Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 illustrates an exemplary system architecture, which may be a server 100, including a processor 110, a communication interface 120, and a memory 130, to which embodiments of the present invention are applicable.

The processor 110 is a control center of the server 100, connects various parts of the entire server 100 using various interfaces and lines, and performs various functions of the server 100 and processes data by running or executing software programs and/or modules stored in the memory 130 and calling data stored in the memory 130. Alternatively, processor 110 may include one or more processing units.

The communication interface 120 is used for communication and provides communication between banking systems.

The memory 130 may be used to store software programs and modules, and the processor 110 executes various functional applications and data processing by operating the software programs and modules stored in the memory 130. The memory 130 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required for at least one function, and the like; the storage data area may store data created according to a business process, and the like. Further, the memory 130 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

It should be noted that the structure shown in fig. 1 is only an example, and the embodiment of the present invention is not limited thereto.

Based on the above description, fig. 2 exemplarily illustrates a flow of a method for network communication according to an embodiment of the present invention, where the flow may be performed by a network communication device, which may be located in a server, and may be the server. As shown in fig. 2, the process specifically includes:

step 201, SESSION is acquired.

Here, the SESSION includes configuration information of the SESSION, a function pointer of the SESSION, and a link pair of the SESSION, where the link pair is an out link and an in link, and the link pair may also be said to include two SOCKET handles.

In the embodiment of the present invention, in order to monitor the simplex mode and the duplex mode in the link mode, both the simplex mode and the duplex mode may be regarded as two SOCKET handles, where the two SOCKET handles in the duplex mode are the same, and the two SOCKET handles in the simplex mode are different. Two SOCKET handles and associated configuration information are packaged as one SESSION. Specifically, the configuration information of SESSION includes one or any combination of the following information: the ID number ID, the out-link handle, the in-link handle, the link type, the association mode, the data protocol, and the secure transport protocol of SESSION may be specifically shown in table 1. The ID of the SESSION (SESSION _ ID) is a number of the SESSION, and the SESSION is managed based on the ID of the SESSION.

TABLE 1

Serial number	Properties	Type (B)
			1	SESSION_ID	Numerical type
2	Out-link handle	Numerical type
			3	In-link handler	Numerical type
4	Type of link	Numerical type
			5	Building connection mode	Numerical type
6	Data protocol	Numerical type
			7	Secure transmission	Numerical type

When managing SESSIONs based on their IDs, as one way of implementing the present invention, the IDs of SESSIONs may be stored in a memory for managing a predetermined number of SESSIONs. Specifically, the ID of one SESSION occupies 1 BIT, the value of the BIT may be 1 or 0, when the value of the BIT is 1, it indicates that the SESSION corresponding to the BIT is already allocated, and when the value of the BIT is 0, it indicates that the SESSION corresponding to the BIT is not allocated. For example, the size of the memory for storing the IDs of the SESSIONs is 1MB, and the 1MB of memory can store 8388608 IDs of SESSIONs, which is equivalent to 8388608 SESSIONs, that is, 16777216 SOCKET handles.

Step 202, initializing a function pointer of the SESSION according to the configuration information of the SESSION;

the obtained SESSION is allocated to a certain working thread of the thread pool, which may be specifically shown in fig. 3. The working thread is a manager of the SESSION, and the SESSION is loaded according to the configuration information in the SESSION. In order to enable the SESSION to support all link types and link modes and meet the requirement of secure transmission, all operations of the SESSION need to be abstracted into function pointers, as shown in table 2.

TABLE 2

Function pointer	Description of functions
		open_session_in()	Opening a snoop port
open_session_out()	Actively initiating a connection with the outside
		load_data_protocol()	Loading communication protocol
load_ssl_certificate()	Loading and installing communication certificate
		ssl_shake_hand()	Establishing SSL security lines
read_session_data()	Reading network data in SESSION
		send_session_data()	Sending data into the network through the SESSION

Initializing the function pointer of the SESSION according to the configuration information of the SESSION may be understood as providing a uniform function interface to the user through the abstracted function pointer, and initializing the function pointer of the SESSION according to the configuration information of the SESSION.

Step 203, calling a function pointed by the function pointer of the SESSION according to the initialized function pointer of the SESSION.

Here, the function pointed by the function pointer of SESSION is called according to the initialized function pointer of SESSION, thereby realizing different functions. Therefore, the adaptability of the communication mode can be realized, namely, the compatibility with different link types and connection establishing modes is realized, and the requirement of safe transmission is met.

After the function pointed by the function pointer of the SESSION is called according to the initialized function pointer of the SESSION, the working thread can manage the link pair of the SESSION based on the Reactor mode. Each SESSION is decoupled from the application layer by an internal ring queue.

When data is to be read, the data to be read is sent to the annular receiving buffer area, whether the data to be read in the annular receiving buffer area accords with a data communication protocol or not is judged, and if yes, the data to be read in the annular receiving buffer area is processed. Otherwise, whether the data to be read in the annular receiving buffer area accords with the data communication protocol is judged again until the data to be read in the annular receiving buffer area accords with the data communication protocol is determined, and the data to be read in the annular receiving buffer area is processed.

When data to be sent exist, sending the data to be sent to an annular sending buffer area, judging whether an external network is blocked, if so, judging whether the external network is blocked again, and writing the data to be sent in the annular sending buffer area into the external network until the external network is determined not to be blocked; otherwise, directly writing the data to be sent in the annular sending buffer area into an external network.

For a better explanation of the above embodiments, reference may be made to fig. 4. When the asynchronous mode detects that data are to be read, the data to be read are sent to the annular receiving buffer area, whether the data to be read meet a data communication protocol or not is not detected in the process, and therefore even if the received data to be read are incomplete data, the working thread cannot be blocked. When the data to be read stored in the annular receiving buffer area is read, starting a data analysis event, judging whether the data to be read accords with a data communication protocol, and if so, informing an application processing thread to process the data. If not, no processing is carried out, namely, the data is continuously kept in the annular receiving buffer area, whether the data to be read accords with the data communication protocol is judged again, and the application processing thread is informed to process the data until the data accords with the data communication protocol. Here, the application processing thread may be understood as a thread of a user or a user. Therefore, the asynchronization of network interaction is ensured, and the normal network interaction cannot be influenced by the processing of communication data.

And when detecting that data to be sent exists through the asynchronous mode, sending the data to be sent to the annular sending buffer area. When the data to be read stored in the annular sending buffer area is sent, if the external network is not blocked, the data is directly written into the external network; when the external network is blocked due to overlarge data amount or other reasons, whether the external network is blocked or not is judged again until the external network is determined to be not blocked, namely when the situation that the external network can write data again is detected through the asynchronous mode, the data is written into the external network again.

In the above embodiment, by initializing the function pointer of the SESSION and calling the function according to the initialized function pointer of the SESSION, different link types and link establishment modes can be compatible at the same time and the requirement of secure transmission can be met, and the beneficial effects are achieved: (1) the ID of the SESSION is stored in a memory to realize the management of a large number of SESSIONs, namely, a large number of link pairs are managed; (2) the pointer mode is used for managing the SESSION link pair, network event detection asynchronization and network data operation asynchronization are achieved, the problem that mass links are influenced mutually is solved thoroughly, and the stability of network communication is improved.
