[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0046] In one embodiment, Figure 1As shown, a bandwidth control method is provided. This embodiment uses the method applied to a speed limit center as an example. The speed limit center can be a server, and the server can be implemented as an independent server or a server cluster composed of multiple servers. In this embodiment, the method includes the following steps:

[0047] Step S110, read the speed limit domain name configuration information.

[0048] The speed-limited domain name configuration information includes configuration information required for implementing bandwidth control on the target domain name.

[0049] The target domain name may be a domain name that requires real-time bandwidth control.

[0050] The bandwidth range of the target domain name includes a pre-controlled area and a controlled area.

[0051] The bandwidth range of the target domain name also includes a normal zone with no speed limit.

[0052] Among them, the pre-control area is used to receive pre-control instructions; the controlled area is used to receive controlled instructions.

[0053] The division of the normal area, the pre-control area and the controlled area can be determined according to the threshold ratio of the pre-control area corresponding to the target domain name and the corresponding restricted bandwidth.

[0054] The bandwidth threshold can be determined according to the threshold ratio of the restricted bandwidth and the pre-control area. The area less than the bandwidth threshold is the normal area, the area between the bandwidth threshold and the restricted bandwidth is the pre-control area, and the area exceeding the restricted bandwidth is the controlled area.

[0055] For example, the configuration file will configure the threshold ratio of the pre-control area.

[0056] Assume that the limited bandwidth is 100G and the threshold ratio of the pre-control area is 80%, then the bandwidth threshold is 80G, where:

[0057] Normal area: Bandwidth range (0-80G) does not perform any processing on bandwidth.

[0058] Pre-control area: Set an upper limit for the bandwidth range (80G-100G) to control the number of requests per second. Since the upper limit has not been reached at this time, it will not have any impact on user requests. It only prevents sudden requests from causing a sharp increase in bandwidth.

[0059] Controlled area: bandwidth range (greater than 100G) At this time, the actual bandwidth has exceeded the control value and the bandwidth needs to be reduced.

[0060] In the specific implementation, Figure 2As shown, a flow chart of another bandwidth control method is provided, and the speed limit center can load the speed limit domain name file, read and parse the configuration information in the speed limit domain name file, and obtain the speed limit domain name configuration information. The speed limit domain name configuration information may include but is not limited to at least one of the speed limit type, the pre-control area threshold ratio, the speed limit gear parameter, the speed limit gear status code, and the adaptive speed limit parameter.

[0061] The speed limit domain name file is a file that stores and manages configuration information related to bandwidth speed limit.

[0062] The speed limit domain name configuration information refers to various parameters and settings required for implementing bandwidth control on the target domain name in the speed limit domain name file.

[0063] The speed limit type is used to specify the speed limit mode applicable to the target domain name, such as gear speed limit or adaptive speed limit.

[0064] The threshold ratio of the pre-control area is used to set the usage ratio of the bandwidth in the pre-control area to ensure that the bandwidth control strategy can be triggered when the traffic reaches a certain threshold.

[0065] The speed limit gear parameter is used to describe different speed limit gear settings of the bandwidth speed limit. For example, different speed limit gears correspond to different speed limit values ​​and processing rules.

[0066] The speed limit gear status code is used to indicate the status of the current speed limit gear, and is usually used to characterize the level of the current bandwidth restriction.

[0067] The adaptive speed limit parameters may include rules and conditions related to dynamically adjusting the speed limit to adapt to real-time traffic changes, and are used to specify how to adjust the bandwidth limit according to the real-time network status to achieve dynamic speed limit.

[0068] Step S120: query the current operation index of the target domain name on the corresponding edge host according to the speed limit domain name configuration information.

[0069] The operation indicators include at least one of the upstream bandwidth, downstream bandwidth, query rate data per second (QPS (Queries Per Second)) and current transmission speed corresponding to the target domain name.

[0070] In a specific implementation, the speed limit center can query the current operating indicators of the target domain name on the corresponding edge host in the monitoring center according to the speed limit domain name configuration information.

[0071] In some embodiments, the configuration information includes a threshold ratio and a speed limit gear parameter of the pre-control zone. According to the speed limit domain name configuration information, the target domain name's current operating indicators on the corresponding edge host are queried, including: determining the bandwidth threshold of the pre-control zone at the lowest speed limit gear according to the threshold ratio and the speed limit gear parameter of the pre-control zone; periodically querying the total bandwidth corresponding to the target domain name, and when the total bandwidth corresponding to the target domain name is greater than the bandwidth threshold of the pre-control zone at the lowest speed limit gear, querying the target domain name's current operating indicators on the corresponding edge host.

[0072] In the specific implementation, the speed limit center queries the current running indicators of the target domain name on the corresponding edge host according to the speed limit domain name configuration information, such as Figure 2 As shown, the speed limit center can determine the bandwidth threshold of the pre-control area at the lowest speed limit gear according to the threshold ratio of the pre-control area and the speed limit gear parameters, and periodically query the total bandwidth (including uplink bandwidth and downlink bandwidth) and speed and other indicators corresponding to the target domain name to the monitoring center according to the target domain name. If the total bandwidth corresponding to the target domain name is less than the bandwidth threshold of the pre-control area at the lowest speed limit gear, the bandwidth control requirement is not met and there is no need to implement the bandwidth control strategy.

[0073] If the total bandwidth corresponding to the target domain name is greater than the bandwidth threshold of the pre-control area at the lowest speed limit gear at this time, the speed limit requirement is met and the bandwidth control strategy needs to be implemented; then, the speed limit center continues to query the monitoring center for the current operating indicators of the target domain name on the corresponding edge host, and returns the upstream bandwidth, downstream bandwidth, QPS data and current speed indicators at the domain name and IP granularity, and stores its data indicators according to the domain name and IP granularity.

[0074] Step S130: Generate target speed limit information according to the bandwidth control strategy and the current operation index, and send the target speed limit information to the edge host.

[0075] The bandwidth control strategy includes at least one of a gear speed limit strategy or an adaptive speed limit strategy.

[0076] The target speed limit information includes pre-control speed limit information for the pre-control area or controlled speed limit information for the controlled area.

[0077] In a specific implementation, the speed limit center can generate target speed limit information according to the bandwidth control strategy and the current operating indicators, and send the target speed limit information to the edge host.

[0078] In order to facilitate the understanding of those skilled in the art, Figure 3 An application environment diagram of a bandwidth control method is provided. Figure 3As shown, the speed limit center can query the current operating indicators of the target domain name on the corresponding edge host in the CDN (Content Delivery Network) monitoring center, and periodically query the total bandwidth corresponding to the target domain name in the monitoring center according to the target domain name. The speed limit center generates the target speed limit information and sends it to the corresponding edge host (the speed-limited component).

[0079] In the above bandwidth control method, speed limit domain name configuration information is read; the speed limit domain name configuration information includes configuration information required for implementing bandwidth control for a target domain name; the bandwidth range of the target domain name includes a pre-control area and a controlled area; the current operating index of the target domain name on the corresponding edge host is queried; the operating index includes at least one of the upstream bandwidth, the downstream bandwidth, the query rate per second data and the current transmission speed corresponding to the target domain name; according to the bandwidth control strategy, the target speed limit information is generated according to the current operating index, and the target speed limit information is sent to the edge host; the bandwidth control strategy includes at least one of a gear speed limit strategy or an adaptive speed limit strategy; the target speed limit information includes the pre-control speed limit information for the pre-control area or the controlled speed limit information for the controlled area.

[0080] In this way, by reading the speed limit domain name configuration information; the speed limit domain name configuration information includes the configuration information required to implement bandwidth control for the target domain name, the bandwidth range of the target domain name can be divided into a pre-control area and a controlled area, based on the speed limit domain name configuration information, query the current operating indicators of the target domain name on the corresponding edge host, according to the bandwidth control strategy, generate the target speed limit information according to the current operating indicators, and send the target speed limit information to the edge host; wherein the bandwidth control strategy includes at least one of the gear speed limit strategy or the adaptive speed limit strategy; wherein the target speed limit information includes the pre-control speed limit information for the pre-control area or the controlled speed limit information for the controlled area, by sending different speed limit information in the pre-control area and the controlled area, the bandwidth is prevented from fluctuating, and the effect of smoothly controlling the bandwidth is achieved, thereby, the actual total amount of user usage can be controlled not to exceed the total amount of restricted bandwidth according to the target speed limit information, prevent individual users from occupying too much bandwidth, allow as many users as possible to access, realize intelligent speed limit of network traffic, relieve the pressure of the source station, and improve the utilization rate of network resources.

[0081] In one embodiment, according to the bandwidth control strategy, target speed limit information is generated according to the current operating indicators, and the target speed limit information is sent to the edge host, including: determining the current total bandwidth corresponding to the target domain name according to the current operating indicators; when the current total bandwidth is greater than the preset gear bandwidth corresponding to the target domain name, generating controlled speed limit information according to the bandwidth control strategy, and sending the controlled speed limit information to the edge host; otherwise, generating pre-controlled speed limit information according to the bandwidth control strategy, and sending the pre-controlled speed limit information to the edge host.

[0082] The controlled speed limit information may refer to the speed limit information for the controlled area.

[0083] The pre-control speed limit information may refer to the speed limit information for the pre-control area.

[0084] The preset gear bandwidth refers to the bandwidth of the highest speed limit gear in the speed limit domain name configuration information.

[0085] For example, if a speed limit gear is configured, the bandwidth of the speed limit gear refers to the preset gear bandwidth;

[0086] If multiple speed limit gears are configured, assuming that gears 1 and 2 are configured, the preset gear bandwidth refers to the gear bandwidth of gear 2. A controlled instruction will be generated only when the current total bandwidth is greater than the bandwidth of the highest speed limit gear, otherwise it is a pre-controlled instruction or no speed limit instruction is generated normally.

[0087] In the specific implementation, the speed limit center generates the target speed limit information according to the bandwidth control strategy and the current operation index, and sends the target speed limit information to the edge host. In other words, the current total bandwidth corresponding to the target domain name can be determined according to the uplink bandwidth and downlink bandwidth in the current operation index.

[0088] Then, if Figure 2 As shown, the speed limit center can determine whether the current total bandwidth corresponding to the target domain name is greater than the preset gear bandwidth corresponding to the target domain name. If the current total bandwidth is greater than the preset gear bandwidth corresponding to the target domain name, the controlled speed limit information is generated according to the bandwidth control strategy, and the controlled speed limit information is sent to the edge host; otherwise, the pre-controlled speed limit information is generated according to the bandwidth control strategy, and the pre-controlled speed limit information is sent to the edge host.

[0089] The technical solution of this embodiment determines the current total bandwidth corresponding to the target domain name according to the current operating indicators; when the current total bandwidth is greater than the preset gear bandwidth corresponding to the target domain name, the controlled speed limit information is generated according to the bandwidth control strategy, and the controlled speed limit information is sent to the edge host; otherwise, the pre-controlled speed limit information is generated according to the bandwidth control strategy, and the pre-controlled speed limit information is sent to the edge host. In this way, by sending different speed limit information in the pre-controlled area and the controlled area, the bandwidth is prevented from fluctuating, and the effect of smoothly controlling the bandwidth is achieved.

[0090] In one embodiment, according to the bandwidth control strategy, the target speed limit information is generated according to the current operating indicators, including: dynamically determining the basic speed limit information corresponding to the edge host according to the preset ratio in the gear speed limit strategy; the basic speed limit information includes at least one of the uplink speed limit value, the downlink speed limit value, the upper query rate per second, or the lower query rate per second; and determining the target speed limit information according to the basic speed limit information corresponding to the edge host.

[0091] The preset ratio may include at least one of an uplink bandwidth ratio, a downlink bandwidth ratio, a QPS upper limit ratio, and a QPS lower limit ratio.

[0092] In a specific implementation, the speed limit center can dynamically determine the basic speed limit information corresponding to the edge host according to the preset ratio in the gear speed limit strategy when generating the target speed limit information according to the current operating indicators in accordance with the bandwidth control strategy; the basic speed limit information includes at least one of the uplink speed limit value, the downlink speed limit value, the upper query rate per second, or the lower query rate per second; thereby determining the target speed limit information based on the basic speed limit information corresponding to the edge host.

[0093] In this way, by dynamically calculating the basic speed limit information, the speed limit center can reasonably allocate bandwidth according to real-time usage and ensure a balance between upstream and downstream traffic. This can avoid the waste of bandwidth resources and improve the overall utilization of the network.

[0094] In actual applications, in combination with the request QPS, a request QPS upper limit (query rate upper limit per second) is set in the pre-control area to prevent bandwidth jitter caused by sudden requests. A request QPS lower limit (query rate lower limit per second) is set in the controlled area to control the number of requests per second to not exceed this value. After exceeding this value, access is denied or 302 scheduling is performed to protect the system from overload and ensure service continuity and stability.

[0095] In one embodiment, if Figure 2 As shown, when it is determined that the current total bandwidth is not greater than the preset gear bandwidth corresponding to the target domain name, in the process of generating pre-control speed limit information according to the bandwidth control strategy, the speed limit center can generate a pre-control instruction when it is determined that the current total bandwidth is not greater than the preset gear bandwidth corresponding to the target domain name, and judge whether the current total bandwidth is greater than the bandwidth threshold of the pre-control area. If not, the basic speed limit information corresponding to the edge host is dynamically determined according to the preset ratio in the gear speed limit strategy, and the basic speed limit information corresponding to the edge host is used as the pre-control speed limit information for the pre-control area.

[0096] In this way, the speed limit parameter values ​​in the pre-control speed limit information (at least one of the uplink speed limit value, the downlink speed limit value, the upper query rate per second value, or the lower query rate per second value) can be used to generate a speed limit information table with domain name and IP granularity and sent to the corresponding edge host.

[0097] In one embodiment, the target speed limit information is determined according to the basic speed limit information corresponding to the edge host, including: when the adaptive speed limit strategy is enabled, determining whether the current request is the first request; if so, using the basic speed limit information as the target speed limit information.

[0098] In the specific implementation, the speed limit center can determine whether to enable the adaptive speed limit strategy when determining the target speed limit information based on the basic speed limit information corresponding to the edge host. If the adaptive speed limit strategy is not enabled, the basic speed limit information corresponding to the edge host is used as the target speed limit information, and the speed limit parameter values ​​in the target speed limit information (at least one of the uplink speed limit value, the downlink speed limit value, the upper query rate per second, or the lower query rate per second) are used to generate a speed limit information table with domain name and IP granularity, which is then sent to the corresponding edge host.

[0099] In practical applications, refer to Figure 2 In the process of generating pre-control speed limit information according to the bandwidth control strategy, when it is determined that the current total bandwidth is not greater than the preset gear bandwidth corresponding to the target domain name, the speed limit center can generate a pre-control instruction when it is determined that the current total bandwidth is not greater than the preset gear bandwidth corresponding to the target domain name, and determine whether the current total bandwidth is greater than the bandwidth threshold of the pre-control area. If so, determine whether to enable the adaptive speed limit strategy. If the adaptive speed limit strategy is not enabled, dynamically determine the basic speed limit information corresponding to the edge host according to the preset ratio in the gear speed limit strategy, and use the basic speed limit information corresponding to the edge host as the pre-control speed limit information for the pre-control area.

[0100] When it is determined that the current total bandwidth is greater than the preset gear bandwidth corresponding to the target domain name, in the process of generating controlled speed limit information according to the bandwidth control strategy, the speed limit center can determine whether to enable the adaptive speed limit strategy. If the adaptive speed limit strategy is not enabled, the basic speed limit information corresponding to the edge host is dynamically determined according to the preset ratio in the gear speed limit strategy, and the basic speed limit information corresponding to the edge host is used as the controlled speed limit information for the controlled area.

[0101] When the adaptive speed limit strategy is enabled, the speed limit center can determine whether the current request is the first request; if so, the basic speed limit information is used as the target speed limit information.

[0102] Specifically, when it is determined that the current total bandwidth is greater than the preset gear bandwidth corresponding to the target domain name, in the process of generating controlled speed limit information according to the bandwidth control strategy, the speed limit center can determine whether to turn on the adaptive speed limit strategy. When the adaptive speed limit strategy is turned on, the speed limit center can determine whether the current request is the first request; if so, the basic speed limit information is used as the controlled speed limit information.

[0103] When it is determined that the current total bandwidth is not greater than the preset gear bandwidth corresponding to the target domain name, in the process of generating pre-control speed limit information according to the bandwidth control strategy, the speed limit center can generate a pre-control instruction when it is determined that the current total bandwidth is not greater than the preset gear bandwidth corresponding to the target domain name, and determine whether the current total bandwidth is greater than the bandwidth threshold of the pre-control area. If so, determine whether to enable the adaptive speed limit strategy. If the adaptive speed limit strategy is enabled, the speed limit center can determine whether the current request is the first request; if so, use the basic speed limit information as the pre-control speed limit information.

[0104] In one of the embodiments, when the current request is not the first request and the current total bandwidth corresponding to the target domain name is greater than the previous total bandwidth corresponding to the target domain name, the target speed limit information is determined according to the basic speed limit information corresponding to the edge host, including: dynamically adjusting the uplink speed limit value and the downlink speed limit value according to the adaptive speed limit strategy; when the adjusted uplink speed limit value and the adjusted downlink speed limit value are less than the minimum speed limit value in the adaptive speed limit strategy, generating the target speed limit information according to the minimum speed limit value.

[0105] The last total bandwidth may be the total bandwidth corresponding to the target domain name obtained by the last query.

[0106] In the specific implementation, when the speed limit center determines whether the current request is the first request, after determining that the current request is not the first request, refer to Figure 2 The speed limit center can determine whether the current total bandwidth corresponding to the target domain name is greater than the last total bandwidth corresponding to the target domain name. If the current total bandwidth corresponding to the target domain name is less than the last total bandwidth corresponding to the target domain name, the current uplink transmission speed and downlink transmission speed of the target domain name are maintained.

[0107] When the current total bandwidth corresponding to the target domain name is greater than the previous total bandwidth corresponding to the target domain name, the uplink speed limit value and the downlink speed limit value can be dynamically adjusted according to the adaptive speed limit strategy; when the adjusted uplink speed limit value and the adjusted downlink speed limit value are less than the minimum speed limit value in the adaptive speed limit strategy, the target speed limit information is generated according to the minimum speed limit value. The speed limit parameter value (minimum speed limit value) in the target speed limit information is used to generate a speed limit information table of domain name and IP granularity, and sent to the corresponding edge host.

[0108] If the adjusted uplink speed limit value and the adjusted downlink speed limit value are greater than the minimum speed limit value, the target speed limit information is generated according to the adjusted uplink speed limit value and the adjusted downlink speed limit value. The speed limit parameter values ​​(adjusted uplink speed limit value and adjusted downlink speed limit value) in the target speed limit information are used to generate a speed limit information table with domain name and IP granularity, and sent to the corresponding edge host.

[0109] In this way, when the adaptive speed limit strategy is turned on, the bandwidth control strategy used to generate speed limit information can be adjusted according to whether it is the first request and whether the current total bandwidth is less than the previous total bandwidth. The bandwidth limitation strategy can be dynamically adjusted according to the actual situation of the network, and the speed limit value can be accurately calculated to achieve a smooth and imperceptible speed limit effect. The actual total usage is controlled not to exceed the total limited bandwidth, which helps users save costs, allows as many users as possible to access, and improves network resource utilization.

[0110] The bandwidth control strategy method proposed in this application supports two strategies: configuring gear speed limit and adaptive speed limit. Only by modifying the configuration, the effect of combining static speed limit and dynamic speed limit can be achieved, and intelligent speed limit of network traffic can be realized. The implementation method is simple and efficient, which can relieve the pressure of the source station, ensure the stability of the source station, improve the accuracy of the speed limit, maximize the processing capacity of the source station, and improve the utilization rate of network resources. Compared with the bandwidth limitation method in the related art, the bandwidth control method provided by this application has higher flexibility and intelligence, can better adapt to changes in the network environment, and meet the speed limit requirements of users in different scenarios.

[0111] In actual applications, different bandwidth control strategies can be customized according to user requirements to display different speed limit effects and meet the diverse needs of users.

[0112] In another embodiment, Figure 4 As shown, a bandwidth control method is provided, which is described by taking the method applied to a speed limit center as an example, and includes the following steps:

[0113] Step S402, read the speed limit domain name configuration information.

[0114] Step S404: Determine the bandwidth threshold of the pre-control area at the lowest speed limit gear according to the threshold ratio of the pre-control area and the speed limit gear parameter.

[0115] Step S406, periodically query the total bandwidth corresponding to the target domain name, and when the total bandwidth corresponding to the target domain name is greater than the bandwidth threshold of the pre-control area under the lowest speed limit gear, query the current operation index of the target domain name on the corresponding edge host.

[0116] Step S408: Determine the current total bandwidth corresponding to the target domain name according to the current operation index.

[0117] Step S410: When the current total bandwidth is greater than the preset gear bandwidth corresponding to the target domain name, the controlled speed limit information is generated according to the bandwidth control strategy, and the controlled speed limit information is sent to the edge host.

[0118] Step S412: Otherwise, generate pre-control speed limit information according to the bandwidth control strategy, and send the pre-control speed limit information to the edge host.
