Detailed Description
The present disclosure is described in further detail below with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
It should be noted that, in the present disclosure, the embodiments and features of the embodiments may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 illustrates an exemplary system architecture 100 to which embodiments of the live method or live apparatus of the present disclosure may be applied.
As shown in fig. 1, the system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105. Network 104 may be the medium used to provide communication links between terminal devices 101, 102, 103 and server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
The terminal devices 101, 102, 103 interact with a server 105 via a network 104 to receive or send messages or the like. Various communication client applications, such as a web browser application, a live application, a search application, an instant messaging tool, a mailbox client, social platform software, and the like, may be installed on the terminal devices 101, 102, and 103.
The terminal apparatuses 101, 102, and 103 may be hardware or software. When the terminal apparatuses 101, 102, 103 are hardware, various electronic apparatuses having a communication function are possible.
The server 105 may be a server that provides various services. For example, the server 105 may be a background server that provides support for domain name resolution requirements on the terminal devices 101, 102, 103. The background server may analyze and otherwise process data such as the domain name resolution request, and feed back a processing result (e.g., an internet protocol address) to the terminal device. Alternatively, the server 105 may be a domain name resolution server. As another example, the server 105 may be a backend server that provides support for domain name resolution requirements on the terminal devices 101, 102, 103. The background server can also store live video data, analyze and process data such as a pull stream request and feed back a processing result (such as live video data) to the terminal equipment.
It should be noted that the live broadcast method provided by the embodiment of the present disclosure is generally executed by the terminal devices 101, 102, and 103, and accordingly, the live broadcast apparatus is generally disposed in the terminal devices 101, 102, and 103.
The server may be hardware or software. When the server is hardware, it may be implemented as a distributed server cluster formed by multiple servers, or may be implemented as a single server. When the server is software, it may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services), or as a single piece of software or software module. And is not particularly limited herein.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
Referring to fig. 2, a flow 200 of one embodiment of a method of live broadcasting is shown. The embodiment is mainly exemplified by applying the method to an electronic device with certain computing capability, and the electronic device may be the terminals 101, 102, 103 shown in fig. 1. The live broadcast method comprises the following steps:
In this embodiment, an executing entity (for example, the terminal shown in fig. 1) of the live broadcast method may select an internet protocol address from a set of internet protocol addresses acquired in advance in response to a pull stream generation request.
Generally, in the live broadcast field, a live broadcast provider can send a push streaming request to a server by using a client, wherein the push streaming request comprises live broadcast video data; the server stores live video data; a live viewer can send a pull stream request to a server by using a client, wherein the pull stream request can comprise a live provider identifier of a live provider which the live viewer wants to view; the server may return live video data to the live viewer in response to receiving the pull stream request.
In the prior art, generally, after a pull flow request is generated, a domain name resolution request is started to be sent to a server. The server returns the IP address to the client, and the client sends a pull request by using the IP address which is returned by the server. Therefore, it can be seen that sending the domain name resolution request each time a pull stream request is generated and sent results in a delay in sending the pull stream request, and further results in a failure of the client to obtain live video data quickly.
In this embodiment, the execution subject may generate the pull stream request in response to receiving an operation of a preset control (for example, an opening operation of a preset live window) by a user.
In this embodiment, the ip address in the ip address set may indicate an electronic device for storing live video data.
Alternatively, the electronic device for storing live video data may be a separate server.
Alternatively, the electronic device for storing live video data may be an edge node of a content distribution network. The website can store data by using a Content Delivery Network (CDN), so that bottlenecks and links on the internet, which may affect the data transmission speed and stability, are avoided as much as possible, and Content transmission is faster and more stable. The content distribution network may include edge nodes.
In this embodiment, the ip address may be selected from the ip address set using various policies.
Optionally, the internet protocol address may be selected from the internet protocol address set by using a random selection method.
Alternatively, the internet protocol address may be selected from the internet protocol address set in a polling manner. For example, the ip address set has two ip addresses, and the execution entity sends the pull request by using the two ip addresses in turn.
It should be noted that after the pull request is generated, the internet protocol address is selected from the pre-obtained internet protocol address set, so that domain name resolution is avoided when the pull request is sent, and therefore, when the pull request is sent, the time for domain name resolution is saved, and further, the pull request can be sent as soon as possible, and the speed of obtaining live video data is improved.
In this embodiment, an executing entity (for example, the terminal shown in fig. 1) of the live broadcasting method may send a pull stream request by using the selected internet protocol.
Here, the pulling request is sent by using the selected internet protocol address, and it is understood that the pulling request is sent to the device indicated by the selected internet protocol address.
It should be noted that, the manner provided by the present application may directly obtain the internet protocol address after generating the pull request, instead of obtaining the internet protocol address after sending the domain name resolution request, and may provide a live broadcast manner in which live broadcast video data is obtained faster, that is, a new live broadcast manner is provided.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the live method according to the present embodiment. In the application scenario of fig. 3:
first, the terminal 301 selects an ip address from a set of ip addresses acquired in advance in response to a pull request. Here, the internet protocol address in the above-mentioned set of internet protocol addresses indicates an electronic device for storing live video data.
Then, the terminal 301 may send a pull request using the selected ip address. Here, the pull request may be sent to the electronic device 302 indicated by the picked-up internet protocol address.
In the method provided by the embodiment of the present disclosure, an internet protocol address is selected from a set of internet protocol addresses acquired in advance by responding to a request for generating a pull stream, where the internet protocol address in the set of internet protocol addresses indicates an electronic device for storing live video data; the selected internet protocol address is used for sending the pull flow request, and the technical effects at least comprise that:
first, a new live mode is provided.
Secondly, after the pull stream request is generated, the internet protocol address is selected from the internet protocol address set acquired in advance, and domain name resolution is avoided when the pull stream request is sent, so that the time of domain name resolution is saved when the pull stream request is sent, the pull stream request can be sent as soon as possible, and the speed of acquiring live video data is improved.
With further reference to fig. 4, a flow 400 of yet another embodiment of a live method is shown. The process 400 of the live broadcasting method includes the following steps:
In this embodiment, an execution subject (e.g., the terminal shown in fig. 1) of the live broadcast method may send a domain name resolution request including a domain name in response to determining that a preset trigger condition is satisfied.
In this embodiment, the website indicated by the domain name stores data via a content distribution network.
In this embodiment, a preset trigger condition may be used to trigger generation and sending of a domain name resolution request.
In this embodiment, the preset trigger condition may include, but is not limited to, at least one of the following: application startup, network system switching, and expiration of Time To Live (TTL).
Here, the application start in the trigger condition may refer to a live broadcast client start installed on the terminal.
Herein, the network system may refer to a network type. The network type switching in the trigger condition may mean that the type of the network in which the execution main body connects to the internet is changed.
Here, the lifetime may be a persistence time of the domain name resolution record in the domain name resolution server. When domain name resolution servers in various places receive resolution requests, the resolution requests are sent to authoritative domain name servers appointed by domain names, and resolution records are obtained; after obtaining the record, the record will be stored in the domain name resolution server (cache servers in various places, also called recursive domain name servers) for a period of time, and if receiving the resolution request of the domain name again in the period of time, the domain name resolution server will not send the request to the authoritative domain name server any more, but directly return to the record obtained just before; and the time that this record remains on the domain name resolution server is the time-to-live value. It is to be understood that the expiration of the time-to-live value in the above-mentioned trigger condition may refer to the expiration of a domain name record retention time (validity time) in the domain name resolution server.
In this embodiment, the electronic device to which the domain name resolution request is sent may be an electronic device with a domain name resolution function. As an example, the electronic device to which the domain name resolution request is sent may be a Local domain name resolution Server (Local DNS Server) and a network domain name resolution Server.
Here, the local domain name resolution server is generally a domain name resolution server that performs local default setting as described above, for example, a domain name resolution server of a communication operator. The network domain name resolution server described above is generally an authoritative domain name resolution server that provides authoritative resolution. It should be noted that, regarding the authoritative domain name resolution server, the settings of the domain name resolution servers at different levels in the domain name resolution system may be referred to, and details are not described herein.
In this embodiment, an execution subject (for example, a server shown in fig. 1) of the live method may be.
In this embodiment, an executing subject of the domain name resolution method (for example, the terminal device shown in fig. 1) may generate the set of internet protocol addresses based on the internet protocol address returned by the domain name resolution request and indicating the edge node of the content distribution network.
In this embodiment, the internet protocol address returned based on the domain name resolution request may be an electronic device with a domain name resolution function. As an example, the electronic device to which the domain name resolution request is sent may be a network domain name resolution server and/or a local domain name resolution server.
In this embodiment, the ip address received by the execution agent may indicate an edge node of the content distribution network (a content distribution network in which data of a website indicated by the domain name is stored).
As an example, the execution subject may use the forgotten protocol address returned based on the domain name resolution request as the internet protocol address set.
In response to generating the pull request, an ip address is selected from the ip address set, step 403.
In this embodiment, the execution body selects an ip address from the ip address set in response to generating the pull request.
In this embodiment, the execution agent may send a pull request by using the ip address selected in step 403.
The specific operations of step 402 and step 403 in this embodiment are substantially the same as the operations of step 201 and step 202 in the embodiment shown in fig. 2, and are not described again here.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the live broadcasting method in the present embodiment highlights steps related to domain name resolution. Therefore, the scheme described by the embodiment can provide a more comprehensive live broadcast method.
In some optional implementations of this embodiment, the step 402 may be implemented by the step 402 shown in fig. 5, and the step 402 may include:
In this embodiment, an executing entity (for example, the server shown in fig. 1) of the domain name resolution method may determine an internet protocol address corresponding to the domain name from internet protocol addresses returned based on the domain name resolution request.
Optionally, the execution main body may send a first domain name resolution request including the domain name to a network domain name resolution server.
Optionally, the execution main body may send a second domain name resolution request including the domain name to a local domain name resolution server.
Optionally, the executing entity may determine, in response to receiving a first ip address returned by the dns server, the first ip address as an ip address corresponding to the domain name; and in response to not receiving the first internet protocol address returned by the network domain name resolution server, determining a second internet protocol address returned by the local domain name resolution server as the internet protocol address corresponding to the domain name.
In this embodiment, the execution body may select an ip address from the determined ip addresses corresponding to the domain name to obtain the ip address set.
In this embodiment, the ip address set may be obtained by selecting an ip address from the ip addresses corresponding to the determined domain name in various manners.
In some optional implementation manners of this embodiment, the execution main body may set a selection policy by itself, and select an ip address from ip addresses corresponding to the determined domain name to obtain the ip address set.
In some optional implementations of this embodiment, the execution subject may request the other electronic device to evaluate each of the internet protocol addresses corresponding to the determined domain name, and request the other electronic device to return the internet protocol address indicating the good edge node.
In some optional implementations of this embodiment, the method shown in this embodiment may further include: responding to the pull flow generation request, and selecting an internet protocol address from the internet protocol addresses returned by the node evaluation equipment; and sending the pull stream request by using the selected internet protocol address.
In some optional implementations of this embodiment, the method shown in this embodiment may further include: the execution main body sends a test request to the edge node according to the determined internet protocol address corresponding to the domain name; and generating a test result according to the request result of the test request returned by the edge node.
Here, the test request may be a request for testing a communication function of the edge node.
As an example, the test request may include an Internet Packet explorer (PING) request. The principle of PING request is roughly as follows: the execution body sends a data packet to the equipment indicated by the target internet protocol address, and then requires the other party to return a data packet with the same size to determine whether the two network machines are connected and communicated or not and what the time delay is.
In this embodiment, the execution body may generate the test result of each edge node according to the request result of the test request returned by each edge node.
As an example, the request result returned by the edge node may include a data packet returned by the edge node based on the PING request.
The execution body can compare the request result returned by the edge node with the data packet sent by the PING request, and calculate the packet loss rate of the PING request. The execution agent may compare a time when the request result is received with a time when the test request is transmitted, and calculate a time delay value of the PING request.
Optionally, the execution main body may package the packet loss rate and the time delay value into a test result, and send the test result to the node evaluation device.
Optionally, the executing entity may further pack another parameter based on the packet loss rate and the time delay value, and send the result to the node averaging device as a test result. Here, the above-mentioned other parameters may include, but are not limited to, at least one of: a time-to-live value of the acquired internet protocol address and source information (e.g., a local domain name resolution server or a network domain name resolution server) of the acquired internet protocol address.
As an example, the execution body acquires an internet protocol address F, an internet protocol address G, and an internet protocol address H. The execution body may send a test request F to the edge node F indicated by the ip address F, receive a request result F, and generate a test result F. The execution agent may send a test request G G to the edge node G indicated by the ip address G, receive a request result G, and generate a test result G. The execution body can send a test request H to the edge node H indicated by the IP address H, receive the request result H and generate a test result H.
In some optional implementations of this embodiment, step 4022 in this embodiment may include: the execution main body selects an internet protocol address from the determined internet protocol addresses corresponding to the domain name according to the generated test result to obtain the internet protocol address set.
In some optional implementations of this embodiment, step 4022 in this embodiment may include: sending a node evaluation request to a node evaluation device, wherein the node evaluation request includes the determined internet protocol address corresponding to the domain name, and the node evaluation device selects and returns the internet protocol address from the determined internet protocol address corresponding to the domain name according to edge node ranking information for edge nodes in the content distribution network; and determining the internet protocol address returned by the node evaluation equipment as the internet protocol address set.
Optionally, the edge node ranking information is generated in advance by the node evaluation device, and the node evaluation device determines, from the edge node ranking information, ranking information corresponding to each determined internet protocol address corresponding to the domain name, and selects a predetermined number of internet protocol addresses according to each determined ranking information.
As an example, the execution body may send a node evaluation request a to the node evaluation apparatus, the node evaluation request a including an internet protocol address a, an internet protocol address B, and an internet protocol address C. The above-described node evaluation device may determine edge node ranking information in advance, and may include, for example, an internet protocol address a (corresponding to a ranking name of 5), an internet protocol address B (corresponding to a ranking name of 4), an internet protocol address C (corresponding to a ranking name of 3), an internet protocol address D (corresponding to a ranking name of 2), and an internet protocol address E (corresponding to a ranking name of 1). The node evaluation device may find that the internet protocol address a, the internet protocol address B, and the internet protocol address C included in the node evaluation request a are arranged in the order of the ranking nouns in the edge node ranking information from high to low as the internet protocol address C, the internet protocol address B, and the internet protocol address a. The node evaluation device may select the ip address C if it is predetermined that an ip address is to be selected. The node evaluation device may select the ip address C and the ip address B if it is predetermined that two ip addresses are to be selected.
Optionally, the method shown in this embodiment may further include: and sending the generated test result to the node evaluation equipment. As an example, the execution subject may send the test result F, the test result H, and the test result G to the node evaluation device.
Optionally, the edge node ranking information may be generated in real time by the node evaluation device. The node evaluation equipment receives a test result sent by a client; and sequencing at least two edge nodes in the content distribution network according to the received test result, and generating edge node sequencing information aiming at the at least two edge nodes. Then, the node evaluation device may select a predetermined number of internet protocol addresses with a higher ranking, and return the selected internet protocol addresses to the execution main body.
Optionally, the node evaluation device may analyze each received test result by using some preset conditions, so as to implement sorting of the at least two edge nodes. As an example, three parameters, namely a parameter a, a parameter B and a parameter C, may be included in the test result. The preset conditions may include: firstly, comparing a parameter value A corresponding to the parameter A, and forward ranking a test result with a larger parameter value A; if the parameter values A are the same, comparing the parameter values B corresponding to the parameter values B, and forward ranking the test results with larger parameter values B; and if the parameter values B are the same, comparing the parameter values C corresponding to the parameter values C, and forward ranking the test results with larger parameter values C. Therefore, the test result ranking information can be obtained, and then, the order of the test results can be used as the order of the edge nodes (it can be understood that the edge nodes have a corresponding relationship with the test results), so that the edge node ranking information can be obtained.
Optionally, the node evaluation device may score at least two edge nodes in the content distribution network according to the received test result; and generating edge node sequencing information aiming at least two edge nodes according to the grading result.
Optionally, the edge node evaluation device may preset logic that generates the edge node ranking information according to a plurality of test results. For example, weights may be preset for various parameters in the test results, the parameters in each test result are weighted and summed to obtain a score corresponding to the test result, and the score corresponding to the test result is used as the score of the edge node. And sequencing the edge nodes according to the scores of the edge nodes to generate edge node ranking information.
As an example, the edge node evaluation device receives the test result F, the test result H, and the test result G. The edge node evaluation device may perform weighted summation on a plurality of parameters in the test result F to obtain a score F (for example, 70 scores) corresponding to the test result F, and use the score F as the score of the edge node F. The edge node evaluation device may perform weighted summation on a plurality of parameters in the test result H to obtain a score H (for example, 80 scores) corresponding to the test result H, and use the score H as the score of the edge node H. The edge node evaluation device may perform weighted summation on the plurality of parameters in the test result G to obtain a score G (e.g., 90 scores) corresponding to the test result G, and use the score G as the score of the edge node G. Thereby, the edge node ranking information is obtained in order of the internet protocol address G (corresponding ranking name is 1), the internet protocol address H (corresponding ranking name is 2), and the internet protocol address F (corresponding ranking name is 3).
