Description

Technical Field

[0001] The embodiments of the present application relate to the field of Internet technology, and specifically to a method and device for collecting service quality data of a heterogeneous network. Background Art

[0002] CDN live streaming is mainly responsible for the distribution of streaming media audio and video streams. It distributes the live streaming of the upstream streaming point into a tree structure to meet the requests of large-scale users. In this distribution process, it is necessary to select a suitable relay room through dynamic routing to connect the upstream streaming and the downstream playback room, so that the entire live streaming can maintain low latency and zero jamming. The basis for dynamic routing is the complete service quality data (Qos data) of the entire network. Currently, there are only Qos data of the three major operators, with a high failure rate.

[0051] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0052] First, the terms involved in one or more embodiments of the present application are explained.

[0053] QoS (Quality of Service) refers to the ability of a network to use various basic technologies to provide better service capabilities for specified network communications;

[0054] QoS data: refers to the indicator that measures the current network service capabilities. In the point live CDN, it is mainly measured by information such as bandwidth, delay (rtt), and packet loss rate (lost);

[0055] Heterogeneous network: refers to a network that has inconsistent access capabilities with the general public network provided by the three major domestic operators (China Telecom, China Unicom, and China Mobile). It mainly includes various small operators (such as China Radio and Television, Wasu, etc.), dedicated line networks (a network that can only interact with other networks at designated aggregation points, otherwise it can only communicate between dedicated lines), dedicated computer rooms (with unequal access restrictions, usually due to restrictions such as firewalls or network routing not supported), etc.

[0056] Figure 1 This is a schematic diagram of a CDN content distribution network, such as Figure 1 As shown in the figure, the CDN content distribution network mainly includes: edge computer room, secondary source station, video cloud edge computing cluster (EC), among which, the video cloud edge computing cluster (EC) receives the original video stream and transmits it to the secondary source station through RTMP or HlsV7 protocol; the secondary source station transmits the video stream to the edge computer room through RTMP protocol or transmits the video stream to the edge computer room through HlsV7 protocol; the edge computer room receives the video stream from the secondary source station, converts the video stream into FLV format and transmits it to FLV users or transmits the video stream in HlsV7 format to HlsV7 users. The traffic cost of CDN live broadcast distribution is determined by the tree structure of distribution, such as Figure 1 As shown in the figure, the black link represents the user's pulled stream, and the red link represents the back-to-source required for the user to pull the stream. The secondary source station needs to be selected based on the QOS data.

[0057] However, network heterogeneity mainly includes the following networks or services, and may have the following problems:

[0058] 1. Small operators: Small operators are generally second-tier operators, that is, they contract certain IP network facilities of different three major operators in different regions, and then package them for commercial activities (for example, Wasu may use China Unicom in Zhejiang and China Telecom in Jiangsu). Therefore, when selecting the second-tier route, it is necessary to detect and select the second-tier source station according to the actual operator corresponding to the small operator used by the current computer room (due to recent changes in operator policies, cross-operator access has become increasingly unstable); another type is that some small operators, in some areas of the computer room, can only be actively accessed by the outside, but not from the inside, and some cannot be accessed from the outside, but can only be accessed from the inside; at the same time, this restriction is not fixed and can be changed;

[0059] 2. Private line network: In order to reduce the cost of public network back-to-source bandwidth, a private line network is built between the secondary source stations. The back-to-source between the secondary source stations can be through the private line network. The private line network can only communicate with the computer room on the private line network. At the same time, the private line may have faults and QoS detection is required. At the same time, some small operators also have private line networks between L1 and L2.

[0060] 3. Dedicated computer room: In addition to carrying video CDN services, some core dedicated computer rooms are mainly used to undertake the core computer room functions of the entire company. All business servers are deployed in this computer room, so the security level of this computer room is very high. Its characteristics are that there is no problem in accessing the outside from the inside, while accessing the inside from the outside can only be accessed through NAT. However, due to availability and other related issues in the computer room, the NAT computer room needs to change configuration frequently, so this type of computer room is generally preferred for internal access. But when this type of computer room encounters some small operators that can only be accessed from the inside, it can only be downgraded to NAT.

[0061] In view of the above problems, the inventors of the present application have proposed a service quality data collection solution for heterogeneous networks through creative work, which is described below in conjunction with specific embodiments:

[0062] Figure 2 A schematic diagram of a process for collecting service quality data of a heterogeneous network according to an embodiment of the present application is shown. The method is executed by a central service detection service. Figure 2 As shown, the method comprises the following steps:

[0063] Step S201, generating a service quality data collection task according to a computer room in a heterogeneous network, wherein the service quality data collection task involves a first computer room and a second computer room, and the computer room level of the first computer room is lower than that of the second computer room.

[0064] Specifically, the central service detection service stores information about all computer rooms in the entire network, including location, network facility attributes, connection status, etc. When receiving a query request sent by the routing service, the central service detection service generates service quality data collection tasks for the two computer rooms based on the current network topology and requirements. These tasks are designed to collect key performance indicators (KPIs), such as bandwidth, latency, packet loss rate, etc., to evaluate and optimize the communication quality between the two computer rooms. The computer room level refers to the level of the computer room in the current network topology. Typically, the computer room level of the first computer room is lower than that of the second computer room, and service quality data collection tasks can be generated from low-level computer rooms to high-level computer rooms.

[0065] Step S202, determining the network facility attributes of the first computer room and / or the second computer room.

[0066] Network facility attributes are key parameters that describe the network service capabilities of the computer room. Network facility attributes include: operator attributes, network attributes, and computer room attributes. Specifically, operator attributes can be divided into: small operators (SO) or large operators (LO). Large operators usually have a wider network coverage and service support capabilities, while small operators may focus on specific regions or industries.

[0067] Network attributes can be divided into: dedicated network (DS) and non-dedicated network (NDS). Dedicated network provides a dedicated channel with high stability and security; while non-dedicated network uses the public Internet, which is lower in cost but may have security risks and instability factors;

[0068] The attributes of computer rooms can be divided into: core dedicated computer room (CD) or non-core dedicated computer room (NCD).

[0069] By querying the database in the central service detection service, the network facility attributes of the first computer room and / or the specific network facility attributes of the second computer room can be obtained. By determining the specific network facility attributes of the first computer room and / or the second computer room, it is convenient to accurately determine the data connection mode between the first computer room and the second computer room in the subsequent process, which directly affects the efficiency and reliability of data transmission.

[0070] Step S203: determining a data connection mode between the first computer room and the second computer room according to network facility attributes of the first computer room and / or the second computer room.

[0071] After determining the network facility attributes of the first computer room and / or the network facility attributes of the second computer room, the data connection mode between the first computer room and the second computer room can be determined according to the network facility attributes of the first computer room and / or the second computer room, wherein the data connection mode reflects the method of establishing a connection and sending data between the first computer room and the second computer room, so that the recipient of the service quality data collection task can be determined through the data connection mode. Common modes include push mode and pull mode, and the data connection mode in this embodiment specifically considers who is connected to whom in what mode. For example, the first computer room is connected to the second computer room in pull mode, and the first computer room receives the service quality data collection task issued by the central service detection service. It should be noted that this is only an example and does not have any limiting effect.

[0072] Step S204: sending a service quality data collection task to the first computer room or the second computer room according to the data connection mode, so that the first computer room collects the service quality data of the second computer room according to the data connection mode.

[0073] After determining the data connection mode between the first computer room and the second computer room, a service quality data collection task can be sent to the first computer room or the second computer room according to the data connection mode, so that the first computer room can collect the service quality data of the second computer room according to the data connection mode, wherein the service quality data collection task can include: adopted protocol information, detection data size, duration, number of retries, etc. The service quality data can include information such as bandwidth, delay (rtt), packet loss rate (lost), etc.

[0074] According to the method provided in the embodiment of the present application, a suitable data connection mode is determined for different heterogeneous networks, so that the service quality data of the heterogeneous networks can be collected. This facilitates route selection based on the collected service quality data of the heterogeneous networks, thereby avoiding customer complaints caused by quality impairment or network accidents.

[0075] Figure 3 A schematic diagram of a process for collecting quality of service data of a heterogeneous network according to another embodiment of the present application is shown. Figure 3 As shown, the method comprises the following steps:

[0076] Step S301: Generate a service quality data collection task according to a computer room in a heterogeneous network, wherein the service quality data collection task involves a first computer room and a second computer room, and the computer room level of the first computer room is lower than that of the second computer room.

[0077] For example, the CDN content distribution network includes: a source station (assuming it is called L3), a secondary source station (assuming it is called L2) and an edge node (assuming it is called L1). At this time, the first computer room is L1 and the second computer room is L2, or the first computer room is L2 and the second computer room is L3. This is only an example and does not have any limiting effect.

[0078] Step S302, determining the network facility attributes of the first computer room and / or the second computer room.

[0079] Step S301-Step S302 and Figure 2 Steps S201 and S202 in the illustrated embodiment are similar and will not be described in detail here.

[0080] Step S303, determine whether the network attributes of the first computer room and the second computer room are the same, and / or, if the operator attributes of the first computer room and the second computer room are both the first operator attributes, determine whether the actual operators corresponding to the first computer room and the second computer room are the same; if the network attributes of the first computer room and the second computer room are different, and / or, the actual operators corresponding to the first computer room and the second computer room are different, execute step S304; if the network attributes of the first computer room and the second computer room are the same, and / or, the actual operators corresponding to the first computer room and the second computer room are the same, execute step S305.

[0081] Normally, a computer room on a dedicated network can only communicate with other computer rooms on a dedicated network, but cannot communicate with computer rooms on a non-dedicated network. In order to avoid detection failure, it is necessary to filter the service quality data collection tasks according to the network attributes of the first computer room and the second computer room after determining the network facility attributes of the first computer room and the second computer room, and delete the service quality data collection tasks whose network attributes of the first computer room are different from those of the second computer room, and only retain the service quality data collection tasks whose network attributes of the first computer room and the second computer room are the same.

[0082] In order to avoid failure caused by cross-operator task detection, it is necessary to filter out service quality data collection tasks that are not from the same operator. Therefore, when the operator attributes of the first computer room and the second computer room are both the second operator attributes (where the second operator attributes are large operators), it is possible to directly determine whether the operator attributes of the first computer room and the second computer room are the same. If they are different, the corresponding service quality data collection tasks are deleted. If they are the same, the corresponding service quality data collection tasks are retained.

[0083] When the operator attribute of the first computer room and the second computer room is the first operator attribute, wherein the first operator attribute is a small operator, it is necessary to first determine the actual operators corresponding to the first computer room and the second computer room, and then determine whether the actual operators corresponding to the first computer room and the second computer room are the same. If they are different, delete the corresponding service quality data collection task; if they are the same, retain the corresponding service quality data collection task.

[0084] Normally, the computer room attributes of the two computer rooms involved in the service quality data collection task will not both be the first preset computer room attributes (i.e., the core computer room). Therefore, the service quality data collection task in which the computer room attributes of the first computer room and the second computer room are both the first preset computer room attributes can be deleted.

[0085] It should be noted that when the room attribute of a certain room is the first preset room attribute (i.e., core room), the operator attribute of the room is the second operator attribute (i.e., large operator), and small operators cannot meet the services required by the core room. By filtering the service quality data collection task, the situation of being unable to connect can be filtered out, thereby improving the detection efficiency of service quality data.

[0086] Step S304, delete the service quality data collection task, and then jump to step S305.

[0087] Step S305, determining whether the network attribute of the first computer room is the first preset network attribute, if so, executing step S306, if not, executing step S307.

[0088] Specifically, the first preset network attribute is a dedicated line network. Here, it is judged whether the network attribute of the first computer room is the first preset network attribute to determine whether the first computer room is a dedicated line computer room. Normally, a dedicated line computer room can only detect the network of a dedicated line computer room. Therefore, when it is determined that the first computer room is a dedicated line computer room, it can be determined that the second computer room with a heavy service quality data collection task is also a dedicated line computer room. Therefore, the pull mode can be adopted and the execution of step S307 can be jumped. When it is determined that the first computer room is not a dedicated line computer room, it can be determined that both the first computer room and the second computer room are not dedicated line computer rooms, and the execution of step S308 can be jumped.

[0089] Generally, network attributes can be divided into first preset network attributes and second preset network attributes (non-dedicated network, also called public network). When it is determined that the network attributes of the first computer room are not the first preset network attributes, it can be determined that the network attributes of the first computer room are the second preset network attributes.

[0090] Step S306: Generate a first data connection mode, where the first data connection mode is to connect the first computer room to the second computer room in a pull mode.

[0091] When it is determined that the network attribute of the first computer room is the first preset network attribute, a first data connection mode can be generated. The first data connection mode is to connect the first computer room to the second computer room in a pull mode. That is, the first computer room needs to pull service quality data from the second computer room, thereby simulating the actual data flow.

[0092] Step S307, determining whether the operator attribute of the first computer room is the first operator attribute, if not, executing step S308; if yes, executing step S309.

[0093] Normally, operator attributes can be divided into first operator attributes (i.e., small operators) and second operator attributes (i.e., large operators). Here, the main purpose is to determine whether the operator attribute of the first computer room is a small operator. Therefore, when it is determined that the operator attribute of the first computer room is not a small operator, its operator attribute can be determined to be a large operator. For network heterogeneity, small operators and core computer rooms are usually mutually exclusive. Therefore, when it is determined that the operator attribute of the first computer room is a small operator, it can be determined that the computer room attribute of the first computer room is a non-core computer room.

[0094] Step S308, if the computer room attribute of the first computer room is the first preset computer room attribute, a first data connection mode and a second data connection mode are generated, wherein the priority of the first data connection mode is higher than the priority of the second data connection mode, the first data connection mode is to connect the first computer room to the second computer room in a pull mode, and the second data connection mode is to connect the second computer room to the NAT address of the first computer room in a push mode.

[0095] Normally, the attributes of a computer room can be divided into the first preset computer room attributes (i.e., the core computer room) and the second preset computer room attributes (i.e., the non-core computer room). For a heterogeneous network, when the operator attribute of the first computer room is a large operator and the network attribute of the first computer room is a non-dedicated line network, the computer room attributes of the first computer room can only be the first preset computer room attributes, i.e., the core computer room.

[0096] Therefore, the first data connection mode and the second data connection mode can be generated according to the priority. The priority of the first data connection mode is higher than that of the second data connection mode. The first data connection mode is to connect the first computer room to the second computer room in a pull mode, that is, the first computer room pulls the service quality data from the second computer room. The second data connection mode is to connect the second computer room to the NAT address of the first computer room in a push mode, wherein the NAT address is a public IP address converted from the private IP address of the first computer room. By connecting to the NAT address of the first computer room, normal connectivity between the computer rooms can be guaranteed, and the second computer room pushes the service quality data to the first computer room.

[0097] Therefore, the priority is to send tasks and subsequently collect service quality data according to the first data connection mode. If the first data connection mode fails, tasks will be sent and subsequent service quality data will be collected according to the second data connection mode. Among them, the push mode is that the second computer room actively initiates the connection with the first computer room, which is consistent with the data transmission direction, thereby simulating the real data flow.

[0098] Step S309, determining whether the operator attribute of the second computer room is the first operator attribute, if so, executing step S306; if not, executing step S310.

[0099] Normally, the operator attribute can be divided into the first operator attribute (i.e., a small operator) and the second operator attribute (i.e., a large operator). Here, the main purpose is to determine whether the operator attribute of the second computer room is a small operator. Therefore, when it is determined that the operator attribute of the second computer room is not a small operator, its operator attribute can be determined to be a large operator. For network heterogeneity, small operators and core computer rooms are usually mutually exclusive. Therefore, when it is determined that the operator attribute of the second computer room is a small operator, it can be determined that the computer room attribute of the second computer room is a non-core computer room. Therefore, when it is determined that the operator attribute of the second computer room is a small operator, the execution of step S306 can be skipped to generate a first data connection mode. The first data connection mode is to connect the second computer room from the first computer room in a pull mode. That is to say, the first computer room needs to pull data from the second computer room, thereby simulating the real data flow.

[0100] Step S310, determining whether the room attribute of the second room is the first preset room attribute, if so, executing step S311; if not, executing step S312.

[0101] When it is determined that the operator attribute of the second computer room is a large operator, it is possible to continue to determine whether the computer room attribute of the second computer room is a core computer room. When the second computer room is a core computer room, step S311 can be executed. When the second computer room is a non-core computer room, it can be determined that the second computer room corresponds to a large operator, and step S312 can be executed.

[0102] Step S311, generate a third data connection mode and a fourth data connection mode, wherein the priority of the third data connection mode is higher than the priority of the fourth data connection mode, the third data connection mode is to connect the first computer room from the second computer room in push mode, and the fourth data connection mode is to connect the NAT address of the second computer room from the first computer room in pull mode.

[0103] Therefore, the third data connection mode and the fourth data connection mode can be generated according to the priority. The priority of the third data connection mode is higher than that of the fourth data connection mode. The third data connection mode is to connect the first computer room from the second computer room in a push mode, wherein the second computer room actively sends the service quality data to the first computer room. The fourth data connection mode is to connect the NAT address of the second computer room from the first computer room in a pull mode, wherein the NAT address is a public IP address converted from the private IP address of the second computer room. By connecting to the NAT address of the second computer room, normal connectivity between the computer rooms can be guaranteed, and the first computer room actively obtains the service quality data of the second computer room from the NAT address of the second computer room.

[0104] Therefore, the priority is to send tasks and subsequently collect service quality data according to the third data connection mode. If the third data connection mode fails, the fourth data connection mode will be used to send tasks and subsequently collect service quality data. Among them, the push mode is that the second computer room actively initiates the connection with the first computer room, which is consistent with the data transmission direction, thereby simulating the real data flow.

[0105] Step S312, generate a first data connection mode and a third data connection mode, wherein the priority of the first data connection mode is higher than the priority of the third data connection mode, the first data connection mode is to connect the first computer room to the second computer room in a pull mode, and the third data connection mode is to connect the second computer room to the first computer room in a push mode.

[0106] Therefore, the first data connection mode and the third data connection mode can be generated according to priority. The priority of the first data connection mode is higher than that of the third data connection mode. The first data connection mode is to connect the first computer room to the second computer room in a pull mode, wherein the first computer room actively obtains the service quality data of the second computer room from the second computer room. The third data connection mode is to connect the second computer room to the first computer room in a push mode, wherein the second computer room actively sends the service quality data of the second computer room to the first computer room.

[0107] Step S313, if the data connection mode is the first data connection mode or the second data connection mode, a service quality data collection task is sent to the first computer room, so that the first computer room collects the service quality data of the second computer room according to the first data connection mode or the second data connection mode; if the data connection mode is the second data connection mode or the third data connection mode, a service quality data collection task is sent to the second computer room, so that the first computer room collects the service quality data of the second computer room according to the second data connection mode or the third data connection mode.

[0108] If the data connection mode is the first data connection mode or the second data connection mode, a service quality data collection task is sent to the first computer room, that is, the first computer room is the source computer room, and the second computer room is the target computer room. After the task is sent, the first computer room can collect the service quality data of the second computer room according to the first data connection mode or the second data connection mode; if the data connection mode is the second data connection mode or the third data connection mode, a service quality data collection task is sent to the second computer room, that is, the first computer room is the target computer room, and the second computer room is the source computer room. After the task is sent, the first computer room collects the service quality data of the second computer room according to the second data connection mode or the third data connection mode. Among them, the source computer room refers to the computer room that receives the generated service quality data collection task, and the target computer room refers to the computer room where the source computer room that executes the task is to detect.

[0109] In an optional implementation of the present application, the data association mode of the last successful collection of service quality data can also be obtained, and then it is determined whether the data association mode of the last successful collection of service quality data is the same as the data association mode determined according to the network facility attributes of the first computer room and / or the second computer room; if different, the data association mode of the last successful collection of service quality data is determined as the data association mode corresponding to this service quality data collection task, and then, according to the data association mode of the last successful collection of service quality data, the service quality data collection task is sent to the first computer room or the second computer room, so that the first computer room collects the service quality data of the second computer room according to the data association mode of the last successful collection of service quality data. Determining the data association mode of this round of service quality data collection tasks in combination with the data association mode of the last round of successful collection of service quality data can improve the association success rate and improve the success rate of service quality data collection.

[0110] According to the method provided in the embodiment of the present application, a suitable data connection mode is determined for different heterogeneous networks, so that the service quality data of the heterogeneous networks can be collected. This facilitates route selection based on the collected service quality data of the heterogeneous networks, avoiding customer complaints due to quality damage or network accidents. The data connection mode of the current round of service quality data collection tasks is determined in combination with the data connection mode of the previous round of successful service quality data collection, which can improve the connection success rate and improve the service quality data collection success rate.

[0111] Figure 4 The structural block diagram of the service quality data collection system for heterogeneous networks is shown in Figure 2. Figure 4As shown, the routing service can send a service quality data query request to the central service detection service for routing. The central service detection service can generate a service quality data collection task based on the service quality data query request, and send it to the corresponding computer room (such as L1CT in the figure). Each computer room reports the detection results (i.e., service quality data) to the central service detection service. The central service detection service can send the service quality data to the routing service for the routing service to perform routing based on the service quality data.
