TCP becomes inefficient and unstable in high bandwidth-delay product networks. The eXplicit Control Protocol (XCP) is an explicit protocol, which can acquire efficiency, fairness, stability and low queue length in wired high bandwidth-delay product networks. However, the simulations conducted under the Geostationary Earth Orbit (GEO) satellite networks context in this paper show that the utilization of the XCP bottleneck is low. To address this problem, a modified variant of XCP, MXCP, is proposed in the paper. MXCP uses Loss Differentiation Algorithm (LDA) which is based on the queuing delay of the bottleneck to differentiate the reason of packet losses.
