[0023] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation method of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0024] The technical solution of the present application and how to solve the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0025] An embodiment of the present invention provides a UDP-based many-to-one data stream orderly transmission system, which is suitable for UDP communication, such as multimedia news release, online live broadcast, online advertising, e-commerce, video on demand, distance education, telemedicine, online radio, real-time video conferencing, etc. Figure 1 The UDP-based many-to-one data stream orderly transmission system includes: n first devices and one second device. The first device is a client device, and the second device is a server device. The first device and the second device can be computers, tablet computers, terminals or handheld devices according to actual needs.

[0026] When using the UDP protocol for many-to-one communication, the UDP server will sort the IPs that need to be subscribed, and send the data transmission rule information in order to the specified client, that is, UDP client IP No. 1 is sent to UDP client IP No. 2, sent to UDP client IP No. 3 - until it is sent to UDP client IP No. n. This purpose is to tell the client that it needs to send data to the server of another client. Before each client receives data, it will determine whether the data type is the IP address in the rule file. If not, it will not be processed. When the data of the first UDP client is sent to the second UDP client, the second UDP client will splice the data packet of the second UDP client after receiving the data of the first UDP client, and send it to the next UDP client together, until the last UDP client sends its spliced ​​data to the UDP server.

[0027] The second device generates a data transmission rule according to the data subscription service and sends it to multiple first devices. The data transmission rule includes the data transmission order of multiple first devices related to the data subscription service. Each first device receives a UDP data packet according to the data transmission order, and generates a new UDP data packet in combination with its own UDP data packet. Among them, if the current first device is the first first device according to the data transmission order, a new UDP data packet is directly generated according to its own UDP data packet; otherwise, the UDP data packet sent by the previous first device is received, and the received UDP data packet and its own UDP data are spliced ​​and combined to generate a new UDP data packet. Then the new UDP data packet is sent to the next first device or the second device according to the data transmission order. Among them, if the current first device is the last first device according to the data transmission order, the new UDP data packet is sent to the second device; otherwise, the new UDP data packet is sent to the next first device that is located after and adjacent to the current first device.

[0028] For the aforementioned n first devices and one second device, according to the data transmission order, the first first device directly generates a new UDP data packet based on its own UDP data, and sends it to the second first device. The second first device generates a new UDP data packet based on the received UDP data packet sent by the first first device and its own UDP data. The second first device sends the generated new UDP data packet to the third first device. And so on, until the nth first device receives the UDP data packet sent by the n-1th first device. Then the nth first device splices the received UDP data packet with its own UDP data to generate a new UDP data packet, and sends the new UDP data packet to the second device, completing many-to-one UDP data transmission. In this way, the orderly transmission of UDP data can be achieved, the quality of UDP data transmission can be improved, and timing errors can be prevented during UDP data transmission, which is beneficial to subsequent UDP data processing.

[0029] like Figure 2 FIG. 1 is a flow chart of a UDP-based many-to-one data stream orderly transmission method provided by an embodiment of the present invention, which is applied to a first device. The method includes:

[0030] Step S11: receiving a data transmission rule sent by a second device, where the data transmission rule includes a data transmission sequence of a plurality of first devices related to a data subscription service.

[0031] UDP data packets include: data type (1 byte unsigned char), sender IP (4 bytes unsigned int), send time (8 bytes unsigned long), data buffer size (4 bytes unsinged int) and data buffer data (usually 1316 bytes).

[0032] Before step S11, the current first device is automatically started and a fixed port for receiving UDP data packets is configured. When the fixed port needs to be changed, the port number of the fixed port is modified; the current first device is automatically started according to the modified port number, and the fixed port is updated.

[0033] Step S12, receiving a UDP data packet according to a data transmission sequence, and generating a new UDP data packet by combining the UDP data packet itself.

[0034] If the current first device is the first first device according to the data transmission order, a new UDP data packet is directly generated based on its own UDP data; otherwise, the UDP data packet sent by the previous first device is received, and the received UDP data packet and its own UDP data are spliced ​​and combined to generate a new UDP data packet. It should be noted that each first device receives UDP data packets through a configured fixed port. The sending port used to send UDP data packets is random.

[0035] The data transmission rule also includes the IP addresses of multiple first devices. Before step S12, it is determined whether the sender IP in the UDP data packet is consistent with the IP address of the first device corresponding to the data transmission rule. If they are consistent, the step of receiving the UDP data packet sent by the last first device is performed; otherwise, the UDP data packet is not received.

[0036] Step S13: Send the new UDP data packet to the next first device or second device according to the data transmission sequence.

[0037] If the current first device is the last first device according to the data transmission sequence, the new UDP data packet is sent to the second device; otherwise, the new UDP data packet is sent to the next first device that is located after and adjacent to the current first device. In this way, many-to-one UDP data transmission is completed, and disordered UDP data communication is converted into ordered UDP data communication, which can solve the problems of timing disorder caused by disordered transmission of UDP data communication in the prior art, disorder when using data, and network congestion, realize the orderly transmission of UDP data packets, effectively improve the quality of UDP data transmission, and facilitate the use and processing of subsequent UDP data packets.

[0038] The embodiment of the present invention receives a data transmission rule sent by a second device, where the data transmission rule includes a data transmission order of multiple first devices related to a data subscription service; receives a UDP data packet according to the data transmission order, and generates a new UDP data packet in combination with its own UDP data packet; wherein, if the current first device is the first first device according to the data transmission order, a new UDP data packet is directly generated according to its own UDP data packet; otherwise, a UDP data packet sent by the previous first device is received, the received UDP data packet and its own UDP data are spliced ​​and combined to generate a new UDP data packet; the new UDP data packet is sent to the next first device or the second device according to the data transmission order; wherein, if the current first device is the last first device according to the data transmission order, the new UDP data packet is sent to the second device; otherwise, the new UDP data packet is sent to the next first device that is located after and adjacent to the current first device, thereby achieving orderly transmission of UDP data and improving the quality of UDP data transmission.

[0040] Step S21: Generate a data transmission rule according to the data subscription service, where the data transmission rule includes a data transmission sequence of a plurality of first devices related to the data subscription service.

[0041] The data transmission rule is generated based on the data subscription service, including the data transmission order of multiple first devices related to the data subscription service. The data transmission rule includes the IP addresses of the multiple first devices, and the data transmission order can be represented by the sorting order of the IP addresses of the multiple first devices. Of course, it can also be represented in other ways, such as IP address combination equivalence, which is not specifically limited here.

[0042] Before step S21, the second device is automatically started and a fixed port for receiving UDP data packets is configured. When the fixed port needs to be changed, the port number of the fixed port is modified; the second device is automatically started according to the modified port number to update the configuration of the fixed port.

[0043] Step S22: sending the data transmission rule to multiple first devices.

[0044] The second device applies a random sending port to send the U data transmission rule to each first device.

[0045] Step S23: receiving the last UDP data packet sent by the first device according to the data transmission sequence.

[0046] The second device receives UDP data packets through the configured fixed port. The second device receives the UDP data packet sent by the last first device in the data transmission sequence. The UDP data packet received in this way includes all the UDP data packets that the multiple first devices need to send to the second device, and because the UDP data packets of each first device are transmitted in order according to the data transmission sequence, the subsequent second device can conveniently and orderly use and process the received UDP data.

[0047] The embodiment of the present invention generates a data transmission rule according to a data subscription service, wherein the data transmission rule includes a data transmission sequence of multiple first devices related to the data subscription service; sends the data transmission rule to multiple first devices; and receives a UDP data packet sent by the last first device according to the data transmission sequence, thereby realizing orderly transmission of UDP data, improving the quality of UDP data transmission, and facilitating the use and processing of received UDP data.
