Method and system for evaluating network performance

摘要

A scheme of evaluating performance of a network (34) connecting a remote terminal (12, 14, 16, 42) to a data service system (10) emulates a communication protocol to transfer data reliably and in sequence with congestion control. The communication protocol includes mechanisms for acknowledgement and retransmission and a dynamic window size. The scheme restricts the dynamic window size not to be greater than a predetermined maximun window size, and the amount of data transferred to a predetermined data transfer size, thereby accurately measuring user-perceived network throughput without significantly impacting network performance.
