Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a hardware system to which the present invention is applied and is a relation diagram for communication in a client-server architecture environment having a different connection environment.

As shown in FIG. 1, a hardware system to which the present invention is applied includes a client process 11 and a server process 13 for communicating in a different environment having a server structure requiring a single connection with a client requiring multiple access. Intermediate process (12) acts as an intermediary in the middle of the process.

The client process 11 has a structure in which each of the client threads 111 has multiple connections, and the server process 13 has a structure supporting only a single connection.

Each process 12 is composed of a response message receiving thread 121 that receives a response from the server process 13, and client corresponding threads 123 that communicate with each of the client threads 111 of the client process 11; have.

Each process 12 has a response message receiving thread 121 that receives the transmission result from the server process 13, and the client corresponding threads 123 for multiple connection of the client process 11 are client threads 111 Is dedicated to sending information to the server process 13 via a single connection.

When the client correspondence threads 123 are connected from the client process 11, the client corresponding threads 123 generate an event and include the event value in the message sent to the server process 13, and the server process 13 receives the same event in the received response message. The intermediary process 12 is sent to include the value. At this time, when the response message receiving thread 121 receiving the result from the server process 13 generates an event with an event value in the received response message, the corresponding client correspondence thread 123 receives the event and sends the event to the client process 11. Send a response message.

FIG. 2 is a diagram illustrating an embodiment of a communication method between a multiple access client and a single access server according to the present invention, and the client process 11 requiring multiple accesses sends information to a server process 13 allowing only a single access. Shows the procedure for sending and receiving a delivery confirmation message.

Each process 12 is composed of a response message receiving thread 121 receiving the transmission result from the server process 13 and a daemon thread 122 waiting for the multiple connection request of the client process 11.

Looking at the communication method between a multiple access client and a single access server according to the present invention.

The intermediate process 12 connects to the server process 13 (201), and generates a daemon thread 122 and a response message receiving thread 121. Here, the response message receiving thread 121 of the generated intermediate process 12 enters the standby state to receive the response message after connecting with the server process 13. The daemon thread 122 also waits for a connection request from the client process 11.

If the client process 11 requests a connection (202), at this time, a client thread 111 is created in the client process 11, and the daemon thread 122 is waiting for the client request thread 123 (203), and the newly created client correspondence thread (123) generates one event and includes the generated event value in the message to be sent to the server process (13) and sends it to the server process (13). 204, wait for an event to occur with the event value.

On the other hand, after the server process 13 receives the message from the intermediary process 12, if the event value included in the message is included in the response message and transmitted back to the intermediary process 12 (205), the intermediary process 12 The response message receiving thread 121 in the response stores the received response message in a wide area memory and generates an event with an event value stored in the response message, so that the corresponding client waiting for an event to be generated with the corresponding event value among the client response threads 123. Event 206 is sent to thread 123. At this time, the client corresponding thread 123 reads the response message from the wide area memory and transmits the response message to the corresponding client thread 111 of the client process 11 (207).

3 is a flow chart of an embodiment of a communication method between a multiple access client and a single access server according to the present invention, wherein different communication is performed between a client process 11 requiring multiple access and a server process 13 supporting a single access. The following shows information transmission and transmission confirmation procedures in a connected environment.

At this time, the response message receiving thread 121 of the generated intermediate process 12 is connected to the server process 13 and transitions to the standby state to receive the response message (303). The daemon thread 122 also waits (304) for a connection request from the client process 11.

Thereafter, when a connection request is received from the client process 11 (305), in the wait state for the connection request (304), the daemon thread 122 generates a client correspondence thread 123 (306). At this time, the generated client correspondence thread 123 generates one event for the connection of the client process 11 (307) and includes the generated event value in the message to be sent to the server process 13, the server process (13) After transmitting to the network (308), it waits for the event to occur with the corresponding event value (309).

Next, the server process 13 includes the event value included in the message received from the intermediary process 12 in the response message and sends it back to the intermediary process 12. Thus, the response message from the server process 13 When received (310), the response message receiving thread 121 in the intermediary process 12 stores the received response message in the global memory (311), and generates an event with the event value stored in the response message (312) to respond to the client. The event is transmitted to the corresponding client corresponding thread 123 waiting for an event to be generated with the corresponding event value among the threads 123 (313).

Subsequently, the response message 314 reads the response message from the wide area memory in the client correspondence thread 123 and transmits the response message to the corresponding client thread 111 of the client process 11 (315).

As described above, the present invention provides a communication method in a heterogeneous communication environment between a multi-access client and a single-access server, so that a system that supports only one connection from one information system and a server system must be communicated through multiple connections. It is suitable for heterogeneous communication environments between client systems with a task of nature.
