It will be appreciated that the architecture shown in fig. 1 is merely illustrative and that the signaling server 10 may also include more or fewer components than shown in fig. 1, or have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof. In addition, in order to implement data communication between the client and the client, in this embodiment, the signaling server 10 may further be capable of communicating with the client and a preset streaming server in the session system, so that when a new client joins the current session, a streaming server meeting requirements may be selected from a plurality of streaming servers preset in the session system as an access node to implement data communication between the clients, where the preset streaming servers may be streaming servers related to the current session, may also be preset streaming servers in the session system but not belonging to the current session, and may also be all streaming servers included in the session system, and the like, which is not limited herein.

Further, please refer to fig. 2 in combination, an embodiment of the present invention further provides a data communication method applicable to the signaling server 10. It should be noted that the data communication method of the present invention is not limited by the specific sequence shown in fig. 2 and described below. It should be understood that the order of some steps in the data communication method according to the present invention may be interchanged according to actual needs, or some steps may be omitted or deleted.
Step S11, when receiving a session request for joining the first client to the current session, acquiring a first network parameter between the first client and each streaming media server;
step S12, obtaining a second network parameter when data communication is realized between each streaming media server in the session system and other streaming media servers except the streaming media server;
step S13, selecting a streaming media server meeting a first preset condition as a target server according to the first network parameter and the second network parameter;
step S14, notifying the first client to add the target server as an access node to the current session;
compared with the prior art, in the data communication method provided in the above steps S11-S14, when a new client (first client) received by the signaling server 10 joins the session request of the current session, the streaming media server with the best performance can be selected as the access node according to the network parameters (such as the first network parameters) when the client and each streaming media server in the session system realize data communication and the network parameters (such as the second network parameters) when each streaming media server in the session system and other streaming media servers realize data communication, and the client is notified to join the current session based on the access node, so as to ensure the reliability of the data communication link formed between the client and the streaming media server in the current session, and greatly improve the network communication quality, especially the multimedia communication such as audio and video, to adapt to complex network environments. It should be noted that the current session refers to a communication unit in which some or all of the clients and the streaming media server involved in the session system are participating and performing instant communication, and the session system refers to a client and a streaming media server including but not limited to a client and a streaming media server participating in the current session.
In detail, the first network parameter in step S11 and the second network parameter in step S12 may be, but not limited to, a "pin + IP address" manner, and the like, and for example, the first network parameter may be that the first client obtains the IP address of the streaming media server corresponding to the pin + and sends the obtained IP address to the signaling server 10. The first network parameter and the second network parameter in step S12 may be, but not limited to, one or more of a network delay parameter, a link throughput, a link stability, a network status, and a data transmission rate, which is not limited herein. It should be noted that "the first" and "the second" of the first client and the second client in this embodiment are only to distinguish clients in different states, and have no practical meaning, for example, the first client refers to a client that requests to join a current session, and the second client refers to a client that has already participated in the current session.
Please refer to fig. 3, before the signaling server 10 performs step S11, the first client may first obtain an address list storing address information of each streaming media server in the session system from the signaling server 10, and then sequentially detect a first network parameter between itself and each streaming media server (e.g., the streaming media server M1, the streaming media server M2) based on the address information in the address list and send the first network parameter to the signaling server 10 for selecting a target server.
In step S12, the second network parameter may be obtained by actively obtaining from a streaming media server when the signaling server 10 receives a session request for the first client to join the current session, or may be actively reported to the signaling server 10 by each streaming media server according to a preset time interval. Referring to fig. 4, in order to ensure the accuracy of the second network parameter and improve the selection efficiency of the target server in the embodiment, the acquisition of the second network parameter may be detected by each streaming media server (e.g., the streaming media server M1, the streaming media server M2, and the streaming media server M3 shown in fig. 4) at a preset time interval (e.g., 5s, 10s, etc.), and then each detected second network parameter is sent to the signaling server 10 for storage, so as to be used for selecting the target server.
Further, in step S13, the manner of selecting the target server by the signaling server 10 is different according to the difference between the first network parameter and the second network parameter, and in this embodiment, it is considered that in an actual data communication link, the smaller the network delay amount is, the shortest path between the clients communicating with each other can be determined, that is, the better the stability of the communication link between the two clients is, so in this embodiment, the network delay amount can be used as the selection criterion when selecting the target server. Specifically, as shown in fig. 5, when the first network parameter includes a first network delay parameter and the second network parameter includes a second network delay parameter, the step S13 may be implemented by the following step S130 and step S131, which is specifically described below.
Step S130, aiming at each streaming media server in the session system, respectively calculating the sum of network delay amount when the first client realizes data communication with each second client related in the current session based on the streaming media server according to the first network delay parameter and the second network delay parameter;
step S131, selecting a streaming media server meeting a preset requirement from a plurality of streaming media servers included in the session system as a target server according to the calculated sum of the network delay amount.
In detail, in step S130, since there may be one or more second clients involved in the current session, the actual implementation procedure of step S130 may be different according to the number of the second clients.
For example, when the second client is one, assuming that the second client is C2, if there is a request from the first client C1 to join the current session, since there is a streaming server M1 connected to the second client C2 already in the current session, if the data transmission between the first client C1 and the second client C2 is desired to reach the minimum amount of network delay, the signaling server 10 needs to find the shortest path from the first client C1 to the streaming server M1 (or the second client C2) (i.e., the minimum amount of network delay) from a plurality of streaming servers preset in the session system. The actual selection result can be divided into two cases, one is that the first client C1 is directly connected to the streaming server M1, and the other is that the first client C1 reaches the streaming server M1 through the relay of the streaming server M2.
As an embodiment, as shown in fig. 6, assuming that the delay from the first client C1 to the streaming server M1 is 200ms, the delay from the first client C1 to the streaming server M2 is 30ms, and the delay between the streaming server M1 and the streaming server M2 is 50ms, the best path is that the first client C1 connects to the streaming server M2, and then the streaming server M2 connects to the streaming server M1 as the shortest path, i.e. the streaming server M2 can be the target server.
For another example, when there are a plurality of second clients, a sum of network delay amounts when data communication is implemented between the first client and each of the second clients may be calculated according to the first network delay parameter and the second network delay parameter for each preset streaming media server, and the sum is used as the network delay amount corresponding to the streaming media server. As an embodiment, as shown in fig. 7, assuming that there are two second clients, e.g. C2, C3, if there is a first client C1 joining the current session, then for each streaming server, if the streaming server M1, the streaming server M2, and the streaming server M3 respectively calculate a total sum of network delay amounts D1 when the first client C1 realizes data communication with the second client C2 and the second client C3 when the streaming server M1 is used as an access node, a total sum of network delay amounts D2 when the streaming server M2 is used as an access node and data communication is realized with the second client C2 and the second client C3, and a total sum of network delay amounts D3 when the streaming server M3 is used as an access node and data communication is realized with the second client C2 and the second client C3, and assuming that D2 is the smallest, the streaming server corresponding to the total sum of network delay amounts D2 is used as a target server.
Further, in step S131, since each time a new streaming media server is added to the current session (a new streaming media server is started), a certain server resource is consumed, so as to increase the session cost, in this embodiment, in order to make the performance of the session system better, as shown in fig. 8, step S131 may be implemented by following steps S1310 to S1313, which are specifically described below.
Step 1310, selecting a streaming media server with the minimum network delay amount sum from a plurality of streaming media servers included in the session system as a first server to be compared according to the calculated network delay amount sum;
step S1311, determining whether the first server to be compared is the streaming media server involved in the current session, if so, taking the first server to be compared as the target server, otherwise, executing step S1312-step S1313;
step S1312, selecting the streaming media server with the minimum network delay amount sum from the streaming media servers related to the current session according to the calculated network delay amount sum as a second server to be compared;
step 1313, calculating a difference between a sum of network delay amounts corresponding to the first server to be compared and a sum of network delay amounts corresponding to the second server to be compared, and when the difference is greater than a first preset value, taking the first server to be compared as the target server;
in the above steps S1310 to S1313, the streaming server involved in the current session refers to a streaming server that is already participating in the session and is capable of data communication with the second client involved in the current session. The first preset value may be set according to the requirement of the actual communication link, for example, but not limited to, 80ms, 100ms, and the like.
In detail, as an embodiment, the actual implementation process of the above steps S1310 to S1313 may include: if the first preset value is 100ms and there are already 3 streaming media servers in a running state in the current session system, i.e. M1, M2, and M3, then, when the target server selected when the first client requests to join the current session system is exactly one of M1, M2, or M3, the first client can be directly connected to the target server. Otherwise, a new streaming media server M4 may need to be started, and then the streaming media server M4 needs to be used as the first server to be compared, and one of the streaming media servers M1, M2, and M3 involved in the current session with the smallest network delay amount is selected as the second server to be compared, and the sum of the network delay amounts when the first client and the second clients perform data communication based on the first server to be compared and the second server to be compared is compared, when the sum of the network delay amounts corresponding to the first server to be compared is at least 100ms less than the sum of the network delay amounts corresponding to the second server to be compared, the first server to be compared may be used as the target server and connected to the first client, otherwise, the second server to be compared may be used as the target server and connected to the first client.
It can be understood that, when the difference is greater than the first preset value, it may be determined that a new streaming media server is started, rather than being started, although a certain amount of server resources may be consumed, which increases the session cost, the network communication quality may be greatly improved, and the consumption of server resources is worth while the network performance is improved. In addition, in addition to the step S1313, when the difference is not greater than the first preset value, the second server to be compared may be used as the target server to implement data communication between the first client and the second client.
Further, according to actual requirements, before performing the above step S130 to step S131, in order to reduce the complexity of the data communication method and the overhead of the overall server in the session system in the data communication process, the present embodiment may determine the number of streaming media servers involved in the current session, and further select a target server according to the actual number of streaming media servers involved in the current session, where the specific process may include: the signaling server 10 determines whether the number of the streaming media servers involved in the current session reaches a second preset value, and if the number of the streaming media servers in the running state in the session system does not reach the second preset value, executes step S140-step S141 to select a target server; on the contrary, if the number of the streaming media servers involved in the current session reaches the second preset value, as shown in fig. 9, steps S132 to S133 may be executed, which is specifically described as follows.
Step S132, based on each streaming media server involved in the current session, respectively calculating a sum of network delay amounts when data communication between the first client and each second client involved in the current session is realized according to the first network delay parameter and the second network delay parameter;
step S133, selecting a streaming media server meeting a preset requirement from the streaming media servers related to the current session as a target server according to the calculated total network delay amount.
In detail, the second preset value can be flexibly set according to actual requirements, and is adapted to different network conditions and different user groups, for example, the second preset value may be, but is not limited to, 4, 8, and the like. In addition, as an embodiment, the actual implementation process of the above steps S132 to S133 may include: if the second preset value is 4, that is, when there are 4 streaming media servers involved in the current session (e.g., M1, M2, M3, M4), then, when selecting a target server, the target server may be selected directly based on the streaming media servers M1, M2, M3, M4, or based on each streaming media server preset in the session system, when the selected streaming media server meeting the requirement is not the streaming media server M1, M2, M3, M4 involved in the current session, if the streaming media server meeting the requirement is M5, it may be determined whether M5 can be the target server based on steps S1310-S1313, if so, one of the streaming media servers M1, M2, M3, M4 in a running state may be replaced with M5, and if not, one of the streaming media servers M1, M2 may be directly selected from the streaming media servers M1, M2, And selecting one of the M3 and the M4 with the minimum network delay amount as a target server.
It should be noted that, when the signaling server 10 receives a session request for a first client to join in a current session, if a second client is not involved in the current session, a streaming media server meeting a second preset condition may be directly selected from multiple streaming media servers included in a session system according to the first network parameter as a target server, and the target server is joined in the session system, and a communication connection between the first client and the target server is established.
As an implementation manner, when there is no second client in the current session, it may be determined that the first client is the first client joining the current session, and therefore, the signaling server 10 only needs to select, according to the first network parameter sent by the first client, a streaming media server meeting a first preset condition from streaming media servers preset in the session system as a target server, for example, assuming that the first network parameter is a network delay parameter, the streaming media server with the smallest network delay amount may be selected as an access node to be connected with the first client, so as to join the current session.
It should be noted that, in the data communication method, in order to further improve the selection efficiency of the target server and reduce the complexity of the selection process, in this embodiment, it may further be determined whether there is a server with a downtime, a fault, or a network delay exceeding a preset value in each streaming media server preset in the session system according to the first network parameter and the second network parameter, and if there is a server, the server may be removed from a preset streaming media server list, so that the server may not participate in the election of the target server.
Compared with the prior art, the data communication method provided by the embodiment of the invention also has the following advantages.
(1) Compared with the existing peer-to-peer (P2P) communication mode, the data communication among the clients is realized based on the streaming media server, the stability of the communication network can be effectively ensured, and particularly in a session scene with participation of multiple clients, if the clients need to send multiple data, the data communication mode provided by the invention can greatly reduce the performance pressure and bandwidth consumption of the clients.
(2) Compared with the existing single server mode, the invention adopts a plurality of columns of servers as access nodes to realize data communication between the clients, thereby avoiding the problem that the single server mode cannot ensure the data communication quality of the audio and video due to poor link stability between the clients and the streaming media server in the conversation scene of cross-country regions and cross-operators.
Further, based on the description of the data communication method applied to the signaling server 10, as shown in fig. 10, the present embodiment also provides a data communication method applied to the client, and the data communication method includes the following steps S21-S23, which are specifically as follows.

step S23, sending the first network parameter to the signaling server 10, so that the signaling server 10 selects a streaming media server meeting a second preset condition as a target server communicating with the client according to the first network parameter.
It is to be understood that, since the data communication method given in the above step S21-step S23 has the same or corresponding technical features as the data communication method given in the above step S11-step S14, the detailed description about the above step S21-step S23 may refer to the detailed description about the above step S11-step S14, and the detailed description of the embodiment is omitted here.
