[0045] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] like Figure 1 As shown, the present application provides a multiplexing management method for connecting multiple streams with a single port, including:

[0047] S1. The session management module reads the peer configuration information and initializes the session for the memory management module, network transmission management module, CST protocol management module and multi-channel flow management module according to the peer configuration information;

[0048] S2. The network transmission management module starts a loop to read and write data, and at least two threads or coroutines are started at the same time, wherein one thread or coroutine is responsible for receiving network packets, and the other thread or coroutine is responsible for reading the data input by the application layer and transmitting the data to the CST protocol management module;

[0049] S3, the CST protocol management module parses the data to obtain structured data in the CST protocol format;

[0050] S4, the multi-channel flow management module identifies the structured data in the CST protocol format and initializes the flow state;

[0051] S5. Determine whether the ID exists based on the identified CST protocol format structured data;

[0052] S6. If it does not exist, the identification flow is established successfully;

[0053] S7. If it exists, read the application data and store the application data into the memory management module.

[0054] As described in the above steps S1-S7, the TCP / IP protocol stack is used to establish a link, and all data transmissions use CST protocol packets, including: a session management module, a memory management module, a network transmission management module, a CST protocol management module, and a multi-channel stream management module, thereby realizing single-port connection multi-channel stream multiplexing management based on TCP / IP; specifically, when reading the configuration information of the other end, the external end configuration information is read, the IP and a single port are set, the TCP / IP protocol stack is used to establish network communication, and the network connection is initialized; according to the end configuration information, the session mode is set, the server end sets the server mode, and the client end sets the client mode, and according to the maximum number of streams parameters and the memory initialization parameters, the stream management, memory management, and transmission management are initialized, and finally the initialization of session management is realized. The CST protocol management module can unpack the read network packets and also perform CST protocol encapsulation on the user input data. All the data after unpacking and encapsulation is structured data in the CST protocol format. When the multi-channel stream management module identifies the structured data in the CST protocol format, the stream management state machine identifies the flag value of the CST protocol header and determines the status of the stream based on the predefined flag value. The status includes: new, successful connection, completion and disconnection. According to the CST protocol ID value, the ID of the stream is confirmed, and hash mapping management is performed based on the ID. The actual structural data area of ​​the stream is quickly found through the ID. According to the value of the CST protocol length, the actual user's application data or user data is read and written into the memory management module.The multi-channel stream management module identifies the CST protocol flag field and initializes the stream state according to the flag field definition; creates a new stream request, queries the stream management hash mapping table, takes the maximum ID, the new ID value is the maximum ID + 2, and sets the CST flag to 0x01, notifying the CST protocol management to process the stream creation request packet and set the stream state to new; obtains the ID field value, searches the stream management hash mapping table for the ID value, if it does not exist, it is successfully established, notifies the CST protocol management that the response flag field is 0x02, indicating that the stream is successfully established, if it exists, directly reads the application data, stores it in the memory management, and sets the stream connection success state; wherein, the CST flag value is 0x02, indicating that the stream connection is successful, and sets the stream connection success state; wherein, the CST The flag value is 0x04, which indicates that the stream is disconnected. The stream status is set to disconnected, and the resources of the hash management corresponding ID are released. The memory management module presets the maximum value of the memory that can be used to 16MB, and the initialization default value is set to 256KB. The server and client can negotiate the stream acceptance memory value according to the CST protocol type value 0x02, but it is not allowed to exceed half of the maximum value of the configured memory to ensure that multiple stream connection resources are available at the same time, and at the same time can store data after CST protocol unpacking or packaging. In this way, this embodiment can improve port utilization efficiency and reduce server resource usage without increasing port resources or repeatedly opening and closing ports, while realizing multiple data stream requests or initial launches at the application layer, thereby improving the application layer experience speed.

Specifically, the preset value is 0x01 to identify data, indicating data transmission, 0x02 to identify window, indicating updating the transmission data window size, 0x03 to identify ping, indicating detecting the RTT value of the network between the server and the client, and 0x04 to identify goaway, indicating interrupting the connection session; set the protocol identifier flag, root According to the set identification value, the definition of the data flow status is formulated, which occupies 2 Bytes. Specifically, the preset value is 0x01 to identify SYN, indicating that a signal is sent to create a new flow; 0x02 to identify ACK, indicating that the response value of the new flow signal is received and the new flow connection is successful; 0x03 to identify FIN, indicating that a half-close signal is sent to the established flow, which can also carry user data; 0x04 to identify RST, indicating that the connected flow is closed; set the protocol flow identifier, that is, the protocol flow ID, and confirm the ownership of the identified flow according to the actual value of the ID. Set the service flow ID value to an odd number and the client flow ID to an even number, which occupies 4 bytes. Set the data length identifier lengh, the actual algorithm is: length = S12 + S13 + S14 + S15 + S16 + actual user data length, occupying 4 bytes; protocol application data and user data, the length is not limited; after the CST protocol management module parses the data, it reads the CST protocol header data to implement the structuring of the network data packet; and determines whether the ver field is supported to implement whether the network packet is valid; reads the type field value, determines the type value to identify the corresponding function, and performs corresponding function processing, among which 0x01 identifies the transmission data, 0x02 identifies the update protocol memory, and 0x 03 identifies the RTT of the detection network, 0x04 identifies the interrupt chain; read the flag field and determine the flag data value, where the flag data value is: 0x01: identifies the newly established stream; 0x02: identifies the receipt of the new stream request response ACK; 0x03: identifies the sending of a half-close signal to the established stream, which can also carry user data; 0x04 identifies RST, indicating the closing of the connected stream; S405 identifies the state of the stream according to the field value read in S404 and the corresponding identifier; S406 reads the ID field to identify the ID of the stream; S407 reads the length field to identify the application layer data length;

The memory management module presets the maximum value of the memory that can be used to be 16MB, and the initialization default value is 256KB. According to the CST protocol type value 0x02, the server and the client can negotiate the stream acceptance memory value, but it is not allowed to exceed half of the maximum value of the configured memory to ensure that multiple stream connection resources are available at the same time, and can store the data after the CST protocol is unpacked or packaged.
