s110, a room is created and/or joined in the client.
The room is a virtual room, a plurality of clients can join the same room, any client can create the room through touch control or other modes, the access authority of the room can be set after the room is created, and the client meeting the access authority can join the established room through application.
The method for creating the room at the client can be to create a new room by clicking a control corresponding to the created room, the method for creating the room at the client can also be to create a room instruction by voice input, create the room according to the room creation instruction, and the method for creating the room at the client can also be to acquire the brain waves of the user, generate a room creation instruction matched with the brain waves of the user according to the change curve of the brain waves of the user, and create the room according to the room creation instruction.
Specifically, the user can create a new room according to personal needs, or join an already created room.
And S120, after the at least two clients are successfully added into the room, NAT domain division is carried out on the at least two clients, wherein the connection mode of the clients in the same NAT domain is that the clients are connected.
The NAT domain is a storage area defined by a user, and clients in the NAT domain can all perform P2P connection and directly perform data transmission.
Specifically, after detecting that at least two clients successfully join the room, NAT domain division is performed on the at least two clients.
Optionally, after obtaining that at least two clients successfully join the room, performing NAT domain division on the at least two clients includes:
and after the at least two clients are successfully added into the room, the client is used as an intermediate server to perform NAT penetration between the at least two clients.
Specifically, after at least two clients successfully join the room, the server, as an intermediate server, performs NAT traversal on the clients joining the room.
And carrying out NAT domain division on the at least two clients according to the penetration result.
Specifically, the NAT domains of at least two clients are divided according to the penetration result, for example, if the penetration result indicates that the client a can penetrate and the client B cannot penetrate, the client a is divided into the first NAT domain and the client B is divided into the second NAT domain.
Optionally, performing NAT domain division on the at least two clients according to the penetration result includes:
if the client-side is successful in penetrating, performing P2P connection, and dividing the connection into the same NAT domain;
and if the client fails to penetrate, distributing the client into different NAT domains.
For example, if the penetration is successful, the different NAT domains are divided into the NAT domain a, and if the penetration is failed, the different NAT domains are divided into the NAT domain B, where the NAT domain B is different from the NAT domain a.
Specifically, after the at least two clients are successfully added into the room, the intermediate server performs NAT traversal between the at least two clients, if the client traversal is successful, performs P2P connection and divides the client into the same NAT domain, and if the client traversal fails, allocates the client into an inoperable NAT domain. For example, after the client a, the client B, and the client C successfully join the room, NAT traversal is performed on the client a, the client B, and the client C, if the client a and the client B successfully perform NAT traversal, the client a and the client B are divided into the NAT domain a, and if the client C fails to perform traversal, the client C is divided into the NAT domain B.
And S130, carrying out data transmission according to the NAT domain division result.

Example two
Fig. 2 is a flowchart of a data transmission method in the second embodiment of the present invention, where the optimization is performed based on the above embodiment, in this embodiment, performing data transmission according to the NAT domain partitioning result includes: when a data packet sent by a client is received, judging whether the data packet needs to be logically processed; if yes, performing logic processing; if not, the data packet is forwarded to any client side of the NAT domain different from the current client side.
As shown in fig. 2, the method of this embodiment specifically includes the following steps:
and S210, creating a room and/or joining the room at the client.
And S220, after the at least two clients are successfully added into the room, NAT domain division is carried out on the at least two clients, wherein the connection mode of the clients in the same NAT domain is that the clients are connected.

And S240, performing logic processing.
And S250, forwarding the data packet to any client of the NAT domain different from the current client.
The manner of acquiring any client in the NAT domains different from the current client may be to acquire the number of the current NAT domains in advance, and then forward the data packet to any client in each NAT domain except the NAT domain where the current client is located. For example, there may be a NAT domain A, NAT domain B and a NAT domain C, and if the current NAT domain where the client is located is NAT domain a, the packet is forwarded to any client in NAT domain B and any client in NAT domain C.
Specifically, the server needs to first determine whether the current packet needs to be logically processed, if so, the logical processing is performed, and if not, the packet is a common packet, the packet may be directly forwarded to any client in another NAT domain different from the current client in the NAT domain, for example, if the NAT domain where the current client is located is NAT domain a and currently includes NAT domain A, NAT domain C, NAT domain B, the server sends the packet to any client in NAT domain C and any client in NAT domain B.
In one specific example, the advantages of both the C/S mode and P2P are combined to allow direct connection between the client and the client, reducing server stress and processing of necessary packets by the server. The method comprises the following specific steps: the client creating the room and joining the room are handled by the server. After the client is successfully added into the room, the server is used as an intermediate server to enable NAT penetration between the clients, P2P connection is carried out after the penetration is successful, the clients are divided into the same NAT domain, and the server which fails in penetration is distributed to different NAT domains. The client broadcasts when sending data packets, the P2P client and the server connected with the client can both receive the data packets, some data packet servers which need the server to perform logic processing perform processing, and some common data packet servers do not need to perform a large amount of forwarding, and only need to forward one data packet to one client in different NAT domains.
In another specific example, the NAT domains are divided for the client, when the client sends a data packet for broadcasting, the client and the server in the same NAT domain receive the broadcast information, and the server determines that there are several currently existing NAT domains and sends the data packet to any client in a NAT domain different from the current NAT domain.
In another specific example, after a client a, a client B, a client C and a client D successfully join a room, the client a and the client B successfully penetrate, the client a and the client B are divided into an NAT domain a, the client C and the client D fail to penetrate, the client C and the client D are allocated into the NAT domain B, the client a broadcasts when sending a data packet, after the client B and the server receive the data packet, the server judges whether the current data packet needs to be logically processed, if the current data packet needs to be logically processed, the server performs logical processing, if the current data packet only needs to be logically processed, the server obtains the current NAT domain a and the current NAT domain B, and if the client a is a client in the NAT domain a, the server sends the data packet to the client C or the client D in the NAT domain B, if the data packet is sent to the client C, the client C sends the data packet to the client D through the P2P, and if the data packet is sent to the client D, the client D sends the data packet to the client C through the P2P.
According to the technical scheme of the embodiment, a room is created and/or added at a client; after acquiring that at least two clients successfully join a room, performing NAT domain division on the at least two clients, wherein the connection mode of the clients in the same NAT domain is that the clients are connected by the clients, and when receiving a data packet sent by the clients, judging whether the data packet needs to be logically processed; if yes, performing logic processing; if not, the data packet is forwarded to any client side of the NAT domain different from the current client side, so that the pressure of the server can be reduced, and more people can be supported to be online at the same time.
