Abstract It is known that congestion in the reverse direction happens in advance of the
congestion in the forward direction due to the significant bandwidth asymmetry
in the two directions of the space networks, especially in the satellite networks,
which enables the TCP Vegas to enter the phase of the congestion avoidance
blindly and reduce the throughput of the forward direction. To solve this
problem, a congestion control model, TCP Vegas-DDA, which maintains the
frequency of the acknowledgments in the reverse direction is proposed. The
model sets the interval time between acknowledgments dynamically based on
