Since the bandwidth resource is limited, in order to improve the stability and reliability of the network service, it is necessary to dynamically adjust the bandwidth resource through a reasonable allocation strategy, but at the same time, the operation burden of the network service side is also increased. Therefore, the bandwidth resource allocation method of the embodiments of the present application can be used in the network service side to reduce the operation burden of the network service side.

[0060] Figure 1is an optional flowchart of the bandwidth resource allocation method provided by the embodiment of the present application, Figure 1 The method in the method can include but is not limited to steps S101-S104.

[0061] Step S101, obtaining the first bandwidth demand of each online device at the current time;

[0062] Step S102, respectively judging whether the first bandwidth demand of each online device meets the bandwidth demand range of the online device configured in the first bandwidth resource allocation scheme, when the first bandwidth demand of the online device does not meet the bandwidth demand range, marking the online device as a second device;

[0063] Step S103, determining the adjustment demand of the first bandwidth resource allocation scheme according to the second quantity of the second device;

[0064] Step S104, judging whether the adjustment demand is greater than the adjustment demand threshold, when the adjustment demand is greater than the adjustment demand threshold, adjusting the first bandwidth resource allocation scheme to the second bandwidth resource allocation scheme according to the first bandwidth demand of each online device at the current time.

[0065] The steps S101-S104 shown in the embodiment of the present application first obtain the first bandwidth demand of each online device at the current time, when the first bandwidth demand of the online device does not meet the bandwidth demand range, marking the online device as a second device, then determining the adjustment demand of the first bandwidth resource allocation scheme according to the second quantity of all second devices. When the adjustment demand of the first bandwidth resource allocation scheme is greater than the adjustment demand threshold, adjusting the first bandwidth resource allocation scheme to the second bandwidth resource allocation scheme according to the first bandwidth demand of each online device at the current time. The present application determines whether the first bandwidth resource allocation scheme needs to be adjusted based on the quantity of online devices exceeding the bandwidth demand range, and only when the adjustment demand is greater than the adjustment demand threshold, the adjustment of the bandwidth resource allocation scheme is performed, so that the network service side does not need to adjust the bandwidth scheme at each time, thereby reducing the network service side for bandwidth resource allocation operation burden.

[0066] In step S101 of some embodiments, the online device refers to the bandwidth using device connected with the network service side at the current time. Generally, the number of online devices connected with the server of the network service side changes constantly, and meanwhile, the bandwidth demand of the online device changes with the change of user demand when the user operates the device. In the present embodiment, considering that the online device connected with the network service side and the bandwidth demand of the online device change constantly, in order to improve the real-time performance of the bandwidth allocation of the online device, the time period is divided, and the bandwidth resource is adjusted once in a time period. In the present embodiment, the current time can refer to the current time period, that is, the first bandwidth demand of the online device in the current time period is obtained.

[0067] Referring to Figure 2 In some embodiments, step S101 can include but is not limited to steps S201 to S204:

[0068] Step S201, determining the first demand of the online device according to the application startup state of the online device;

[0069] Step S202, determining the second demand of the online device according to the importance level of the online device;

[0070] Step S203, determining the third demand of the online device according to the time interval to which the current time belongs;

[0071] Step S204, determining the first bandwidth demand of the online device according to the first demand, the second demand and the third demand.

[0072] In the present embodiment, the first bandwidth demand of the online device at the current time is determined by multiple influencing factors. By respectively analyzing the demand corresponding to each influencing factor, and then comprehensively calculating the demand of each influencing factor, the accurate first bandwidth demand of the online device is obtained. The multiple influencing factors include but are not limited to the application startup state of the online device, the importance level and the time interval to which the current time belongs, etc.

[0073] In step S201 of some embodiments, the more applications in the online device that need to be networked, the greater the first bandwidth requirement of the online device. Therefore, the present embodiment determines the first requirement of the online device according to the application startup state of the online device. Illustratively, the number of applications in the online device that are in the startup state is counted according to the application startup state of the online device, a corresponding first coefficient is determined according to the first preset interval to which the number of applications in the startup state belongs, the first coefficient is multiplied by a first preset base to obtain the first requirement. For example, when the number of applications in the online device that are in the startup state belongs to the interval [0, S1] (the interval [0, S1] corresponds to the coefficient k1), the first requirement is the coefficient k1 multiplied by the first preset base; when the number of applications in the online device that are in the startup state belongs to the interval (S1, S2) (the interval (S1, S2) corresponds to the coefficient k2), the first requirement is the coefficient k2 multiplied by the first preset base; when the number of applications in the online device that are in the startup state belongs to the interval (S2, +∞), the first requirement is the coefficient k3 multiplied by the first preset base.

[0074] In step S202 of some embodiments, in order to make important devices obtain more bandwidth resources, therefore, when performing bandwidth resource allocation, the second requirement of the online device is determined according to the importance level of the online device, so that the higher the importance level of the online device, the greater the bandwidth requirement. Illustratively, a corresponding second coefficient is determined according to the importance level of the online device, and the second coefficient is multiplied by a second preset base to obtain the second requirement. For example, when the importance level of the online device is I level, the second requirement is the coefficient m1 multiplied by the second preset base; when the importance level of the first device is II level, the second requirement is the coefficient m2 multiplied by the second preset base; when the importance level of the first device is III level, the second requirement is the coefficient m3 multiplied by the second preset base.

[0075] In step S203 of some embodiments, the historical bandwidth usage data of the user device can be counted, the time law of bandwidth usage is obtained according to the historical bandwidth usage data, each time interval in a day is divided into each time interval according to the time law of bandwidth usage, which are: the bandwidth usage peak period, the bandwidth usage flat valley period and the bandwidth usage low valley period, and each time interval is allocated a corresponding third coefficient. For the current time, a corresponding third coefficient is determined according to the time interval to which the current time belongs, the third coefficient is multiplied by a third preset base to obtain a third requirement. For example, when the current time is in the bandwidth usage low valley period, the third requirement of the online device is the coefficient n1 multiplied by the third preset base; when the current time is in the bandwidth usage flat valley period, the third requirement of the online device is the coefficient n2 multiplied by the third preset base; when the current time is in the bandwidth usage peak period, the third requirement of the online device is the coefficient n3 multiplied by the third preset base.

[0076] S1, S2, S3, k1, k2, k3, m1, m2, m3, n1, n2, n3, the first preset base, the second preset base and the third preset base are all preset constants. The first preset base, the second preset base and the third preset base can be the same, for example, all set to 100, or can be different, and the embodiments of the present application do not make specific limitations.

[0077] In step S204 of some embodiments, the first demand amount, the second demand amount and the third demand amount of the online device can be weighted and summed to obtain the first bandwidth demand amount of the online device at the current time. For example, the same or different weights are assigned to the first demand amount, the second demand amount and the third demand amount, and the respective weights corresponding to the first demand amount, the second demand amount and the third demand amount are stored. When calculating the first bandwidth demand amount, the respective weights corresponding to the first demand amount, the second demand amount and the third demand amount are used for weighted summation to obtain the bandwidth demand amount of the online device at the current time.

[0078] In step S102 of some embodiments, the first bandwidth resource allocation scheme refers to the bandwidth resource allocation scheme currently being used or used at the last time, and the bandwidth resource allocation scheme is used to indicate the bandwidth amount required to be allocated by each online device. It is respectively judged whether the first bandwidth demand amount of each online device meets the bandwidth demand range of the online device configured in the first bandwidth resource allocation scheme, wherein the bandwidth amount of each online device is configured in the first bandwidth resource allocation scheme, and on this basis, the bandwidth demand range of each online device can be obtained in combination with the preset redundancy. When the first bandwidth demand amount of the online device does not meet the bandwidth demand range, the online device is marked as a second device; when the bandwidth demand amount of the online device meets the bandwidth demand range, the online device is marked as a first device. In this embodiment, if the first bandwidth demand amount of a certain online device exceeds the bandwidth demand amount range, it indicates that the bandwidth demand amount of the online device has a large variation range, and the bandwidth resource of the online device needs to be dynamically adjusted.

[0079] In step S103 of some embodiments, the number of all online devices marked as the second device, i.e., the second number of the second device, is counted, and the adjustment demand amount of the first bandwidth resource allocation scheme is determined according to the second number of the second device. Generally, the larger the second number, the more devices that need to be adjusted, and the larger the adjustment demand amount of the first bandwidth resource allocation scheme, and the larger adjustment demand amount indicates that the first bandwidth resource allocation scheme needs to be modified.

[0080] Please refer to Figure 3 In some embodiments, step S103 can include but is not limited to steps S301 to S302:

[0081] Step S301, calculating a first ratio of a second quantity of the second devices and a first quantity of the first devices;

[0082] Step S302, determining the first ratio as an adjustment demand of the first bandwidth resource allocation scheme.

[0083] In the embodiment, the second devices are online devices whose first bandwidth demands exceed the bandwidth demand range, and the first devices are online devices whose first bandwidth demands exceed the bandwidth demand range. The first ratio can be a ratio of the quantity of the second devices to the quantity of the first devices. If the first ratio is less than a preset proportion, it indicates that the preset first bandwidth resource allocation scheme can meet the bandwidth demands of most online devices, and there is no need to dynamically adjust the first bandwidth resource allocation scheme.

[0084] In other embodiments, the first ratio can also be a ratio of the quantity of the second devices to the quantity of all online devices, i.e., the second quantity divided by the sum of the first quantity and the second quantity. Similarly, if the first ratio is less than a preset proportion, it indicates that the preset first bandwidth resource allocation scheme can meet the bandwidth demands of most online devices, and there is no need to dynamically adjust the first bandwidth resource allocation scheme.

[0085] In step S104 of some embodiments, it is determined whether the adjustment demand is greater than an adjustment demand threshold. If the adjustment demand is greater than the adjustment demand threshold, it indicates that the first bandwidth resource allocation scheme cannot meet the bandwidth demands of most online devices, and the bandwidth resource needs to be dynamically adjusted. Then, the first bandwidth resource allocation scheme is adjusted to a second bandwidth resource allocation scheme according to the first bandwidth demands of the online devices at the current time, and the bandwidth resource of the server is allocated to the online devices based on the second bandwidth resource allocation scheme. If the adjustment demand is less than or equal to the adjustment demand threshold, it indicates that the first bandwidth resource allocation scheme can meet the bandwidth demands of most online devices, and there is no need for adjustment. Then, the first bandwidth resource allocation scheme is continued to be used for bandwidth resource allocation. It can be understood that the adjustment demand threshold can be flexibly set according to the use scene demand, such as 5%, 10%, 20%, etc., and the embodiment of the present application does not make specific limitation.

[0086] Please refer to Figure 4 In some embodiments, the step of adjusting the first bandwidth resource allocation scheme to the second bandwidth resource allocation scheme according to the first bandwidth demands of the online devices at the current time in step S104 can include, but is not limited to, steps S401 to S403:

[0087] Step S401, constraining the first bandwidth demands of the online devices to obtain second bandwidth demands of the online devices;

[0088] Step S402, determining a bandwidth demand proportion of the online device according to the second bandwidth demand amount of the online device;

[0089] Step S403, determining a second bandwidth resource allocation scheme according to the bandwidth demand proportion of each online device, and replacing the first bandwidth resource allocation scheme with the second bandwidth resource allocation scheme for bandwidth resource allocation.

[0090] In the embodiment, when the adjustment demand amount is greater than the adjustment demand threshold, it is determined that a new second bandwidth resource allocation scheme needs to be generated to replace the original first bandwidth resource allocation scheme for bandwidth resource allocation. When generating the second bandwidth resource allocation scheme, the first bandwidth demand amount of each online device obtained at the current time needs to be combined to generate a second bandwidth resource allocation scheme suitable for the current bandwidth demand.

[0091] Further, in order to reduce the network load imbalance caused by the newly generated second bandwidth resource allocation scheme, and further cause the overload of a single device or path, and affect the stability and reliability of network operation, the first bandwidth demand amount of the online device is subjected to an amplitude limiting constraint to obtain the second bandwidth demand amount of the online device, reducing the imbalance of too much or too little bandwidth resource of a single online device.

[0092] After determining the second bandwidth demand amount of the online device, the second bandwidth demand amounts of all online devices are added to obtain a total demand amount. The second bandwidth demand amount of each online device is divided by the total demand amount to obtain the bandwidth demand proportion of each online device. The second bandwidth resource allocation scheme is determined according to the bandwidth demand proportion of each online device, and the currently applied first bandwidth resource allocation scheme is replaced with the second bandwidth resource allocation scheme to re-perform bandwidth resource allocation.

[0093] Please refer to Figure 5 In some embodiments, step S401 can further include but is not limited to steps S501 to S503:

[0094] Step S501, judging the flag type of the online device, wherein the flag type is one of the first device or the second device;

[0095] Step S502, when the flag type of the online device is the first device, determining the first bandwidth demand amount of the online device as the second bandwidth demand amount;

[0096] Step S503, when the flag type of the online device is the second device, determining the second bandwidth demand amount of the online device by comparing the first bandwidth demand amount of the online device, the upper limit value of the bandwidth demand range, and the lower limit value of the bandwidth demand range.

[0097] In the embodiment, to reduce the situation that some online devices are allocated too much or too little resources, the online device whose first bandwidth demand amount exceeds the preset range needs to be limited, that is, when the first bandwidth demand amount of the online device is greater than the upper limit of the preset range, the bandwidth demand amount of the online device is adjusted to the upper limit of the preset range, and when the first bandwidth demand amount of the online device is less than the lower limit of the preset range, the bandwidth demand amount of the online device is adjusted to the lower limit of the preset range.

[0098] Further, in the case where the preset range is the same as the bandwidth demand range, it is equivalent to need to limit the first device, and in the embodiment, the flag type of the online device can be determined first, when the flag type of the online device is the first device, no limiting is needed, and the first bandwidth demand amount of the online device is directly taken as the second bandwidth demand amount; when the flag type of the online device is the second device, when the first bandwidth demand amount of the online device is greater than the upper limit of the bandwidth demand range, the upper limit is taken as the second bandwidth demand amount of the online device, or when the first bandwidth demand amount of the second device is less than the lower limit of the bandwidth demand range, the lower limit is taken as the second bandwidth demand amount of the online device.

[0099] Please refer to Figure 6 In some embodiments, before step S402, the step of adjusting the first bandwidth resource allocation scheme to the second bandwidth resource allocation scheme according to the first bandwidth demand amount of each online device at the current time in step S104 can further include but is not limited to steps S601 to S603:

[0100] In step S601, the network noise in the network transmission link of the online device is obtained.

[0101] In step S602, the bandwidth adjustment ratio of the online device is determined according to the network noise, wherein the bandwidth adjustment ratio is positively correlated with the network noise.

[0102] In step S603, the bandwidth demand ratio of the online device is corrected according to the bandwidth adjustment ratio, wherein the bandwidth demand ratio is negatively correlated with the bandwidth adjustment ratio.

[0103] In the embodiment, random thermal noise inherent in the network transmission link or impact noise caused by external interference signals and the like can cause data transmission loss, delay or error. If the network noise of a certain network transmission link at the current time is relatively large, the data transmission can be considered to be reduced, and the normal data transmission can be performed after the network noise is reduced. Based on this, after obtaining the bandwidth demand amount of the online device at the current time, the bandwidth adjustment ratio of the online device can also be determined based on the network noise in the network transmission link corresponding to the online device. The bandwidth adjustment ratio is a value between 0 and 1, and the greater the network noise, the greater the corresponding bandwidth adjustment ratio. The adjustment process of the bandwidth demand amount is specifically: multiplying the bandwidth adjustment ratio and the bandwidth demand amount of the online device to obtain the adjustment amount of the bandwidth demand amount of the online device at the current time, and subtracting the adjustment amount of the bandwidth demand amount from the bandwidth demand amount at the current time to obtain the adjusted bandwidth demand amount.

[0104] It can be understood that the above bandwidth demand amount can refer to the first bandwidth demand amount, or can refer to the second bandwidth demand amount, that is, after obtaining the first bandwidth demand amount of the online device at the current time, the first bandwidth demand amount is adjusted through the adjustment process of the bandwidth demand amount, and then the adjusted first bandwidth demand amount of the online device is divided by the total demand amount of all online devices to obtain the bandwidth demand ratio of the online device, and the first bandwidth demand amount is adjusted to adjust the bandwidth demand ratio. After obtaining the first bandwidth demand amount of the online device at the current time, the first bandwidth demand amount is constrained to obtain the second bandwidth demand amount, and the second bandwidth demand amount is adjusted through the adjustment process of the bandwidth demand amount, and then the adjusted second bandwidth demand amount of the online device is divided by the total demand amount of all online devices to obtain the bandwidth demand ratio of the online device, and the second bandwidth demand amount is adjusted to adjust the bandwidth demand ratio. After obtaining the first bandwidth demand amount of the online device at the current time, the first bandwidth demand amount is adjusted through the adjustment process of the bandwidth demand amount, and the first bandwidth demand amount is constrained to obtain the second bandwidth demand amount, and then the second bandwidth demand amount of the online device is divided by the total demand amount of all online devices to obtain the bandwidth demand ratio of the online device, and the first bandwidth demand amount is adjusted to adjust the second bandwidth demand amount, thereby adjusting the bandwidth demand ratio.

[0105] In some embodiments, step S602, determining the bandwidth adjustment ratio of the online device according to the network noise, includes the following steps:

[0106] When the network noise in the network transmission link corresponding to the online device is between the first preset noise value and the second preset noise value, the preset adjustment ratio value is determined as the bandwidth adjustment ratio of the online device;

[0107] When the network noise in the network transmission link corresponding to the online device is greater than or equal to the second preset noise value, the bandwidth adjustment ratio of the online device is determined based on the relative size of the network noise corresponding to the online device and the second preset noise value.

[0108] Specifically, if the network noise in the network transmission link corresponding to a certain online device is less than the first preset noise value, it indicates that the network noise is small and does not affect normal data transmission, and the adjustment of the bandwidth demand of the online device at the current time can be omitted; if the network noise in the network transmission link corresponding to a certain online device is between the first preset noise value and the second preset noise value, it indicates that the network noise will have a small impact on data transmission, and a fixed preset adjustment ratio value can be used to adjust the bandwidth demand of the online device at the current time; if the network noise in the network transmission link corresponding to a certain online device is greater than or equal to the second preset noise value, it indicates that the network noise has a large impact on data transmission, and the bandwidth adjustment ratio can be calculated based on the network noise corresponding to the online device and the second preset noise value, that is, the ratio of the network noise corresponding to the online device to the second preset noise value is taken as the bandwidth adjustment ratio. The greater the network noise corresponding to the first device, the greater the bandwidth adjustment ratio, and the greater the adjustment amount of the bandwidth demand, and the smaller the bandwidth demand after adjustment. The first preset noise value, the second preset noise value and the preset adjustment ratio value are all preset constants.

[0109] Please refer to Figure 7 In some embodiments, the bandwidth resource allocation method of the embodiment of the present application can further include, but is not limited to, steps S701 to S702:

[0110] Step S701, determining whether the allocation update period corresponding to the current time is ended;

[0111] Step S702, when the allocation update period corresponding to the current time is ended, deleting the second device flag of the online device.

[0112] In the embodiment, the time period is divided, and the bandwidth resource is adjusted once in a time period, and the time period is an allocation update period. The end of the allocation update period indicates that the bandwidth allocation of each online device has been completed according to the first bandwidth resource allocation scheme or the second bandwidth resource allocation scheme in the current time period. In order to normally allocate the bandwidth resource in the next allocation update period, the first device flag or the second device flag of the online device can be cancelled.

[0113] According to some embodiments of the present application, the preset first bandwidth resource allocation scheme is used to allocate fixed bandwidth resources to the plurality of online devices, so as to facilitate network management. In actual network operation, the bandwidth demand of the online devices is constantly changing, and the bandwidth resource may be insufficient, and needs to be dynamically adjusted. In order to meet the change of the bandwidth demand of the online devices, and not to increase the network management burden caused by dynamic adjustment too much, the embodiment detects the bandwidth demand of the online devices in real time, and for the online devices, i.e. the second devices, whose bandwidth demand exceeds the bandwidth demand range, the adjustment demand of the first bandwidth resource allocation scheme is represented by calculating the ratio of the second devices to all online devices. If the ratio is less than a preset proportion, it indicates that the first bandwidth resource allocation scheme can meet the bandwidth demand of most online devices, and does not need to be dynamically adjusted. Otherwise, if the ratio is greater than or equal to the preset proportion, it indicates that the first bandwidth resource allocation scheme cannot meet the bandwidth demand of most online devices, and needs to be dynamically adjusted. When adjusting the first bandwidth resource allocation scheme, the bandwidth demand of the online devices obtained at the current time can be constrained first, and then the bandwidth demand is adjusted based on the network noise of the relevant network transmission link. The bandwidth demand ratio of the online devices is calculated based on the adjusted bandwidth demand, and the bandwidth amount allocated to the online devices is determined according to the bandwidth demand ratio. The second bandwidth resource allocation scheme is formed according to the bandwidth amount of each online device, and the allocation scheme is applied.

[0115] A first module is configured to obtain the first bandwidth demand of each online device at the current time.

[0116] A second module is configured to respectively judge whether the first bandwidth demand of each online device meets the bandwidth demand range of the online device configured in the first bandwidth resource allocation scheme. When the first bandwidth demand of the online device does not meet the bandwidth demand range, the online device is marked as a second device.

[0117] A third module is configured to determine the adjustment demand of the first bandwidth resource allocation scheme according to the second quantity of the second devices.

[0118] A fourth module is configured to judge whether the adjustment demand is greater than an adjustment demand threshold. When the adjustment demand is greater than the adjustment demand threshold, the first bandwidth resource allocation scheme is adjusted to a second bandwidth resource allocation scheme according to the first bandwidth demand of each online device at the current time.
