Abstract:

Distribution characteristics of the response time in transaction processing systems were studied and analyzed. The conclusion shows that the mean response time goes by the exponential trend with the change of the call intension. A linear regression method was proposed for the first time to detect automatically the overload detection point of the transaction processing system. It implemented overload detection adaptively according to the load of systems, and was independent of system structures. The results of the experiment show that this method applied in an adaptive window control algorithm of the intelligent network service contr ol point has good adaptability and validity.

Key words: overload detection, linear regression, overload control, service control point
