عنوان المقالة:Performance Evaluation of Parallel TCP Variants and Its Impact on Throughput and Fairness in Heterogeneous Networks Based on Test-Bed Performance Evaluation of Parallel TCP Variants and Its Impact on Throughput and Fairness in Heterogeneous Networks Based on Test-Bed
It has been argued that single Transport Control Protocol (TCP) connection with proper modification can emulate and capture the robustness of parallel TCP and can well replace it. In this work, a test bed experiment-based Comparison between Single-Based TCP and parallel TCP has been conducted to show the differences of their performance measurements such as throughput performance, loss ratio and TCP-Fairness. In this experiment, Reno, Scalable, HSTCP, HTCP and CUBIC TCP variants, have been involved to show the differences in their performance and bandwidth utilization. On the other hand, the Link sharing Fairness has been observed to show the impact of using Parallel TCP of TCP variants with the existing single-based TCP connections. The results of this experiment reveal that: First: parallel-TCP strongly outperforms single-based TCP in terms of bandwidth utilization and fairness. Second: CUBIC-TCP achieved better performance than Reno, Scalable, Htcp and HStcp and for this reason it is (CUBIC) used as the default of Linux TCP variant in the latest versions of Linux like Fedora 10, 11 and openSUSE 11, 11.1.
