    It has been demonstrated that as the per-flow product of bandwidth delay increases, TCP becomes inefficient and unstable, regardless of the queuing discipline. By decoupling utilization control from fairness control, the eXplicit Control Protocol (XCP) outperforms TCP in both conventional and high bandwidth-delay environments. In this article,. we present an efficient flow control scheme based on XCP for high bandwidth-delay product networks. It can shorten the response time and improve the performance of XCP. Simulation results show the effectiveness of our proposed scheme in several performance aspects. Moreover, its implementation is simple enough to fulfill the required criteria of high bandwidth-delay product networks.

    In the large bandwidth-delay product (BDP) networks, it has been demonstrated that the eXplicit Control Protocol, XCP, outperforms TCP and remains efficient, fair, and stable. However, once a packet drop is detected, an XCP's congestion management should follow TCP's Van Jacobson congestion control. In other words, congestion window should be halved and the fast retransmission/fast recovery, congestion avoidance algorithms should be applied. In the mean time, congestion window should be reduced by the value of the negative feedback. In this article, we present a smart window adjustment scheme for XCP's congestion management to shorten the response time and improve network performance.
