Method, apparatus and communication system for estimating on-off traffic characteristic and recording medium recording program for estimating on-off traffic characteristic |
摘要 |
An ON-OFF traffic characteristic can be analyzed in real time from a measurement value without requiring detailed data analysis which is performed using measurement values accumulated for a predetermined time period through a high-performance measurement apparatus. A packet length and a packet transfer time interval of a communication traffic are first measured, and a data transfer rate variance indicator is computed based on a relative entropy value between the measured packet transfer time interval and a packet transfer time interval in case of transferring at a constant transfer rate. A predetermined traffic characteristic value is at least approximately computed using the computed data transfer rate variance indicator.
