Description

Technical Field

[0001] Embodiments of the present disclosure relate to data communication technologies, and in particular, to a signaling negotiation, data communication method, apparatus, electronic device, and storage medium. Background Art

[0002] In a network service scenario, in the face of a large number of concurrent user accesses, since the processing capacity of a single server is limited, it is difficult to withstand a large number of concurrent requests. Generally, load balancing is used to distribute concurrent requests to multiple servers for processing. The redirection technology is one of the common solutions for implementing load balancing, and it is a technology in which a certain server redirects a data acquisition request of a client to another server.

[0003] In related technologies, generally, the redirection of data requests is implemented based on the redirection function of the HyperText Transfer Protocol (HTTP). That is, through the status code and response header of the HTTP response, the HTTP request is redirected from the current request network address to another network address.

[0004] However, using HTTP redirection requires two signaling negotiation processes, which increases the time for data acquisition. Moreover, in some network service scenarios, such as ultra-low latency live broadcasts, there are often no standard specifications for the signaling negotiation protocol. When using other protocols other than HTTP, since the redirection function of HTTP cannot be used, the response time for data requests may be long or even the response may fail.

[0048] Figure 1 FIG. is a schematic flowchart of a signaling negotiation method provided by an embodiment of the present disclosure. The embodiment of the present disclosure is applicable to the situation of redirecting a signaling request in the signaling phase, and is particularly applicable to a distributed system under a load balancing mechanism. This method can be executed by a signaling negotiation device, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device. Optionally, it can be implemented by an electronic device. The electronic device can be a signaling negotiation server or an upper-layer management device of the signaling negotiation server, etc. The signaling negotiation server can be understood as a server that responds to a signaling request in the signaling negotiation phase of data communication.

[0049] As Figure 1 shown, the method of this embodiment may specifically include:

[0050] S110. In response to a signaling request sent by a client, generate a signaling context corresponding to the signaling request and store the signaling context.

[0051] The client can be understood as the initiating end of the signaling request. Specifically, the client can be an application program corresponding to the server, having a data communication function and providing local services for users. The signaling request can be a data communication request initiated based on a service in the client, such as a live stream pulling signaling request initiated based on a live client.

[0052] The signaling context can be understood as context information for obtaining target data corresponding to the signaling request. Exemplarily, the signaling context may include verification information and data information. The verification information is used for verification in the connectivity detection phase, and specifically may include the negotiation address information of the signaling negotiation server. The data information can be understood as information associated with the target data to be obtained. For example, the data information may include at least one of information such as data format, data version, and data acquisition path.

[0053] Specifically, the client can generate a signaling request based on the received communication trigger operation. Then, the signaling request is sent to the server. The server can allocate a server for the signaling request, that is, determine the signaling negotiation server, and then send the signaling request to the signaling negotiation server. After receiving the signaling request sent by the client, the signaling negotiation server generates a signaling context corresponding to the signaling request. Among them, generating a signaling context corresponding to the signaling request includes, but is not limited to, obtaining the data formats supported by the client and the server and determining the data format in the signaling context. Specifically, the data formats supported by both the client and the server can be used as the data format in the signaling context. After generating the signaling context, the signaling context is stored in the local storage space of the signaling negotiation server for use in the subsequent data stage to obtain the target data corresponding to the signaling request.

[0054] S120. In the case of receiving the redirection address information of the redirection server corresponding to the signaling request, generate a target signaling response message based on the redirection address information and the negotiation address information of the signaling negotiation server.

[0055] Among them, the redirection address information can be understood as the information used to indicate the Internet protocol address of the redirection server. The redirection address information can be the virtual Internet protocol address corresponding to the redirection server, or the public Internet protocol address of the redirection server. The negotiation address information of the signaling negotiation server is the public Internet protocol address of the signaling negotiation server, or the virtual Internet protocol address and the internal network Internet protocol address corresponding to the signaling negotiation server.

[0056] Optionally, generate a target signaling response message based on the original redirection address information and the original negotiation address information of the signaling negotiation server; or, process the redirection address information and the negotiation address information of the signaling negotiation server respectively, and generate a target signaling response message based on the processed redirection address information and negotiation address information.

[0057] In the embodiments of the present disclosure, after receiving a signaling request, it may first be determined whether redirection is required. If redirection is required, the redirection address information of the redirection server corresponding to the signaling request is determined. As an alternative implementation manner of the embodiments of the present disclosure, specifically, after the signaling negotiation server receives the signaling request, it asks the scheduling system of the server side whether redirection is required. The scheduling system determines whether redirection is required based on mechanisms such as load balancing. If it is determined that redirection is required, it will match the redirection server, obtain the redirection address information of the redirection server, and feedback the redirection information to the signaling negotiation server. After receiving the redirection address information of the redirection server fed back by the scheduling system, a target signaling response message is generated based on the redirection address information and the negotiation address information of the signaling negotiation server.

[0058] After receiving the signaling request, a target signaling response message corresponding to the signaling request needs to be generated to inform the server side of the signaling negotiation result. Different from the related art where only the negotiation address information corresponding to the signaling negotiation server is added to the target signaling response message, the target signaling response message in the embodiments of the present disclosure includes both the redirection address information and the negotiation address information of the signaling negotiation server. The redirection address information can be used to establish a connection with the redirection server in the subsequent data phase. The negotiation address information of the signaling negotiation server can provide data support for the redirection server to obtain the signaling context to ensure the smooth progress of data communication.

[0059] S130. Feed back the target signaling response message to the client so that the client performs a connectivity detection based on the redirection address information and obtains target data corresponding to the signaling request based on the detection result.

[0060] Optionally, the signaling negotiation server may directly feed back the target signaling response message to the client; or, the signaling negotiation server directly feeds back the target signaling response message to the client through a proxy server (such as a server deployed with a four-layer load balancing mechanism).

[0061] Specifically, after receiving the target signaling response message, the client can enter the data phase. A connectivity detection request is initiated based on the redirection address information in the target signaling response message. Further, in the case of receiving a detection response message corresponding to the connectivity detection request, it is determined that the communication channel between the client and the server is successfully established, and then data communication can be performed with the server to obtain target data corresponding to the signaling request from the server.

[0062] The technical solution of the embodiment of the present disclosure is as follows. First, in response to a signaling request sent by a client, a signaling context corresponding to the signaling request is generated and the signaling context is stored to determine feedback data corresponding to the signaling request through the signaling context. Then, when receiving the redirection address information of the redirection server corresponding to the signaling request, a target signaling response message is generated based on the redirection address information and the negotiation address information of the signaling negotiation server, and the target signaling response message is fed back to the client, so that the client performs connectivity detection based on the redirection address information and obtains target data corresponding to the signaling request based on the detection result. It is possible to obtain both the redirection address information and the negotiation address information in one signaling request, so that a connection can be established between the redirection server and the client based on the redirection address information and the negotiation address information in the data stage. That is, it is possible to establish a connection with the redirection server in one signaling request, solving the technical problems in the related art that rely on a specific protocol to implement the redirection function and the reduction of the request-response efficiency due to redirection, and being able to adapt to multiple network protocols, overcoming the dependence on a specific protocol for redirection, achieving the effects of expanding the application scenario of redirection and reducing the signaling interaction time in the redirection scenario.

[0063] Figure 2 The flow diagram of another signaling negotiation method provided by the embodiment of the present disclosure. On the basis of the above embodiment, the technical solution of this embodiment further refines the generation process of the signaling response message. Optionally, generating a target signaling response message based on the redirection address information and the negotiation address information of the signaling negotiation server includes: creating an initial signaling response message corresponding to the signaling request; respectively determining first address filling information corresponding to the redirection address information and second address filling information corresponding to the negotiation address information of the signaling negotiation server; generating target address filling information based on the first address filling information and the second address filling information, and filling the target address filling information into the initial signaling response message to obtain the target signaling response message. The specific implementation can refer to the description of this embodiment. Among them, the same or similar technical features as those in the foregoing embodiment will not be described in detail here.

[0064] As Figure 2 shown, the method of this embodiment may specifically include:

[0065] S210. In response to a signaling request sent by a client, generate a signaling context corresponding to the signaling request and store the signaling context.

[0066] S220. When receiving the redirection address information of the redirection server corresponding to the signaling request, create an initial signaling response message corresponding to the signaling request.

[0067] Among them, the initial signaling response message can be understood as a model of the pre-constructed signaling response message. The initial signaling response message includes a candidate address and verification information. Generally, the parameter values corresponding to the candidate address and verification information in the initial signaling response message are the initial parameters set by the template or are empty, to be filled in after being determined by the server.

[0068] It can be understood that the specific format and content of the initial signaling response message are related to the technology adopted for signaling negotiation, and the specific format and content thereof are not limited herein.

[0069] S230. Determine the first address filling information corresponding to the redirection address information and the second address filling information corresponding to the negotiation address information of the signaling negotiation server respectively.

[0070] Among them, the first address filling information can be understood as the information used to indicate the redirection address information to be written into the initial signaling response message.

[0071] As an optional implementation manner of the embodiments of the present disclosure, the redirection address information can be used as the first address filling information corresponding to the redirection address information. This technical solution is applicable to the situation where the network environment is relatively secure. The advantage of directly using the redirection address information as the first address filling information is that there is no need to perform secondary processing on the redirection address information, which is beneficial to quickly generating the target signaling response message based on the initial signaling response message.

[0072] Considering that in the process of information transmission, there may be risks of being maliciously attacked or maliciously applied after information leakage. As another optional implementation manner of the embodiments of the present disclosure, the redirection address information can be encrypted to obtain the first address filling information. By adopting this technical solution, the redirection address information can be converted into encrypted information, which can reduce the risk of directly applying the redirection address information after it is intercepted, and improve the information security of the redirection address information.

[0073] In the embodiments of the present disclosure, there can be various ways to encrypt the redirection address information. Optionally, the redirection address information is encrypted based on a preset encryption algorithm. Among them, the preset encryption algorithm can be one or more of a symmetric encryption algorithm, an asymmetric encryption algorithm, and a hash encryption algorithm. Which specific encryption algorithm is adopted to encrypt the redirection address information can be set according to actual needs, and the specific algorithm adopted is not limited herein.

[0074] To avoid the risk of decrypting the encrypted information of the redirect address information through a decryption algorithm to obtain the redirect address information, the redirect address information may not be added as the first address filling information in the initial response message. For example, other information that has a mapping relationship with the redirect address information may be used as the first address filling information. As another alternative implementation manner of the embodiments of the present disclosure, the first address identification information corresponding to the redirect address information is determined, and the first address identification information is used as the first address filling information. By adopting this technical solution, the first address identification information can be used to replace the redirect address information, avoiding the risk of intercepting the target response message to parse out the redirect address information, fully ensuring the information security of the redirect address information, and thus ensuring the information security of the redirect server.

[0075] Optionally, determining the first address identification information corresponding to the redirect address information includes: obtaining the pre-set first address identification information corresponding to the redirect address information; or converting the redirect address information into the first address identification information based on a pre-set identification conversion interface.

[0076] Optionally, address identification information is pre-set for the server address information of each server, and a corresponding relationship is established between the server address information and the address identification information. Further, based on this corresponding relationship, the address identification information corresponding to the redirect address information is queried as the first address identification information. It should be noted that the address identification information may be partial information of the redirect address information or other information different from the redirect address information. Exemplarily, the address identification information may be the server identification corresponding to the server, such as the server number, etc.

[0077] Among them, the identification conversion interface can be understood as a function that converts the input redirect address information into other information according to a pre-set conversion rule. In the embodiments of the present disclosure, the redirect address information can be input into the identification conversion interface, and after being processed by the identification conversion interface, the converted information is output, and the converted information is used as the first address identification information. It can be understood that the conversion rule can be set according to actual needs and is not specifically limited herein.

[0078] Further, the identification conversion interface can also be used to reversely convert the first address identification information into the redirect address information to facilitate reverse parsing of the redirect address information. Or, the first address identification information can be reversely converted into the redirect address information through a pre-set address conversion interface. Optionally, when the address conversion interface is in a valid state, the information added to the first address identification information is filled into the initial response message as the first address filling information. When the address conversion interface is in an invalid state, the encrypted information obtained by encrypting the information added to the redirect address information is filled into the initial response message. The advantage of such a setting is that it can ensure the smooth acquisition of the redirect address information.

[0079] In some application scenarios, the above methods can be combined to determine the first address filling information corresponding to the redirected address information. For example, it is possible to detect whether the identification conversion interface is valid. If it is valid, the identification conversion interface is used to obtain the first address filling information; if it is invalid, the first address filling information is obtained through encryption processing, or the redirected address information is used as the first address filling information. Specifically, when the identification conversion interface is in a valid state, the redirected address information is converted into the first address identification information based on the identification conversion interface, and the first address identification information is used as the first address filling information; when the identification conversion interface is in an invalid state, the redirected address information is encrypted to obtain the first address filling information. By adopting this technical solution, double protection is provided for the information security of the redirected address information, which not only ensures the smooth progress of the signaling negotiation process but also improves the information security of the redirected address information.

[0080] Similarly, determining the second address filling information corresponding to the negotiation address information of the signaling negotiation server may include: encrypting the negotiation address information to obtain the second address filling information; and / or determining the second address identification information corresponding to the negotiation address information and using the second address identification information as the second address filling information.

[0081] Furthermore, determining the second address identification information corresponding to the negotiation address information includes: obtaining the pre-set second address identification information corresponding to the negotiation address information; or converting the negotiation address information into the second address identification information based on a pre-set identification conversion interface.

[0082] On this basis, determining the second address filling information corresponding to the negotiation address information may include: when the identification conversion interface is in a valid state, converting the negotiation address information into the second address identification information based on the identification conversion interface and using the second address identification information as the second address filling information; when the identification conversion interface is in an invalid state, encrypting the negotiation address information to obtain the second address filling information.

[0083] Similarly, the identification conversion interface can also be used to reversely convert the second address identification information into the negotiation address information to facilitate the reverse parsing of the negotiation address information. Or, the first address identification information can be reversely converted into the negotiation address information through a pre-set address conversion interface. Optionally, when the address conversion interface is in a valid state, the added second address identification information is filled into the initial response message as the second address filling information. When the address conversion interface is in an invalid state, the encrypted information obtained by encrypting the added negotiation address information is filled into the initial response message. The advantage of this setting is that it can ensure the smooth acquisition of the negotiation address information.

[0084] It should be noted that the identification conversion interface for converting negotiation address information into second address identification information and the identification conversion interface for converting redirection address information into first address identification information can be the same interface or different interfaces. Similarly, the address conversion interface for converting second address identification information into negotiation address information and the address conversion interface for converting first address identification information into redirection address information can be the same interface or different interfaces.

[0085] S240. Generate target address filling information based on the first address filling information and the second address filling information, and fill the target address filling information into the initial signaling response message to obtain a target signaling response message.

[0086] Among them, the target address filling information is information for indicating redirection address information and negotiation address information to be written into the initial signaling response message.

[0087] Exemplarily, the target address filling information includes candidate address information and target verification information. Specifically, generating target address filling information based on the first address filling information and the second address filling information includes: using the first address filling information as the candidate address information; splicing the second address filling information and the verification association information in a preset order to obtain the target verification information, where the verification association information includes a verification random number, and the verification random number is used to identify the validity of the network communication protocol.

[0088] Optionally, the verification association information may further include connection identification information and / or signaling request protocol type. The connection identification information can be used to distinguish a single signaling request. For example, in the case of receiving a live stream pulling signaling request, the connection identification information is used to distinguish a single live stream pulling. The signaling request protocol type determines whether to use a security protocol when judging the signaling request context. In the embodiments of the present disclosure, the splicing method of the verification information can be set according to actual needs and is not specifically limited herein.

[0089] Taking the data communication scenario implemented based on WebRTC (Web Real-Time Communication) as an example, for instance, the millisecond-level low-latency live broadcast technology implemented based on WebRTC, RTM (Real-time Media, ultra-low-latency live broadcast). WebRTC communication is usually divided into two stages: the signaling stage and the data stage. In the signaling stage, the client and the server exchange signaling information, which is usually described by SDP (Session Description Protocol), including session description and candidate addresses (ICE Candidate), etc. Among them, the candidate address is a combination of the IP address and port number allocated by the server for media transmission. In the data stage, the client first performs ICE (Interactive Connectivity Establishment) connection establishment, detects the candidate address of the server received in the signaling stage to ensure connection to an accessible network, and thus establishes a data transmission channel.

[0090] The signaling negotiation server providing the signaling service saves the context of the signaling negotiation, fills the external network IP / VIP of the redirect server into the candidate address a=candidate line of the initial signaling response message SDP answer returned to the client, and fills the second address identification information of this server or the encrypted external network IP / VIP (Virtual IP Address) and the internal network IP into the verification information a=ice-ufrag line, so as to obtain the target signaling response message.

[0091] Among them, ice-ufrag saves the negotiation address information of the signaling negotiation service, which can be understood as the verification information in the target response message. In the embodiments of the present disclosure, the content of ice-ufrag can be customized. Exemplarily, the first byte of ice-ufrag can be identified by the special character @, and the second byte can be used to identify the version of ufrag. According to the specific content of generating the token in the TLV (Type-Lengh-Value) manner, the token is used as the ice-ufrag of the SDP answer. Optionally, Type occupies 4 bits, Lengh occupies 8 bits, and the 4 bits in the middle of Type and Length are reserved for future further expansion, and a total of 2 bytes are occupied.

[0092] S250: Feed back the target signaling response message to the client, so that the client performs connectivity detection based on the redirect address information and obtains the target data corresponding to the signaling request based on the detection result.

[0093] In the technical solution of the embodiment of the present disclosure, a target signaling response message is generated through the redirected address information and the negotiated address information of the signaling negotiation server, so that the client can not only obtain the information of the redirection server but also obtain the information of the signaling negotiation server. Since the signaling negotiation server stores the signaling context, it provides a basis for the redirection server to obtain the signaling context from the signaling negotiation server. Furthermore, it provides data support for establishing a successful connection between the redirection server and the client in the subsequent connectivity detection of the redirection server during the data stage.

[0094] Figure 3 It is a schematic flowchart of a signaling negotiation method in a data communication scenario implemented based on WebRTC provided by an embodiment of the present disclosure. As Figure 3 shown, the execution process of the signaling negotiation method includes:

[0095] 1. After the signaling negotiation server of the server receives the signaling request (SDP offer) from the client, it performs signaling negotiation and creates an initial signaling response message (SDP answer).

[0096] 2. The scheduling system of the server decides whether to redirect according to the need. If it redirects, the VIP / public network IP of the redirection server is used as the information to be filled in the a=candidate line of the SDP answer to be filled, otherwise, the VIP / public network IP of the signaling negotiation server (local machine) is used as the information to be filled in the a=candidate line of the SDP answer to be filled.

[0097] 3. The server detects whether the address conversion interface for obtaining the public network IP / VIP and the internal network IP of the server according to the second address identification information is valid. If it is valid, the second address identification information of the local machine is filled in the a=ice-ufrag line of the SDP answer, otherwise, the negotiated address information of the local machine, that is, the VIP / public network IP and the internal network IP, is filled in the a=ice-ufrag line of the SDP answer.

[0098] 4. The signaling negotiation server of the server saves the signaling context and sends the filled target signaling response message SDP answer to the client.

[0099] 5. After receiving the SDP answer, the client fills the content of the a=ice-ufrag line into the USERNAME attribute of the connectivity detection request STUN Binding Request), and sends it to the server address specified in the a=candidate line of the target signaling response message for connectivity detection to establish a media channel.

[0100] By adopting this technical solution, redirection can be carried out simply and quickly, and the redirection information can be fed back to the client and applied to subsequent data phases. It does not depend on the HTTP protocol and does not require a secondary request. A media channel can be established in a single signaling request, improving the response efficiency of redirection.

[0101] Figure 4 FIG. 4 is a schematic flow chart of another data communication method provided by an embodiment of the present disclosure. The embodiments of the present disclosure are applicable to the interaction scenario in the data phase after redirecting a signaling request, and are particularly applicable to a distributed system under a load balancing mechanism. This method can be executed by a data communication device, which can be implemented in the form of software and / or hardware. Optionally, it is implemented by an electronic device, which can be a server or an upper management device of the server, etc.

[0102] As Figure 4 shown, the method of this embodiment may specifically include:

[0103] S410. Receive a connectivity detection request sent by the client based on the redirection address information of the redirection server, where the connectivity detection request includes the negotiation address information of the signaling negotiation server, and the signaling negotiation server stores a signaling context corresponding to the signaling request.

[0104] As described above, after receiving the target signaling response message, the client can enter the data phase. Obtain the negotiation address information of the signaling negotiation server in the target signaling response message, generate a connectivity detection request based on this negotiation address information, and initiate a connectivity detection request to the redirection address information in the target signaling response message to send the connectivity detection request to the redirection server.

[0105] S420. In the case where the negotiation address information is inconsistent with the redirection address information, initiate a context acquisition request to the signaling negotiation server based on the negotiation address information to obtain the signaling context from the signaling negotiation server.

[0106] Optionally, the redirection address information includes a first virtual service address corresponding to the redirection server, and the negotiation address information includes a second virtual service address and a first actual service address of the negotiation server. It should be noted that both the first virtual service address and the second virtual service address can correspond to multiple servers, and thus can also correspond to the actual service addresses of multiple servers.

[0107] At this time, when initiating a context acquisition request to the signaling negotiation server based on the negotiation address information, it can first determine whether the first virtual service address is the same as the second virtual service address, and whether the actual physical address of the redirection server is the same as the first actual service address of the negotiation server. If they are the same, that is, the local machine, the signaling context can be directly obtained from the current redirection server.

[0108] Optionally, when the first virtual service address is the same as the second virtual service address, initiate a context acquisition request to the negotiation server based on the first actual service address; receive the signaling context corresponding to the context acquisition request feedback by the negotiation server.

[0109] Optionally, when the first virtual service address is different from the second virtual service address, initiate a context acquisition request to the second virtual service address; receive the signaling context corresponding to the context acquisition request feedback by the response server corresponding to the second virtual service address, where the response server is the server that receives the context acquisition request.

[0110] In practical applications, the response server that receives the context acquisition request may be the signaling negotiation server or may not be the signaling negotiation server. Therefore, the second actual service address of the response server may be the same as or different from the first actual service address. Specifically, when the second actual service address of the response server is the same as the first actual service address, the response server is the signaling negotiation server storing the signaling context, and the signaling context can be directly obtained from the response server. When the second actual service address of the response server is different from the first actual service address, the signaling context is obtained by the response server from the signaling negotiation server based on the first actual service address.

[0111] Specifically, the context request can be sent to the signaling negotiation server based on the first actual service address via the response server, and then receive the signaling context feedback by the signaling negotiation server via the response server.

[0112] For example, after the redirection server (local machine) of the server receives a connectivity detection request (STUN Binding Request), it parses the USRNAME attribute in the STUN packet. If the USERNAME stores the negotiation address information of the signaling negotiation server (e.g., the second address identification information), at this time, it is determined whether the negotiation address information belongs to the local machine. If so, the signaling context is directly obtained from the local machine; if not, the cluster name, public network IP / VIP, and private network IP are obtained through the negotiation address information. If the USERNAME stores the public network IP / VIP and private network IP, the cluster name is parsed through the public network IP / VIP. Then, it is determined whether the obtained cluster name is the cluster where the local machine is located. If it is the cluster where the local machine is located and the private network IP is also the local machine, the signaling context is directly obtained from the local machine. Otherwise, a signaling context is requested from the private network IP. If it is not the cluster where the local machine is located, a signaling context is requested from the VIP / public network IP. The response server that receives the signaling context request rereads the above steps of determining whether the negotiation address information belongs to the local machine and subsequent steps. After obtaining the signaling context, the above process ends, and a data communication channel is normally established to provide data communication services.

[0113] If the number of requests for the context request exceeds a preset number threshold (e.g., 3 times), or the request duration of the context request exceeds a preset duration, it can be considered that an exception has occurred. The current signaling request can be terminated, a request failure prompt message can be generated, and it can be fed back to the client.

[0114] S430. After obtaining the signaling context, a connectivity response message corresponding to the connectivity detection request is generated, and the connectivity response message and the target data corresponding to the signaling request are sent to the client based on the signaling context.

[0115] After the redirection server obtains the signaling context, it can determine the target data requested by the client in the signaling request based on the signaling context. At this time, a connectivity response message corresponding to the connectivity detection request can be generated and sent to the client. When the client receives the detection response message corresponding to the connectivity detection request fed back by the redirection server, it is determined that a communication channel has been successfully established between the client and the server, and data communication with the server can be realized. At this time, the target data can be obtained from the server.

[0116] For the sake of easy understanding, continue to introduce with the data communication scenario implemented based on WebRTC as an example. When the client performs ICE connection establishment, it sends a STUN (Session Traversal Utilities for NAT) Binding Request packet to the redirected candidate address in the SDP received in the signaling phase (i.e., the external network IP / VIP indicated by the redirected address information) for connectivity detection, and the ice-ufrag field of the SDP will be filled into the USERNAME attribute of the STUN packet. After the redirected server that establishes the media channel with the client receives the STUN Binding Request packet, it parses the external network IP / VIP and internal network IP in the USERNAME attribute, locates the server providing the signaling service, and obtains the signaling context of this signaling request through an HTTP request to continue providing the data transmission service, thus realizing the redirection of data communication.

[0117] It should be noted that the signaling negotiation server and the redirected server are not functional limitations on the servers in the cluster, but are used to distinguish the response actions performed by the servers in different stages of data communication. In a signaling request, the server allocated in the signaling negotiation phase for storing the context to respond to the signaling request is called the signaling negotiation server, and the server that establishes a connection in the data phase after redirection is the redirected server. In actual applications, a cluster often receives various signaling requests. The signaling negotiation server and the redirected server are dynamically allocated when responding to signaling requests and may be any server in the cluster. In other words, the same server in the cluster may be the signaling negotiation server in a certain signaling request and the redirected server in another signaling request.

[0118] In the technical solution of the embodiment of the present disclosure, first, by receiving the connectivity detection request sent by the client based on the redirection address information of the redirection server, since the connectivity detection request includes the negotiation address information of the signaling negotiation server, and the signaling negotiation server stores the signaling context corresponding to the signaling request, the connectivity detection request can be sent to the redirection server and can inform the redirection server of the storage address of the signaling context. Then, in the case where the negotiation address information is inconsistent with the redirection address information, a context acquisition request is initiated to the signaling negotiation server based on the negotiation address information to obtain the signaling context from the signaling negotiation server, laying a foundation for the determination of subsequent target data. Finally, after obtaining the signaling context, a connectivity response message corresponding to the connectivity detection request is generated, and the connectivity response message and the target data corresponding to the signaling request are sent to the client based on the signaling context. It is possible to establish a communication channel with the redirection server in the data stage to achieve data communication, realize the redirection of data communication in one request, reduce the signaling interaction time in the redirection scenario, and improve the response efficiency of redirection.

[0119] Figure 5 It is a schematic flowchart of another data communication method provided by the embodiment of the present disclosure. Assume that the signaling negotiation server is server 13 in cluster 1, and the negotiation address information is VIP1 and the internal network IP of server 13. The redirection server is server 21 in cluster 2, and VIP2 is the redirection address information of the redirection server.

[0120] As Figure 5 shown, the client sends the connectivity detection request to server 21 based on VIP2. After receiving the connectivity detection request, server 21 parses out the negotiation address information corresponding to the signaling negotiation server, that is, VIP1 and the internal network IP of server 13. Then, after comparison, it is found that the parsed negotiation address information is VIP1 instead of VIP2, that is, the signaling negotiation server is not in cluster 2. At this time, the redirection server sends a context acquisition request to VIP1. At this time, VIP1 may send the context acquisition request to any server under VIP1. Assume that VIP1 may send the context acquisition request to server 11. At this time, the VIP1 and internal network IP corresponding to server 11 are compared with the negotiation address information, that is, VIP1 and the internal network IP of server 13, and it is found that the signaling negotiation server is not the local machine. At this time, server 11 sends a context acquisition request to slave server 13 according to the internal network IP of server 13. After receiving the signaling context sent by server 13, server 11 feeds it back to server 21 of VIP2.

[0121] After the server 21 obtains the signaling context, it sends a connectivity response message corresponding to the connectivity detection request to the client to establish a communication connection, and can feedback the target data corresponding to the signaling request to the client based on the signaling context.

[0122] The technical solution of the embodiment of the present disclosure realizes signaling sharing between nodes and realizes redirection of data communication without having to re-initiate a signaling request.

[0123] Figure 6 FIG. is a schematic structural diagram of a signaling negotiation device provided by an embodiment of the present disclosure.

[0125] The technical solution of the embodiment of the present disclosure first generates a signaling context corresponding to the signaling request in response to the signaling request sent by the client and stores the signaling context to determine the feedback data corresponding to the signaling request through the signaling context; then, when receiving the redirection address information of the redirection server corresponding to the signaling request, generates a target signaling response message based on the redirection address information and the negotiation address information of the signaling negotiation server, and feedbacks the target signaling response message to the client, so that the client performs a connectivity detection based on the redirection address information and obtains the target data corresponding to the signaling request based on the detection result. It can obtain the redirection address information and the negotiation address information simultaneously in one signaling request, so that a connection can be established between the redirection server and the client based on the redirection address information and the negotiation address information in the data stage, that is, it can establish a connection with the redirection server in one signaling request, solving the technical problems in the related art that rely on a specific protocol to implement the redirection function and the reduction of the request response efficiency due to redirection, being able to adapt to multiple network protocols, overcoming the dependence on a specific protocol for redirection, expanding the application scenarios of redirection, and reducing the signaling interaction time in the redirection scenario.
