acoustic link. Aerial nodes may communicate with each other using optical links, forming an optical link. Aerial nodes may communicate with each other using radio, forming a radio link. Surface nodes may communicate with each other using underwater acoustic links, forming an underwater acoustic link. Current link information may refer to the link currently associated with the target communication service. The current link type may refer to the link currently associated with the target communication service, i.e., the link type of the two communication nodes corresponding to the current link. The current link status may refer to information about the current link status. For example, the current link status may include, but is not limited to, bandwidth utilization. The target service information may refer to 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 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 a target rate decision tree for node decision, and obtain target rate information of the target communication service in the current link.

[0041] The target rate decision tree is constructed based on the mapping between each service and rate information for each link type. Decision trees are generally generated from the top down. Each decision or event (i.e., natural state) may lead to two or more events, resulting in different outcomes. Graphically depicting these decision branches resembles the branches of a tree. The target rate information can be adjustable information corresponding to the target communication service's communication rate (link rate) on 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 judged to enter the next state node corresponding to the decision branch, and then the service type corresponding to the target communication service is judged to enter the next state node corresponding to the decision branch, and then the service level corresponding to the target communication service is judged to reach the result node of the corresponding branch, so as to complete the mapping of the communication service to the rate information using the target rate decision tree, and obtain the target rate information of the target communication service in the current link, thereby improving the accuracy and efficiency of the 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, machine learning algorithms (such as neural networks, random forests, 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 range. The target service type may correspond to the target rate range. 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 to obtain 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 can 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 can be but is not limited to all decision branches in the first layer of the target rate decision tree. In the first decision branch, select the branch with the same type as the current link and continue to move forward to the end of the branch to obtain a first state node. The first state node can be followed by multiple decision branches, namely the second decision branch. The second decision branch can refer to the decision branch located in the second layer of the target rate decision tree. In the second decision branch, select the branch with the same type as the target service and continue to move forward to the end of the branch to obtain a second state node. The second state node can be followed by multiple decision branches, namely the third decision branch. In the third decision branch, select the branch with the same level as the target service and continue to move forward to the end of the branch to obtain a result node. The result node contains the target rate information that is pre-corresponding to the target service type and target service level under the current link type.

[0048] For example, 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 obtained by equally dividing (10, 110), 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, then 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 is comprehensively considered with respect to the service type, link characteristics (link type) and service priority (service level), so that the service demand and link status can be accurately matched in a complex network environment, thus avoiding waste of resources and substandard service quality.

[0049] Exemplarily, the process of constructing a target rate decision tree includes obtaining rate information for various service types on various links based on prior knowledge or historical communication data, and constructing a decision tree based on this information. During the construction process, the decision tree is further constructed based on the mapping relationship between 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 state and a preset link state threshold.

[0051] The current adjustment factor may be used to adjust the link rate and may represent an 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 a 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 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 obtains current link information and target service information corresponding to the target communication service to be detected; the current link information includes: current link type and current link status; the current link type and target service information are input into a 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 type of service information and rate information under each type of link; based on the current link status and a preset link status threshold, the current adjustment factor corresponding to the target communication service is determined; based on the current adjustment factor and the target rate information, rate switching is performed, so that the target link rate corresponding to the target communication service at the next moment can be accurately and conveniently determined, thereby achieving 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, underwater acoustic, and optical communication 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] Example 2

[0058] Figure 2 This is a flowchart of a cross-domain communication network intelligent service rate mapping and switching method provided by the second embodiment of the present invention. Based on the above embodiment, 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 a target rate decision tree for node decision, and obtain 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 the 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 thresholds include: 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 a 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 a 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 the 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, then 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] For example, if the target service level is greater than or equal to the preset service level threshold, indicating that the basic link rate will not be reduced, the current adjustment factor corresponding to the target communication service is set to zero, thereby ensuring the transmission quality of critical communication services. 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 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.

[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] For example, a preset link state includes bandwidth utilization, delay, and packet loss rate. If the current bandwidth utilization of the current link is greater than a maximum bandwidth utilization threshold, the difference between the current bandwidth utilization and the maximum bandwidth utilization threshold is normalized to obtain a first adjustment factor corresponding to the target communication service. If the current delay of 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 of the current link is less than the minimum packet loss rate threshold, and the target service level is less than a preset service level threshold, the difference between the current packet loss rate and the minimum packet loss rate threshold is normalized to obtain a third adjustment factor corresponding to the target communication service. Based on the target communication service's tolerance for bandwidth utilization, delay, and packet loss rate, a first weight corresponding to bandwidth utilization, a second weight corresponding to delay, and a third weight corresponding to packet loss rate are obtained. For example, if the target communication service has strict requirements for packet loss rate, the third weight corresponding to packet loss rate is greater than the first weight and greater than the second weight. A multiplication result of the first adjustment factor and the first weight, a multiplication result of the second adjustment factor and the second weight, and a 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, "performing rate switching based on the current adjustment factor and 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 interval 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 an 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 achieve 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 determines the current adjustment factor corresponding to the target communication service based on the difference between the current link state and the preset link state maximum threshold if the current link state is greater than the preset link state maximum threshold; determines the current adjustment factor corresponding to the target communication service based on the difference between the current link state and the preset link state minimum threshold if the current link state is less than the preset link state minimum threshold; and determines the current adjustment factor corresponding to the target communication service to be zero 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. Thus, the target link rate is dynamically adjusted based on the real-time current link state and the preset link state threshold, ensuring efficient utilization of network resources and flexible adaptation to service needs.

[0079] The following is an embodiment of the cross-domain communication network intelligent service rate mapping and switching device provided by 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.
