Embodiment Construction

[0030] For the software application system of C / S architecture, the communication method of named pipe is adopted to realize the network interaction between the client and the server. Physical structure diagram of network communication, such as figure 1 shown.

[0031] On the server side of the software application system, the high-performance server system proposed by the present invention is mainly composed of a communication interface layer, a message buffer layer and a business logic layer. The system architecture is as follows: figure 2 shown.

[0032] The interface layer is composed of a read thread and a write thread on the server side, and the message data is read and sent in an asynchronous manner, that is, two independent threads are used to read the client message and send the server message. Among them, the reading thread is mainly responsible for monitoring the named pipe connection request from the client, and receiving the request command of each client, and ...

Abstract

The invention discloses a thread pool based named pipe server concurrent communication method which comprises the following steps: 1, allowing a read thread at a server terminal to receive an operation request instruction from a client; 2, packing the received operation requests by the read thread to generate an input information which is saved in an input information buffer zone; 3, taking one piece of input information by a business logic thread pool , and performing corresponding operation according to the operation type defined in the information, after the completion of operation, packing the corresponding operation results by the thread pool so as to generate a piece of output information which is saved in an output information buffer zone; and 4, when a write thread at the server terminal detects the output information in the output information buffer zone, acquiring the output information from the queue, and feeding the corresponding operation result to the corresponding client according to the communication mark in the information. According to the invention, with two threads, data reading and sending between the client and the server can be realized, so as to ensure the reliability and real-time performance of the system.

Description

technical field [0001] The invention relates to a server concurrent communication method based on a client / server, and belongs to the technical field of computer software. Background technique [0002] At present, most application system software is based on the two-layer structure of client / server (Client / Server). Using this architecture can make full use of the advantages of the hardware environment at both ends, and reasonably allocate tasks to the client and server, thereby Reduce the overall overhead of the system. In the case of a certain hardware configuration, the performance of the server-side software is crucial to the performance of the entire software application system. [0003] The performance of the server is reflected in the following aspects: [0004] One is the speed at which the server responds to the client, that is, the real-time nature of communication; the other is the concurrency performance of the server, that is, how many clients can simultaneousl...
