The design of serial server based on semaphore under Linux

On the basis of analyzing the disadvantages of a general-purpose method for the server program design, a new method of the serial server program design based on the semaphore in Linux is introduced. Then, an implementation framework proposed by this paper is depicted. The number of the child processes which produced by the server that designed by this methods will no longer have a linear correlation with the cumulative number of the client requests, but only related with the peak value of the clients at a certain time. So this proposed method can remarkably improve the operational efficiency of the server.
