In practice, because of their saturating affects, potentially all traditional transmission control protocol (TCP) congestion estimators effectively degrade the operational performance and efficiency of virtually all high-speed networks. Here the authors adopt a novel idea of using queueing-based estimator to estimate the TCP operating points ahead of their occurrence of network congestion. For this purpose the authors employ recent work of packet time-series analysis. In order to demonstrate the effectiveness of the idea, the authors embed the new estimator into several TCP variants in NS-2 and Linux kernel. For this evaluation the authors have programmed the simulation system to simulate a wide range of classic operating environments and setup many practical test-bed emulators for measurements. The authors results show that the idea of using a queueing-based estimator provides us far more earlier, sensitive and consistent estimation for the operating point than the classic loss/delay-based TCP traffic estimators. The authors then show that the new approach improves the overall estimation efficiency and provides higher performance and fairness when monitoring TCP traffic. [ABSTRACT FROM AUTHOR]
