Description

Audio and video transmission performance testing method and device, storage medium and electronic equipment
Technical Field

Background
The WebRTC-based audio/video transmission architecture is applied to a large number of scenarios, and is a real-time voice-video communication architecture based on a browser, and as shown in fig. 1, the architecture is generally composed of a hole server (STUN server), a relay server (TURN server), and a self-built signaling server. The hole punching server acts as a temporary intermediary for the p2p request of the client (Peer), detecting the NAT type and opening a port on the NAT device to allow a response; the TURN server may provide communication relay services for clients (peers) after a p2p connection failure.
When the relay server instance is used as a relay server (TURN server), a tester can construct a large number of call connections to exchange audio and video data with the server through a tester when performing performance test on the relay service of the relay server instance. As shown in fig. 3, in the conventional test, a test opportunity obtains a domain name corresponding to an available relay server instance (TURN service instance) from a signaling service (such as a signaling service cluster), and then resolves a public network IP through DNS and establishes a public network connection with the relay server instance by using the public network IP, so that the test machine is in the same intranet as the tested service, and the test process accesses through an external network, which results in a large amount of public network traffic.
In the current manner, when the performance test is performed on the relay service of the relay server instance, as the load (i.e. the number of call connections) and the test duration required by the test increase, the cost required by the test increases due to the consumption of the public network traffic, resulting in higher test cost.

Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Fig. 1 schematically shows a flow chart of an audio-video transmission performance test method according to an embodiment of the present application. The execution main body of the audio and video transmission performance test method can be any test machine with audio and video transmission capability, such as a computer, a mobile phone, a television, a smart watch, household appliances and the like.
As shown in fig. 1, the audio/video transmission performance test method may include steps S110 to S140.
Step S110, obtaining the domain name corresponding to the relay server instance from the signaling service; step S120, inquiring target domain name resolution information corresponding to the domain name from a local system file, wherein the target domain name resolution information refers to information comprising an intranet protocol address corresponding to the domain name, and the local system file is a file which is locally default and is preferentially used for resolving the network protocol address; step S130, if the target domain name resolution information is found, resolving the intranet protocol address corresponding to the domain name based on the target domain name resolution information; and step S140, establishing connection with the relay server instance according to the intranet protocol address so as to perform performance test on the relay service of the relay server instance.
Referring to fig. 3 and fig. 4, the tester, the signaling service (e.g., signaling service cluster) and the relay server instance (TURN service instance) are located in the same intranet, and the tester, the signaling service (e.g., signaling service cluster) and the relay server instance (TURN service instance) may be located in the same cloud service room. A relay server instance (TURN service instance) is a virtual computing environment that may be comprised of a CPU, memory, system disk, and running operating system.
The testing machine can obtain the information such as the domain name and the account number corresponding to the available relay server instance from the signaling service. The testing machine is provided with a file (namely a local system file) which is used for resolving the network protocol address by default and is preferentially used for inquiring target domain name resolution information corresponding to the domain name from the local system file by default, wherein the target domain name resolution information refers to information comprising the intranet protocol address corresponding to the domain name.
In one embodiment of the present application, the local system file is specifically a Hosts file in the system, where the Hosts file is a system file without an extension, and an association "database" may be established in the system file between the domain name and its corresponding IP address (including an intranet protocol address (intranet IP address) in the present application). The domain name and its corresponding IP address (in this application, the intranet protocol address (intranet IP address)) may form the target domain name resolution information, and the intranet protocol address (intranet IP address) is the IP address corresponding to the relay server instance in the intranet. It will be appreciated that the local system file may also be other configuration files.
If the target domain name resolution information is found, the intranet protocol address corresponding to the domain name can be resolved based on the target domain name resolution information. In step 5 of fig. 4, the TURN connection can be established in the intranet according to the intranet protocol address (e.g., intranet IP of fig. 4) and the relay server instance, so as to avoid the tester from performing step 4 of fig. 3 to establish the TURN connection using the public network IP. Furthermore, the performance test can be performed on the relay service of the relay server instance through the intranet traffic, and the relay service is a program of audio and video transmission processing running on the relay server instance.
In this way, based on the step S110 to the step S140, the local default is preferably used for resolving the local system file of the network protocol address, after the tester obtains the domain name corresponding to the available relay server instance from the signaling service, the tester can query the target domain name resolution information corresponding to the domain name from the local system file, obtain the intranet address corresponding to the domain name through the target domain name resolution information resolution, establish intranet connection with the relay server instance through the intranet address, further, effectively avoid consuming public network traffic when performance test is performed, that is, intercept the public network address of the resolved domain name through the local system file, convert the public network traffic into intranet traffic on the premise of not changing the logic of the tested service itself, and effectively reduce the test cost of the audio/video transmission service performance of the relay service under the WebRTC architecture.
Further alternative embodiments of the steps performed when performing the audio/video transmission performance test under the embodiment of fig. 1 are described below.
In one embodiment, after the querying the target domain name resolution information corresponding to the domain name from the local system file, the method further includes: if the target domain name resolution information is not found, inquiring a public network protocol address corresponding to the domain name from a domain name system server; inquiring the intranet protocol address corresponding to the public network protocol address from an instance information inquiry interface, wherein the intranet protocol address is dynamically updated along with the generation of the relay server instance; generating the target domain name resolution information according to the intranet protocol address and the domain name; and storing the target domain name resolution information in the local system file so that the target domain name resolution information is queried locally from the local system file.
If the tester does not find the target domain name resolution information corresponding to the domain name from the local system file, the tester may further execute step 3 in fig. 4, and query the public network protocol address (such as the public network IP in fig. 4) corresponding to the domain name from the domain name system server (DNS server). And, as shown in step 4 of fig. 4, an intranet protocol address (e.g., intranet IP in fig. 4) corresponding to a public network protocol address (e.g., public network IP in fig. 4) is queried from an instance information query interface, such as the DescriibeInstances interface in fig. 4.
The instance information query interface may be provided by a cloud service provider, and the intranet protocol address in the instance information query interface is dynamically updated along with the generation of the relay server instance, that is, when a relay server instance is generated in the cloud service provider, the public network protocol address and the intranet protocol address corresponding to the generated relay server instance are synchronously updated to the instance information query interface.
Because some relay server examples have the capacity of automatic expansion and contraction, public network protocol addresses and intranet protocol addresses of new relay server examples generated by automatic expansion and contraction are also unpredictable in dynamic change, and intranet protocol addresses (such as intranet IP in fig. 4) corresponding to the public network protocol addresses (such as the public network IP in fig. 4) can be accurately queried through an example information query interface, so that the public network protocol addresses corresponding to the relay server examples are accurately converted into the intranet protocol addresses, namely, the intranet protocol addresses (such as the intranet IP in fig. 4) corresponding to the relay server examples are accurately queried.
According to the intranet protocol address and the domain name combination, target domain name resolution information can be generated and stored in a local system file, and the tester can inquire the target domain name resolution information from the local system file and resolve to obtain the intranet protocol address corresponding to the domain name.
In one embodiment, before the querying the target domain name resolution information corresponding to the domain name from the local system file, the method further includes: if the domain name is acquired, inquiring a public network protocol address corresponding to the domain name from a domain name system server; inquiring the intranet protocol address corresponding to the public network protocol address from an instance information inquiry interface, wherein the intranet protocol address is dynamically updated along with the generation of the relay server instance; generating the target domain name resolution information according to the intranet protocol address and the domain name; and storing the target domain name resolution information in the local system file.
In the foregoing embodiment, if the testing machine does not find the target domain name resolution information corresponding to the domain name from the local system file, the local system file is updated by converting the public network protocol address into the internal network protocol address. In this embodiment, after the domain name corresponding to the relay server instance is obtained, the local system file is updated directly by converting the public network protocol address into the internal network protocol address without querying the local system file, and then the local (i.e. the testing machine) can query the target domain name resolution information from the local system file after updating the local system file.
Specifically, after obtaining a domain name corresponding to a relay server instance, the tester queries a public network protocol address corresponding to the domain name from a domain name system server, queries an intranet protocol address corresponding to the public network protocol address from an instance information query interface, generates target domain name resolution information according to intranet protocol address and domain name combination, and stores the target domain name resolution information in a local system file. When the target domain name resolution information is stored in the local system file, if the generated target domain name resolution information is inconsistent with the target domain name resolution information existing in the local system file or the target domain name resolution information corresponding to the domain name does not exist in the local system file, the target domain name resolution information can be updated and stored in the local system file.
Further, before the domain name is obtained and the public network protocol address corresponding to the domain name is queried from the domain name system server, the method may further include: acquiring the latest generation time of a relay server instance from the signaling service; and determining whether the target domain name resolution information corresponding to the domain name exists in the local system file according to the latest generation time.
The latest generation time of the relay server instance can be synchronously updated in the signaling service, and the testing machine obtains the latest generation time of the relay server instance from the signaling service. According to the latest generation time, if the difference between the latest generation time and the current time in the testing machine is smaller than a preset threshold value, accurate target domain name resolution information corresponding to the domain name exists in the local system file, and further, after the domain name is acquired, the target domain name resolution information corresponding to the domain name can be directly inquired from the local system file.
According to the latest generation time, if the difference between the latest generation time and the current time in the testing machine is greater than or equal to a preset threshold value, it can be determined that target domain name resolution information corresponding to the domain name may not exist in a local system file or the target domain name resolution information corresponding to the domain name may not be accurate, and further, after the domain name is acquired, if the domain name is acquired, a public network protocol address corresponding to the domain name is queried from a domain name system server; inquiring the intranet protocol address corresponding to the public network protocol address from an instance information inquiry interface, wherein the intranet protocol address is dynamically updated along with the generation of the relay server instance; generating the target domain name resolution information according to the intranet protocol address and the domain name; and storing the target domain name resolution information in the local system file to ensure that the accurate target domain name resolution information is successfully obtained from the local system file.
In one embodiment, before the querying the target domain name resolution information corresponding to the domain name from the local system file, the method further includes: displaying an analysis information setting interface according to the setting instruction; and according to the setting operation in the analysis information setting interface, the target domain name analysis information is recorded in the local system file.
The related user can trigger the setting instruction through the preset triggering operation, so that the testing machine responds to the setting instruction to display the analysis information setting interface, the related user can perform setting operation in the analysis information setting interface, open the local system file through the setting operation, and conveniently record target domain name analysis information comprising a domain name and a corresponding intranet protocol address according to requirements.
Further, before the setting operation in the setting interface according to the resolution information, the method may further include: inquiring attribute information of the relay server instance from the instance information inquiry interface; and if the attribute information comprises the capability of not having the capacity expansion and contraction automatically, opening an operation control corresponding to the setting operation in the analysis information setting interface.
The cloud service provider can synchronize the attribute information according to the generated relay server instance in the instance information query interface, the attribute information can indicate whether the relay server instance has the capacity automatic expansion and contraction capability, if the attribute information indicates that the relay server does not have the capacity automatic expansion and contraction capability, an operation control corresponding to the setting operation is opened in the analysis information setting interface, and the user can further allow the setting operation through the operation control.
And generating a relay server instance in the cloud service provider, and synchronously updating the public network protocol address and the intranet protocol address corresponding to the generated relay server instance to the instance information query interface. Because some relay server examples have the capacity of automatic expansion and contraction, the public network protocol address and the intranet protocol address of a new relay server example generated by automatic expansion and contraction are also unpredictable in dynamic change, and when the relay server does not have the capacity of automatic expansion and contraction, related users are allowed to manually perform setting operation through operation controls, so that inaccuracy of the queried intranet protocol address caused by inaccuracy of target domain name resolution information set by the users can be avoided.
In one embodiment, after the establishing a connection with the relay server instance according to the intranet protocol address to perform performance testing on a relay service of the relay server instance, the method further includes: continuously transmitting test audio and video data packets to the relay server instance; and recording transmission performance data of the relay service of the relay server instance for the received test audio and video data packet.
After the testing machine establishes intranet connection with the relay server instance according to the intranet protocol address corresponding to the relay server instance, the testing machine can continuously transmit the test audio and video data packet to the relay server instance by constructing a call, and record transmission performance data of the relay service of the relay server instance on the received test audio and video data packet, such as data packet total number, packet loss number, delay, jitter and the like.
The foregoing embodiments are further described below in connection with a procedure for performing WebRTC audio-video transmission service performance test in a scenario where performance test is performed by applying the embodiment of the audio-video transmission performance test method described in the present application.
Referring to fig. 5, in this scenario, the flow of WebRTC audio/video transmission service performance test may include steps S210 to S2180.
Step S210 to step S220, obtaining the domain name corresponding to the relay server instance from the signaling service. Specifically, in step S210, the testing script in the testing machine requests the signaling interface from the signaling service, and in step S220, the domain name corresponding to the available relay server instance returned by the signaling service is obtained.
After step S220, step S230 is entered to perform a Hosts file update procedure, which may include steps S240 to S2130.
Step 240 to step 250, query target domain name resolution information corresponding to the domain name from a local system file (Hosts file), where the target domain name resolution information refers to information including an intranet protocol address (intranet IP) corresponding to the domain name, and the local system file (Hosts file) is a file that is locally default by the testing machine and is preferentially used for resolving the network protocol address.
If the query result returned in step S250 is: if no query is made (i.e., no target domain name resolution information is found), then steps S260 through S2130 are performed, and step S2140 is followed to enter the TURN connection establishment procedure.
Steps S260 to S2130 may include: if the target domain name resolution information is not found, inquiring a public network protocol address (public network IP) corresponding to the domain name from a domain name system server (DNS server); inquiring the intranet protocol address (intranet IP) corresponding to the public network protocol address (public network IP) from an instance information inquiry interface (DescriibeInstances interface), wherein the intranet protocol address (intranet IP) is dynamically updated along with the generation of the relay server instance; generating target domain name resolution information according to the intranet protocol address (intranet IP) and the domain name; and storing the target domain name resolution information in the local system file so that the target domain name resolution information is queried locally from the local system file.
Specifically, if the target domain name resolution information is not found, in step S260, the performance test script uses the domain name as a call-in script (Proxy script); in step S270 and step S280, the Proxy script queries a public network protocol address (public network IP) corresponding to the domain name from a domain name system server (DNS server). Further, in step S290 and step S2100, the Proxy script queries the instance information query interface (DescriibeInstances interface) for the intranet protocol address (intranet IP) corresponding to the public network protocol address (public network IP). In step S2100, the Proxy script generates target domain name resolution information according to the intranet protocol address (intranet IP) and the domain name, and stores the target domain name resolution information in a local system file. Step S2120 to step S2130, the performance test script knows that the execution was successful (i.e., the target domain name resolution information was successfully updated in the local system file (Hosts file)).
After executing step S2130, going to step S2140 and entering into the TURN connection establishment flow, the test script needs to execute steps S2150 to S2170, steps S2150 to S2160, and queries target domain name resolution information corresponding to the domain name from a local system file (Hosts file), and obtains the intranet protocol address (intranet IP) corresponding to the domain name based on the target domain name resolution information resolution, and then, executing step S2170 can establish TURN connection in the intranet through intranet IP and a relay server instance.
Further, if the query result returned in the step S250 is: if it is found (i.e., the target domain name resolution information is found), then the direct step S2140 goes to the TURN connection establishment procedure. At this time, the test script does not need to execute steps S2150 to S2160, that is, the query result returned in step S250 is: after the query (i.e. the target domain name resolution information is found), the test script can directly resolve and obtain the intranet protocol address (intranet IP) corresponding to the domain name based on the target domain name resolution information, so that step S2170 is directly performed, and TURN connection in the intranet is established through the intranet IP and the relay server instance.
After the TURN connection in the intranet is established with the relay server instance through the performance test script in the tester, performance testing may also be performed in step S2170. The performance test may be performed while continuously transmitting test audio and video data packets to the relay server instance. And in step S2180, recording the test result, that is, recording the transmission performance data of the relay service of the relay server instance for the received test audio/video data packet.
In this scenario, when performance testing is performed, 10 calls are kept with the relay server instance per second by the tester, each call bandwidth is 1.5Mbps, and a comparison test with a duration of 600 seconds is performed. From the following results, it can be confirmed that by adopting the method of the embodiment of the application to realize the test of the traffic from the public network to the internal network, the traffic of the public network generated by the performance test can be effectively reduced, and the test cost is reduced.
Taking a charging standard of a cloud service provider as an example for calculation, if a system that needs to support a call connection with 1000 bandwidths per second maintained at 1.5Mbps is tested, the required cost is:
taking a 24-hour stability test of a real-time audio and video cloud built based on a WebRTC framework as an example, each time of stability test, according to the scheme of the application, the cost can be saved by 11865.23 yuan in terms of flow cost, and the test cost is effectively reduced.
In this scenario, by applying the embodiment of the present application, by converting the public network IP of the relay server instance into the intranet IP address, and adding the method of the target domain name resolution information to the local Hosts file of the tester, the flow generated in the testing process is limited to the intranet flow, so as to greatly reduce the testing cost of the performance test.
