DEVICE, METHOD, AND PROGRAM FOR ADJUSTING REQUEST LOAD, AND METHOD FOR COLLECTING PERFORMANCE DATA

摘要

PROBLEM TO BE SOLVED: To adjust server's loads caused by requests and to steadily set the controlled loads without stopping service provision by the server. SOLUTION: Requests transmitted to the sever 2 are temporarily stored in a queue 4, the requests existing in the queue or requests generated by a false client 5 when no request exists in the queue are successively transferred to the server 2 at prescribed timing to control server's loads caused by the requests. In this case, timing at which requests to be transferred to the server 2 arrive at the server 2 at fixed arrival time interval distribution is adopted as the prescribed timing. Such a timing is determined on the basis of random numbers generated from a random number generator 6 at prescribed probability distribution. COPYRIGHT: (C)2005,JPO&NCIPI
