  Parallel Transport Control Protocol (TCP) has been used to effectively
utilize bandwidth for data intensive applications over high Bandwidth-Delay
Product (BDP) networks. On the other hand, it has been argued that, a
single-based TCP connection with proper modification such as HSTCP can emulate
and capture the robustness of parallel TCP and can well replace it. In this
work a Comparison between Single-Based and the proposed parallel TCP has been
conducted to show the differences in their performance measurements such as
throughput performance and throughput ratio, as well as the link sharing
Fairness also has been observed to show the impact of using the proposed
Parallel TCP on the existing Single-Based TCP connections. The experiment
results show that, single-based TCP cannot overcome Parallel TCP especially in
heterogeneous networks where the packet losses are common. Furthermore, the
proposed parallel TCP does not affect TCP fairness which makes parallel TCP
highly recommended to effectively utilize bandwidth for data intensive
applications.
