Fig. 3 is a device interaction flowchart provided based on the implementation scenario provided in fig. 1, and the flowchart illustrates an interaction flow among a terminal, a quality monitoring server, and a target node device. Referring to fig. 3, the method includes the following steps:

in step 301, a quality monitoring server acquires communication data between a plurality of terminals and a plurality of first node devices.

In the embodiment of the present disclosure, the quality monitoring server is configured to provide, for the plurality of terminals, communication quality with the plurality of first node devices according to communication data between the plurality of terminals and the plurality of first node devices. The plurality of first node devices are servers serving the plurality of terminals in the content distribution network, and the communication data may be used to indicate timeliness of the plurality of terminals for acquiring content through the plurality of first node devices, and the like. In some embodiments, when the content acquired by the plurality of terminals is an audio/video, the communication data may also be used to indicate fluency of playing the audio/video by the plurality of terminals, and as an example, the communication data may be an interval duration between two adjacent frames of audio/video played by any terminal.

Taking the communication data as an example of the time delay for any terminal to acquire the corresponding content through any first node device, after any terminal acquires the corresponding content through any first node device, the quality monitoring server may acquire the time delay for any terminal to acquire the corresponding content through any first node device. In some embodiments, any terminal may further obtain other communication data with any first node device, which is not limited herein in this disclosure. Furthermore, the quality monitoring server may store the acquired communication data between the plurality of terminals and the plurality of first node devices in a data queue, for example, the quality monitoring server may store the communication data in a distributed data queue Kafka (Kafka), so that a subsequent quality monitoring server may quickly acquire corresponding communication data from the data queue.

According to the quality monitoring server, the communication data between the plurality of terminals and the plurality of first node devices are acquired, so that the quality monitoring server can collect a large amount of communication data, and further, the corresponding node devices can be more accurately distributed to each terminal according to the large amount of communication data.

In step 302, the quality monitoring server divides the communication data with the same attribute into a group, and obtains a plurality of groups of communication data.

In the embodiments of the present disclosure, the attribute may be used to indicate network access information, hardware information, and the like of each terminal, and as an example, the attribute may be used to indicate an area where each terminal is located, a corresponding communication operator, a used network type or a terminal type, and the like. In some embodiments, the attribute may also be used to represent other information, and the embodiments of the present disclosure are not limited herein. Each set of communication data is used to indicate the quality of communication between a first node device and a set of terminals having the same attribute. For example, the process of obtaining multiple sets of communication data by the quality monitoring server may include the following steps 302A to 302B:

302A: and the quality monitoring server divides the terminals with the same attribute into a terminal group according to the number and the name of the preset attribute.

In some embodiments, the number of the attributes preset in the quality monitoring server may be 3, and the names of the preset 3 attributes may be an area, a communication operator, a network type, and a terminal type, respectively, so that the quality monitoring server may divide terminals having the same attribute into the same terminal group according to the area where each terminal is located, the communication operator to which the terminal belongs, the network type used, and each terminal type, that is, the quality monitoring server may divide terminals corresponding to the same [ area, communication operator, network type, and terminal type ] into the same terminal group. In some embodiments, the names of the preset 3 attributes may be province, communication operator, network type, and terminal type, respectively, for example, the quality monitoring server may divide terminals corresponding to [ shandong, unicom, 3G, mobile phone ] into the same terminal group. In some embodiments, the quality monitoring server may also divide the plurality of terminals into a plurality of terminal groups according to other attribute quantities and attribute names, which is not limited herein in this disclosure.

302B: the quality monitoring server divides communication data between each terminal in the same terminal group and the same first node device into the same group of communication data to obtain multiple groups of communication data.

In some embodiments, the quality monitoring server may perform data cleaning and aggregation calculation on the communication data between the multiple terminals in the multiple terminal groups and the multiple first node devices by using a distributed processing engine Flink with minutes as a calculation window, so as to achieve the purpose of dividing the communication data between each terminal in the same terminal group and the same first node device into the same group of communication data and obtaining multiple groups of communication data.

The above steps 302A to 302B are a process in which the quality monitoring server obtains a plurality of groups of communication data based on communication data between the plurality of terminals and the plurality of first node devices, and through this process, the quality monitoring server may group the obtained communication data between the plurality of terminals and the plurality of first node devices, so that the quality monitoring server analyzes each group of communication data from the global perspective with a group of communication data as a unit, so as to predict the communication quality between each terminal group and one first node device, thereby avoiding inaccuracy caused by predicting the communication quality of one first node device only through communication data between one terminal and one first node device.

In a possible implementation manner, the quality monitoring server may obtain the communication data between the plurality of terminals and the plurality of first node devices in real time, and therefore, the quality monitoring server may group the obtained communication data every preset time period, for example, the quality monitoring server may group the obtained communication data every one minute, and the quality monitoring server may group the obtained communication data every one second, so as to update each group of the first communication data in time. In some embodiments, the quality monitoring server may also establish a plurality of groups according to the number and name of preset attributes, and then, each time the quality monitoring server acquires the communication data between one terminal and one first node device, the quality monitoring server may store the communication data between the one terminal and one first node device in the corresponding group according to the attribute of the one terminal, which is not limited herein.

In step 303, the quality monitoring server divides each set of communication data into communication data of a plurality of quality levels.

In the disclosed embodiment, the plurality of quality levels are used to indicate the communication quality of each set of communication data.

As an example, the quality monitoring server may set a plurality of different quality thresholds for evaluating quality levels of the communication data, and according to the plurality of different quality thresholds, the quality monitoring server may determine a plurality of different quality levels, and further, the quality monitoring server may compare the size of each group of communication data with the plurality of different quality thresholds, thereby dividing each group of communication data into communication data respectively corresponding to the plurality of different quality levels.

Taking each group of communication data as content acquisition duration between each terminal in the corresponding terminal group and the plurality of first node devices as an example, the quality monitoring server may set a plurality of different quality thresholds as a first duration threshold, a second duration threshold and a third duration threshold, the quality monitoring server may divide communication data greater than the third duration threshold in each group of communication data into first-level quality, divide communication data greater than the second duration threshold and less than or equal to the third duration threshold in each group of communication data into second-level quality, divide communication data greater than the first duration threshold and less than or equal to the second duration threshold in each group of communication data into third-level quality, and divide communication data less than or equal to the first duration threshold in each group of communication data into fourth-level quality. In some embodiments, the quality represented by the first-order quality to the fourth-order quality is higher and higher. In other embodiments, the quality monitoring server may also divide each group of communication data into communication data of multiple quality levels in other manners, which is not limited herein in this disclosure.

In step 304, the quality monitoring server sets the quality class with the largest data amount of the communication data as the first communication quality of each set of communication data.

In the disclosed embodiment, the first communication quality of each group of communication data is used to indicate the communication quality between the corresponding terminal group and one first node device.

As an example, based on communication data of a plurality of quality levels obtained for each set of communication data, the quality monitoring server may detect the number of communication data at each quality level, determine a target quality level at which the data amount of the communication data is the largest, and the quality monitoring server may use the target quality level as the first communication quality of each set of communication data. Taking a plurality of different quality grades corresponding to a group of communication data as first-level quality, second-level quality, third-level quality and fourth-level quality, respectively, as an example, if the quality monitoring server detects that the communication data under the first-level quality is the most, the quality monitoring server may use the first-level quality grade as the first communication quality of the group of communication data.

In the above steps 303 to 304, the quality monitoring server determines the first communication quality of each group of communication data by dividing the quality level of each group of communication data, and through this process, the quality monitoring server divides similar communication data into the same quality level, and further, the quality level is used to represent the first communication quality of each group of communication data, so that the first communication quality can be represented more quickly.

In some embodiments, the quality monitoring server may further obtain the first communication quality of each set of communication data in other manners, for example, the quality monitoring server may analyze each set of first communication data through a time series prediction method, and as an example, the quality monitoring server may analyze each set of first communication data through an ARIMA model (differential Integrated Moving Average Autoregressive model) to obtain the first communication quality of each set of first communication data.

Taking as an example that each group of communication data is a corresponding terminal group, and the content acquisition duration and the playing pause duration of the audio and video are acquired by one first node device for multiple times, the specific process of analyzing each group of first communication data by the quality monitoring server through the ARIMA model to obtain the first communication quality of each group of communication data may be as follows:

in some embodiments, the playing pause duration is an interval duration between two adjacent frames of an audio and video played by the terminal. The quality monitoring server can calculate an average value A of each content acquisition time length in each group of communication data and an average value B of each playing card pause time length in each group of communication data, and further, the quality monitoring server can calculate a first communication quality C of each group of communication data according to the following formula: in some embodiments, A, B, C may be any rational number, and a, B, and C may be any non-zero rational number, for example, a may be 10 and B may be 8.

The above steps 303 to 304 are processes of analyzing, by the quality monitoring server, each group of communication data to obtain the first communication quality of each group of communication data. In a possible implementation manner, the quality monitoring server may analyze each group of the first communication data every preset time period, so that the first communication quality number value of each group of the first communication data is updated in time.

The foregoing steps 301 to 304 are processes in which the quality monitoring server obtains the first communication quality between each terminal group and each first node device according to the communication data between each terminal group and each first node device, and similarly, the quality monitoring server may obtain a plurality of first communication qualities between a plurality of terminal groups and a plurality of first node devices, which is not described in detail herein in this disclosure. Similar to the above steps 301 to 304, in other embodiments, the quality monitoring server may further obtain the first communication quality between each terminal and the plurality of first node devices according to the communication data between each terminal and the plurality of first node devices, which is not limited herein in this disclosure.

Through the steps 301 to 304, the quality monitoring server may analyze the first communication quality corresponding to each group of communication data by acquiring the communication data between the plurality of terminals and the plurality of first node devices, so as to achieve the purpose of predicting the communication quality of each first node device from the global perspective, and increase the data availability of the actual system. Therefore, each terminal can accurately select the first node equipment with higher communication quality according to each first communication quality, so that corresponding content can be efficiently acquired from the selected first node equipment with higher communication quality, and the content acquisition efficiency is improved. Furthermore, each terminal may also select a node device with a poor communication quality from the first node devices according to the first communication qualities, so as to avoid using the node device with the poor communication quality to obtain corresponding content subsequently.

In step 305, the quality monitoring server transmits the first communication quality of each group of communication data to each terminal in the corresponding terminal group.

In step 306, for any terminal, the terminal receives a first communication quality sent by the quality monitoring server, where the first communication quality is used to indicate communication quality between a terminal group to which the terminal belongs and a plurality of first node devices.

In the embodiment of the present disclosure, the terminal may be any one terminal belonging to any one terminal group.

In step 307, the terminal probes a second communication quality with a plurality of second node devices.

In the embodiment of the present disclosure, the plurality of second node devices may be a plurality of servers of a plurality of operators in the content distribution network, and the second communication quality may be a communication quality with the plurality of second node devices that is actively detected by the terminal.

As an example, the terminal may obtain, through the network diagnostic tool, a time delay between the terminal and each second node device, so that the terminal may use the time delay between the terminal and each second node device as the second communication quality between the terminal and each second node device. In some embodiments, the network diagnostic tool may be a PING (Packet Internet Groper), and the delay refers to a time required for a message sent by the network diagnostic tool on the terminal to be transmitted to a second node device. In some embodiments, the terminal may further obtain other data between the terminal and a plurality of second node devices as the second communication quality, and the embodiments of the present disclosure are not limited herein.

As an example, the terminal may analyze Domain names of each CDN operator in the content delivery network through an HTTP (HyperText Transfer Protocol) DNS (Domain Name System) and a Local DNS (Local DNS) respectively to obtain a plurality of Server (Server) IPs (Internet Protocol addresses) corresponding to the Domain names of each CDN operator, the terminal may sequentially detect a time delay between the Server IPs through PING, in some embodiments, each Server IP corresponds to one second node device, and the time delay detected by the terminal between one Server IP is a second communication quality between the terminal and one second node device.

In a possible implementation manner, the terminal may detect the second communication quality with the plurality of second node devices every preset time period, and obtain the latest second communication quality in time, so that the accuracy of the second communication quality is improved, and thus, a subsequent terminal can obtain corresponding content more efficiently. In some embodiments, the preset time period may be one minute, and the preset time period may also be one second.

Through the process of step 307, the terminal may detect the second communication quality with the plurality of second node devices in an active detection manner, and through the process, the terminal may accurately acquire the second communication quality with each second node device, so that the terminal may preferentially select the plurality of second node devices according to the second communication quality. Furthermore, by analyzing the domain name of each CDN operator, the terminal can obtain the Server IP of each second node device in advance before acquiring the content acquisition request, thereby avoiding that the terminal fails to acquire the content after acquiring the content acquisition request because the domain name of the CDN operator may be failed to be analyzed.

In step 308, the terminal determines at least one third node device from the plurality of first node devices.

In this disclosure, the third node device may be a first node device with a first communication quality inferior to a first standard quality, and the first standard quality may be a lower quality level preset by the terminal.

Taking the form that each first communication quality received by the terminal is a quality class as an example, a specific process of the terminal determining at least one third node device may be as follows: the terminal compares each received first communication quality with the first standard quality, and takes the first node corresponding to each first communication quality with the quality level lower than the first standard quality as the at least one third node device. Taking each first communication quality received by the terminal as a first-level quality, a second-level quality, a third-level quality, a fourth-level quality, a fifth-level quality and a sixth-level quality, where the first standard quality is the fourth-level quality, the terminal may determine, from the plurality of first node devices, each first node device corresponding to the first-level quality, the second-level quality and the third-level quality as each third node device. In some embodiments, the terminal may further compare the first communication quality in other forms with the first standard quality in other forms to determine at least one third node device, and the disclosed embodiment is not limited herein.

In some embodiments, the terminal may determine the at least one third node device from the plurality of first node devices after probing the second communication quality between the terminal and the plurality of second node devices. In other embodiments, the terminal may also determine the at least one third node device from the plurality of first node devices in a process of detecting a second communication quality between the terminal and the plurality of second node devices, which is not specifically limited herein.

Through the process of step 307, the terminal may determine, from the plurality of first node devices, at least one third node device with lower communication quality according to the first communication quality corresponding to the plurality of first node devices acquired by the quality monitoring server, so that when the terminal subsequently acquires content from the node device, the at least one third node device with lower communication quality may be removed, thereby improving the efficiency of content acquisition.

In step 309, the terminal determines at least one fourth node device from the plurality of second node devices.

In this embodiment of the disclosure, the at least one fourth node device may be a second node device with a second communication quality better than a second standard quality, and the second standard quality may be a higher quality preset by the terminal.

In some embodiments, the terminal may determine, after detecting the second communication quality between the terminal and the plurality of second node devices, whether there is a second node device with a second communication quality better than a second standard quality in the plurality of second node devices, if so, the terminal may determine that the second node device with the second communication quality better than the second standard quality is the at least one fourth node device, and if not, the terminal may directly use any fifth node device as the target node device, where the any fifth node device is any first node device with the first communication quality better than the third standard quality.

In some embodiments, the terminal may determine, during the process of detecting the second communication quality between the terminal and the plurality of second node devices, whether a second node device with a second communication quality better than a second standard quality exists in the at least one second node device that has been detected, if so, the terminal may determine the second node device with the second communication quality better than the second standard quality as the at least one fourth node device, and if not, the terminal may directly use any fifth node device as the target node device.

Taking the second communication quality between the terminal and the plurality of second node devices after the terminal detects the second communication quality, a specific process of the terminal determining the at least one fourth node device from the plurality of second node devices may be as follows: the terminal may detect the time delay between the terminal and the plurality of second node devices, compare the time delay between the terminal and the plurality of second node devices with a preset time delay, and determine the second node device corresponding to each time delay smaller than the preset time delay as the at least one fourth node device. In the process of detecting the second communication quality between the terminal and the plurality of second node devices, the terminal may also determine the at least one fourth node device in the above manner. In other embodiments, the terminal may also determine the at least one fourth node device by other manners, which is not limited herein in this disclosure.

Through the process, the terminal can screen the high-quality node equipment from the second node equipment, so that the terminal can acquire corresponding content from the high-quality node equipment, the accuracy of selecting the node equipment by the terminal is greatly improved, and the content acquisition efficiency of the terminal is further improved.

In step 310, if there are remaining fourth node devices after the terminal removes the at least one third node device from the at least one fourth node device, determining any remaining fourth node device as the target node device.

The target node device is a server to be served for the terminal in the content distribution network.

In some embodiments, if the terminal detects that there is a common node device with the at least one third node device in the at least one fourth node device, the terminal may remove the common node device with the at least one third node device from the at least one fourth node device, and if there are remaining fourth node devices after removing the common node device with the at least one third node device from the at least one fourth node device, the terminal determines any remaining fourth node devices as the target node device. Wherein the common node device with the at least one third node device refers to a node device that is both in the at least one third node device and in the at least one fourth node device.

Any remaining fourth node device is determined as the target node device by the terminal, so that the communication quality of the target node device determined by the terminal is higher, the fluency of communication between the terminal and the target node device is extremely high, the delay degree is also extremely low, and the accuracy of the target node device determined by the terminal is improved as much as possible.

In some embodiments, if the terminal detects that there is no common node device with the at least one third node device in the at least one fourth node device, the terminal may determine whether communication between the terminal and the quality monitoring server is normal currently, and if communication between the terminal and the quality monitoring server is normal currently, the terminal may determine at least one fifth node device from among the plurality of first node devices, and the terminal may determine any of the fifth node devices as the target node device; if the communication between the terminal and the quality monitoring server is not normal, the terminal may determine any fourth node device from at least one fourth node device as the target node device. Wherein the at least one fifth node device is the first node device whose first communication quality is better than the third standard quality.

Through this procedure, the terminal may determine any one of the fourth node devices or any one of the fifth node devices as the target node device in a case where there is no common node device with the at least one third node device in the at least one fourth node device. And the terminal may preferentially determine any fifth node device as the target node device under the condition that the communication between the terminal and the quality monitoring server is normal, and since the fifth node device is a high-quality node device obtained through a large amount of communication data between the terminal and the first node device, which is obtained by the quality monitoring server, the high-quality node device determined by the quality monitoring server is more accurate, and thus the target node device determined by the terminal is more accurate. If the communication between the terminal and the quality monitoring server is not normal, at this time, the accuracy of the fifth node device obtained through the communication data obtained by the quality monitoring server may not be high, so that, under this condition, the fourth node device obtained by the terminal through active detection is more accurate, and at this time, the target node device obtained by the terminal through any fourth node device is more accurate, and the communication quality is higher.

The second proof mass and the third proof mass may be the same or different, and the embodiment of the present disclosure is not limited herein.

In some embodiments, if there are no remaining fourth node devices after the at least one third node device is removed from the at least one fourth node device, the terminal may determine whether the communication between the terminal and the quality monitoring server is normal, and if the terminal detects that the communication between the terminal and the quality monitoring server is not normal, the terminal may determine any fourth node device from the at least one fourth node device as the target node device.

Through the process, under the above condition, when the terminal detects that the communication between the terminal and the quality monitoring server is abnormal, the terminal may determine that the first communication quality acquired through the quality monitoring server at this time is not accurate enough, and at this time, the accuracy of the target node device determined by the terminal through at least one fourth node device is higher, so that the fluency and the delay degree of the communication between the terminal and the target node device are higher and lower.

In some embodiments, if there is no fourth node device left after the at least one third node device is removed from the at least one fourth node device, and the terminal detects that the communication between the terminal and the quality monitoring server is normal, the terminal may determine at least one fifth node device from the plurality of first node devices, and the terminal may determine any fifth node device as the target node device.

Through the process, under the above conditions, when the terminal detects that the communication between the terminal and the quality monitoring server is normal, the determined high-quality node device is more accurate based on the communication data between a large number of terminals and a plurality of first node devices acquired by the quality monitoring server, so that the target node device determined by the terminal is more accurate, the communication quality between the terminal and the target node device can be improved, the communication smoothness between the terminal and the target node device is higher, the delay is lower, and the content acquisition efficiency of the terminal is greatly improved.

In step 312, when the terminal receives the content acquisition request, the terminal acquires the content corresponding to the content acquisition request from the target node device.

As an example, the terminal may determine a Server IP of the target node device, and when the terminal detects a trigger operation on a web page address, the terminal may trigger a content acquisition request corresponding to the web page address, and the terminal may replace a domain name in the web page address with the Server IP of the target node device to obtain a new web page address, so that the terminal may send the content acquisition request to the target node device based on the new web page address, and the target node device may acquire content corresponding to a content identifier according to the content identifier carried in the content acquisition request, so that the target node device may send the content to the terminal.

Further, in the embodiment of the present disclosure, the terminal may select, according to the first communication quality passively acquired by the quality monitoring server and between the terminal and the plurality of first node devices, a plurality of third node devices with inferior first communication quality from the plurality of first node devices, the terminal may select, according to the second communication quality of the plurality of second node devices actively detected by the terminal itself, at least one fourth node device with superior second communication quality from the plurality of second node devices, and further, the terminal may remove the third node device from the at least one fourth node device to determine the target node device from the remaining fourth node devices with superior communication quality, based on the above process, the terminal may comprehensively screen each node device according to the data passively acquired by the quality monitoring server and the data actively detected by the terminal, thereby achieving the purpose of determining the target node device, the accuracy of the terminal in determining the target node equipment is greatly improved, the communication quality of the terminal in acquiring the related content is optimized, and the content acquisition efficiency of the terminal is improved. Furthermore, the quality monitoring server can group and analyze the acquired communication data between the plurality of terminals in the plurality of regions and the plurality of first node devices at the minute-level granularity, and the terminal can also complete the detection of the communication quality of the plurality of second node devices at the minute-level granularity, so that the target node devices can be optimized for large-scale online users at the same time. In addition, the terminal can respond to the content acquisition request at millisecond granularity, so that the response agility of the content acquisition request is improved, and the robustness of the terminal for acquiring the content is greatly improved. Taking the content acquired by the terminal as the video as an example, through the above process, the time taken from the terminal to acquire the video acquisition request to the terminal to acquire the corresponding video can be reduced by more than 30%, and the pause rate of the terminal for playing the video can be reduced by more than 16%.
