A method for concurrent communication of named pipe server based on thread pool

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...

AI Technical Summary

Problems solved by technology

The header of the UDP message is only 8 bytes, the overhead is small, and the transmission is faster than TCP, but the order of the data cannot be guaranteed, and there is a possibility of packet loss.

[0011] It can be seen that the communication method using socket, whether it is TCP or UDP, has its own advantages, but there are also disadvantages that cannot be ignored.
