摘要
分析和研究了事务处理系统的响应时间的分布规律,得出平均响应时间与呼叫强度成指数关系的结论.首次提出用线性回归的方法自动检测事务处理系统过载检测点,该方法不依赖系统的具体实现,能根据系统的负荷的大小自动实现过载检测.此方法应用于智能网业务控制点(SCP)的自适应窗口控制算法中,实验结果验证了其具有很好的自适应性和有效性.
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 control point has good adaptability and validity.
