[0034] In terms of software architecture, for common architectures of mobile terminals, such as Linux, Android systems, etc., network traffic can usually be controlled through specific command line tools and kernel modules. In one embodiment of the present application, the network traffic control method can be implemented based on the native architecture of the mobile terminal.

[0035] In terms of hardware structure, the network traffic involved in this application depends on the wireless communication hardware of the mobile terminal. Figure 5 The hardware structure diagram of a mobile terminal according to one embodiment of the present application is shown.

[0039] For further information, see Figure 1 , Figure 1 FIG. 1 is a schematic diagram of the main steps of a network traffic control method according to an embodiment of the present application. Figure 1 As shown, the network traffic control method in the embodiment of the present application mainly includes the following steps S11 to S13.

[0040] Step S11, according to a preset screening rule, screening out a target application that needs to be speed-limited from the multiple applications.

[0041] In one embodiment of the present application, the types of target applications include foreground target applications and background target applications, and the target applications that need to be speed limited are screened out from the multiple applications according to preset screening rules, specifically including the following steps S21-S22: Step S21, obtaining the download network speed of each application in the multiple applications and the network performance index of the foreground application, and the foreground application is included in the multiple applications.

[0042] For mobile terminals, whether the network of the foreground application is smooth has a great impact on the user experience. Therefore, this application uses whether the network of the foreground application is smooth as the key to confirming whether network traffic control is needed, that is, to determine whether its network performance indicators are qualified.

[0043] In one embodiment, the network performance indicator includes at least a retransmission rate and a network transmission delay (RoundTrip Time, RTT), and the method further includes: for each foreground application, when all items in the network performance indicator of the foreground application exceed corresponding preset thresholds, determining that the foreground application is a foreground application with unqualified network performance indicators. In this embodiment, the foreground application whose retransmission rate and RTT both exceed the corresponding preset thresholds is a foreground application with unqualified network performance indicators.

[0044] In other embodiments, the network performance indicator may also include other items, such as packet loss rate. Those skilled in the art may set the specific items included in the network performance indicator according to actual needs.

[0045] However, the network freeze of the foreground application may be caused by the background application, the foreground application, or both. Therefore, it is necessary to determine whether there is a target application that needs to be speed-limited according to different reasons, and further filter the target application, please refer to step S22.

[0046] Step S22, filtering out the target application from the multiple applications; if there is a foreground application whose network performance indicator is unqualified, and the total download speed of the background applications exceeds a preset first speed threshold, all background applications are used as the background target applications; if the download speed of the foreground application whose network performance indicator is unqualified exceeds a preset second speed threshold, the foreground application whose download speed exceeds the second speed threshold is used as the target application.

[0047] Specifically, the detailed steps of selecting the target application from the multiple applications can be found in Figure 6 .

[0048] Figure 6 It is a detailed step flow chart of a network traffic control method according to an embodiment of the present application.

[0049] Step S600, system network access; Step S610, monitor the download network speed of each application and the network performance index of the foreground application; wherein the switching between the foreground and background applications is monitored, and the UID (UserIdentifier) ​​of the foreground and background applications is marked respectively, multiple UIDs are dynamically managed, and the network performance index of the current foreground application is accurately obtained; Step S620, determine whether there is a foreground application with unqualified network performance index, if so, execute step S631; if not, enter result 641, there is no target application; the step S620 is intended to determine whether the current foreground application is running smoothly; Step S631, determine whether the total download network speed of the background application exceeds the preset first network speed threshold; if not, execute step S632, determine whether the download network speed of the foreground application with unqualified network performance index exceeds the preset The second network speed threshold set; if not, enter result 641, there is no target application; if so, enter result 642, there is only a foreground target application; specifically, the foreground target application is a foreground application whose network performance indicator is unqualified and whose download speed exceeds the second network speed threshold; if the judgment result of step S631 is yes, execute step S633 to determine whether the download speed of the foreground application whose network performance indicator is unqualified exceeds the preset second network speed threshold; if not, enter result 643, there is only a background target application; specifically, the background target application is all background applications; if so, enter result 644, there are background target applications and foreground target applications; specifically, the background target application is all background applications, and the foreground target application is a foreground application whose network performance indicator is unqualified and whose download speed exceeds the second network speed threshold.

[0050] The above results 642, 643 and 644 all belong to the existence of target applications.

[0051] In this embodiment, the order of the steps of "determining whether the total download network speed of the background application exceeds the first network speed threshold" and "determining whether the download network speed of the foreground application with unqualified network performance indicators exceeds the second network speed threshold" can be swapped. In other words, this embodiment does not limit the order of the above steps, which will not affect the judgment results of whether there is a target application and what type of target application exists, and can achieve the same technical effect.

[0052] In one embodiment, the download network speed of each application in the multiple applications can be obtained through whole machine monitoring, and the download network speeds of the background applications can be added up to obtain the total download network speed of the background applications; the total download network speed of the background applications can also be obtained by subtracting the total download network speed of the foreground applications from the total download network speed.

[0053] Those skilled in the art can set specific thresholds according to actual needs. For example, please refer to the following Table 1.

[0054] Table 1:

[0055]

[0056] The download network speed of 2M / B shown in Table 1 is the first network speed threshold, the threshold of the retransmission rate in the network performance index is 60%~100%, and the threshold of RTT is 400ms. Specifically, the network transmission delay can be judged using its average value. In one embodiment, it is monitored that the total download network speed in the background is greater than 2MB / S, there are applications in the foreground with a retransmission rate greater than 60%, and an average RTT greater than 400ms. It can be determined that the network of the foreground application is not smooth at this time, and it is caused by the large traffic download of the background application. At this time, it is confirmed that there is a target application that needs to be speed limited, and the target application includes the background target application.

[0057] Step S12: creating a traffic distribution chain according to the target application, and configuring a preset speed limit rule in the traffic distribution chain.

[0058] Compared with upload traffic, download traffic occupies most of the bandwidth. Therefore, if you want to reasonably control network traffic, you need to focus on configuring the download speed of the application.

[0059] In one embodiment of the present application, the download network speed of the target application is limited based on the speed limit rule in the traffic distribution chain.

[0060] In one embodiment, the traffic distribution chain is created according to the target application, and a preset speed limit rule is configured in the traffic distribution chain, including: setting the maximum total download network speed according to the type of the target application, wherein the type of the target application includes a foreground target application and a background target application; performing traffic scheduling according to the maximum total download network speed, and discarding data packets of the target application that exceed the corresponding maximum total download network speed.

[0061] Exemplarily, a first maximum total download network speed may be set for the total download network speed of the background target application, or a second maximum total download network speed may be set for the total download network speed of the foreground target application.

[0062] When traffic is scheduled according to the maximum total download network speed, theoretically the download network speed of the target application should be limited to less than the maximum total download network speed, but in practice, due to uneven data packets sent by the application, there is still a possibility of traffic exceeding the limit. Presetting the discarding (DROP) of data packets of the target application that exceed the maximum total download network speed in the speed limit rule can further ensure the stability of network traffic control.

[0063] Generally, when there is a background target application, it is usually the poor bandwidth configuration of the foreground and background applications that causes the foreground network to freeze; when there is a foreground target application, it is usually the poor download management of individual foreground applications that causes the foreground target application to be unsmooth.

[0064] Furthermore, for foreground applications with poor download management, since the foreground target application includes multiple download links, but usually only a few links are downloading large amounts of data, causing network freezes. Therefore, in addition to setting a maximum download speed, you can further find the specific link that causes network freezes and limit the speed of the download link.

[0065] In one embodiment, the method also includes: if the target application includes a foreground target application, obtaining a target link from multiple download links of the foreground target application, the target link being a link among the multiple download links whose download speed exceeds a preset third speed threshold; setting a corresponding maximum link download speed for the target link; performing traffic scheduling according to the maximum link download speed, and discarding data packets of the target link that exceed the corresponding maximum link download speed.

[0066] Furthermore, in one embodiment of the present application, creating a traffic distribution chain according to the target application and configuring a preset speed limit rule in the traffic distribution chain includes: creating the traffic distribution chain based on an iptables tool.

[0067] Iptables is a common command line tool that can set rules through the kernel's Netfilter framework to manage and control network traffic.

[0068] In other embodiments of the present application, other suitable network traffic management tools, such as nftables, may be selected.

[0069] Taking the Android system as an example, the technical architecture diagram of traffic allocation involved in one embodiment of the present application can be found in Figure 3 .

[0070] Among them, raw, mangle, nat, filter tables, as well as INPUT chain and OUTPUT chain all belong to the system native architecture.

[0071] The raw table is used to set a tag before the data packet enters the connection tracking; the mangle table is used to modify the quality of service (QoS) field of the data packet, or change other data packet header fields; the nat table is used for network address translation; the filter table is used to filter data packets. Through a specific mechanism, the filtered data packets can be sent to the user state for interaction or processing.

[0072] The INPUT chain is used to process all packets entering the local machine, that is, inbound traffic; the OUTPUT chain is used to process all packets sent from the local machine, that is, outbound traffic.

[0073] The architecture also includes matching extension (Matches) modules such as BPF (Berkely Packet Filter), hashlimit (hash limit), owner (owner), statistic (statistics), limit (speed limit), and connmask (link mark).

[0074] Among them, BPF creates a BPF configuration file to identify the UID of the data packet to distinguish between foreground applications and background applications for traffic filtering. The hashlimit module limits the traffic rate based on the hash table; the owner module matches according to the UID of the process to which the data packet belongs. Through these matching extension modules, the matching rules of the data packet can be further refined based on the links of these system native architectures.

[0075] WLAN and rmnet_data are commonly used network interfaces.

[0076] In one embodiment of the present application, creating a traffic distribution chain according to the target application and configuring a preset speed limit rule in the traffic distribution chain also includes: filtering out the target application through a Berkeley packet filter; and setting the speed limit rule for the target application through a hash limit module to limit the download speed of the target application.

[0077] In another embodiment of the present application, the speed limit rules also include outbound speed limit rules, creating a traffic distribution chain according to the target application and configuring preset speed limit rules in the traffic distribution chain, and also including: matching the target application through an owner module; and setting the outbound speed limit rules for the target application through a hash restriction module to achieve limitation on the upload speed of the target application.

[0078] In the terminal device, the target application is filtered through BPF, and its UID or other identification information is matched to ensure that the data packets of the target application are filtered out for speed limiting; the target application is matched through the owner module; hashlimit is used in the traffic distribution chain to set the maximum download speed of the target application. This module monitors the download or upload traffic of the application to ensure that it is within the limited rate range, and discards some data packets that exceed the limit to achieve speed limiting.

[0079] Exemplarily, in one embodiment of the present application, a custom chain nm_TRAFFIC is created as a traffic distribution chain, and its code is as follows: iptables -t filter -N nm_TRAFFIC; iptables -t filter -A INPUT -m bpf--object-pinned / sys / fs / bpf / xxxx -j nm_TRAFFIC; iptables -t filter -A OUTPUT-m owner --uid uid number-j nm_TRAFFIC.

[0080] For example, in one embodiment, if the total download speed is 4000 kb / s, the total download speed of the background application is limited to no more than 50% of the total speed, that is, the hashlimit-upto 2000 kb / s is limited, and packets exceeding the limit are DROP processed.

[0081] When the actual download speed of the target application exceeds the set maximum total download speed, the excess data traffic is DROP processed, that is, the data packets are discarded, thereby effectively controlling the traffic usage of the application to ensure the reasonable allocation and use of network resources.

[0082] In actual operation, for a target application that needs to be speed-limited, an allowed burst flow rate, namely hashlimit-burst, can also be set for it. Based on the maximum flow rate and the allowed burst flow rate, the flow rate of the target application that exceeds the limit is DROP processed.

[0083] Set the allowed burst traffic, that is, allow the target application to exceed the maximum traffic limit in a short period of time. Taking the token bucket algorithm as an example, burst traffic is controlled by accumulating "tokens" and generating a certain number of tokens at regular intervals. The duration of the burst period is related to the size of the token bucket and the generation speed. Generally, traffic peaks between a few hundred milliseconds and a few seconds can be considered short-term burst traffic.

[0084] Step S13: limiting the speed of the target application based on the speed limiting rule in the traffic distribution chain.

[0085] In one embodiment of the present application, the speed limiting of the target application based on the speed limit rule in the traffic distribution chain includes: redirecting the inbound traffic of the mobile terminal to the traffic distribution chain, and limiting the download speed of the target application based on the speed limit rule in the traffic distribution chain.

[0086] In one embodiment, the inbound traffic is redirected to the traffic distribution chain via an INPUT chain.

[0087] By connecting the traffic distribution chain to the INPUT chain of the system's native architecture, it helps to flexibly implement real-time traffic control, and can apply speed limit rules in the early stage of data processing, directly filter and limit download traffic, avoid burdening the system before the traffic enters other links, and improve the overall traffic management efficiency of the system.

[0088] Furthermore, the upload speed of the terminal device can also be managed and controlled to more comprehensively control network traffic.

[0089] In one embodiment, the speed limit rule also includes an outbound speed limit rule, and the method also includes: jumping the outbound traffic of the mobile terminal to the traffic distribution chain, and limiting the upload speed of the target application in the traffic distribution chain based on the outbound speed limit rule.

[0090] The outbound speed limit rule can refer to the above speed limit rule and be set according to actual conditions.

[0091] In one embodiment, outbound traffic is redirected to the traffic distribution chain via an OUTPUT chain.

[0092] Furthermore, the method also includes: if there is no foreground application whose network performance indicator is unqualified, and there is a speed limit rule being executed, then canceling the speed limit rule being executed.

[0093] In one embodiment, creating a traffic distribution chain according to the target application and configuring a preset speed limit rule in the traffic distribution chain further includes determining whether the same target application is currently executing the speed limit rule before issuing the speed limit rule.

[0094] Please continue reading Figure 6 If the target application (641) does not exist, execute step S651 to determine whether the speed limit rule is being executed; if not, return to continue to execute step S610 to monitor the download speed of each application and the network performance indicators of the foreground application; if so, execute step S661 to release the speed limit rule being executed; if the target application (642, 643, 644) exists, execute step S652 to determine whether the same target application is currently executing the speed limit rule; if not, execute step S662 to issue the speed limit rule; if so, execute step S663 to maintain the speed limit rule.

[0095] In one embodiment, when executing the above-mentioned network traffic control method, further, at every preset period, it is re-determined whether there is a target application that needs to be speed limited based on the download network speed of each application in the current multiple applications and the network performance index of the foreground application, and the speed limit rule is dynamically adjusted based on the result of the re-determination. The dynamic adjustment includes setting a new speed limit rule for the re-determined target application, releasing the current speed limit rule, or maintaining the current speed limit rule.

[0096] Exemplarily, the interval period is 3 to 30 seconds.

[0097] The above technical solution implements unified traffic control on applications, which can easily handle all traffic of applications without the tedious processing of each single link, avoiding too many rules that lead to slower data distribution and increased system load; by further monitoring the network speed and link quality of the foreground application, when the user is stuck due to uneven traffic distribution, the network speed is dynamically allocated and deallocated.

[0098] When adopting the above technical solution, this application performs unified traffic control on applications based on the download speed of each application and the network performance indicators of the foreground application. The unified speed limit rules make the network traffic load distributed evenly and faster, solving the problem of low efficiency and untimely traffic distribution in the existing market.

[0099] This application performs network traffic control based on the ptables tool and native INPUT chain, OUTPUT chain, etc., without the need to introduce virtual network devices, further improving the speed of network traffic control.

[0100] Furthermore, this application also provides an example of a complete network traffic control process, please refer to Figure 2 .

[0101] Figure 2 It is a detailed step flow chart of a network traffic control method according to an embodiment of the present application.

[0102] Since the foreground and background APPs are often switched during the use of the mobile terminal, step S211 can be executed after the process is started to monitor the switching of the foreground and background APPs, and mark the UIDs of the foreground APP and the background APP respectively to dynamically manage multiple UIDs.

[0103] After the system is connected to the network in step S221, step S212 is executed to monitor the network performance indicators of the foreground APP. In this embodiment, the retransmission rate and RTT of the foreground APP are monitored. In step S213, if the retransmission rate and RTT increase and exceed the preset threshold, it is judged that the foreground APP is stuck, and the current network speed is further monitored.

[0104] On the other hand, after the system network is connected in step S221, step S222 is executed to monitor the network speed of the whole machine. Specifically, the monitoring of the network speed of the whole machine includes monitoring the download network speed of all APPs running on the mobile terminal. In step S223, if the total download network speed of the background application is greater than the preset threshold, and a large-traffic application is currently downloading, the current foreground APP retransmission rate and RTT are obtained.

[0105] Step S230, obtaining the download network speed of each application and the network performance index of the foreground application.

[0106] In some embodiments of the present application, instead of steps S211 to S223, the download network speed of the entire machine, the retransmission rate and RTT of the foreground application may also be monitored simultaneously.

[0107] Step S231, determining whether there is a target application that needs speed limiting.

[0108] Exemplarily, if it is determined that a target application exists, step S233 is further executed to determine whether the same target application is executing the speed limit rule; if it is not obtained that the same target application is executing the speed limit rule, step S242 is executed to issue the speed limit rule; if the same target application is executing the speed limit rule, step S243 is executed to maintain the speed limit rule.
