Description

Background Art

[0002] With the development of Internet technology and the continuous improvement of living standards, people can now download various multimedia applications on the Internet to meet their material and cultural needs, such as novels, music, videos, games, etc.

[0003] In actual download scenarios, the maximum total bandwidth of the total bandwidth occupied by multimedia applications downloaded at each moment determines the bandwidth cost. In order to save this cost, a bandwidth threshold is often set based on the download status of multimedia applications at various moments in the past. However, the number of downloaders at each moment is not constant. For example, during the daily rest period, users often flock to the server to download multimedia applications. At this time, the actual bandwidth occupied by the download can easily exceed the bandwidth threshold, resulting in increased bandwidth costs.

[0004] In the related art, in response to the above situation, the download speed is often limited during the download peak period to achieve bandwidth control, so as to avoid the actual bandwidth exceeding the bandwidth threshold as much as possible; the specific limitation method is to limit the speed of all users in the same proportion based on the ratio of the current actual total bandwidth to the bandwidth threshold.

[0005] However, adopting the above method will cause the speed of users with slow download speed to be limited again, which will seriously affect the download efficiency and reduce the service quality. Summary of the invention

[0040] The beneficial effects of this application are as follows:

[0041] The embodiments of the present application provide a method, device, electronic device and storage medium for controlling download speed. After obtaining the actual download speed of each download object for the download target, the present application assigns each download object to a corresponding download speed interval according to each actual download speed, and then traverses each download speed interval. Each time a download speed interval is read, the sum of the bandwidth occupied by each download object included in the currently read download speed interval and the download speed interval that has been read is calculated to obtain the actual total occupied bandwidth; then, the download speed value corresponding to the currently read download speed interval, that is, the reference download speed, is assumed to be the download speed of each download object in the unread download speed interval set, and the estimated total occupied bandwidth of all download objects in the unread download speed interval set is calculated when the download speed of each download object in the unread download speed interval set is the reference download speed.

[0042] Then, compare the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth with the bandwidth threshold. If it is not greater than the bandwidth threshold, it means that when the unread download speed interval is concentrated and the download speed of each download object is the reference download speed, the total bandwidth occupied by all download objects currently downloading the download target will not exceed the bandwidth threshold. Therefore, the reference download speed can be used as one of the options for the download speed threshold.

[0043] After traversing all download speed intervals, one is selected from all the reference download speeds obtained as the final download speed threshold. This download speed threshold will only limit the speed of download objects whose actual download speed is higher than the threshold, and will not affect download objects whose speed is lower than the threshold. Therefore, the download experience and download efficiency can be improved. During the download peak period, there is a reference download speed whose sum of the actual total occupied bandwidth and the estimated total occupied bandwidth is very close to the bandwidth threshold. This reference download speed can maximize the bandwidth utilization and minimize the number of download objects affected by the speed limit. For download objects with higher download speeds, the speed limit has a relatively low impact, further improving the download experience.

[0061] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the technical solution of the present application, rather than all of the embodiments. Based on the embodiments recorded in the application documents, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the technical solution of the present application.

[0062] The following is an introduction to some concepts involved in the embodiments of the present application.

[0063] Actual download speed: The actual speed at which the relevant data of the download target is downloaded from the Internet or other networks to the download device when the download object downloads the download target through the download device.

[0064] Reference download speed: the download speed value corresponding to the download speed range currently read by the server, where the download speed value is obtained by the server based on the download speed range currently read, and it can be the upper limit value, lower limit value, middle value, etc. of the download speed range.

[0065] Actual total occupied bandwidth: the sum of the actual bandwidth occupied by each download object in the current read download interval set, each read download interval and the reference download interval.

[0066] Estimated total occupied bandwidth: The reference download speed is used as the download speed corresponding to each unread download interval in the current unread download interval set, and the sum of the estimated bandwidths occupied by each download object in the unread download interval set is obtained.

[0067] The following is a brief introduction to the design concept of the embodiment of the present application:

[0068] In an actual download scenario, the more download objects a multimedia application is currently downloading, and the faster the download speed of a single download object is, the greater the total bandwidth occupied by all download objects currently downloading the multimedia application. Furthermore, among the total bandwidths corresponding to each time of the day, the maximum total bandwidth, that is, the daily peak value of the total bandwidth, determines the bandwidth cost. In order to save this cost, a bandwidth threshold is often set in advance, and the actual download speed of the download object is limited during the download peak period, so as to control the total bandwidth occupied by all download objects within the bandwidth threshold as much as possible. However, how to limit the actual download speed has become an increasingly prominent problem.

[0069] In the related technology, the average speed limit method or the proportional speed limit method is usually used to limit the actual download speed of each download object; wherein, the average speed limit method is to divide the bandwidth threshold by the number of download objects currently downloading the download target, and use the calculated result as the speed limit value, which is sent to each terminal device so that the download speed of each download object for the download target does not exceed the speed limit value sent by the server. However, due to the large number of users downloading at the same time during the evening peak, the speed limit value sent by the server will be relatively low. For download objects with a higher actual download speed, their actual download speed will directly drop to the speed limit value, and the download speed limit is more serious, resulting in a poor download experience; and for download objects with a lower actual download speed, due to the limitations of their own equipment or network, the actual download speed itself cannot reach the speed limit value sent by the server. And under this method, after the speed limit, the total bandwidth occupied by all download objects does not reach the bandwidth threshold, so that the bandwidth is not fully utilized, and the objects with a faster actual download speed still have room to improve the download speed.

[0070] The proportional speed limit rule is to limit the speed of all download objects in the same proportion based on the ratio of the total bandwidth occupied by all download objects to the bandwidth threshold. This results in that during peak download periods, download objects with lower actual download speeds will be limited again, resulting in a poor download experience for the download objects, seriously affecting download efficiency and reducing service quality.

[0071] Based on this, the present application proposes a method for controlling the download speed. After obtaining the actual download speed of each download object for the download target, the present application will assign each download object to a corresponding download speed interval according to the actual download speed, and then traverse each download speed interval. Each time a download speed interval is read, the sum of the bandwidth occupied by each download object contained in the currently read download speed interval and the download speed interval that has been read is first calculated to obtain the actual total occupied bandwidth.

[0072] Afterwards, assuming that the unread download speed interval is concentrated, the download speed of all download objects is the reference download speed, and calculate how much bandwidth all download objects in the unread download speed interval will occupy in this case, and then add the actual total occupied bandwidth to the estimated total occupied bandwidth. If the result does not exceed the pre-set bandwidth threshold, it means that the actual download speed of each download object is limited according to the reference download speed, so that the total bandwidth occupied by all download objects currently downloading the download target can be kept within the bandwidth threshold. At this time, the server adds the reference download speed to the download threshold value set.

[0073] After traversing all download speed intervals, the largest one among all reference download speeds obtained can be selected as the final download speed threshold. Since the download speed threshold will only limit the speed of download objects whose actual download speed is higher than the threshold, and will not affect download objects whose actual download speed is lower than the threshold, the download experience and download efficiency can be improved. And since the threshold is the maximum reference download speed, the number of download objects affected by the speed limit can be minimized, and the total bandwidth occupied by all download objects currently downloading the download target is also closest to the bandwidth threshold, achieving full utilization of the bandwidth.

[0074] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application may be combined with each other if there is no conflict.

[0075] like Figure 1 As shown, it is a schematic diagram of an application scenario of an embodiment of the present application. The application scenario diagram includes two terminal devices 110 and a server 120.

[0076] In the embodiment of the present application, the terminal device 110 includes but is not limited to mobile phones, tablet computers, laptop computers, desktop computers, e-book readers, intelligent voice interaction devices, smart home appliances, car terminals and other devices; the terminal device may be installed with a client related to games, music, etc., which may be software (such as a browser, game software, etc.), or a web page, a small program, etc. The server 120 is a background server corresponding to the software or web page, small program, etc., or a server specifically used for download speed control, which is not specifically limited in the present application. The server 120 may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms.

[0077] It should be noted that the download speed control method in each embodiment of the present application can be executed by an electronic device, and the electronic device can be a server 120, that is, the method can be executed by the server 120 alone. With the server 120 as the execution subject, assuming that the current Q game has been updated to a new version, the player needs to download the new version of the game installation package. At this time, each terminal device 110 uploads its actual download speed for the game installation package. After receiving each actual download speed, the server 120 assigns each player who is currently downloading the game installation package to a corresponding download speed interval according to the actual download speed; thereafter, the server reads each download speed interval in a certain order, and each time it is read, the currently read download speed interval is used as a reference download speed interval, and the following operations are performed:

[0078] For each download speed interval that has been read and a download speed interval that is currently being read, the server 120 obtains the actual total occupied bandwidth occupied by all players in these download speed intervals; for each download speed interval that has not been read, the server 120 obtains the reference download speed according to the download speed interval that is currently being read, and obtains the estimated total occupied bandwidth occupied by all players in each download speed interval that has not been read based on the reference download speed. Finally, the server 120 compares the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth with the size of the preset bandwidth threshold. If the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth is not greater than the bandwidth threshold, the reference download speed obtained in the current reading is added to the download threshold value set.

[0079] After traversing all download speed ranges, the server 120 selects a reference download speed from the download threshold value set as the download speed threshold for the game installation package of the Q game, and sends the download speed threshold to each terminal device 110 to limit the maximum actual download speed of each terminal device 110 for the game installation package.

[0080] In an optional implementation, the terminal device 110 and the server 120 may communicate with each other via a communication network.

[0081] In an optional implementation, the communication network is a wired network or a wireless network.

[0082] It should be noted that Figure 1 The figure is only an example. In fact, the number of terminal devices and servers is not limited and is not specifically limited in the embodiments of the present application.

[0083] In an embodiment of the present application, when there are multiple servers, the multiple servers can form a blockchain, and the servers are nodes on the blockchain; as in the download speed control method disclosed in the embodiment of the present application, the download data involved can be saved on the blockchain, for example, the actual download speed, the actual total occupied bandwidth, the estimated total occupied bandwidth, the download threshold value, etc.

[0084] In addition, the embodiments of the present application can be applied to various scenarios, including not only scenarios of download speed control, but also including but not limited to cloud technology, artificial intelligence, smart transportation, assisted driving and other scenarios.

[0085] The following describes the download speed control method provided by the exemplary embodiment of the present application in combination with the application scenario described above and with reference to the accompanying drawings. It should be noted that the above application scenario is only shown to facilitate understanding of the spirit and principles of the present application, and the implementation of the present application is not limited in this respect.

[0086] See also Figure 2 As shown, it is an implementation flow chart of a method for controlling download speed provided in an embodiment of the present application. The specific implementation process of the method is as follows:

[0087] S201: The server assigns each download object to a corresponding download speed interval based on the actual download speed of each download object for the download target.

[0088] In the above, the download target can be a video, a song, a game installation package, etc.; the download object is the object that is currently performing a download operation on the download target; each download device used by each download target can detect its own actual download speed and send the actual download speed to the server; the download device can be a laptop computer, a mobile phone, a desktop computer, etc.; based on this, the server can obtain the actual download speed of each download object currently being downloaded for the download target, or in other words, obtain the actual download speed of each download device currently being downloaded for the download target.

[0089] It can be understood that in the specific implementation of the present application, related data such as the actual download speed of each download object for the download target is involved. When the above embodiments of the present application are applied to specific products or technologies, it is necessary to obtain the permission or consent of the download object, and the collection, use and processing of relevant data need to comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0090] In order to control the download speed in time and adjust the bandwidth, the server can periodically obtain the actual download speed of each download object for the download target, for example, once a minute, or once every half a minute, which is not specifically limited in this application. The following is a specific introduction using one of the acquisitions as an example.

[0091] After obtaining each actual download speed, the server counts the actual download speed distribution of each download object. An optional statistical method is to divide the maximum speed of 100000KB / s into 10000 download speed intervals, and the length of each download speed interval is 10KB / s. For example, the first download speed interval is 0-10KB / s, the second download speed interval is 10-20KB / s, the third download speed interval is 20-30KB / s, ..., and the last download speed interval is 99990-100000KB / s.

[0092] Assuming that an actual download speed is 23KB / s, the download object corresponding to the actual download speed is assigned to the third download speed interval; assuming that another actual download speed is 7KB / s, the download object corresponding to the actual download speed is assigned to the first download speed interval; assuming that an actual download speed is 10002KB / s, 10002KB / s divided by 10KB / s is 1000 plus 2, then the download object corresponding to the actual download speed is assigned to the 1000+1th download speed interval... until all download objects are assigned.

[0093] like Figure 3As shown, it is an actual download speed distribution diagram provided by an embodiment of the present application. After all download objects are assigned according to the above method, an actual download speed distribution diagram with the download speed as the horizontal axis and the number of downloaders as the vertical axis can be approximately obtained.

[0094] It should be noted that each of the above download speed intervals can be open at the beginning and closed at the end (the first download speed interval is closed at the beginning and closed at the end), or closed at the beginning and open at the end (the last download speed interval is closed at the beginning and closed at the end), etc.; and each of the above methods for statistically analyzing the actual download speed distribution is only an example, and this application does not make any specific limitations.

[0095] Taking a specific scenario as an example, suppose a game has just been launched, and a large number of players download the game installation package every day. In order to limit bandwidth costs, the game manufacturer sets the bandwidth threshold to S. Assume that each player only uses one download device to download the game installation package, and the server obtains the actual download speed of each player who is currently downloading the game installation package every minute.

[0096] like Figure 4 As shown, it is a logic diagram for counting the actual download speed distribution of each player provided by an embodiment of the present application. It is assumed that the current server obtains that z players are downloading the download target, that is, there are z actual download speeds, among which the actual download speed corresponding to player 1 is D1 (KB / s), the actual download speed corresponding to player 2 is D2 (KB / s), the actual download speed corresponding to player 3 is D3 (KB / s), the actual download speed corresponding to player 4 is D4 (KB / s), ..., the actual download speed corresponding to player z is Dz (KB / s); the server assigns each download object to the corresponding download speed interval according to each actual download speed.

[0097] There are n download speed intervals in total, and the length of each download speed interval is 10KB / s. Assume that the attribution results of each download object are as follows: the actual download speed D1 (KB / s) corresponding to player 1 is between 10 and 20 (KB / s), so player 1 is attributed to download speed interval 2; the actual download speed D2 (KB / s) corresponding to player 2 is between 10n-20 and 10n-10 (KB / s), so player 2 is attributed to download speed interval n-1; the actual download speed D3 (KB / s) corresponding to player 3 is between 10n-20 and 10n-10 (KB / s), so player 3 is also attributed to download speed interval n-1; the actual download speed D4 (KB / s) corresponding to player 4 is between 10n-10 and 10n (KB / s), so player 4 is attributed to download speed interval n; ...; the actual download speed Dz (KB / s) corresponding to player z is between 0 and 10 (KB / s), so player z is attributed to download speed interval 1.

[0098] S202: The server traverses each download speed interval to obtain a set of download threshold values, wherein each time a download speed interval currently read is used as a reference download speed interval, and the following operations are performed:

[0099] S2021: The server obtains the actual total occupied bandwidth of each download object included in the read download speed interval set.

[0100] In the above, the server traverses each download speed interval in order from low speed to high speed, and the read download speed interval set at least includes the reference download speed interval; when the server reads the first download speed interval this time, the read download speed interval set only includes the reference download speed interval currently being read; when the server does not read the first download speed interval this time, the read download speed interval set includes all the read download speed intervals that have been read before, as well as the reference download speed interval currently being read.

[0101] An optional way to obtain the actual total occupied bandwidth is that the server selects the download speed values ​​corresponding to the reference download speed interval and each read download speed interval from the reference download speed interval and each read download speed interval included in the read download speed interval set; then, the server obtains the actual total occupied bandwidth of each download object included in the read download speed interval set based on the reference download speed interval, the number of download objects corresponding to each read download speed interval, and each download speed value.

[0102] Among them, the download speed value corresponding to a download speed range can be the upper limit value, lower limit value, middle value, etc. of the download speed range, and this application does not make specific limitations.

[0103] In the above, there is the following relationship between the download speed and the occupied bandwidth. A download speed of 1Mb / s will correspond to occupying 1Mb of bandwidth, 1Mb / s=1024Kb / s=128KB / s.

[0104] The actual total occupied bandwidth can be approximately obtained by multiplying the number of download objects by the corresponding download speed value; an optional implementation is that the server can obtain the actual total occupied bandwidth of each download object included in the read download speed interval set based on the reference download speed interval and the sum of the products of the number of download objects corresponding to each read download speed interval and the corresponding download speed value.

[0105] In addition, if the computing power is sufficient, the product of each download object and its corresponding actual download speed in the read download speed interval can be calculated separately, and finally all the products can be added together to obtain the actual total occupied bandwidth; next, this application will still take the multiplication of the number of download objects in each interval by the corresponding download speed value as an example to introduce and explain this application.

[0106] The download speed interval is denoted as i, and the reference download speed interval is denoted as m; x[i] is defined as the download speed value of the i-th download speed interval, and y[i] is defined as the number of downloaders in the i-th download speed interval; assuming that the length of each download speed interval is 10KB / s, and the download speed value is the upper limit of each interval, then x[i] = i×10KB / s; the calculation formula for the actual total occupied bandwidth B1 is as follows:

[0107]

[0108] Following the assumption in S201, after assigning each player to a corresponding download speed interval, the server starts from download speed interval 1 and traverses each download speed interval in order from low speed to high speed; Figure 5 As shown, a logic diagram for obtaining the actual total occupied bandwidth of each download object in the read download speed interval set provided by an embodiment of the present application, assuming that download speed intervals 1 to 3 have been read, and the server is currently continuing to read download speed interval 4, then the current read download speed interval set includes the read download speed interval 1, the read download speed interval 2, the read download speed interval 3, and also includes the download speed interval 4 currently being read, that is, the reference download speed interval 4.

[0109] Assume that the read download speed interval 1 contains y1 players, and the corresponding download speed value is x1; the read download speed interval 2 contains y2 players, and the corresponding download speed value is x2; the read download speed interval 3 contains y3 players, and the corresponding download speed value is x3; the reference download speed interval 4 contains y4 players, and the corresponding download speed value is x4. Then the actual total occupied bandwidth is x1×y1+x2×y2+x3×y3+x4×y4.

[0110] S2022: The server obtains a reference download speed based on the reference download speed interval, and obtains an estimated total occupied bandwidth of each download object included in the unread download speed interval set based on the reference download speed.

[0111] After obtaining the actual total occupied bandwidth of each download object in the read download speed interval set, the server needs to further obtain the estimated total occupied bandwidth of the download speed interval that has not been read. The estimated total occupied bandwidth is different from the actual total occupied bandwidth, which is calculated based on the reference download speed; wherein the reference download speed is the download speed value corresponding to the reference download speed interval; that is, the server uses the download speed value corresponding to the reference download speed interval as the reference download speed of each unread download speed interval in the unread download speed interval set. Afterwards, the server obtains the estimated total occupied bandwidth of each download object contained in the unread download speed interval set based on the number of download objects corresponding to each unread download speed interval and the reference download speed.

[0112] This step is equivalent to determining how much bandwidth all the download objects in the unread download speed interval set will occupy, assuming that the download speeds of all the download objects in the unread download speed interval set are the reference download speed.

[0113] The estimated total occupied bandwidth can also be approximately obtained by multiplying the number of download objects by the reference download speed; an optional implementation is that the server obtains the estimated total occupied bandwidth of each download object included in the unread download speed interval set based on the sum of the products of the number of download objects corresponding to each unread download speed interval and the reference download speed.

[0114] The download speed interval is still recorded as i, and the reference download speed interval is recorded as m; x[i] is defined as the download speed value of the i-th download speed interval, and y[i] is defined as the number of downloaders in the i-th download speed interval; assuming that there are n download speed intervals in total, and the length of each download speed interval is 10KB / s, and the download speed value is the upper limit of each interval, then x[i] = i×10KB / s; the calculation formula for estimating the total occupied bandwidth B2 is as follows:

[0115]

[0116] Using the assumptions in S2021, such as Figure 6 As shown, it is a logic diagram for obtaining the estimated total occupied bandwidth of each download object included in an unread download speed interval set provided by an embodiment of the present application; at this time, the unread download speed interval set includes unread download speed interval 5, unread download speed interval 6, ..., unread download speed interval n-1 and unread download speed interval n; the server uses the download speed value x4 corresponding to the reference download speed interval 4 as the reference download speed, and based on the reference download speed x4, obtains the estimated total occupied bandwidth of each download object in the unread download speed interval set.

[0117] Specifically, the estimated total occupied bandwidth = x4×y5+x4×y6+…+x4×y n-1 +x4×yn .

[0118] S2023: If the server determines that the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth is not greater than the preset bandwidth threshold, the reference download speed is added to the download threshold value set.

[0119] That is, the server adds the actual total occupied bandwidth obtained during this reading process to the estimated total occupied bandwidth, and compares the sum with the preset bandwidth threshold. If the actual total occupied bandwidth + the estimated total occupied bandwidth ≤ the bandwidth threshold, the reference download speed obtained during this reading process, that is, the download speed value corresponding to the reference download speed range currently being read, is added to the download threshold value set.

[0120] The bandwidth threshold mentioned above may be a content delivery network (English: Content Delivery Network, CDN) bandwidth threshold.

[0121] Referring to the calculation formulas of the actual total occupied bandwidth B1 and the estimated total occupied bandwidth B2 in S2022 and S2023, the above process can be recorded as:

[0122]

[0123] Since the server traverses each download speed interval in the order from low to high speed, for each download speed interval in the read download speed interval set, that is, for each read download speed interval and the reference download speed interval, the actual download speed of each download object therein will not exceed the reference download speed; and in the unread download speed interval set, the actual download speed of each download object has exceeded the reference download speed; this formula is equivalent to limiting the download speed of all download objects in the unread download speed interval set to the reference download speed, and calculating how much bandwidth all download objects in the unread download speed interval set will occupy in this case, and then adding the actual total occupied bandwidth to the estimated total occupied bandwidth. If the result does not exceed the preset bandwidth threshold, it means that by limiting the actual download speed of each download object according to the reference download speed, the total bandwidth occupied by all download objects currently downloading the download target can be kept within the bandwidth threshold. At this time, the server adds the reference download speed to the download threshold value set; if the result has exceeded the preset bandwidth threshold, it is not added.

[0124] In addition, when the server reads the last download speed interval this time, the unread download speed interval set is an empty set, and accordingly, the value of B2 is 0.

[0125] Using the assumption in S2022, the server adds the actual total occupied bandwidth obtained to the estimated total occupied bandwidth, that is, x1×y1+x2×y2+x3×y3+x4×y4+x4×y5+x4×y6+…+x4×y n-1 +x4×y n , compare the summed result with the bandwidth threshold S. Assuming that the bandwidth threshold is greater than the summed result, the server does not add x4 to the download threshold value set.

[0126] S203: The server sorts the reference download speeds in the download threshold value set, and uses the reference download speed at a specified position as the download speed threshold for the download target.

[0127] Since the actual download speed of each download object is limited based on any reference download speed in the download threshold value set, the total bandwidth occupied by all download objects currently downloading the download target can be kept within the bandwidth threshold. Therefore, a reference download speed can be obtained in the download threshold value set as the download speed threshold, and the download object whose actual download speed exceeds the reference download speed can be speed-limited, so that its actual download speed does not exceed the reference download speed at most.

[0128] An optional implementation is to use the maximum reference download speed in the download threshold value set as the download speed threshold for the download target.

[0129] By selecting the maximum reference download speed as the download speed threshold, the actual download speed of most download objects will not be affected by the speed limit, provided that the sum of B1 and B2 is within the bandwidth threshold. After the speed limit, the total bandwidth occupied by all download objects can approach the bandwidth threshold, thereby improving bandwidth utilization.

[0130] In addition, the number of downloaders is not static. For example, in a day, the number of downloaders usually increases gradually after 5 pm. For a week, there are more downloaders on Saturdays and Sundays. When the download target launches a new activity or updates the version, the number of downloaders will increase significantly compared to weekdays. In other words, downloads also have peak and trough periods. During the trough period, there are often fewer downloaders, and the total bandwidth occupied by all download objects is far below the bandwidth threshold. At this time, there is no need to limit the speed of the download objects.

[0131] Therefore, after traversing all download speed intervals, the server can determine whether speed limitation is currently required based on the number of reference download speeds in the download threshold value set.

[0132] An optional implementation is that if the server determines that there is a reference download speed that is not added to the download threshold value set, the reference download speeds in the download threshold value set are sorted, and the reference download speed at a specified position is used as the download speed threshold for the download target.

[0133] The server determines that there are reference download speeds that have not been added to the download threshold value set, that is, in the download threshold value set, the number of reference download speeds is less than the number of download speed intervals, which means that the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth is greater than the preset bandwidth threshold. Further, the server obtains the download speed threshold and limits the speed of some download objects.

[0134] On the contrary, if the server determines that there is no reference download speed that has not been added to the download threshold value set, that is, in the download threshold value set, the number of reference download speeds is equal to the number of download speed intervals, then it means that there is no situation where the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth is greater than the preset bandwidth threshold, and no speed limit processing is required.

[0135] In addition, since the server traverses each download speed interval in order from low to high speed, the reference download speed obtained by the server and the sum of B1 and B2 are getting larger and larger. Based on this, the server can directly use the reference download speed that makes the bandwidth threshold less than or equal to the sum of B1 and B2 for the first time as the download speed threshold in the process of traversing each download speed interval.

[0136] That is, each time the server reads a download speed interval, it determines the relationship between the actual total occupied bandwidth corresponding to the read download speed interval set, the sum of the estimated total occupied bandwidth corresponding to the unread download speed interval set, and the bandwidth threshold; if the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth is not greater than the bandwidth threshold, it continues to read the next download speed interval; if the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth is greater than the bandwidth threshold, it stops reading and uses the reference download speed corresponding to the download speed interval as the download speed threshold.

[0137] like Figure 7 As shown, it is a schematic diagram of a download speed threshold value provided in an embodiment of the present application. In a statistical distribution diagram of actual download speed with download speed as the horizontal axis and the number of downloaders as the vertical axis, assuming that the reference download speed that makes the bandwidth threshold less than or equal to the sum of B1 and B2 for the first time is: the download speed value x[m] corresponding to the download speed interval m, then x[m] is directly used as the download speed threshold.

[0138] It should be noted that when using the above method, if when reading the download speed interval m, the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth is equal to the bandwidth threshold, the reference download speed corresponding to the download speed interval m can be used as the download speed threshold; if when reading the download speed interval m, the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth is greater than the bandwidth threshold, and when reading the download speed interval m-1, the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth is less than the bandwidth threshold, then the reference download speed corresponding to the download speed interval m-1 can be selected as the download speed threshold. When the download speed intervals are closely spaced, the reference download speed corresponding to the download speed interval m can also be selected as the download speed threshold. Although selecting the reference download speed corresponding to m may cause the total bandwidth occupied by all download objects to exceed the bandwidth threshold, the excess bandwidth is small.

[0139] In addition, this application uses the case where a download object uses a download device to download as an example. When a download object downloads the download target on multiple download devices, the actual download speeds corresponding to the multiple download devices should be obtained and assigned to the corresponding download speed intervals. For example, assuming that download object a uses two download devices to download the download target, the actual download speeds corresponding to the two download devices are 123KB / s and 133KB / s respectively, and the download speed interval length is 10KB / s, then after attribution, download object a will exist in the 13th interval and the 14th interval at the same time.

[0140] In addition to attributing the download object, the corresponding download device may also be attributed based on the actual download speed, which is not specifically limited in this application.

[0141] In the present application, the server may periodically obtain the actual download speed of each download object for the download target, and obtain the download speed limit value based on each actual download speed to control the bandwidth, for example, obtaining the download speed limit value once per minute.

[0142] Following the assumption in S2023, after reading all n download speed intervals, the server sorts the reference download speeds in the obtained download threshold value set. Assuming that there are n-5 reference download speeds in the download threshold value set, the n-5 reference download speeds are sorted in ascending order, and the sorting results are x1, x2, x3, ..., x4, ..., x5, ..., x6, ..., x7, ..., x8, ..., x9, ..., x10, ..., x11, ..., x12, ..., x13, ..., x14, ..., x15, ..., x16, ..., x17, ..., x18, ..., x19, ..., x21, ..., x22, ..., x3 n-7 、x n-6 、x n-5 , so the server can choose x n-5 As the download speed threshold, the maximum download speed of the game installation package does not exceed x before the server obtains a new download speed limit value next time. n-5 .

[0143] In summary, the present application also provides a download speed control system, such as Figure 8 As shown, it is a schematic diagram of a download speed control system provided in an embodiment of the present application, which includes terminal devices of each download object, a server, and terminal devices of maintenance personnel (or technicians, operators, other relevant staff, etc.) of the download target; the server includes a speed limit module, a database and a decision-making module.

[0144] The terminal device of each download object can report the actual download speed to the speed limit module in real time or periodically. The speed limit module is responsible for collecting, summarizing and counting the actual download speeds reported by the terminal devices, and periodically synchronizing the summarized and counted actual download speeds to the database for storage; the decision module periodically loads each actual download speed in the database, and based on the actual download speed collected by the speed limit module, counts the actual download speed distribution, calculates the download speed threshold, and finally sends the obtained download speed threshold to the database for use by the speed limit module; the speed limit module periodically loads the download speed threshold in the database, and sends the download speed threshold to the terminal device of each download object to limit the user's download speed.

[0145] In addition, the database can transmit the actual download speed, download threshold, bandwidth threshold and other data stored therein to the display module of the maintenance personnel's terminal device. The display module can visualize these data and has a detection and alarm function when the download threshold is too low. The operator can use the data displayed by the display module to make relevant speed limit decisions, such as adjusting the bandwidth threshold, so as to better balance the download experience and operating costs of the download object.

[0146] In addition, in addition to the fact that during the low-peak download period, the total bandwidth occupied by all download objects does not reach the bandwidth threshold, and therefore the actual download speed is not restricted, there is also the situation during the peak download period when the actual download speed has been restricted, but due to the gradual decrease in the number of downloaders, if the actual download speed is still restricted by the download speed threshold obtained last time, the total bandwidth occupied by all download objects will gradually decrease and become lower and lower than the bandwidth threshold. Although it is still the peak download period, the actual download speed is appropriately increased in this case, that is, the download speed threshold is increased to achieve peak shaving and valley filling of the total bandwidth occupied by all download objects.

[0147] like Fig. 9As shown, it is a schematic diagram of a closed-loop feedback system provided by an embodiment of the present application. The terminal device of each download object reports the actual download speed, and the speed limit module transmits the actual download speed to the decision module. The decision module calculates the download speed threshold according to the actual download speed. When the terminal device of each download object uses the download speed threshold sent by the speed limit module to control the actual download speed, the actual download speed can be prevented from exceeding the download speed threshold, thereby affecting the actual download speed of each download object collected by the speed limit module next time. That is, from (1) to (2) to (3) to (4) to (1)... and so on, a closed-loop feedback system is formed, which periodically calculates the download speed threshold and adjusts the actual download speed of each download object, and continuously adjusts it so that the total bandwidth occupied by all download objects continuously approaches the bandwidth threshold.

[0148] like Fig.10 As shown, it is a schematic diagram of a bandwidth control effect provided in an embodiment of the present application. In the upper figure, the horizontal axis is time, and the vertical axis is the total bandwidth occupied by all download objects downloaded to the download target at the corresponding moment; in the lower figure, the horizontal axis is time, and the vertical axis is the number of all download objects downloaded to the download target at the corresponding moment; the bandwidth threshold is set to 400Gb.

[0149] As can be seen from the figure below, the number of download objects gradually increases after 16:00 every day, and the download gradually enters the peak period; speed limits are adopted after 16:00 and before 20:00 on X month 24 and X month 25. As can be seen from the figure above, the total bandwidth basically remains flat after reaching the bandwidth threshold, and does not increase with the increase in the number of download objects. The total bandwidth occupied by all download objects is well limited to the vicinity of the bandwidth threshold, which plays a role in controlling bandwidth and saving bandwidth costs. In addition, the difference between the total bandwidth and the bandwidth threshold is within 3%, and the bandwidth control is precise, which has almost no impact on the download experience of the download objects.

[0150] It can be seen that during the download peak period, this application controls the total bandwidth occupied by all download objects while trying to affect only a small number of download objects with higher actual download speeds, thereby reducing the impact on the download experience of the download objects. After controlling the actual download speed, the total bandwidth occupied by all download objects approaches the bandwidth threshold, thereby achieving full utilization of the bandwidth and further balancing the experience of the download objects and the bandwidth cost.

[0151] An optional implementation is that it is also possible to follow the following Fig.11 The flowchart shown implements S201 to S203, taking obtaining an acquisition cycle as an example, and includes the following steps:

[0152] S1101: The server obtains the actual download speed of each download object for the download target, and assigns each download object to a corresponding download speed interval based on each actual download speed.

[0153] S1102: The server reads a download speed interval, and uses the currently read download speed interval as a reference download speed interval.

[0154] The server reads each download speed interval in sequence from low speed to high speed, wherein the download speed interval currently read is the reference download speed interval.

[0155] S1103: The server obtains the actual total occupied bandwidth of each download object in the read download speed interval set.

[0156] In the above, if the server reads the first download speed interval this time, the read download speed interval set only includes the reference download speed interval currently being read; when the server does not read the first download speed interval this time, the read download speed interval set includes all the read download speed intervals previously read, as well as the reference download speed interval currently being read.

[0157] S1104: The server uses the download speed value corresponding to the reference download speed range as the reference download speed.

[0158] S1105: The server calculates the estimated total occupied bandwidth of each download object included in the unread download speed interval set based on the reference download speed.

[0159] In the above, if the server reads the last download speed interval this time, the unread download speed interval set is an empty set, and accordingly, the value of the estimated total occupied bandwidth is 0.

[0160] S1106: The server determines the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth and the relationship between the sum and the bandwidth threshold. If the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth is less than the bandwidth threshold, S1107 is executed; otherwise, S1108 is executed.

[0161] S1107: The server determines whether the reference download speed interval currently read is the last download speed interval. If so, execute S1109, otherwise return to S1102.

[0162] S1108: The server uses the reference download speed obtained this time as the download speed threshold.

[0163] S1109: The server does not limit the actual download speed.

[0164] like Fig.12As shown, it is a logical schematic diagram of controlling the download speed provided in an embodiment of the present application. The server first obtains the actual download speed of each download object (download object 1, download object 2, download object 3...), and based on the actual download speed, assigns the corresponding download object to the corresponding download speed interval, and obtains the distribution of the download objects corresponding to the actual download speed in each download speed interval. After that, the server traverses each download speed interval (download speed interval 1, download speed interval 2, download speed interval 3...), and each time a download speed interval is read, a corresponding reference download speed can be obtained.

[0165] The reference download speeds are screened. Specifically, if the sum of the actual total occupied bandwidth and the estimated total occupied bandwidth obtained during this reading is not greater than the bandwidth threshold, the reference download speed obtained during this reading can be added to the download threshold value set, otherwise it is not added.

[0166] After traversing all download speed intervals, the final download threshold value set is obtained, which includes reference download speed 1, reference download speed 2, reference download speed 3, etc. A reference download speed is selected from the download threshold value set as the download speed threshold, and the actual download speed of each download object is controlled based on the download speed threshold.

[0167] Based on the same inventive concept, the embodiment of the present application also provides a download speed control device. Fig.13 As shown, it is a schematic diagram of the structure of a download speed control device, which may include:

[0170] The traversal unit 1302 includes: a first acquisition unit 13021, a second acquisition unit 13022, and a storage unit 13023. Each time the data is read, a currently read download speed interval is used as a reference download speed interval, and the following operations are performed:

[0171] The first acquisition unit 13021 is used to obtain the actual total occupied bandwidth of each download object included in the read download speed interval set; the read download speed interval set at least includes a reference download speed interval;

[0175] Optionally, the first acquiring unit 13021 is specifically used for:

[0176] Selecting download speed values ​​corresponding to the reference download speed interval and each of the read download speed intervals from the reference download speed interval and each of the read download speed intervals included in the read download speed interval set;

[0178] Optionally, the first acquiring unit 13021 is specifically used for:

[0179] Based on the reference download speed interval, the sum of the products of the number of download objects corresponding to each read download speed interval and the corresponding download speed value is obtained to obtain the actual total occupied bandwidth of each download object included in the read download speed interval set.

[0180] Optionally, the second acquiring unit 13022 is specifically configured to:

[0183] Optionally, the second acquiring unit 13022 is specifically configured to:

[0184] Based on the sum of the products of the number of download objects corresponding to each unread download speed interval and the reference download speed, the estimated total occupied bandwidth of each download object included in the unread download speed interval set is obtained.

[0185] Optionally, the sorting unit 1303 is specifically configured to:

[0186] If it is determined that there is a reference download speed that is not added to the download threshold value set, the reference download speeds in the download threshold value set are sorted, and the reference download speed at a specified position is used as the download speed threshold for the download target.

[0187] Optionally, the traversal unit 1302 is specifically used for:

[0190] The maximum reference download speed is used as the download speed threshold for the download target.

[0191] For the convenience of description, the above parts are divided into modules (or units) according to their functions and described separately. Of course, when implementing this application, the functions of each module (or unit) can be implemented in the same or multiple software or hardware.

[0192] After introducing the download speed control method and device according to the exemplary embodiment of the present application, next, an electronic device according to another exemplary embodiment of the present application is introduced.

[0194] Based on the same inventive concept as the above method embodiment, an electronic device is also provided in the embodiment of the present application. In one embodiment, the electronic device may be a server, such as Figure 1 In this embodiment, the structure of the electronic device can be as follows: Fig.14 As shown, it includes a memory 1401 , a communication module 1403 and one or more processors 1402 .

The bus 1404 can be divided into an address bus, a data bus, a control bus, etc. For ease of description, Fig.14 The diagram shows that only one thick line is used, but this does not mean that there is only one bus or only one type of bus.

[0200] The memory 1401 stores a computer storage medium, and the computer storage medium stores computer executable instructions, and the computer executable instructions are used to implement the download speed control method of the embodiment of the present application. The processor 1402 is used to execute the above-mentioned download speed control method, such as Figure 2 shown.

[0201] In another embodiment, the electronic device may also be other electronic devices, such as Figure 1 The terminal device 110 shown, or Figure 8 In this embodiment, the structure of the electronic device can be as follows: Fig.15As shown, it includes: a communication component 1510, a memory 1520, a display unit 1530, a camera 1540, a sensor 1550, an audio circuit 1560, a Bluetooth module 1570, a processor 1580 and other components.
