In the prior art, a server public network maps each port of a terminal, and establishes a session with the terminal, thereby implementing data transmission. However, the terminal has multiple ports, and the server needs to map all ports of the terminal for the session through the public network, thereby occupying multiple public network port resources. In this case, since the terminals in session with the server are limited by the resources of the public network ports, and each terminal and the server need to occupy multiple resources of the public network ports to establish a session, the server can only perform session connection with a limited number of terminals.
In order to solve the above technical problem, an embodiment of the present application provides a data transmission method, please refer to fig. 1, and fig. 1 is a flowchart of the data transmission method provided in the embodiment of the present application. The data transmission method provided by the embodiment of the application comprises the following steps:

The first server cluster is a routing server cluster and is used for directly sending the first data packets to the target server after receiving the N first data packets sent by the target terminal. In the same session, the first data packets of the terminal are all sent to the target server from the same first server in the first server cluster. The data packets comprise address information of a target terminal and data to be transmitted, the N first data packets are different in type, and N is a positive integer larger than 1.
The address information of the target terminal is Internet Protocol (IP) information.
The N first packets are packets sent from ports of the destination terminal, and the types of the first packets sent by the ports of different destination terminals are different. For example, the first data packet includes video data and audio data of a video conference. It can be understood that the N first data packets are data packets sent by the target terminal, so that the address information of the data packets is the same, and the first server determines that the data packet is from one target terminal according to the address information, and performs the same sending process on the data packets with the same address information, please refer to the following embodiments.
S102, the first server cluster sends the N first data packets to a target port in a target server according to a preset first mapping relation; the first mapping relation is used for representing the mapping relation between the address information of the target terminal and the address information of the target port.
The target server is a conference server and is used for processing a first data packet related to the video conference; the target port is a media port of the conference server and is used for receiving or sending a first data packet related to the video conference. The first mapping relation comprises the mapping relation between the address information of the target terminal and a target port of the target server, and the target port is a port of the target server
In this step, after receiving the first data packet of the target terminal, the first server cluster sends the data packet to the target server according to the first mapping relationship, and completes the data transmission process of sending the data packets of the multiple ports of the target terminal to the target port of the target server. Specifically, after receiving a first data packet with the same address information, a first server cluster queries a preset mapping relationship and determines the first mapping relationship; and determining a target port of the target server according to the first mapping relation, and then sending the received first data packet to the target port of the target server.
It should be understood that in a video conference, one or more terminals establish a session with a target server, and a mapping relationship corresponding to address information of the plurality of terminals is preset in a first server cluster. For example, a first terminal and a second terminal need to establish a session with a target server, and at this time, a first server cluster receives a first data packet of the first terminal and a first data packet of the second terminal, where the first data packet of the first terminal includes address information of the first terminal, and the first data packet of the second terminal includes address information of the second terminal; confirming a target server according to the address information of the first terminal, and confirming the target server according to the address information of the second terminal; and sending the data packet of the first terminal and the data packet of the second terminal to a target port of a target server, and establishing a session between the first terminal and the target server and a session between the second terminal and the target server.
In the embodiment of the application, a first server cluster receives N first data packets sent by a second server cluster; the first server cluster sends N data packets to a target port in a target server based on a first mapping relation, and a session between the first server cluster and the target server is established through the target port, wherein the first mapping relation is used for representing the mapping relation between address information of a target terminal and address information of the target port, so that the first server cluster can establish the session between the first server cluster and the target server by calling the target port in the target server, occupation of port resources is reduced, and the port resources are released.
Optionally, the sending, by the first server cluster, the N first data packets to the target port in the target server according to the preset first mapping relationship includes:
the first server cluster performs hash operation on the address information of the target terminal included in the N first data packets to obtain a first hash value;
the first server cluster sends the N first data packets to a target port in a target server according to a preset first mapping relation under the condition that the first hash value is the same as the second hash value;
the second hash value is determined by performing hash operation on address information of the target terminal included in a second data packet, where the second data packet is a data packet that is sent by the second server cluster to the first server cluster for the first time.
In this embodiment, the second server cluster sends the second data packet of the target terminal to the first server cluster, so that the first server cluster determines the second hash value after receiving the second data packet; after receiving the first data packet, the first server cluster determines a first hash value according to address information of the first data packet, compares the first hash value with a second hash value, determines whether the first data packet is sent by a target terminal, and sends N first data packets to the target server according to a first mapping relation under the condition that the first hash value is the same as the second hash value. Therefore, the first server cluster sends the second data packet to the second server cluster, so that the first data packet of the target terminal received by the first server cluster is always sent by the same second server in the second server cluster in the same session, the streaming data is transmitted through the same intermediate node, and the source address received by the target server is ensured not to change in the complete session process.
It should be understood that the second Server cluster is a Load Balancing (SLB) Server cluster, and is configured to be distributed to a plurality of Load servers for execution after receiving the data packet sent by the target terminal. In order to ensure that the source address received by the target server does not change in the same session, the second server cluster sends the data packet of the target terminal to the first server cluster through the same load server.
For example, please refer to fig. 2, fig. 2 is a schematic diagram illustrating that a terminal sends a data packet to a target server according to an embodiment of the present application. In fig. 2, after receiving the packet transmitted by the destination terminal 201, the second server cluster 202 allocates the packet according to the history transmission information, and allocates the packet to the load server L1. The load server L1 sends the data packet to the routing server R1 of the first server cluster 203 according to the history sending information, and the routing server R1 sends the data packet of the target terminal 201 to the server S1 in the target server 204.
Optionally, the first server cluster includes M first servers, the first server cluster establishes an association relationship between the M first servers based on a hash ring, the hash ring is determined based on address information corresponding to the M first servers, and M is a positive integer greater than 1;
the hash ring is used for determining a first target server, the first target server is one server in the first server cluster, and the first target server is used for receiving N first data packets sent by the second server cluster.
The hash ring is a virtual ring node, and the second server cluster determines the first target server according to the hash ring. Illustratively, as shown in fig. 3, M nodes are provided on the hash ring, and each node corresponds to one first server. Wherein the range of hash values is represented between each node. For example, there are 3 nodes on the hash ring, node R1, node R2 and node R3, the range of hash values represented between node R1 and node R2 is [0,100], the range of hash values represented between node R2 and node R3 is [100,200], and the range of hash values represented between node R3 and node R1 is [200,300]. And determining the first target server through the hash ring and the hash value determined by the second server cluster, which is described in the subsequent embodiments.
In this embodiment, the first target server is determined by the hash ring and the hash value determined by the second server cluster, and then the first target server continuously receives N first data packets sent by the second server cluster, thereby implementing the fixation of the intermediate transmission stage.
Optionally, the first server cluster establishes an association relationship between the N first servers based on a hash ring and P virtual servers, a virtual server is arranged between the first servers having an adjacent relationship on the hash ring, address information of the virtual server is the same as address information of the corresponding first server, and P is a positive integer greater than 1;
the hash ring and the P virtual servers are used to determine the first target server.
The M first servers establish an association relation based on the hash ring, and under the condition that the second server cluster determines the first target server, a certain node has more accesses in a concentrated mode, so that the virtual server is introduced based on the condition for reducing the access amount of a single node.
Illustratively, as shown in fig. 4, three first servers establish association based on hash rings, and two virtual servers are added between each first server. The address information of the virtual server is the same as that of the first server, so that the second server cluster sends the N first data packets to the first server after determining the virtual server.
For example, the hash value range between node R1-1 and node R2-1 is [0,33], the hash value range between node R2-1 and node R3-1 is [34,67], and the hash value range between node R3-1 and node R1-2 is [68,100]. Wherein the range between the node R1-1 and the node R1-2 is still [0,100], corresponding to the ranges between the node R1-1 and the node R2-1, the node R2-1 and the node R3-1, and the node R3-1 and the node R1-2. The address information corresponding to the node R1-1, the node R2-1 and the node R3-1 is address information which is address information of the first server R1, wherein the node R1-1 and the node R2-1 are virtual server nodes. And under the condition that the determined hash ring positions are the node R1-1, the node R2-1 and the node R3-1, determining that the first target server is the first server R1, as shown in FIG. 5.
In this embodiment, the virtual server is added to the hash ring, so that the access amount of a single node is reduced, and the load of the first server cluster is balanced.
Optionally, before the first server cluster receives N first data packets sent by the second server cluster, the method further includes:

and the first server cluster establishes the first mapping relation based on the address information of the target terminal and the address information of the target port.
In this embodiment, the first mapping relationship includes address information of the target terminal and a mapping relationship between the target terminal and the target server, and in data transmission of the video conference, the target terminal does not always perform data transmission with the target server, and different terminals have mapping relationships with different servers in different sessions. In this embodiment, a first mapping relationship is established before the first server cluster receives N first data packets sent by the target terminal, so that the target terminal and the target server establish a session.
The second data packet is a data packet sent by the target terminal to a target port of the target server, and the third data packet is a data packet sent by the target server to address information of the target terminal. Before the second data packet is sent to the target port of the target server by the target terminal, the target terminal needs to receive the information of the target port of the target server. Similarly, the destination server needs to receive the address information of the destination terminal before sending the third packet to the address information of the destination terminal. The process is as follows:
referring to fig. 6, fig. 6 is a schematic diagram illustrating establishment of a first mapping relationship according to an embodiment of the present application. Before the target terminal 201 and the target server 204 establish a session, registration is required to be performed by the messenger server 301 in fig. 6, respectively, the target terminal 201 transmits address information to the messenger server 301, the target server 204 transmits information of a target port to the messenger server 301, and the messenger server 301 stores the address information and the information of the target port. When the target terminal 201 and the target server 204 establish a session, the messenger server 301 transmits information of the target port of the target server 204 to the target terminal 201, and transmits address information of the target terminal 201 to the target server 204.
Further, the first server cluster 203 receives the address information of the second data packet of the target terminal 201 and the address information of the third data packet of the target server 204, and establishes the first mapping relationship.
Optionally, the N data packets include:
the audio data package of the first protocol, the audio data package of the second protocol, the video data package of the first protocol, the video data package of the second protocol.
It should be understood that the data transmission of the video conference includes audio data and video data, the data transmission being performed by the first protocol and the second protocol, respectively. The first Protocol is Real-Time Transport Protocol (RTP), and the second Protocol is RTCP. In a target terminal, sending data packets of different protocols by adopting different interfaces; in the target server, one media interface is adopted to receive all the data packets, and port multiplexing is realized, so that occupation of sessions on public network port resources is reduced, and the number of terminals which can be connected with the target server is increased.
Illustratively, the third data packet includes a message sent by the target terminal 201 to the target server 204, as shown in table one:
The specific process is that the target terminal 201 sends the third data packet to the second server cluster 202, the second server cluster 202 sends the third data packet to the first server cluster 203, and finally the first server cluster 203 sends the third data packet to the target server 204.
It should be understood that the process of the target terminal 201 sending the third data packet to the second server cluster 202 is an extranet transmission process, and the process of the first server cluster 203 sending the third data packet to the target server 204 is an intranet transmission process. When the target terminal 201 sends the third data packet to the second server cluster 202, the third data packet is sent to the public network address of the target Port of the target server, that is, the Port-a in table one; after receiving the third data packet, the second server cluster 202 sends the third data packet to the first server cluster 203; in the internal transmission process, the target port of the target server needs to be converted from the public network address to the internal network address, as shown in the following table two:
watch two
According to the above table, after the first server cluster 203 receives the third data packet, the public network address of the third data packet is converted from IP2 to IP3, the public network Port is converted from Port-a to Port-a, port-b, port-c and Port-d, the audio RTP in the third data packet is sent to Port-a, the audio RTCP in the third data packet is sent to Port-b, the video RTP in the third data packet is sent to Port-c, the video RTCP in the third data packet is sent to Port-d, and the first mapping relationship is established, that is, the public network Port of IP1 maps the intranet Port of IP 3.

And after the second server cluster receives the first data packet, performing hash calculation on the address information of the first data packet to determine a first hash value, and under the condition that the first hash value is the same as the third hash value, the second server cluster sends the first data packet to the first server cluster according to a second mapping relation. Therefore, the fourth data packet is sent to the first server cluster through the target terminal, so that the first data packet of the target terminal received by the second server cluster is always sent by the second server cluster in the same session, the transmission of stream data through the same intermediate node is realized, and the source address received by the target server is ensured not to be changed in a complete session process.
To facilitate understanding of the technical solution in the data transmission method provided in the embodiment of the present application, please refer to fig. 9, and as shown in fig. 9, first, a target terminal and a target server register with a messenger server; when a session needs to be established, a target terminal sends a second data packet and a fourth data packet to a target port of a target server, and the target server sends a third data packet to address information of the target terminal so as to establish a first mapping relation and a second mapping relation; after establishing the first mapping relation and the second mapping relation, the target terminal sends N first data packets; the second server cluster receives the first N data packets and sends the N first data packets to the first server cluster according to the second mapping relation; and the first server cluster receives the N first data packets, and sends the N first data packets to a target port of a target server according to the first mapping relation to complete data transmission of the video conference.
Optionally, the second server cluster 802 is further configured to perform hash calculation on the address information of the target terminal 801 of the N first data packets to obtain a third hash value;
the second server cluster 802 is further configured to determine a first target server in the first server cluster 803 according to the third hash value;
the second server cluster 802 is further configured to send the N first data packets to the first target server.
It is to be understood that the first server cluster comprises a plurality of first servers, and that one SLB server of the second server cluster and one first server of the first server cluster are passed in between in the process of transmitting the N first data packets to the target server. In the data transmission process, in order to keep the paths transmitted to the target servers consistent, the second server cluster determines that one first server in the first server cluster is the first target server according to the third hash value, and then sends N first data packets to the first target server. The first target server sends the N first data packets to the target server after receiving the N first data packets, so that the N first data packets received by the target server are all sent by the first target server, and the consistency of the paths is guaranteed.
Optionally, the first server cluster 803 includes M first servers, where an association relationship is established between the M first servers based on a hash ring, where the hash ring is determined based on address information corresponding to the M first servers, and M is a positive integer greater than 1;
the second server cluster 802 is specifically configured to determine the first target server according to a corresponding pointing position of the third hash value on the hash ring.
The hash ring is a virtual ring node, and the second server cluster determines the first target server according to the hash ring.
Illustratively, as shown in fig. 3, M nodes are provided on the hash ring, and each node corresponds to one first server. Wherein the range of hash values is represented between each node. For example, there are 3 nodes on the hash ring, node R1, node R2 and node R3, the range of hash values represented between node R1 and node R2 is [0,100], the range of hash values represented between node R2 and node R3 is [100,200], and the range of hash values represented between node R3 and node R1 is [200,300]. And the second server cluster determines a first server corresponding to the node on the hash ring based on the calculated third hash value.
After the second server cluster determines the hash value, a node on the hash ring is determined. For example, it is determined that the third hash value is 150, and the hash ring position corresponding to the third hash value is between the node R2 and the node R3. At this time, a selection order is defined, and the closest node is selected as the node corresponding to the first server according to the order. For example, the selection is performed in a clockwise order, and the closest node is R3 at this time, that is, the first server corresponding to the node R3 is the first target server.
Optionally, an association relationship is established between the N first servers based on a hash ring and P virtual servers, a virtual server is arranged between the first servers having an adjacent relationship on the hash ring, address information of the virtual server is the same as address information of the corresponding first server, and P is a positive integer greater than 1;
the second server cluster 802 is further specifically configured to determine the first target server according to the corresponding location information of the third hash value on the hash ring and the P virtual servers.
It should be understood that the M first servers establish an association relationship based on the hash ring, and in the case that the second server cluster determines the first target server, there is a case that a certain node has more accesses in a set, so a virtual server is introduced based on this, so as to reduce the access amount of a single node.
Illustratively, as shown in fig. 4, three first servers establish association based on hash rings, and two virtual servers are added between each first server. The address information of the virtual server is the same as that of the first server, so that the second server cluster sends the N first data packets to the first server after determining the virtual server.
For example, the hash value range between node R1-1 and node R2-1 is [0,33], the hash value range between node R2-1 and node R3-1 is [34,67], and the hash value range between node R3-1 and node R1-2 is [68,100]. Wherein the range between the node R1-1 and the node R1-2 is still [0,100], corresponding to the ranges between the node R1-1 and the node R2-1, the node R2-1 and the node R3-1, and the node R3-1 and the node R1-2. The address information corresponding to the node R1-1, the node R2-1 and the node R3-1 is address information which is address information of the first server R1, wherein the node R1-1 and the node R2-1 are virtual server nodes. When the hash ring positions determined by the second server cluster are the node R1-1, the node R2-1, and the node R3-1, the second server cluster determines that the first target server is the first server R1, as shown in fig. 5.
It should be appreciated that the second cluster of servers includes a plurality of second servers, and one of the plurality of second servers is determined to be a second destination server, and the second destination server is configured to transmit the N first packets to the first destination server. The second server cluster determines the second target server through the third hash value and the hash ring, which is the same as the first target server determined through the third hash value and the hash ring, and is not described herein again.
Optionally, as shown in fig. 10, in a case that the first target server is abnormal and cannot transmit data, the target terminal sends a third data packet again for re-determining the first target server. For example, when the first target server is R1, the server R1 is abnormal, the target terminal sends the third data packet again, and at this time, the first server cluster determines the server R2 as the first target server again according to the hash ring.
In this embodiment, the target terminal retransmits the third data packet to determine the first target server, so that the first target server is replaced in the data transmission process, and the continuity of data transmission is ensured.
Optionally, as shown in fig. 11, in a case that the second target server is abnormal and cannot transmit data, the target terminal sends a third data packet again for re-determining the second target server. For example, when the second target server is L1, the server L1 is abnormal, the target terminal sends the third data packet again, and at this time, the second server cluster determines that the server L2 is the second target server again according to the hash ring.
In this embodiment, the target terminal retransmits the third data packet to determine the second target server, so that the second target server is replaced in the data transmission process, and the continuity of data transmission is ensured.
